Bugs that may have existed in 1.1.8 aren't really relevant anymore. The humback whale is relatively robust rorqual and can reach up to 16 m in length.

I'm running the SKR1.4 Turbo + TMC2209 V1.2 on the latest Marlin bugfix 2.0.x, and having the same issue. I use the waterott TMC2130s. As far as I've understood, the menu “Configuration/Advanced settings/TMC drivers/Sensorless homing” is intended to set Stallguard sensitivity, thus homing bump sensitivity. @boelle Yes, unfortunately so - I update to the latest bugfix branch almost every week in hopes that it's somehow magically solves, but alas... still the same :(. 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. The impossibility of safe automatic sensorless homing. Michel. M500 --> store it. I get quite a decent amount of false positives and setting the Bump Sensitivity to a higher value doesn't affect anything but i can't really explain why the issue occurs.

[BUG] Harsh X axis sensorless homing on TMC2209. al., today Marlin drives most of the world's 3D printers. Hi. As soon as I home X and Y together (for e.g, with G28 XY), I get the grinding issue (about 90% of the time). I never said or assumed you're a company and work for profit? If I revert back to the 15357af commit from 5/3/19, the values are populated in the TMC drivers menu. After homing both axes are backed up a bit, by the same amount, to avoid grinding. Most 3D printer electronics include a little bit of storage (512K, 3K, or more) called EEPROM (Electrically Erasable Programmable Read-Only Memory) that persists when the power is off. Set a new target heated bed temperature and continue without waiting. Sensorless homing works fine and running M122 , returns the correct values from EEPROM for all three of these commits. In the end, sensorless homing in working fine (only tested on X only yet) with values defined in config_adv.h, but it’s very confusing behavior. #18563. The lower jaw has a single pair of teeth (exposed only in adult males). i'm having the same issue with TMC 2209. X axis seems to not register the endstop immediately and results in a split second of grinding sound. If that diagonal hits the corner nearly perfect always one endstop hits first and the move stops. I don't think this has lacked activity. I just hope someone be cleverer than myself can pin this down. What is your endstop status after homing? Confirming this is an issue for me as well. A way to fix could be, to back up both axes (that with the not hit endstop could de enough (if easy detectable)) at least SOME_WAY after the diagonal move and before the homing of the individual axes. * * X/Y/Z_STALL_SENSITIVITY I'll try to debug the IMPROVE_HOMING_RELIABILITY feature later and post updates. So we need to copy the file into our new marlin. [Stupid (?) What's interesting is that, when I enable IMPROVE_HOMING_RELIABILITY, the thresholds seem to change. 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). SKR 1.4 Turbo + TMC2209. I remember thinking, cool, faster XY homing. DIAG1/DIAG pin of TMCxxxx connected to the MCU I don't plan to switch back to sensorless until I see any sort of update. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks. https://github.com/drewzh/Marlin/blob/bugfix-2.0.x/Marlin/Configuration_adv.h. More like request to look at that. Disabling QUICK_HOME solved the problem and it mattered not, which Axis homed first. If you'd like me to diagnose further, just tell me what I can test, I have no idea where to start. Description: M914 (TMC Bump Sensitivity) returns incorrect values when negative. to your account, Bonjour à tous, The forehead rises at a shallow angle and has a slight bump. Homing Y before X doesn't seem to matter. Without the feature, M914 X100 Y128 seems to work really well. G28 and X grinds (Y does not), G28 X = No grind. issue, please let us know how you solved it. A few things got in the way :) I've just re-flashed with latest bugfix-2.0.x today and checked that IMPROVE_HOMING_RELIABILITY is switched off. * Higher values make the system LESS sensitive. Most recent Marlin 2.x bugfix G28 XY. Hotend moves a mm or so and stops. MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. Does the behaviour change after powering the printer off and on again? So the end position is warranted to be near the diagonal to the corner. oki, if you have the same issue we can reopen and even slam the confirmed label on it. Now onto the latest GCode as of Marlin 2.0.5 G0-G1: Linear Move Start high, for example M914 X192 Y192 and then decrease the value until it only triggers when bumping the end of the rails. I found that enabling CODEPENDENT_XY_HOMING and as a side effect, disabling QUICK_HOME, forces the axis to be homed in sequence rather at the same time, resulting in a perfectly quiet homing sequence. With the feature enabled, same settings make homing too sensitive. The humpback whale Megaptera novaeangliae is a baleen whale and can be recognised as such by the plates of baleen (rather than teeth) suspended from the upper jaw and the two blowholes on the upper body. * X/Y_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. privacy statement. Actual behavior: Axis don't move, X/Y endstops are triggered. StallGuard capable TMCxxxx stepper driver 2. We’ll occasionally send you account related emails. By clicking “Sign up for GitHub”, you agree to our terms of service and Homing individually seems to stop the behaviour, i.e I can issue constant G28 X commands and not have a single instance of the grinding behaviour. Sowerby's beaked whale is a small beaked whale that can reach up to 5.5 m in length. I also noticed that homing a single axis, also makes the opposite axis 'twitch' after being homed - not sure if this is expected or a previously seen behaviour? Especially the 'Additional difficulties with Quick- and DELTA- Homing.' But I think I found the solution, at least for my case. The sensorless homing works - but it's rough as hell. One more thing that I realized is that with Z, you don’t really want bump homing so Marlin documentation is spot-on about that. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. I remember looking at the changes in Git from my previous code to current, and seeing a line change in 'configuration.h': (no CoreXY but Prusa-Style-Printer) Right now i am using commit cbcb284 and didn't changed anything on my setup so far. For the E3D Toolchanger (beta) we have —running RepRapFirmware— we had the same problem, and finally just gave up on combined homing of XY. what else you've tried in the meantime, and possibly this issue will be The X axis hits the endstop abruptly, whilst the Y endstop is very soft. Jumpers on the SKR are closed any I ensured that there is an electrical connection between the DIAG pin and the endstop. I encountered it on my hypercube running Marlin 1.1.8 on a MKR Gen L v1.0 with DRV8825 drivers... the X axis endstop appeared to be disabled and the print head attempted to bury itself in the Y axis carriage, where it juddered until it timed out. That's the case for me. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. When using SENSORLESS_HOMING with TMC2209 drivers. I see they changed the main boot-up order of things in there @teemuatlut if that means anything ? * Lower value make the system MORE sensitive. This issue has been automatically locked since there has not been any recent activity after it was closed. Right ? Set a high value for bump sensitivity and fine tune it down. I do not know if this is related, but it is possible that sensorless homing issues may be caused by TMCStepper 0.7.0. Things seem to be much smoother now - though I haven't checked whether IMPROVE_HOMING_RELIABILITY actually changed the behaviour, but after this current print is finished I'll re-enable and give it another check.
