One at a time, go through your steps per unit If you have the high speed upgrade, it's different, but usually it's 20320 units per inch, -20320 if it's going the wrong direction. There's also a system setting for homing direction, but get your units right first. Then work on homing direction. Also, and because Techno's software is so buggy, quit the program after each setting change. One of the first things I'll be doing for one customer is removing Techno's software and installing my own, as it suits their needs better.
