I’ve just added the new T8 leadscrew and coupling and have the latest MPCNC813_GLCD_T8 firmware.
My issue is when I set a depth of cut to say 1.5mm, the Z axis usually starts off
Ok. Then after a little while the Z axis gets deeper then 1.5mm and begins to cut through the job, not lifting above the work.
I have tightened the coupling and grub screws.
My previous threaded rod worked great.
Any help would be appreciated.
