Hello CNC pro's, i come before you again with another question.

I'm working on a DIY cnc machine currently and have gotten all of electrical stuff working except for a permanent power supply. I can drive a single stepper motor with a cheep variable power supply I use for prototyping, but i need to find a permanent power supply. the driver boards I'm using call for 20-50 vdc and I'd like to power three at a time. I'm only using NEMA 17 bi-polar stepper motors now but I would like the ability to upgrade to NEMA 23's eventually. Does anybody know a good place to buy motors for this application or maybe good learning resources online. I'm not an electrical engineer but I have a good understanding of basic electrical circuits.

There are indications that the JMC-2M542 driver may be the same as the Keling KL-5042.

A good starting point may be to look at the 3-axis kit that Keling sells that incorporates a KL-5042 along with a suitable 387 oz-in NEMA23 stepper motor for each axis, plus a 36-volt power supply, a breakout board, and a 5-volt power supply.

See Page Title for a description of the package, and NEMA 23 CNC Router Stepper Motor kit for pricing (item 9).
