Скачать или смотреть Myford S7 CNC Encoder test

This is an example of what can be achieved when using CNC and a quadrature encoder fitted to the lathe spindle of a Myford Super 7.
There are no gears or belt drives between the lathe spindle and saddle lead-screw!
The lathe is set to move in feed per rev mode (G94) and synchronisation between spindle and leadscrew are done using a stepper motor and electronics.
In this example I am using Linux EMC2 for the software and rotating the spindle by hand to show the accuracy between spindle rotation and feedback to Z axis stepper motors
