Hey, i dont know why, i cant create a new post, sadly. So im trying my luck here.
So, ive been trying to set up sensorless homing and am completely unable to.
My setup :
Duet 3 Mini 5+
E3D High Torque Motors
I've followed the official guide step by step and tried many parameters. I believe i was on 3.2 firmware, which i now updated to the latest which is like 3.3beta2
I had it working according to a guide on this forum where it was setup like this :
M400 M913 Y75 M915 Y S-15 R0 F0 H200 M569 P0.0 V0 G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H2 Y20 F6000 G1 H1 Y-415 F4000 ; move quickly to X axis endstop and stop there (first pass) ;G1 H2 X10 F6000 ; go back a few mm ;G1 H1 X-415 F2000 ; move slowly to X axis endstop once more (second pass) G1 H2 Z-5 F6000 ; lower Z again G90 ; absolute positioning M913 Y100
Sensorless homing worked at that point, but i had a issue where in stealthchop the motors made a horrible noise, much louder than in spreadcycle for whatever reason.
I than turned the board off, plugged in a second motor (had just the X motor plugged in atm) and that issue went away, but here i go with the same issue as before - when homing, my motor reaches the "end of the axis" and starts skipping steps without rotating the shaft, just vibrates on one spot.
Thats even if the load is taken off, it gets stuck in this state. I know my description is pretty hektic but i have honestly no idea of why this is happening... Anyone have any ideas ? Thank you !
