Re: [CAD_CAM_EDM_DRO] upgrade

So Jonathan,

You are using the Bandit motor drivers, and the original power supply for
the motors?

For a processor or controller you are using something like a parallel port
interface card?

So now you can program on your pc and run the bandit from that pc?

Are your motors Nema 42 size also? Are most BP stepper motors Nema 42 ?
Thats all I have seen but I only have seen a few.
