Has anyone successfully configured EMC2 to control D&M Computing 048-83970 stepper drives? They use UCN-4204B translators in two-phase drive mode and TIP122 transistors. Not much else other than diodes, resistors, and the wiring terminals on these boards. I've set the timing variables equal to the translator data sheet and have moved the micro-stepping variable from 0.1-32. I can get all three axes to jog in the 0.3-0.6 micro-stepping range, but they skip steps while jogging in test mode. Any help would be appreciated.

Thanks!

Did you try and lower your acceleration and speed down?

Also you might try and give more time for step and direction.
