Mach3 Lathe Threading Struggles

[battwell]

you need a controller that will support threading in the controller. this cannot be done in software.
the index signal must be interupt driven- so its very fast.
software will always lag so you will never get the same start point for threading.
you also require spindle encoder - which can be 2 sensors 60 degrees apart
threading- and cheap- are never going to work
