I bought a controller/motor/driver/2xPower supplies set from ebay last week.. it's still on its way but I have realised that the kit I chose didn't have the power supplies in. Annoying! I thought it was a bargain :) It's too late to cancel so I need to sort out the power supply.

The kit I intended to get came with:

  • 4 pcs Nema 23 stepper motor with 425 oz.in 23HS9442
  • 4 pcs stepper motor driver DM542A, peak 4.2A, 128 micsteps, replacing M542
  • 2 pcs Power supply 350Watts (36VDC/9.7A)
  • 1 pc Breakout board & 1 pc Parallel cable


Does anyone have any recommendation for what I should get? Just replace with the same or would I benefit from a higher powered unit - or 2 higher powered units even?

Budget end of the spectrum by the way :)
