Re: Taig CNC mill .......and Emco

Chris,

No clue on the FB100 mills. It the plugs are compatible, I'd suggest
swapping motors, drivers, etc. BUT... if they are blowing the fets, not
a good idea! 5 phase vextra motors? NEMA 23's? I know what I'D DO,
goto to Camtronics and set them up for bipolar steppers and new
drivers. And probably opt for CNCpro.

The "damp environment" is a little scary, corrosion on connectors? rust
on ways??

P.S. What does an FB100 look like? Are they still available??
