It really shouldn't need a shutdown and restart.
It did Andy, then I found a note about subroutines in 11.7.4 that is a
bit confusing. First, one named sub can't call another, but then it says
it can call itself. So I broke it up into single pieces w/o any nesting
in the main loop, but haven't gone out to test it yet as the weather is
a bit damp. Probably more typu's to fix when I do. What I'm tryimg to do
is locate every 3rd bolthole in a 540mm long 9mm wide linear bearing
which is clamped in place by printed jigs on a 560mm long cf tube
measureing 20x20, held in good y alignment by two printed vises with
opposing movable jaws so it dialed within a thou of straight with the
mills table. First I go into the counterbore of the screw hole, locate
that with a spinning probe, then if that works center it and go in 4 or
5mm to get inside the 3mm hole, find that and record xyz in the array.
Find the center of the 3mm hole and re-record that. then increment the x
in both arrays by 60mm and find that hole, wash rinse repeat for 8
holes. If I can do that, then I change the probe for a 3mm sc mill and
drill the holes in the cf for 3mm bolts. Then turn it over in the vises
and do it again since I put another rail on the bottom of the cf tube.
The printer I'm rebuilding, a tronxy400pro that never worked had all
that flying weight made out of steel and solid alu and is going to lose
at least half a pound of flying weight the xy motors won't have to throw
around...The plain steppers have also been replaced with hanpose
stepper/servos running on 3x the normal driver voltage, with optical
encoders feeding the matching drivers. Turning a 40mm/second printer
into a 400mm/second+ printer. I hope.
To better describe it, if the code is edited and reloaded after an
error, all the stuff before the first move that has debugging statements
in it, executes normally but it will not execute past the first machine
move on the subsequent try until stopped and restarted, rehomed, and the
code reloaded. Weirdsville... Even w/o errors, it only works once.
Thanks Andy. Take care & stay well.
Cheers, Gene Heskett, CET.
