  • I have a 6 wire stepper with 12v 0.4A spec (PN 57BYGH207). When it is steps slow it seems to work fine. When stepping faster it just jitters. The Power supply I am using is 12v 1.5A. I have some smaller 4 wire steppers that seem to work fine 12v 0.48A (PN 1-19-4203). Am I missing something?

No public wish lists :(
