I think I now have the confidence to try replacing the E1 driver on my 1.02 board if I ever take it out of the DLP printer.

there is no thermal pad under the tmc2660 but there are a lot more ground planes over there. preheating the board makes life a lot easier.

You're a wizard. That solved everything. It is now flying as I would expect it to!

Thank you so much for the second set of eyes.

Wizards, one and all. I knew I had to be missing something. I put a little pat of SuperLube on each balljoint and ran the test again.

I still have a little bit of tweaking but that's very, very close to the mean error of .009mm

Thank you!
