Sorry for the misfortune you had. They need to rerate the board to a lower voltage. Maybe you can run 36v but with only a certain size or design. Can a motor design or size affect the amps/volt combo or is it my lack of understanding electric properties. It sounds like they did work fine at lower voltage. Thanks for the good advice.
It sounds like maybe my nema17's at 18v aren't as big a joke as I thought. I was looking for a 4axis at a good price. Even hobby circut were more. Hopefully it will work fine for me. I planed on using four of them for hot wire machine. I wonder what motor/volt work best with these. I thought I could upgrade to a bigger motors later. Maybe not. At least not too much bigger
The board that Tony promotes has a different looking design. Anyone using his? Anyone using his. it looks different than this hyu board. They make commercial cnc machines so it would be nice to find out what they rate the machine they go into.
