When trying to home a CoreXY via sensorless homing you need to drive the axis individually as both XY motors are used for moving the carriage. So you first need to home one axis an "listen" for either motor stalling. Then you need to move the other one and also wait until either motor stalls. (Ideally they should stall at the same time) So the QUICK_HOME option should be disabled. The print headby Camaro - Firmware - Marlin
Hi, I got the same problem since I updated Marlin about a week ago. Before sensorless homing worked perfectly. G28 X : works perfectly G28 Y : works perfectly G28 XY : does not work I also have a CoreXY printer and am homing X and Y independently. (first X then Y). When doing a G28 XY the printer homes X and than tries to home Y, but stops immediately as if it would have hit the end already. Itby Camaro - Firmware - Marlin
Hi again, my mistake. I didn't know that the backslashes at the end of each line are needed. My code missed the backslash behind TMC_ADV () { \ I added them and removed all empty lines. hysteresis_start also needs to be changed to hstrt(..) and hysteresis_low to hend(..). Now compiling works without an error. As for my second question: How can I find the correct values I need to set that theyby Camaro - Firmware - Marlin
Hello, I have a similar problem. I am also using the TMC2130 in sensorless mode on my X and Y axis. My Z axis is driven by them as well, but i us an extra endstop for this axis. I experienced some shifted layers with these drivers in StealthChop mode and speeds above 45mm/s, but with below that they worked quiet well an were inaudible. But as I'd like to get the most out of my printer and wouldby Camaro - Firmware - Marlin
