"Divide and conquer".
Comment out everything except one single axis and try until you find it.

well we sorta already did that. there is no setting that doesnt either flicker the drives or slam the axis. like it does't respect search or latch vel at all.

that has to be a clue. something ELSE is making it home. maybe it IS doing internal drive homing?

ok, so

machine off:
controlword = 4
statusword = 2672
opmode = 8

machine on:
15
6711
8

press home all and instant crash and fault

saw something about forcing opmode 8, however this changes nothing. still full speed into the end stops.

another suggestion is to just inhibit motion, but that seems not right either. Need to find out WHY it is moving.

so if i home and crash, is there something in the controlword and statusword i should see? it happens in a few ms.

Sounds like you are set for internal homing. If you want to do Linuxcnc homing, use generic pin types which you can set in your XML and don't load a homemod. This still works well.

Nothing seems to change when i home other than the joint error from the crash (i've blocked the axis). So maybe its not the drive homing after all.
still makes zero sense.
