I'm in need of some serious help. Here's where I'm at.
I'm converting my little mill to cnc so I decided to go with the linistepper boards and 425 oz/in motors. I bought 4 of the linistepper boards as well as the beak out board which simplifies the connection of the four controllers to the printer port.
My problem is in finding a suitable power supply for this setup. I don't want to have an individual power supply for each of the driver boards, it just seems a bit ridiculous, but I can't find anything which seems suitable. I looked at my older hobby cnc controller and pictures of their new ones and it looks like it has a 24v transformer, going through a bridge rectifier, then into a large capacitor, and then into the driver board. A setup like this make much more sense to me, problem is that I'm not very knowledgeable about electronics and I could really really use some help in figuring out how I'm going to power these boards.
The motors I bought are NEMA 23 BIPOLAR STEPPER MOTOR 425 oz-in, 1/4” Diameter shaft with a flat
KL23H286-20-8B (Dual Shaft)
Specification Price: $49 Rated Current: 2.8A, Rated Voltage: 4.17V (in Bipolar Parallel)
Torque-Speed Curve
If you can help me please please do.
