Update: I got sensorless homing working on all 3 axes.
Someone suggested adjusting stealthchop/spreadcycle like this: M569 P0.3 V40 D3 and it fixed one of the axes. For the Z axis with small motors I had to go back and forth with stall sensitivity and speed. Same for the remaining axis, basically trying random speeds and sensitivities until it worked. It took a while, but it worked eventually.
@fcwilt thanks for the help.
Still got that probing offset thing to fix, but that's tomorrow.
@droftarts indeed it was the E jerk. I had it set to 4. I assumed a high E acceleration would take care of it, but it seems not.
Edit: For clarification, I meant 4mm/s, which is 240mm/min.
Left: 1K acceleration without IS.
Center: 1K acceleration with IS.
Right: 3K acceleration with IS.
Printing at 150mm/s speed on a CoreXY about the size of a 400mm cube build volume.
Is this normal?
Coextrusion filament. Looks a bit like silk, very shiny, so artifacts are emphasized.
IS, PA, and jerk are already calibrated (at least to some extent).
Running RRF 3.5.0-rc.1. (I haven't tried any other version).
It looks better if I print much slower, but still, the prints look very bad to me. I'm hoping there's a way to improve the surface considerably.
