Control / Driver replacements

[m_c]

In that case, cheap BOB from eBay. Just search for CNC Breakout Board. Take your pick of any of the 5axis one that every man and their dog seem to be selling. Cheap and do the job.

Then select your choice of stepper drivers.
Assuming relatively small steppers (up to 5A), at the cheap end, TB6600 drivers.
Bit more expensive are the DM542 drives. Next up would be something like AM882's.

Only thing I can't remember, is if that board can handle spindle drives that are not isolated i.e. the typical basic KBIC/SCR drives used for DC spindle motors.

Thanks for your help with this.
