DBLC,
- Have a look at the programs gcode and see what instructions were given before and after a call for a tool change.
- Then have a read of the Mach Manual relative to configuration . There are three choices Config>General Logic
Configuration.....top left of flyout........ Tool Change.
I will add that you don't need to be a programing wiz, but, one needs to understand the gode instructions given as they relate to ones machines configuration and setup for a job.
Otherwise............ your just driving the car in the dark with no headlights on!
