Extra pulses would make the Z axis move too fast.
Your problem is that the carriage is moving too slowly.
So, I am wondering if something in the signal path is too slow.
For some reason you seem to be losing encoder pulses, the system thinks that the spindle is moving more slowly than it actually is, when the speed is higher.

1. I have installed MS sheet 2 mm thick, 50 laser sloted disc with 1 Z index.
2. Installed Ball screw for extra precision.
still same result, I am not being able to cut proper thread
tested with 200, 300, 400, 500, 600, RPM.

Do the quadrature signals look good in Halscope?

Hello,
can you help me please, where i can found encoder component with missing-tooth function integrated?
I downloaded and compiled latest 2.9.0~pre0 version but the encoder.c component inside it, has no pin missing-teeth.

By adding debounce to encoder I am being able to cut thread @ 600 rpm.
Mine system is Raspbery pi 4 with 2 gb ram.
Now I am a happy fellow.
Thank you all visible and under curtain developers.
