Good day, I am the new one and come from Germany. I have modified my Anycubic Kobra Max and now use the Manta M5P board and the TMC2209 from Biqu. I have the following problem. I can control the individual motors, but during homing, the following message always appears: No trigger on y after. What is strange is that the Y-axis, that is, the heated bed, can be homed without any problems, only the print head, i.e., the X-axis cannot be homed and triggers this error. The head touches the end stop switch, moves away briefly, then triggers the switch again and remains in this position. Unfortunately, I am at my wit’s end, I have checked all the wiring, I have checked the limit switches, but I don’t know anymore. I hope you can help me. Thank you very much.

Hello @lil-ac

Actually, that is the homing sequence.

Have you checked the wiring?
Maybe swapped the X/Y endstop plugs one the board?

Yes, I have, and also a TMC2022 that apparently wasn’t working properly. I replaced it, and now it works. However, I’m having an issue with the Biqu MicroProbe v2. It extends the probe and moves the Z axis up slightly, retracts the probe, and then reports the error: “Endstop Z still triggered after retract.” Also, the movement of these two motors, Z and Z1, is very loud compared to the other motors.
