An Arduino is possibly a better choice. You can get Nanos for about £5.

But quadrature has one huge advantage over regular counters, you get both

It's pretty easy to read GPIO with LinuxCNC, and at least as easily as
with a Pi.
Now, an Arduino with dedicated

I put a CUI ATM-103 encoder on my spindle motor. I’m using a parallel port
card and a BOB to interface my steppers and spindle. The spindle uses PWM
pulses and I’m able to receive the encoder inputs directly in to LCNC via
the BOB. With the encoder set to 100 PPR, it would lose count of the rpm
Hello,
I have been following this thread. I wrote some code that runs on an
RPI that can read a quadrature encoder, I have a few of them, with

I also have a few encoders that came with some stepper motors I got my
hands on, still have to play with those to see what

It's HAL. You can connect any encoder to any axis and control it with
any stepgen or pwmgen. There
