This gcode, when I can get it to run, finda all 8 holes just fine. And
now it will not run twice, refusing to go past the first move command on
the 2nd try after a full restart, and rehome.. With no reported errors
on the first run..
This is the current copy attached. nuke any others you might have before
saving it, I won't touch till someone tells me to.
Thanks all. Take care & stay well.
Cheers, Gene Heskett, CET.
