Powering 3 45Ncm Nema 17 Stepper Motor 2A 4-wire (not CNC)

[Clive S]

AHA ! Clive awesome.. just seen the picture on the listing ..thanks mate as always .. going to go with that setup and play around :)

They do get an unfair bad press but if you keep within the current rating they are fine and at that price you can always buy a spare.

Remember not to disconnect a motor when powered up as this will let the magic smoke out.

Good luck

My little play kit is an arduino with a TB6560 to drive a stepper and a couple of relays. Project 1 is the Air/Spray/Mist cooler idea and project 2 is a spindle cooler with a small liquid volume closed circuit with a pump and radiator, controlled by a thermocouple in or on the spindle. This would also display the spindle temperature.

Here's a photo of the bits -
