The shift in G55 didn't disappear every loop through a pocket shifted

Is the machine absolute position shifting? ie, if you set your display to
"machine coordinates" and jog to the home position, does it show the right
values?
I can't see how even a dodgy encoder can move the soft limits. (which seems
to be the reported problem)
How do you home? Are you confusing homing with touching-off?
As I said in a previous post. I posted too many questions in one post.
Keeping them sorted in replies
is a problem. The encoder is one problem and the out of limits is
another. Cooling off the shop
seems to have cured the limits problem ... for now.
I'm homing in the easiest manner possible; Move all axes to machine
(mechanical) zero and click mouse.
Not that it makes any real difference but my 0,0,0 (G54) is lower left
for X,Y and spindle all the way up, Some people home to mechanical
center of bed; and I've actually heard of
people homing to upper right corner. I just don't think that way.
How do you home? Are you confusing homing with touching-off?
I hope not! Home to G54. Touch off for G55...59.3.
As for the thermal problem: right now I'm blowing cool air ( 20 C ) into
the shop.
