What is "manual M6"? Something other than an M6 in gcode running?
I understand that if I MDI T2 M6 it will be idle at the end of that. Is that the same in gcode running along, T2 M6 happens, machine stops waiting for me to change the tool, I put in the new tool then I can jog around, set my A, and press cycle start and off she goes?
Perhaps that's gcode behavior since time began, but I've never thought to do it or did it!! Cool if that's they way it works. Maybe you CAN teach a 70 year old dog new tricks.
