Ive just bought a Boxford 250F that is running 3ph Fanuc OT system. I had planned to runn it off a converter but I understand that the OT system is quite old and cant handle large programmes.

I could reto fit with steppers but it seems crazy to loss the fanuc servos for steppers.

If I convert to 240v single phase I would like to retain the motors and run from linux cnc with mesa cards.

Ive seen The pico system and granite devices do a compatable drives but the pico is standalone and the GD is pricey.

Are there any other drives available or anyone done a similar project?
