LinuxCNC EMC2 HAL Files: 3 axis mill, 2 axis lathe with encoders, jog wheel, axis compensation, camera view

Due to frequent requests – here are the configuration files for my LinuxCNC (EMC2) controlled mill and lathe.

The mill is a 3-axis machine, with stepper motors and jog wheel (see earlier post).

The lathe has 2 axis, stepper motors, and digital readouts. No feedback on the readouts, but they are great for highest precision work. Configuration files also include the setup for spindel-synchronized movement and spindle speed readout. I have run spindle-synchronized toolpaths for cutting regular and tapered threads with no issues at all, up to a few 100 RPM. The GUI (axis) is also configured for use with a little camera that is very handy to set the coordinates of the tools.
