You may find that you will always need a test cut. There is no way the probe can account for tool deflection and cutting forces.

It looks like to me some calipers and radius gages would get that into CAD much faster.

Well, the fact that you get 10V without the VFD connect pretty much narrows it down to the VFD loading the analog out. You might try a signal isolator:

Acorn will use the steps per rev first before the revs per inch. So if you tell it to move a certain distance and you have these settings wrong it will default to the steps per rev that you have entered in the wizard... Almost there. Acorn operates in steps. People operate in inches or mm for those...

What do you have your motor steps set to on the drives? In the Wizard?

You need at least 3 motor revs per inch of travel for correct positioning, so you need add a belt drive between your motor and screw, or replace your screws with a smaller pitch.

Just setting the revs/inch to 3 will not work

Make sure your spindle motor wires are properly shielded. Separate the spindle wiring from control wires and if they have to cross, make sure it's at 90 degrees.

If the motor drives are not showing errors for list steps, then it is probably a noise issue. Try re-running your program with the spindle off.

You might have a look at parameter 1.

All Acorn schematics are here. Use the search function to narrow it down to your Leadshine drives:
