Emco PC Turn 55 retrofit

Got myself a new toy last week. Picked up an Emco pc turn 55 with 8 position turret for 425 bucks. No controller, so swapped the ac95 board with a mesa 7i76ed, interfaced with the 3 phasen sm karte with an idc16 ribbon cable breakout board and got the motors to move pretty easily. Did the vfd hookup 2 nights ago. Gotta tweak stuff in, but I'm working on getting everything to work first, then I'll go back and tune it up. Next steps are to interface the spindle encoder and tackle the turret indexing. Pulled about a mile of extra wire out of the thing that I'll use to reconnect the safety switches and whatnot, because who doesn't like safety switches?

Sweet! I always wanted one of those myself.

I wanted a lathe for a long time. I would've preferred a larger machine, but this is a perfect start. Got it for $425usd. It was on Facebook marketplace for 800

Just got one myself, still ferreting around i would like to keep the drivers and spindle card , not the same as your though ,
best of luck with the project.

Which one did you get? There are a few versions. The pc turn 50 and 55 had two variations of stepper motor and drive setup - the 3 phase and 5 phase versions were totally different and the 50 had an emco proprietary spindle drive, where the 55 had a Lenze 8200. There was also the concept turn series, which was the same machine with different internals. I have the wiring documentation for the two versions of pc turn 55 (v00 and v01) if you'd like them.

If it's a concept, email Michael at emco. He's been spectacular with his support.

Yep , I would be delighted if you send on the manuals.
I saw a post here from a few years ago saying you can replace the AC95 card and drive the Y4A cards directly ,
