Can someone tell me why the first probe will not happen during run but will happen if I run as a single blk.

Why are you using F200 for a probe speed, I use about F20

You may be over running the Z axis velocity

i was just changing settings to see if it would change.
it was at 19. but when i run the whole code it runs 90 the the next line after g31 and then everything else runs fine
if i run it in steps every thing runs

what motion software are you using?

mach3 mach4????

what motion controller are you using?

probing (jogging and thc) are internal functions of the motion controller and are not a function of the cam software (once the code is there it is there to run) and is not a function of mach3 or mach4 as it is done within the motion controller....

try adding a delay before probing. (G4 P1.0) ... maybe the motion controller will take notice of g31...

Anyone??

Post by **robertspark** » Tue Apr 13, 2021 2:23 pm

what version of mach3 are you running?

it seems some of the older versions may have had a bug in them for this sort of behaviour.

Thats normally the one that is recommended for motion controllers (something broke in 066 for the smooth stepper anyway).

sorry I am out of ideas.

as I said, it seems you are using the right one from my experience. the right one is really the one that works.

you can try contacting the manufacturer of the motion controller for guidance as to the right version for the plugin and motion controller.

Probing is an internal function within the motion controller and is not something mach3 controls

sorry I have moved on from mach3 (too many glitches and bugs and always dependant on some black box firmware and hoping it works.... till you find it doesn't and can't fix or diagnose it yourself).
