M914 X55 stops without reaching the end of the rail, whereas M914 X54 hits and grinds at the end of the rail for ~4 seconds. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. I seem to have solved the issue by increasing the HOMING_BUMP_MM and enabling SENSORLESS_BACKOFF_MM as follows: I've lowered these values, and they seem to be working fine. Auto-home one or more axes, moving them towards their endstops until triggered. * Higher values make the system LESS sensitive. This is reported by not only myself, but another member of the "BIQU SKR Owners Group" over on Facebook: https://www.facebook.com/groups/247860246136776/permalink/331864144403052/?comment_id=332138477708952&reply_comment_id=333026657620134&comment_tracking=%7B%22tn%22%3A%22R%22%7D, https://www.facebook.com/groups/247860246136776/permalink/331864144403052/?comment_id=332138477708952&reply_comment_id=333041497618650&comment_tracking=%7B%22tn%22%3A%22R%22%7D. Confirming this is an issue for me as well. * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. If you'd like me to diagnose further, just tell me what I can test, I have no idea where to start. Have a question about this project? But X and Y values are always set to 0 after initilisation (Power on or Reset) while M122 command shows default values defined in Marlin. In this video, I show you how to configure Marlin 2.0 for the SKR 1.3 mainboard with TMC2209 stepper drivers and sensorless homing. Just testing again today and IMPROVE_HOMING_RELIABILITY doesn't seem to make much difference (except for slowing the bump process down slightly - assuming to make it more accurate). The humback whale is relatively robust rorqual and can reach up to 16 m in length. The impossibility of safe automatic sensorless homing. Especially the 'Additional difficulties with Quick- and DELTA- Homing.' It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. I hit this issue while setting up my new SKR 1.4 Turbo with TMC2209s using the bugfix branch at 10601a9. It's possible the issue only presents itself the first time you've enabled TMC5160 in config. Start high, for example M914 X192 Y192 and then decrease the value until it only triggers when bumping the end of the rails. The text was updated successfully, but these errors were encountered: Here's a clearer video of the behaviour: https://photos.app.goo.gl/LBgrf79Hmc3Cm9Js7 * It is advised to set X/Y_HOME_BUMP_MM to 0. i will let it stay here then, i dont use sensorless homing so i cant confirm it. X axis should hit the endstop softly and register the stop immediately. Changing the source code and re-flashing the firmware does not change the contents of EEPROM. Sign in Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. You want to pay attention to the bumps. Hotend moves a mm or so and stops. Note that Y axis homes softly as expected and X axis takes too long to register, resulting in a rough home. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It has a distinct beak and the mouthline is curved down at rear. question or BUG] Sensorless homing sensitivity settings. If the head was in a position after a print such that Y endstop was encountered first there was no problem. StallGuard capable TMCxxxx stepper driver 2. Now homing the individual axes begins. A few prerequisites are needed to use sensorless homing: 1. After homing both axes are backed up a bit, by the same amount, to avoid grinding. @bthome, @CSHoffie, can you guys check with an oscilloscope or multimeter that the DIAG pin of your TMC2209 on the griding axis is not asserted when the caret hits the limit? Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip, [BUG] (TMC2208 hybrid_threshold not updating board). I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. If X homes before Y, then X grinds, and vice versa. This feature is so sensitive that it can actually take the place of traditional endstops.
