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.

...and to clarify, you just need one of those pulse generator modules, which can drive three of the cheap stepper drivers. That way, all three motors will run at the same speed.

Well the project I'm working on is to start with an analogue mechanical machine. I have a couple of arduino + PWM boards and a robotics setup for RasPi.. ATM want to KISS the project. But if I can get it off the ground then I'll definitely be asking you for more advice on adding a more accurate control system, especially to steadily increase the RPM's. Heats not a problem as it has a water dripper for cooling. I'll use the spare DC motor controller and attach it to a small 3 inch fan to cool the other controllers.
