Since it seems to be localized to specific hardware. I varied sensitivity from 0 to 250, but nothing changed. And here it's important to not … that would indicate the endstop was plugged into the wrong socket, wouldn't it? but I continue to have random failure on homing. Using Marlin firmware and pronterface. If stepper drivers time out, X and Y homing will be required again. If you are intimidated by that, then watch Tom's firmware guides. Not an essential step to clearing home offset, put the 3d printer in a safe position by homing each axis after powering up the printer. Compiled actual bugfix version and changed homing direction to ymin. I try downgrade to 0.5.2, but the behavior is quite the same for me. Y axis not auto homing [Solved] Y axis not auto homing Last Post RSS leonajos (@leonajos) Active Member. I believe this is likely solved for anyone using mechanical switches, and the remaining issues are only related to sensorless homing. Subject: Re: [MarlinFirmware/Marlin] [BUG] No homing of y-axis against ymin (. homing is working. Changing it to home on Ymax would indicate that the Y endstop is plugged into the Ymax pins, right? Has anyone attempted to determine the cause, or is the workaround satisfying enough? My second problem is gone, z moves now flawlessly. I am using ramps 1.4 board. Homing to y-max helped him too (facebook group conversation). Tried Repetier firmware and this issue did not occur, but there I have issues setting up other things. Took my time for several days. Drivers on xyz TMC5160 Also changed the inverting in the configuration.h back to false. but when homing the bed moves forward away from the end stop , ... Just reversing the motor to be on the other side of the Y axis is by far the simplest. So _CAN_HOME is working fine. It travels to the end of the stroke in Y- and then moves about 6 inches in the Y+ direction before indicating via the position readout that it is now at X0 Y0 Z0. a good solution would be nice for people with this board "bigtreetech Gtr v1.0". For the first G28 after Marlin is restarted and "clean", the extruder will move to the centre of the bed and then go down until the Z endstop is triggered. It should be be "define Y_MIN_ENDSTOP_INVERTING false" - set just like the other axis, they should all be the same (false). I also him a bigtreetech gtr v1.0 Recently i updated my 3d printer MKS GEN L v1.0 Board with Marlin 1.1.9.everything working fine Except Homing.when try to home any axis its not going correct direction its going in opposite direction.so i searched for solution internet gone through forums and etc.finally i found solution in reprap.org forum .in this forum they discussing about similar problem.

This issue has been automatically locked since there has not been any recent activity after it was closed. on Repetier Host. @Minims (and anyone else with problems with sensorless homing on CoreXY), I suggest you look at issue #16420, as it seems very much like the issues mentioned here. I may look for mechanical switch. I'm not sure how to disable homing on only one axis. TLDR: The Y axis moves the correct way in manual control but moves the wrong way (toward the max, not the min, away from the limit switch) during homing. I was using Sprinter firmware but it dosnt support auto bed level, so thus im stuck using marlin. the frame is made from this: https://www.thingiverse.com/thing:971110. all of the inner parts for X axis are using the Prusa i3 MK3 parts. I only have the home switches activated for the X and Z axis. but it has work without issue since 6 months :/ I will look at all my bearing that may alter sensorless homing. Same wiring, same pins definition, with older marlin it works and homing to y-min is working with newer marlin not. The Z axis homes upward for some reason, occasionally it will look the right way but not go down far enough. Is it a power issue? Cc: Ian K Nicholas ; Comment Ma last version was from the end of April. When I give the homing command to Y-axis, it jerks towards the Y+ ( and moves like 5mm towards the y-max position) I am using regular SKR 1.4 Board and (Not the turbo one) a lot of compilation to do :-). thanks for your effort i would like to see a solution, I can't find any readable documentation for that board. But if I had one I would try reversing the port numbers in the pins file The Z will move up and down twice, then the X and Y axis will move. Why use BLTouch / 3DTouch? Have a Awea machine with Fanuc O-M controller. Only changes I made to the bugfix version was steps per mm, speed, bltouch offset, the basics, nothing else at time of configuration, no sensorles homing used tmc5160 setup, single nozzle.

Sorry, there are about 3 of these going right now so I got confused - my normal state. X, Y axis move fine (to right and back when adding +10 on the axis). Configuring Endstops on Ramps 1.4 With Marlin Firmware - @section Homing : This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands (G-codes). https://yoruichi.golf-4-cab.de/nextcloud/index.php/s/Fs2CSNNEzaczZdY, https://github.com/bigtreetech/BIGTREETECH-GTR-V1.0/blob/master/BTT%20GTR%20V1.0/manual/GTR%20V1.0%20PIn.PDF, https://yoruichi.golf-4-cab.de/nextcloud/index.php/s/qZzT4GPxd4N8fj9, https://github.com/notifications/unsubscribe-auth/AEAZK2BYFYJAFSN7IREZEXLRZHUORANCNFSM4NVYMRDA, [BUG] Sensorless homing on a COREXY with SKR1.3/TMC2130 failed, https://github.com/notifications/unsubscribe-auth/AEAZK2C6GIF6GJQKRIFZVZTRZMH2ZANCNFSM4NVYMRDA. 0,0 is on left bottom of the Buildplate, as usual. Y axis I designed my own parts for, but they work fine, I've already tested the printers movements using Sprinter firmware. Everything else for the operation of endstops should be the same between mine and yours. Compare the old and new pins files. This will tell you if the pins file is correct, and it will tell you whether any pins on your board are shorted or cut. That looks correct. What endstops did you build for X and Y?

In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? I can tried to debug this, but I need help to add log in the right space for example so I … So what I'm going to do is reducing the sensorless homing sensitivity to … Not really. However when bed levelling this causes an issue where the probe or nozzle can not … As a side-effect, X and Y homing are required before Z homing. Please provide more information: what printer/board are you using? Enter the g-code M501 in the terminal interface text box. I should note I have A LOT of printer building experience, at least 20+ printers. Press the send button to send the g-code to the 3d printer. The pin file didn't changed the whole time! Have a question about this project? I didn't use sensorless, i've used microswitches tried with NO and NC connection, only switching to ymax helped. On the Y axis I have the direction moving correct in pronterface, but when I press home it moves about 1cm in the wrong direction and stops. And will open a new issue for this z axis problem. Make sure the current limiting trimpot on the X axis pololu (and the second pololu you swapped out with) isn’t set too low.

Sign in #define Y_MIN_PIN PC13 If it is working for you with mechanical switches, I think that we should try to re-open #18391 to track the sensorless issue, since the original issue reported here is fixed. Maybe someone can point me in the right direction. [BUG] Printer Halts and Requires Restart During Attempted Auto-Home. Otherwise, it is another issue. I have tried all the variations of marlin that are on their website for download and none of them work correctly for me. G28 disables bed leveling. Did you update something and it got less reliable? The documentation could be found here: I ended up giving up. As a side-effect, X and Y homing are required before Z homing. Please open a new issue for related bugs. I use repeiter host but i downloaded printerrun jsut to see what would happen and it had the exact same effect/ errors. Right now, G28 first lifts Z by 10mm, homes X and Y, and then tries to home Z, but since there is no endstop it would push the spindle into the wasteboard and probably rip itself apart. When this option is enabled you can use M43 to watch one or more pins, or monitor the endstop pins, and it will report their state as you touch / trigger them. Have now other troubles with this shitty GTR board. I can activate the limit switch by hand when Y is moving and machine will home. Even if I gave in and put the endstop on the -Y side, I don't understand why homing … Anybody know what I’m doing wrong?

My Z axis the only axis that has a stallguard capable stepper driver, so I need to find a way to disable sensorless homing on X and Y. I am trying to get sensorless probing to work, so I can't cut the DIAG1 pin and just use a mechanical endstop. I then contacted your support on Aliexpress and you said to try sending command M122. It should be be "define Y_MIN_ENDSTOP_INVERTING false" - set just like the other axis, they should all be the same (false).
