Since no one has commented I updated to todays build, no help there.
lcnc refuses to move the machine by my code more than once per startup.
It sounds like the code leaves a parameter in a state that causes the
code to skip.
If it isn't error-ing then it is probably running to completion, but
not doing what you expect.
Try running through it in single-block mode.
I got tired of looking at all the screaming qt was doing trying to get
my camera to work, so I commented it out. Another and2 fixed the false
atspeed indicator saying its at speed when stopped. But what I set for
MIN_VELOCITY in the spindle_0 section of the ini has no effect. I still
have to click the + button to start the spindle at about 105 revs. So
now its warmed up, I'll go play.

More of the same, might be a little more stable w/o all the qt
screaming.
It will Single Step to the end of the first
hole while I fine tune some of the presets for the first hole, And as
the center of x or y is found. I mam updating the 3 vars that the hole
finder routine uses to recenter before starting the next measurement.
But my run once per restart of linuxcnc continues. It will not restart
the spindle on the 2nd try. This "first move" is in the o sub.
The s<_searck_revs> command is a few lines prior to the M4, works the
first time every time, very occasionally works 2nd time.
When I know it should have spun up the spindle to around 1000 revs to
find the linear rails top, the spindle hasn't turned and the atspd led
is still red. No debug statements elsewhere in the code ever exec.
No response at all to the step button but the stop button works fine.
All indications are that atspeed is the culprit. I can debug the
#<_search_revs> var, and it reads just fine. But an M4 on the mdi line
does zip.
I sure could use a clue. Latest, probably messy code attached.
Thanks Andy. Take care & stay well.
Cheers, Gene Heskett, CET.
