Motor stall detection with Duet3 expansion board

DanielPetrea

HI,
I'm using a duet3 6hc with duet3 expansion board. I need to use the motor stall detection with axis that are on the expansion board, but don't work.

T0
G92 U0
M574 U1 S3
M913 U70
M400
M915 U S4 F0
G1 H1 U-50 F3000

I tried this macro with the U axis connected to the mainboard and works, but when i connect the U axis on the duet expansion board this feature don't work, the motor stall are not detected.

Thanks,

deckingman

@DanielPetrea You're right - it doesn't work. That is to say, it isn't supported https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations

Quote from that link "Stalls of expansion board motors are not yet reported and cannot be used for homing".

I asked this a while back. See (https://forum.duet3d.com/topic/18095/sensorless-homing-on-expansion-board).

TLDR: Scheduled for RRF3.3
