Hey,

I am relatively new to mach3.

I wrote my own code to cut cylinder with an A Axis.

Ive included a screenshot of my mach3 screen. I cannot seem to understand why my Z axis is going higher then it is being called in the Goode.

I think it has something to do with my G92 call to set the A axis to 0. But I don't understand why that would affect my z axis positioning.

Thank you in advance.

Hey I'm having a similar problem but it is only affecting my x/y axis. I did dig into my code last night and determined that it is definitely the g92 a0 command that is causing the other axis to drift.

Questions for you would be

Does the z axis slowly move out of place while the program is not telling it to move and does it only happen after a g92 a0 command is read?

What cnc breakout board are you using?
