@uami The important thing is that you match whatever you use in your slicer, with your configuration. This will "tell" the Duet board how to interpret extruder moves. Relative is generally best, not least because the firmware has to internally convert absolute values to relative when doing a G1 Xn Yn En move. So if you have set your slicer to output relative extruder moves, then use M83 in your config.g. If for some reason you prefer to use absolute extrusion moves, then set the slicer accordingly and use M82 in your config.g.

@uami That's a pretty extreme setup you have:
15360 steps/mm for the extruder but only 1100mA. It seems to be a highly geared small stepper?
Above all that, a nozzle with ~0.1mm diameter (0.15 extrusion width)

I guess you've checked already if all these parameters are correct.
Maybe you have some settings or startup-code in your slicer that messes them up?

The only F-parameter I see in the gcode snippet is F900 = 15mm/s
Maybe that's too fast for the extruder?
