Part 2 of EMC2 controlling lathes refers to threading.
Probably one of the more common operations on a lathe is cutting threads, for that to work the machine controller needs to synchronize the feedrates based on the actual spindle speed. In this example there is an encoder attached to the spindle, and emc2 uses software counting on the parallel port to see how fast the spindle is turning.
Of course this can be done with hardware counters as well (if you have a motion control card that's supported by emc2).
The code
