following error goes to 32767 before motion is even commanded!

Well that was the standard setting on the stepper drive cards in the Primatics drive - but that WAS the problem.

I set the micro-steps as close as possible to the encoder steps and now it is all working properly.

I should have thought of that earlier - but at least I know I can wire things correctly 😉  Thanks for paying attention to this thread as I worked through it.

Of course I spoke too soon.

When I first changed the drive to 5,000 steps/rev to match the encoder steps and then ran the stage it worked.  Following error was below 100.

Shut things down change the rest of the drives - open MAX back up - following error is through the roof again!

Well I don't know why it worked the first time - but I double checked the encoder directions in MAX in open loop and they were opposite - so reversing A&B did the trick.  Now to shut down and restart everything to see if it sticks....  here's hoping.

I'm glad to hear that it was (hopefully) just one of the "standard" closed loop issues.
