As long as I have the option disabled, it seems to work fine. You can try saving EEPROM with M500 and see if the LCD is properly initiated after that. The top side of the slug is covered in small wart like bumps (tubercles). * Higher values make the system LESS sensitive. When I disabled quick home, there were still instances of the behaviour at other times (sorry I can't be more specific), so the issue isn't solved by homing in sequence, but it is masked in the usual pre-print G28. I have some issues with Sensorless Homing again as well. I'll keep the screwdriver at the ready for removing my endstops whenever someone clever fixes this. Configs: Ender-3 - SKR 1.3 - Marlin-bugfix-2.0.x - 940ff8e - 5-11-19.zip. move marlin to the root of a drive and rename it M delete unused HALS (don' t removed shared!) oki, if you have the same issue we can reopen and even slam the confirmed label on it. I remember thinking, cool, faster XY homing. @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? If you wanna get rid of this problem, give out the following commands: (For example { 5, 7, 2 }) Then try quick homing several times. Now homing the individual axes begins. 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). 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. First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. So we need to copy the file into our new marlin. 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. 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. I have this sneaky feeling that there is something nasty lurking in the endstops.cpp code that is disabling the X endstop, when QUICK_HOME is in effect, and whilst I took a look through the code it quickly exceeded my capabilities in C++ and my will to live. Even increased the sensitivity on the X until it was false triggering. It has a distinct beak and the mouthline is curved down at rear. Maybe this is related to #14464 ? issue, please let us know how you solved it. I don't currently use my delta, and my current printer has A4988 steppers, so I can't check. Y axis still homes twice as expected - is that normal? The impossibility of safe automatic sensorless homing. 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. * X, Y, and Z homing will always be done in spreadCycle mode. It failed 20 tests on 800ma and failed 0 on 200ma. Using auto home, X homes using sensorless homing, Y homes using sensorless homing, as it proceeds to the bed center to home Z it grinds and never makes it to center. Completely off topic (kind of), but the X axis now homes 3 times, twice as normal and then after the second home, a bigger back off and a 3rd home is performed. The firmware will continue to try to reach and hold the temperature in the background. I am also running an SKR 1.3 with genuine 5160 Watterott drivers in SPI/sensorless homing mode on an Ender-3 with the bugfix-2.0.x commit (940ff8e) from yesterday and the a613bca commit from 5/10/19. This issue has been automatically locked since there has not been any recent activity after it was closed. * X/Y_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. Thanks for your suggestion but this isn't related. Did I miss something in configuration process ? Have a question about this project? Please add a reply if you want to keep this issue active, otherwise it will be automatically closed within 7 days. MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. M502 --> resetting the values to the hardcoded params If you'd like me to diagnose further, just tell me what I can test, I have no idea where to start. However for X and Y, bump homing makes things a lot more stable so I have bump enabled for X/Y and disabled for Z. Tweaking the sensitivity is actually quite easy. Lack of Activity 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. Pastebin.com is the number one paste tool since 2002. No update from me. Hotend moves a mm or so and stops. For the other axis, where the endstop was not already triggered a first move is initialized, what will grind because the possible way to move was smaller then SOME_WAY.

Well I just replaced the speed back to 20 * 60, and not only did it fix the problem, but I was also able to significantly drop the TMC Bump Sensitivity value (X & Y from 65 back to 25). Set a new target heated bed temperature and continue without waiting. Have a question about this project? The TMC2208 problem has been present ever since. 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. If I revert back to the 15357af commit from 5/3/19, the values are populated in the TMC drivers menu. * * X/Y/Z_HOMING_SENSITIVITY is used for tuning the trigger sensitivity. With my latest compile I re-enabled quick homing to see if I could narrow it down using different configs, but no luck so far.
