yes, I'm familiar with the machsupport forum thread, but nobody has addressed the new design. I am pretty sure the VFD at the link I provided matches my VFD. It actually looks easier than the older design. Of course, I could be wrong.

I really want to use my lathe today, or I would look at it. Unfortunately, digikey doesn't have the IGBT, but mouser has both parts. The only trick looks to be soldering the optocoulpler. Okay, soldering the IGBT doesn't look that easy either.

I was thinking about building an external braking module, but if this works, I'm not going to do it. My lathe really needs external braking, it has huge inertia. It has a monster of a gearbox.
