Marlin reverse motor direction. This results in X movements when joggin Y and vice versa.

Marlin reverse motor direction Since there is no convention you just need to play with it. At least with Repetier you can. The Reverse direction of motors (INVERT_X_DIR) We will modify these parameters if when doing a HOME or when printing any part with our printer, any of the motors goes in the . Number the wires from left to right so they go one to four, switch wire one with two. The motor be up to the jerk speed between the third and fourth reverse direction steps. I’ve To swap X and Y movement reverse direction of one motor (any one) Just turn the stepper plug around if you can (while off!) Edited 2 time(s). Stainless steel motors are built and designed for longevity and low maintenance. h file and replace:. Download the firmware and open the firmware project in Arduino IDE. Navigate to the "Steppers" section of the pins_RAMPS. 0x. Get these right without belts attached first, if possible. but when I give the stepper a -ve value it still runs forward. 0 # Maximum rate in mm/min Marlin 3D Printer Firmware . I've switched the direction and switched back in Marlin several times now. 2 as firmware. U1, U2, V1, V2, W1 & W2 are the motor leads L1, L2 and L3 are the supply cables To reverse the motor, any 2 of the supply cables should be changed over. I am trying to configure Marlin 2. Return the extruder and order one that works with the stock motor direction. I use an Ender 5 frame, so the endstop is at max position (220 x 220). On my machines i am running ramps1. One additional update: So then motor stoped to work but aftet ESC calibration in Mission Planner, motor started to work but direction stay the same as it was. Calibrate the extrusion. But the problem is that when the nozzle should go up it goes down and when the nozzle should go down it goes up. h and found that the dual X and dual Y had the reverse motor option. Sensorless homing works fine and If you have to set INVERT_?_DIR is a matter about how you plugged your stepper. I am using the Marlin 2. That could occur when: cable connectors to stepper motors are reversed, or the motor is assembled the other way (you can set reverse direction in Marlin) SKR V1. Change the Esteps to a negative number. If I reverse the sign on the SCALE for Y, it changes the behavior of the CoreXY. DC motors use a permanent magnet for the field part. Q&A. 0 with built in tmc2209 drivers, when homing a second time or when going to auto bed level after homing, x and y axis start from where z safe homing position is at the center of my bed (150,150) thinking its a 0,0 position and crashes as it thinks it at 0,0 when it starts to auto bed level but its actually at 150,150. New motor config looks like: Hi everyone! 0,0,0 is the left front corner at the surface of the bed. If it's Marlin firmware, the direction is defined in the firmware and can't be changed by gcode commands. Before testing, move the carriage and bed to the middle. I'm not 100% sure how Marlin will handle large negative values but in theory it should work. #define INVERT_X_DIR true // DELTA does not in So all my motor spin in the same direction, so I need to change the motor direction of my motor 2 and 3. Is the reversing motor running smooth? Any mechanical resistances? Is the stepper turning "powerful" when turning backwards? Are the motors different? Are the drivers different? Is any of the parts hot? You can do that in Marlin (easy) or via hardware (not recommended). While I know Marlin can do it, I don't know how as it was the first thing I replaced. h to reverse extruder motor direction. The hardware part works Fully tighten in clockwise direction with appropriate spanner ensuring that lid is not cross threaded. There might be more issues, but I gave up when I saw this. Reply reply Top 1% Rank by size . You @noxx2015 — Contrary to the advice from @opy001, you don't need to add any Z2 pins to the RAMPS file. cpp but that part of the code including every reference to the encoderDirection variable appears to have been They motors moved in the opposite direction that I had wanted so, Version of Marlin Firmware. Basic Information: Printer Model: Ender 5 plus MCU / Printerboard: btt skr mini e3 v3 klippy. Also: I cannot move the head below zero on the Z Change (or reverse the motor connector) if an axis goes the wrong way. I was using firmware provided by the Lyman/Mulier project for filament extrusion on Thingiverse: [www. This will reverse the motor direction as the coils order are Reverse Direction of Stepper. h where you can set the place and offsets of homing and switch the movements to go in the other direction. Plug Stepper Back In. If The sign is not I have problem with my extruder motor. That will reverse the motor direction. the right one) and plug the If I invert my X and Y I should reverse the direction of the engines if I do not touch the endstop what would be the same. The variable is true or false. Expected behavior. I tried reversing the four motor wires after struggling with the connector for a while and that seems to have worked, but my printer is still freezing whenever I try to extrude (which also has the interesting side effect of causing the hotend to keep heating up so that it's 10-20 degrees hotter than what I set it at by the time I get it restarted which I think lead to the thermal runaway It doesn't seem to be a way to reverse a second X2 motor from the software. Test each axis for proper movement using the host or LCD “Move Axis” menu. 7. Then it moves back down towards the bed a little, and then moves up again for the second (more accurate) To change direction you need to reverse the current in one set of coils only. The setting is in the LCD Menu under Settings. all my bigger machines like 4ft by 8ft and 5ft by 10ft machines i have been wiring in separate tb6560 stepper drivers wired into the x axis. There are two things that can affect motor travel when homing. Keep reading for more Unplug the motor from the board and flip it around. Insert TMC2208. The strange thing is that if I set the letters above to "true, it still doesn't change direction. Standard throttle with one direction setting or neutral position with forward and reverse. Marlin Firmware PlatformIO Motion Coordinates Archive Archive Wiring The Steppers Dual Endstops Milling Metal Import Extruder Reversing a Stepper XLoader Repetier-Host Arduino G-code V1pi - Headless Reversing the Axis Direction ¶ If your steppers are moving together but This video is about inverting the direction of a stepper motor, easy and quick. Code; Issues 652; Pull requests 64; Discussions; Actions; with LA activated the extruder motor do not reverse. Maybe you forced it in backwards. Add Heatsink. define INVERT_X_DIR true define INVERT_Y_DIR true define INVERT_Z_DIR true "This is where you need to switch the values around. If you swap the poarity of both coils, that cancels out. I need to change the direction of a stepper motor, I know that the wiring is connected to the A+, A-, B+, and B-. My machine Homes Z by raising all way up (and hits limit sw). ----- // Invert the stepper direction. hotend • You will need to re-compile Marlin. Just install it and test motor direction like always and reverse if needed. I actually just had to do this because I installed a bondtech extruder, which uses a reverse motor direction. log Describe your issue: I made a homemade direct drive mod with the stock motor of my Ender 5 plus. If you simply enable REVERSE_MENU_DIRECTION and disable If we SWAP motors A/B on the board so that they are wired with A to motor 0 and B to motor 1 the x and y home and move in the correct direction. (Qi Hi just got my Tevo , assembled , powered everything seems to work , but when homing the bed moves forward away from the end stop , the extruder carriage moves to the left and just chatters , doesn't trip the end stop . I edited the section in marlin firmware: // Direction of endstops when homing; 1=MAX, -1=MIN // :[-1,1] #define Description All motors are running in reverse direction. Whatever x and y are Here are a few ways to reverse the direction of an extruder motor: Reverse the wiring. #define INVERT_X_DIR false #define INVERT_Y_DIR true #define INVERT_Z_DIR true // @section extruder // For direct drive extruder v9 set to true, for geared extruder set to false. Go to the printer. Marlin-bugfix-2. I wrote up a simple explanation of setting up Re: GT2560 A + PWM fan connection and reverse direction June 18, 2023 12:55PM Admin Registered: 14 years ago Posts: 7,160 Unlike a 2 motor machine, I cannot reverse the probe order, because "reversing" a correction would require moving two other motors, not just one. Key variable is #define INVERT_E0_DIR. eg. Or if you swap the coils over, A for B, you reverse the direction. In your config. Replace your stepper motor. In the Marlin Firmware it specifically says that DELTA does not invert for the stepper direction. When i under heavy development for the past couple of months and moving to it's last mile to finish the RC cycle and release Marlin v1. I am using the the stepper library in Arduino. There will be a line which is showing a dir_pin, if there is an '!' before the pin name like this: dir_pin !PB6 Remove the '!' sign. I tried to INVERT_X_DIR / INVERT_Y_DIR In a nut shell this reverses all of the E directions used, whether you're using relative or absolute extrusion. I haven't got the touch screen going The direction on TMC2208 is reversed compared to A4988. r/MarlinFirmware. Turning counter-clockwise moved the cursor (and the numbers) downwards, so I've used the The configuration with marlin 2. controlled by CNCjs on a PI3B+. I'm using a proximity sensor LJ12A3-4-ZBX and an MK3 Heated Bed. There are #define statements to reverse stepper motor directions in the configuration. I was using firmware provided by the Lyman/Mulier project for filament extrusion on Thingiverse: Marlin just seems to want to home the opposite direction that it is set to. thingiverse. Reply reply Hi! Not sure how or why it happened, but since downloading and installing the custom firmware for my CR-10 S5 the extruder runs in reverse. Last value is cached for future invocations. This gives the best dimensional accuracy but may cause marks to appear in the print. Be careful when first setting these. h> // with stepper J835S: from h-bridge 1-out = orange, 2 = // Invert the stepper direction. If I set INVERT_Y_DIR to 1, it doesn't change the Y direction since this is a CoreXY. ; At this time the direction bits for Z and Z2 have to match, so if you find that E1 goes the wrong direction, you should just Motor direction can also be changed by rewiring the motor cable. #include <Stepper. In case of three phase induction motor, they are self-started There is a known bug on betaflight 4. 5 Config Reversing Stepper Direction when adjusting feedrate and mixing stepper #21724. Add Comment. If I set it to home to min, it homes to max. h all of my changes are bounded by #ifdef ChuckMod. Don't flip the connector, take the pins out. So you need to swap two wires/pins in the connector. So if it was already set up for normal motor installation and you flip it to the bottom of the frame, you have to reverse the motor direction. As Howard mentions Marklin uses 0-16 volts AC to run the trains with a 20 volt pulse to reverse the direction. Swap pins 1 and 4 OR pins 6 and 3 on the female JST connector that plugs into the extruder motor. Many people have already had the trouble but I found no answer apart for the debug of the three probing point. At the moment the two motors are connected in parallel and turn in the same direction. 1 but wanted newest auto leveling and other bells and whistles. It has something to do with the update from marlin you updated too. 2 iirc that won't let you change the motor direction from betaflight, you could try doing it from the esc configurator or rolling back to 4. h) in response to Z_DUAL_STEPPER_DRIVERS. I am using an H-bridge and have tried all combination to wire my 4 wire 9V stepper motor. Now i am wanting to Ive updated the firmware to Marlin 2. the motors have individual drivers, so the Second motor is connected to the extruder 1 motor driver (configured to work as Secondo z axis) Could build your own based on the most recent marlin, either 1. The homed Z position in Marlin is then I tried setting the axis up to home to a max position but this produced the same issue- the only way I could get the axis to home towards the min was by inverting it's direction in the firmware so that it was homing in the - direction to meet a maximum point- when told to print this produced the same problem, the machine would home and then continue to move My extruder motor turns the wrong way. Application example(s) The machine has a selector switch to changeover between a vertical and a horizontal spindle. It'll now spin the other way. Be sure to restore the stepper leads to their original positions if you do that though. To get the motor moving in the right direction, is actually does matter which coil is which and what the polarity of the coils are. Problem is that each time I try Z_TILT_ADJUST rather than getting better, the front left corner seems to get visibly worse and worse until the process fails on the 2nd or 3rd attempt. The A and B motors should plug into the X and Y axis motor connectors, respectively, on the controller board. The Winsinn BMG clone for $13 on Amazon will work. you do need to reverse the stepper motor direction for the BMG compared to the original extruder. I am currently looking at the code with my father and am looking for a solution. It shows the two simplest methods of how you can invert an axis, extruder, et Swapping the two center wires should normally work. I’ve set the rotation distance I need to change the direction of the extruder stepper motor, and would rather not flip the plug upside down. Which two wires to switch is a bit more tricky unless you know the pinout of both the board and motor connector (I refrain from guessing since others probably have experience with this particular setup). [extruder] step_pin: PB3 dir_pin: There is a place in configuration. Got it. The position_endstop and the dir_pin. 4 shields Since I’m using the probe to home the Z axis, and Marlin doesn’t allow me to invert the Z homing direction with the probe. The right solution nowadays is taking the wires out of the plug of the stepper motor connector using a prying tool and switching them A Switching Extruder is a dual extruder that uses a single stepper motor to drive two filaments, but only one at a time. if I set it to home to max, it homes to min. Either the S or W parameter must be given, along with X and Y positions. Everythings work fine except there will always be one axis running at the reversed direction. If yours are in the front, you may need to reverse the directions. If you change the This is just a query. The servo is used to switch the side of the extruder that will drive the I kept looking through the marlin website for a gcode command to reverse the stepper motor direction, but I couldn’t find it. the left stepper) and connecting the other end to the MB ‘Z’ plug, then, connect another separate harness from the other ‘Z’ stepper (e. 3 obviously). 4 with arduino mega2560 using modified marlin firmware. Re-assemble your Motor direction. Bug Timeline. I had a problem with changing the direction of a stepper motor. x Printer: Tronxy x5s. Pick one of the following in order to reverse the stepper's direction: X moves when both motors turn the same direction Y moves when both motors turn in opposite direction if you want to invert Y movement, you have to swap X and Y stepper motors to each others plugs on the controller (Never do this while it has power!) Edited 3 time(s). h and set the number of Z steppers to 3 in the Change in ESC configurator in ESC1-4 field Normal->Reverse. when controlling the machine manually with the LCD controller every thing moves in the correct direction as it should. The Y axis direction is inverted. I recently bought a Rotor Riot Tanq and built it. #define X_STEP_PIN 54 #define X_DIR_PIN 55 #define The printer's origin (0,0,0) can be located literally anywhere but the directions of increasing ordinate values must be in the proper orientation for right-hand-rule coordinates or your prints will come out mirrored because the CAD software that designed the print used right-hand-rule coordinates. Almost done! Re-assemble your printer and enjoy near silent (fans make some noise) printing! Conclusion . However the two axis are inverted this way (X is front to back while y is now Electric motor 101. The generic config had the rotation as ‘8’. To change the motor wiring, just get some tweezers and lift the plastic that holds the metal pin in for the 1st and 4th pin, and just swap them. On the Prusa fork this line doesn On Marlin the check for the REVERSE_MENU_DIRECTION happens in the ultralcd. I have tried inverting stepper direction (which just makes it move opposite of requested move direction). If you don't have the Bondtech, maybe it somehow reversed otherwise. which you are supposed to uncomment. Your print is growing as the bed goes down. After the fourth reverse direction step the stepper will be accelerating normally. Z axis, post a picture reverse the stepper motor connector on the RAMPS like Firmware is probably the better option since its easy to change, and it will give you a bit more knowledge on how it is configured. It worked but not correctly. Just installed the third (back) axis today and am trying to get z-tilt to work. #define INVERT_X_DIR false #define INVERT_Y_DIR false #define INVERT_Z_DIR true----- It hasn't anything to do with creality. Steps to Reproduce Since the motor outputs are wired the other way around with TMC drivers, the stepper motors would now run in the wrong direction. Look for how to reverse a stepper motor (via wiring) instead. My conclusion is there'll be a loss of two steps. Reversing the Y motor (or X motor) causes the Y and X axis motions to be interchanged. Change (or reverse the motor connector) // if an axis goes the wrong way. the x y and z Bug Description I have a custom built 3D printer with Marlin 2. I am having same issue with skr mini e3 v2. MarlinFirmware / Marlin Public. Printer model. Im using a cr10 with Marlin 1. Compile and upload the sketch. Any suggestions. Luckily, Marlin has an absolutely brilliant The Marlin FW, did that come from Creality or was that put together by 3D Printing Canada ? If that was the case, they did not configure it right. News and information related to the Marlin Firmware used on many 3D printers around the world. Z moves wrong direction when home marlin 1. More posts you may like r/MarlinFirmware. 1 mm has the motor driving the bed in the right direction but the moment I go higher the motor direction reverses. h but that didn't work. You can also change the direction in SW (assuming Marlin, it is INVERT_E0_DIR in Configuration. h of Marlin 2. The system is seeing them as always on so the movement you see is Marlin bumping off the endstop. Whether I tell it to extruded or retract it always retracts, regardless of how I have Marlin set. X moves correctly, but I need to invert the Y direction. [Y<direction>] 1 for positive, 0 for negative. The pins for Z2 will be auto-assigned to the first free extruder plug automatically (in pins. If I try to home the X or Y axis the machine goes away from the endstops. Do you have the Bondtech extruder? There's an option to set the direction of the extruder, which is necessary for the Bondtech. 5 # X stepper motor current alpha_max_rate 30000. 2) Like depicted in photo below, setup#1 is general Hi, I'm working on a project involving a platform moving along a threaded bar in both directions. In order for it to work, the motor rotation directions have to be set correctly, limit switches have to be plugged into the right sockets on the I've set up a printer with CoreXY structure with Marlin-bugfix-2. In Marlin Configuration. Unplug wire from back/side of motor, hold plug in your fingers with the 2 tabs pointing up. People typically set the origin up at the left-front (L-F) corner (X increases as the You have to change motor direction in Marlin. There are a couple of settings in the Marlin configuration files that determine home Before the reset, the motors moved to both sides, positive and negative. Change (or reverse the motor connector) In this section you have to adjust the direction of the stepper motors matching you version of a 3d printer. 9 bug fix branch and I have defined all three steppers in the configuration. 1. 7 TMC2209 with sensorless homing on XYZ. The firmware used is based on the Marlin FW, and the motors responded as per Marlin configuration. I have enabled Z axis Reverse Z and Relative Z moves I have also included a start up GCode that homes, turns on inline mode and sets Z to the desired height: G28 G1 Z140 F2000 M3 I S0 After getting an operation set - MOST of the time the system runs properly. Steps to reproduce Direct swap of creality default board to the SKR mini V2 Install ender 5 firmware from BTT repo. While there isn’t a G-code specifically made for reversing the extruder direction, we are able to perform this task by applying a small trick to another command. This seems to be intentional and is documented even in the comments on Amazon listings. And it can not be configured by any of existing variables. To prevent this from happening, we install The 4 pin cable connected to your board can be connected in the opposite order by making an 180° rotation. I have all the stepper motors working as well as end stops, hot bed, hot end, and fans. However when I move it backwards, it does not come back, it is stopped. I'll leave this up for posterity. Also you can change the direction in your firmware. you could revert back to original firmware configuration and M906: Stepper Motor Current; M907: Trimpot Stepper Motor Current; M908: Set Trimpot Pins; M909: Report DAC Stepper Current; M910: Commit DAC to EEPROM; M911: TMC OT Pre-Warn Condition; M912: Clear TMC OT Pre-Warn; M913: Set Hybrid Threshold Speed; M914: TMC Bump Sensitivity; M915: TMC Z axis calibration; M916: L6474 Thermal Warning Test Extruder 0 , Axis X/Y only moves in 1 direction all time. Also account for stepper direction in the firmware, and endstop configuration. I would expect that because changing the axis SCALE value inverts the motor and changes the kinematics. Invert the motor's movement. Search for INVERT_E_DIR. What firmware are you running? If you are using klipper you can put a carat in front of the stepper pin in printer config to reverse it. Reply reply Motor moving the wrong direction. Research that. Original should have the two middle wires crossed. I have modified the G34 code to invert the correction direction, and I Unlike corexy, direction of X-axis in H-bot can be reversed depends on position of belt clamp. #define INVERT_E0_DIR true #define INVERT_E1_DIR false The title pretty much about sums it up. The issue isn't that it is reversed, the issue is that it is ALWAYS reversed. Here below is an Been using marlin 1. #define INVERT_X_DIR false K value calibration is a lot like the junction deviation value calibration, we print something with varying values and see which works best. h). Dual steppers for X and Y Looking for a way to invert extruder_stepper dir_pin from gcode command currently I am making macros to sync extruder stepper to the extruder, extruder_stepper direction is tool dependent (T0&T1 in the same After the updates of 2023-05-05 I see different movement direction for Z2 and my X axis doesn't reverse direction anymore. I have even tried reversing the plugs on the stepper motors. Axes moving the wrong direction can cause damage. Marlin: origin/bugfix-1. However, when I sent the firmware to the Arduino, I can only rotate the motors on all axes only to one side. 4 Board (Apparat from "Motherboard" changed ro skr 1. It's an IDEX system with i3 design. Reverse the plug. Im not sure how or what to change. as per Marlin, the homing for X shall move towards the left side and for Y to the back of the printer. Perhaps one could put in negative step numbers but that is not a way I wanted to go. com]. (reverse) As the title states, my machine homes in the wrong direction. Change (or reverse the motor connector) if an axis goes the wrong way. (rel 1. I'm changing the line: #define INVERT_E0_DIR false in configuration. Creality ships these boards with different stepper drivers. You can't simply reverse one motor's direction without considering the rotation of the other to make things move the way you want. Not used for directional formats. It's The direction of rotation of the spindle motor changes for the following functions: • M3 • M4 • M5 • SPOS/M19/SPOSA from the motion; not effective for SPOS/M19/SPOSA from zero speed (stationary). #define INVERT_X_DIR true At first I thought the results looked wrong. The G28 command should send the extruder carriage toward the endstop switches. Lay the stepper end connector with pin removal side up swap left most wire with third from left wire should reverse direction. 6 i cant mechanically change the extruder stepper for some reason so i need to do it in marlin. g. [Z<direction>] 1 for positive, 0 for negative. I then looked at config_adv. Cancel Post comment. But if I try to use the wizard or individually option of "change motor direction" then after testing the motors still spin in the wrong direction // Invert the stepper direction. // Invert the stepper direction. I want to re-do it, but your server just says the builds “failed” (I see the previous poster is having the same problem). Old. Whenever I press the reverse button, it does not reverse which direction it is moving. using a bed probe sensor or a min Z endstop, you This video teaches how to reverse the feeding direction of an extruder by swapping the wires of a stepper motor cable that connect to one of the stepper moto Trying to swap a stepper motor but its spinning the wrong way? dont worry this will be a quick fix with out going to much into details. 3 with Marlin 2. Notifications Fork 18. This results in X movements when joggin Y and vice versa. There For common small induction motors it may be easiest to reverse the motor rotation direction by swapping the motor start capacitor leads in front of or behind the auxiliary (start) winding. Last edit at 02/25/2017 03:35AM by Dust. I tried reversing the red and black, For a 4-wire NEMA stepper, the pairs are red/blue, and green/black (or brown/orange and red/yellow). 9 or marlin 2. Ive tried manually moving the x axis to see if that makes any difference and noticed that movement below and including 0. . which is why it only goes in one direction, Induction motor are categorized by two types, one is single phase induction motor and another one is three phase induction motor. The platform should first reach the interrupt limit switch(pin 2), the rotation direction should then switch to take the platform to the other limit switch(pin 5). 1k. 4. x if you're feeling sassy. If you want a motor to reverse you swap 2 of the cables to the esc. then 3 with 4. Compile your own firmware, making the appropriate change in Configuration. You really should fix the issue at the firmware level, though. The motor will come to a halt, maybe even start slowly in the reverse direction when the second reverse direction step occurs. What I had to do was swap the physical motor cables, which gave me reversed X and Y, then invert the direction settings in the config. So to reverse the direction, either swap pins 1 and 2 at the board end (4-pin connector), or swap pins 3 and 4 at the board end, or turn the plug round so effectively swapping pins 1 and 2 with 3 and 4, or swap pins 1 and 4 at the Description. The W parameter exists only when Z_STEPPER_ALIGN_STEPPER_XY is defined, providing known stepper positions. IE, it sees the endstop and bump off it and stop cause they still see it so it only goes the bump distance off a false indication. x bugfix. #define INVERT_E0_DIR false #define INVERT_E1_DIR false # So you replaced the stepper motor and it is original wiring but running backwards. 2. Behave like before, correct/unchanged axis movement HI, I am trying to get my stepper motor to run forward and backward. If these are wrong, your prints will be backwards on the bed. h . Could modify your plug to be able to reverse it, or use some male to female dupont connectors to that way you don't need to Hi guys. By default, steps are added to the first segment after a direction change. Motor now runs the correct way. Backlash compensation will add extra steps to one or more segments whenever a motor reverses direction. Is something like: // Invert the stepper direction. #define INVERT_Z_DIR true Furthermore, it matters where the Z endstop is located, e. In the firmware I understand that I need to add an ! Like so (!PB1) And it doesn’t reverse, so I removed it to see if that’ll work. Direct bin install, no local compilation. 5k; Star 15. Thanks in advance. Sanity check - double check the E0 motor connection. Edit . Add a comment . I have been building my 4ft by 4ft machines using dual y stepper drivers and dual y stepper motors running marlin. After killing power, reverse the connection on one motor and try again. Didn't invert, or Marlin couldn't build. But on a closer look, actually value editing is correct. Which corrected stepper motor directions to the proper orientation. As Marklin uses AC current there is no permanent magnet as there is with DC trains and instead there are coil windings for both the armature and field parts of the motor. First, I've uploaded the firmware without changing any options related to the direction of the encoder. define INVERT_X_DIR true define INVERT_Y_DIR true define INVERT_Z_DIR true "This is where you need to switch Here is a video: https://youtu. if y is reversed and As far as I can see on the attached videos your homing movement is reversed. Bought a new Octopus board because I am running a Core XY machine with 3 Z steppers. See my other EDIT: Solved! Big thanks to u/An_Alex_103 for pointing me in the right direction. If you did do that, but the extruder motor was running in reverse for both extruding and retracting directions, I would download Marlin and set the reverse option for that motor to true in the configuration file. Motor direction needs to be the same as normal motor installations and match the configurator diagram. Is that reversing correlated to high speeds on the z-axis? Play with z-speed and z-acceleration, z-jerk. For marlin you can open your config file and change the line "#define INVERT_E0_DIR" to be the opposite of what it currently is, "TRUE" becomes "FALSE" and vices versa, without quotes. We suggest you to try out the latest RCBugfix branch and I know the printhead is supposed to move up a little bit and stop, and then move down to start the first part of the homing, touch the bed, move back up, and back down again for the second, more accurate probe. I am trying to reverse the motor direction on some of my motors, as only one of the motors is spinning the right way. be/WqAs_putTmk. Actual behavior. On the printer display, I go to the option to move the axis, rotate it 10 mm and the axis moves. 0. These settings reverse the motor direction for each axis. h file. How can I reverse the direction of the Y axis on a CoreXY? My X axis homing switch is on the left side, and Y homing switch is in the rear. ender 5 plus. The 1. Specifically, to reverse the direction of the motor: swap pins 1 and Progress ! Sorted the stepper direction issue and the limit switches work as they should. Electronics. But instead, it moves down a little, then up until I trigger the probe. The next one to sort is the Z-Axis speed. --- You may also want to check a couple of things on your motherboard. By running the M92 (Set Axis Steps-Per-Unit) G-code and passing the negative of the current steps-per-unit as the value for the axis parameter you See more I have a (HIC) version of the Prusa i3. The endstop position determines which direction the motors go to get to the endstop. It still doesn’t. h and configuration_adv. I have recently installed the E3D v6 hotend and titan extruder. When I comment the tag //#define If your motors move the wrong direction // uncomment the option the axis that needs reversal and then re-upload the firmware to the printer. I tried to set up my dual extruder but the problem is that the second extruder (E1) stepper motor is not moving at all. Now having problems that simply looks like a beginners mistake // Invert the stepper direction. The one way that should work doesn't do anything. 4 release and the 2. Currently What is the problem? I bought a fastbot bbp 1s a couple years back and have just now hooked it up. #define INVERT_X_DIR false #define INVERT_Y_DIR false #define INVERT_Z_DIR true // @section extruder // For direct drive extruder v9 set to true, for geared extruder set to false. Any suggestions ? Thanks folks When using Marlin firmware you could easily change the pin layout of the extra extruder (E1) with the broken X stepper pins by changing the pins_RAMPS. h you can switch the boolean option from FALSE to TRUE or vice versa. In Marlin, you change the direction of an axis by modifying: # Pin for alpha stepper direction, add '!' to reverse direction alpha_en_pin 0. A Z of 10 is 10mm up from the base of your part no Set an XY probe or known position for a given Z Stepper. I went into the firmware and loaded the firmware to the robo r1+ with 8mm rod firmware marlin file and still has the same issue. Assuming you have the 0,0 position in the correct location, if you tell it to move X and the Y axis moves, one of the motors is reversed. Install using SD card I need to change the direction of the extruder stepper motor, Controversial. 4 # Pin for alpha enable pin alpha_current 1. All you need to do is to reverse the direction in Marlin (lines 850 onwards in configuration. On standard Marlin there is a line, //#define REVERSE_MENU_DIRECTION. Printer starts print normal, but in some time he change direction of extrusion Extruder reverse direction in middle of the print - Problem April 14, 2016 01:17PM No everything is ok, no shorting, or demons or something like that I use marlin firmware, cura software and ramps board if that helps And also used Marlin successfully in the past. The Ender 6 is a [X<direction>] 1 for positive, 0 for negative. If you have to set ?_HOME_DIR to +1 or -1 is a matter of if you are homing towards a min or max -endstop/homing-switch. Also electric motor 101 Don't leave wires exposed like they are on that xt60 I mean unless you like lipo fires Quad RE: Extruder on reverse. I tried the E1 direction in config. I'm using Marlin RC7 and I enabled Auto Bed Leveling Grid option. Some people commented that it's in the manual, if this is something that was added in a newer firmware please share. The individual motors are not X and Y motors. -----// Invert the stepper direction. Most everything works using the BOARD_CREALITY_V4 definition, however, the X axis does not home or move in the correct X+ direction. // Reverse ALL motor directions //#define REVERSE_ALL_MOTOR_DIRECTION // Reverse specific motor directions (these are all enabled if you uncomment REVERSE_ALL_MOTOR_DIRECTION in the backend). After fixing some other issues, I noticed that there is no filament being You cannot use M92 E-on Marlin (anymore). If they are currently true, change them to false and if they are false In some places they use the term X2 but in others like reverse section (around row 1645 in config) it isn't labeled that way. On my first time using Marlin, in the 2. Members Online. If you do, it's easy. Swap Yeah this doesn't exist on the PF525, PF7 series have a parameter for reversing motor leads to switch the motor direction relative to fwd / Rev inputs of the drive. You won't need to The simplest way is to simply set a flag when menu navigation is active, clear it otherwise, and only reverse the encoder direction in software (in the manner that @TechMasterJoe and I point out) when that flag is set. Home is left rear corner with Z moving up. I have a drawing where I have show the movemen that will reverse the motors. I'm currently running TMC2208_stand alone (its working ok) driver because the stepper driver it says i have (H8) HR4988 is unrecognized in marlin Config. Good to know, and a good reminder that one should actually test things occasionally. Controversial. The motor direction is clockwise when looking at the shaft, Heh, apologies GeertB and thank you Nophead! I did the experiment, and yes, reversing the stepper motor plug does reverse the stepper direction. https: Since both motors are in use for any move in the X and Y axis, I will reference the motors as "LeftMotor" and "RightMotor", with the assumption that both motors are in the rear of the printer. Tried 2 differents RAMPS 1. However, right below that the Z didn't have it. You'd have to either edit the firmware or physically reverse the polarity of the stepper motor coils. However, if they're wrong, the motor just turns the wrong way, it's easy to fix that by swapping wires. 2023-05-05, 2023-05-03 worked as expected. 0 is exactly the same as the one that was working on the 1. Right now I've found no way to change the direction of a single axis with a COREXY: the INVERT_#_DIR flags invert the motor movement, but in a COREXY this I fixed Marlin firmware and now I have: // Invert the stepper direction. There must be some setting I chose in the custom firmware build that has caused this condition. The platform is restrained by two limit switches at the end of the assembly. config file and find the Z stepper motor which is turning the wrong way. You can reverse the direction by switching red and blue, or green and black. Closed jameswis01 opened this issue Apr 25, 2021 · 6 comments Closed Provided config files shows CONFIGURATION_H_VERSION 020006 This is a Your looking in the wrong direction. Don't think of actual part directions, but as how tall your part is and how high up in the build is the nozzle. h of Marlin, But the Axis have XY axis have now swapped back Please can someone assist me with this problem. Other Just reverse the connector to the RAMPS board on the X Axis and it will move in the opposite direction. x newest firmware. Can be top or side mounted; Motor Size: LEM 200-D135: LEM 200-D135: LEM 200-95: LEM 200-D135: Voltage: 48V: 48V: 48V: 48V: Current: 120 Amp: 180 Amp: 220 Amp: Connect a single harness to each ‘Z’ stepper motor (e. 2 for the relatively new Ender 6. My question is which of these am I supposed to swap to make the motor switch and rotate in the opposite direction. coil - and it doesn't matter which - you reverse the direction. Attached is my configuration. (It sometimes gets bad enough to pull the screw coupler on the motor off). Extruder 1 , Axis Z works fine in both direction; I changed stepper drivers but always Extruder 0, Axis X/Y were moving in same direction all time. Last edit at 04/30/2014 06:21AM by Dust. I've tried to invert the direction in configuration. During this process the number of steps When i reverse the menu navigation with REVERSE_MENU_DIRECTION, only the menu item direction changes but not the value editing. ahdv mbiwi ottiap zqkdvu iygk zxgk owskbj env mhueglmr khor
