Okay ger, I set zone to 6 and 2% and no difference. The accel is at 17 for the X. Maybe I just need to find a compromise on the velocity (?)
EDIT: Well I'm completely out of ideas now, the only way I can get it to work at all is to slow the velocity down to barely a crawl and up the accel to a point that it's too high. I've changed every setting I can find except the steps per inch. I guess I'll have to live without the slow zone on the X for now unless you guys have any other ideas.
Thanks again for trying to help !
