Which Stratasys model? 1200, 768, uprint, etc? I have a 1200es BST I've been mulling over retrofiting using the info below.

It's a Fortus 250MC, about 9 years old. It's been a workhorse for us and produced prints almost every day for all that time, so it certainly doesn't owe anyone anything, but the motion system is so nice I want it to live again.

Check out these posts by @Archeantus , they were able to do a fully reversible retrofit on a uprint, using the original tool head parts, steppers, etc, bypassing the original Stratasys electornics boards.

I've been searching through here (before posting, as I'm sure I'm not the first person to try this), but I think it's our PDB that has blown. Hard to be sure as there is a lot going on in there. The 5V PSU wasn't working, so I replaced that, but not sure if it was a symptom or the problem, as now the SBC in there continually beeps.

Well changing the motor direction is certainly doable. It's the "S" parameter in M569. So you could use M569 Pn S0 in one tool change macro (say tpost0.g), and M569 Pn S1 in the other tool change macro (say tpost1.g).

Rebuilding the head at the moment to take Revo hot ends, but will try that - thank you.

Please update the firmware and DSF. There were some fixes in RC12.
