Stepper Motor Controller

Introduction

• Nema 23 motors are about 6x6x8 cm size - and require _______ amps for driving.
  • Xylotex says body length is 3"

Options

• 5 axis version of controller brain (minus power handling) - can this be used with any power-handling system? - [1]
• An up to .75A brawn module from Sparkfun - [2]
  • Any advantage cf. open source RepRap stepper controllers?
  • This does offer USB connection, and is open source - [3]
• 3 axis, 3A kit on eBay, $200 - [4]
• CNC Stepper Motor Controller at [5].

Turnkey Systems

• 2-axis, 4A, 24V system - [6]

Brainstorming

Power supply

What if we used power supplies for PCs? They're pretty high current and they can be placed in series for 12 volt, 24 volt, 36 volt, etc, systems. They've got 5 volt taps I believe as well to run the microcontroller off of. They're ubiquitous and either free or cheap. Jason 00:46, 23 May 2011 (PDT)
