Re: multiple start thread mach3
what's happening is, somehow the Z offset is ignored by mach3
i think mach3 tries to repeat the prior thread, regardless of the Z offset position
which means mach3 is somehow set to remember the prior position?
hy dovidu i am not sure, but you don't seem to be certain about how the controller behaves, so let's check it :
... cut a thread ( preferably simple, no custom infeed paterns, unless you are sure that your cnc syncs beween different infeed paterns )
... shift start_Z with +pitch/2, and recut only a few passes, with total doc = a few tens ( same rpm and same X_start as before )
if all ok, 2nd operation should deliver a small spiral ( small cut ), equidistant between the spirals of the 1st operation / kindly
