Video on different sensor types

That sounds like just what's needed - thanks very much for the pointer. I read manuals carefully when setting up something like this but if you don't know that a feature is present, it's easy to miss while you are looking for something else. Like the M31 macro (or at least the code inside it), it's a CSLabs extension that doesn't exist in vanilla Mach3 and they're not easy to spot.

Yes there's quite few "hidden" aspects to the cslabs controllers which are good but not very well or at all documented. Like fact you can talk directly to controller using modbus and bypass mach3, which is exactly what the G31 macros does. Gives that bit more control and faster reactions times for I/O.!! . .. So long as you speak the lingo so to speak.!!!
