step and dir pulse problem Mach3

[mrmacca]

This is typical of Chinese machines as they fit oddball motors which you probably won't find any info about. However, doesn't really matter too much because you will only have at best 36Vdc from the PSU so any drive with a 50Vdc max rating will work for you. Because you can't tell the motor current a little trial and error will be needed on the amps but this is no big deal as they will just run hot if too high and stall easily if too low.

These will work fine for what you need and will work miles better than what you had before. But before buying it's worth checking the voltage coming from the PSU
