What would the highest safe RPM be for a 2048 quadrature spindle encoder
on the 7i76.
I have to use some pulleys to mount the encoder on my spindle and I
would like to use what I have on the shelf if possible.
My lathe can go to 2000 RPM maximum but after fitting a VFD it might go
higher. Not

Common on older large CNC lathes is a timing belt pulley that has a bore
sufficient to slide over the hollow spindle.. then a 1:1 ratio to
another large pulley that is mounted to an encoder.

This is the GCode I started out with for my version.

That is very similar to the emco lathes... (they have a 100 line single
channel + index.) Works very well through the printer port.

Exactly what I will have to do.

Clever idea fitting the pulley over the nut.

I have some spare encoders already. As I said, I want to use what is on
the shelf already. To save a bit if cash seeing that I have to replace
the spindle motor that burned out after one hour of working (testing
light cuts). I had to replace it anyway with a VFD and new motor.
