Multiple problems:
Having cooled off the shop a bit the limits violation seems to have

what later in the day brings. BTW the limit violations were
consistent between axis and tklinuxcnc.
Multiple passes thru a small routine show progressive x offset with
each iteration. :-(
Dial indicator on X is clean in one direction but not the other which
usually indicates a broken
coupler to the encoder. I'll have to tear into the housing to verify
that. Shift is about a cm for
each pass of a pocketing routine. Same shift pattern as another
routine to inlet a tang on a stock.
Well, could be a marginal encoder that is reporting more counts in one
direction than the other.
That COULD be affected by heat. Or, the encoder counter could be
missing counts.

I've unmounted the encoder and the coupling was not broken so that
leaves connections/cabling or
a failed encoder. This is the first summer with this cpu. The old Duron
1200 would go on strike when
the shop got too warm.
Much more to verify .........
