Modbus is the most consistent way to set spindle speed, however it sounds like there may be a bug or two in the scripting. Probably best to post over on the mach forum, as I've never used Modbus directly with Mach.
Thanks. Not sure I understand about how to centre the drill but I need to play around more. I understand offsets and how tools will vary. If you have a set size in the chuck (lets say 20mm rod), then you use the edge as the reference. Suppose I could do the drill the same way.

I understand too that Z is set when you face a part, so this is fairly easy. What I'm not sure about yet is when / how do you set your X to Zero (assuming master tool is in the turret)?

Also, there is wiring coming from what I believe to be a spindle pulse generator. Then another set of wires going elsewhere with a part missing in between. I assume this could be some form of 'interface'. Without accurate spindle counts I cannot thread, is this correct? Any other major drawbacks?
