I found that on here (https://forum.duet3d.com/topic/4568/sensorless-homing-for-deltas/5)

Hi,

What firmware version are you using?

Possibly M915 is not allowed with G28. The example test macro look like this:

;''' Sensorless Homing test file for RepRapFirmware on Kossel'''
M400 ; make sure everything has stopped before we make changes
M574 X2 Y2 Z2 S3 ; set endstops to use motor stall
M913 X50 Y50 Z50 ; reduce motor current to 50% to prevent belts slipping
G91 ; use relative positioning
G1 S1 X700 Y700 Z700 F4000 ; move all carriages up 700mm, stopping at the endstops
G1 Z-5 F2000 ; down a few mm so that we can centre the head
G90 ; back to absolute positioning
M400 ; make sure everything has stopped before we reset the motor currents
M913 X100 Y100 Z100 ; motor currents back to normal
G1 X0 Y0 F2000 ; centre the head and set a reasonable feed rate
M574 X2 Y2 Z2 S1 ; set endstops back to normal so that homedelta.g works

Which Duet are you using? The stepper drivers on the Maestro do not support stall detection. The ones on the Duet WiFi/Ethernet do.
