I am current building a cnc lathe controlled via the etch servo configuration since I am using brushed dc servo motors.
I wanted to add a single channel spindle encoder to do some threads. the spindle speed won't be controlled via the software. I tried adding a third Z axis and configuring its encoder to counter mode and the axis as an angular wrapped rotary axis. the counter mode seemed to work but the wrapped_rotary option didn't. so this method didn't work for me.
what other way can this be done? did I make any mistake in how I tried to achieve the spindle axis?
Spindle must be controlled by LinuxCNC for threading.
And spindle encoder must be set as spindle encoder, it does not work for threading as axis encoder.
Does the encoder have A, B and Z or index?
the encoder is based on an optical sensor and a slot wheel it has a single output. I was planning to use the missing teeth indexing scheme.
how can I setup the encoder to be a spindle encoder? what do I need to modify in the ini/hal files?

I think at minimum these pins must be used for spindle sync.
spindle.0.revs
spindle.0.speed-in
spindle.0.at speed (at least set true)
spindle.0.index-enable
You only need to control the spindle if you are trying to rigid tap.
