Hi everyone,

I have a problem on my CNC hoping someone can help me out with.

I am running a XYZ plasma table with MACH3, when I jog, stepper motors are fine, when the G-code program is cutting, stepper motors are fine....the problem is when I click the Go Home button the steppers accelerate very fast and fail....same happens when the G-code program is running and the torch travels from one point to another without cutting...the motors fail and loose coordinates.

Why this doesn't happen when I jog or when I am cutting? Only happens when homing or when the torch is not cutting travelling from one point to another.
If I decrease the feedrate manually they work fine. How do I control this feedrate for once?

Thank youy all !
