The speeds are dictated by how much acceleration/speed the machine has. If I run the spindle a lot faster faster - the polygon will not look like a polygon...

Hal is linuxcnc's hardware abstration layer. It is sort of the interface between linuxcnc and the outside world. It allows you to create virtual circuits and logic to do as you please.

That would be great. It would save reinventing that wheel.

Getting back to the HAL file. Am I right it assuming that is what drives LinuxCNC and you use a Gcode to HAL converter to be able to use Gcode from a CAM programme or hand written.
