M915 Not Working!
-
I turned on M929 for logging and setup the M915 command for stall detection but its not doing anything when the motors stalls. I am using TMC2660 motor drivers and have tried setting the sensitivity to max even but still no response at all when the motor stalls. There is no record of any logging when the motor stalls so I am confused as to what to do in order to fix this.

Have you followed this guide? https://duet3d.dozuki.com/Wiki/Stall_detection_and_sensorless_homing
If you can give some more information about your printer, eg CoreXY/Cartesian, motors, voltage, and post your config.g, that should go some way to help diagnose the problem. You haven't given us much to go on!Ian

Yes I've followed that guide, I believe that printer i CoreXY, the motors I use are 23HM22-2804S Stepper Motors that are powered with a 24V input and are rated to run at 2.8 Amps but I run them around 1 Amp. Here is the config.g file, the firmware currently running on the printer is version 2.03

How have you tested this? Logging stalls only occurs during printing from SD card, not when you send movement commands manually.

Is it possible to change the firmware to allow it to monitor the stall detection under manual moves as well as regular moves.
