linux cnc and closedloop dc motor control was created by guicnc
do i or do i not need a mesa board to do positioning control with dc motors and quadrature encoders on Linux cnc ? or it can handle them directly from parallel port?
dose it do pid same way?
dose it do pid same way?

You can control a DC motor with just a hBridge, and a parallel port
This setup uses the same PID component as a fancier setup using external hardware
The limitations of using a parallel port are:
limited encoder resolution*speed
limited PWM resolution
But it does work:

for example
