I am using Mach3. I also have the 3 Axis Board.http://wiki.zentoolworks.com/index.php/ ... iver_Board
1. I am not sure what you mean by locked/enabled? Is that something in Mach3?
2. I have broken at least 10 bits already trying to find a solution to the issue... Double checked the spindle - no problems found - at least not mechanic?
All axis are working nicely actually - they are very smooth. I did try jogging around to see if it missed steps, but couldn't see anything. Was also holding the lead screw to try to feel something, but no...
I have cut out a whole piece of MDF to be sure the PCB was level. Did cut out 1.5 mm... worked like a charm. Actually only problems with the PCB for now cause the Z Axis goes up and down all the time... In the beginning (first minutes) it seems to be fine... later on it sinks deeper into the PCB till the bit breaks.. Shouldn't go lower than 0.9 mm...
Strangely I had the problem on the X axis before... Now it moved to the Z.
Can it be the stepper motor board? The pcb-gcode software?
