Hello,
Have had my cnc complete for months and had run some programs with it, mainly engraving. The thing is, Z-axis seems to loose steps, either up or down..
also slaved A-axis or X-axis (dual stepper X-axis) is missing steps causing the gantry do some twist. seems that Y-axis have not loose steps, or I dont only know it.
Here is what I have tried so far
1. Played with speed and acceleration of motors.
2. Changed to shielded cable from motion controller to stepper driver
3. playing with different kernel speeds and sherline pulse mode
4. checked mechanical jams
I wrote test code today for z axis and first it was slowly losing steps and dropping. Then I created another test code and it was slowly rising?????
First code moved Z-axis down as Y and X wasn't moving and Z-axis up with X and Y axis also moving
Second code moved Z-axis down with X and Y also moving and Z-axis up individually Y and X still.
Do you have any thoughts or suggestions ?
I have this chinese usb smoothstepper
