I've learned an important lesson along the way in creating my cnc router. "Heed the advice of others when it comes to power requirements."
I'm trying to get my steppers running and I don't thing my current power supply has the cajones to make it happen.
My 3 steppers are all 5.2 Volts per Phase, 1.4 Amps per Phase Unipolar 6 wire motors. Does that mean they require 2.8 amps total or am I just crazy?
Anyhow, what I've found it that my 12 PC power supply will run one motor just barely. When I connect up 2 motors to it, the supply just shuts down. I don't have any specs on the PS but I'm assuming it is rated at 200 watts.
If I were to order a power supply from MPJA that is rated for 24 Volts and 4.5 Amps, would that be enough to run my steppers?
I know I will also need some power resistors near 13 Ohms and 25 Watts.
