Stall Detection on Duet 2 WiFi and Duet 3 MB6HC

R006

Hi,

I’m using a Duet 2 WiFi board running RepRapFirmware 3.5.0-rc2. My setup includes six stepper motors: three on the Z-axis, two on the Y-axis, and one on the X-axis.
I’m trying to implement stall detection and would appreciate some guidance on where to start. I’ve followed the documentation at:
" https://docs.duet3d.com/en/User_manual/Connecting_hardware/Sensors_stall_detection "
I set up a table-top test, but stall detection doesn’t appear to be working as expected.
Here is my current configuration:

daemon.g

; Monitor for X stall
if move.axes[0].stalled
  M291 P"X Axis Stall Detected!" R"Warning" S1 T3
  M18 X ; Disable X motor

config.g

M569 P0 S1 D2         ; Configure driver 0 with stall detection enabled (mode D2)
M584 X0 Y1 Z2:3:4 E5  ; Axis mapping
M915 P0 S3 F0 R0      ; Stall detection for driver 0, sensitivity 3, no filtering, no action

Questions:

Is there anything incorrect or missing in this configuration?
Is there a recommended way to test stall detection in a controlled manner?
Should the daemon check be done differently in firmware 3.5.0?

Additionally, I want to implement stall detection on a Duet 3 MB6HC board. This setup uses:
-Three stepper motors for Z,
-Two servos for Y,
-One servo for X.
Can stall detection be applied in a similar way for servos, or would I need a different approach?

Any help would be greatly appreciated. @dc42 @Phaedrux

RepRapFirmware 3.5.0-rc2

The old unsupported 3.5 rc2 or the new in testing 3.6 rc2?
