Title: cnc4pc.com probe + mach 3 plugin
Post by: diyengineer on June 13, 2012, 10:20:27 PM

So the probe works, and when triggered the digitize light comes on.

What i can't figure out is how to work the digitize wizard.

It gives a Z- command but instead of probing down to my table it goes up and trips my upper limit switch.

can someone give me a crash coursE?

IF a Z- move goes UP you have the z axis backwards to normal convention.

Just a thought,  (;-) TP

What is the standard when it comes to g code? If you wanted to lower the spindle to the table would that be a positive z command or negative.

Negative IF zero is above the table top.

Thank you BR549. I believe that is how i have it setup, but i just switched screen sets so that may have been lost in the settings? I will confirm.
