Hello All,

I built my own machine CNC router which has been running perfectly for 2 months until my Z axis started playing up.

im running Masso as the controller and Nema 34 Closed steppers.

the Issue is with either the motor or the stepper driver (the error is that its losing steps).

This occurs spasmodically sometimes on homing or halfway though the job.

I have checked and the cabling joins are all fine.

has anyone had this issue or if you have any troubleshooting ideas I will be glad to hear them.


its is the 3rd error in section 2.4
