Nope, not seen them.
Pro's: (in my opinion...)
  • Compact
  • Parallel port on driver, so less wiring
  • Coolant/switches etc are easy to wire


Cons:
  • A bit expensive, £190 at current exchange rate...could get 3 PM752 70v, 5.2A drivers from Zapp for that with money to spare.
  • Parallel port being on driver makes it more difficult if you want to use some pins for other things
  • 48v is reasonable, but more would be nice!
  • You can't run many big motors in parallel with only 3A.
  • Spindle output is a transistor, relay would be much more useful and in-keeping with the design.
