Here is my 4 speed gearbox comp for my cinci 5 axis mill. It is definitely
inelegant but it works for me.
I use the speed override to inhibit gear changes. This keeps the gearbox
in the correct range per the programmed spindle speed and stops the shifting
if the override causes the spindle speed to cross a shifting point.
It also turns on a pyvcp button the operator must press after a tool
change. This is a manual tool change machine. When the tool change actuator
is energized the button turns red. The operator must turn it green to
restart the machine. This is an attempt to remind the operator to verify the
tool is correct prior to starting the program.
