Re: Unknown Spindle Speed for Lathe (for eternity)?

Re: Acorn Losing Steps

The fact that it makes the first part ok and is then offset for the next implies that something is happening during the rapid moves back to the home position. The fact that you had been running for two plus years prior to this without problems implies that something mechanical has happened. Assuming...

Re: Home to limit switches.

Whenever you hard code a value in a program, I explicitly call out G20 or G21.

Re: Acorn Losing Steps

My guess is something mechanical. Increased drag, loose couplings, etc.

Re: Home to limit switches.

Go ahead and change the machine units to inches. It will convert everything over automatically. There have been issues in the past with having display and machine units different. It seems like every other job I do switched to the opposite of what my machine is set to. I just switch them both to the...

Re: ENA1

You could try swapping two drives and see if the problem follows the drive.
