Do you know if the motor pins are correct? (1a 2b 2a 1b) I had to use 1a 1b 2a 2b to get it working but my stepper gear only works at low speed (30). Could you let me know if you got everything working correctly?

@Motalw hopefully you have got it working by now, but the manual incorrectly shows ABAB. Steppers should be wired AABB to work correctly.

@Xonman @Motalw I had the same issue and wiring AABB worked for me.

Hi @kullwarrior - is that diagram correct for the v1.1? the stepper 1A 1B 2A 2B doesn't match the manual which was also updated for v1.1 last week (about the same time as your post) its 1B 2B 1A 1B - and this is the same as the ERCF v2 manual. I'm having troubles getting NEMA17 steppers to work properly using the latter (and also finding the proper pinouts for the trianglelabs TL-42BYGH20 which they're suppling in their ercf v2 kit). thanks Wayne.

Those 2 pins are different from the v1.0 and the v1.1, only figured it out because I happened to of bought one of each by accident. It is in the manual. One page shows the v1.0 and the next shows the pinout for the v1.1. Very easy to over look
