Interesting. With X, Y and Z, spindle on and off, and feed

happy. If I add a 4th axis, I will add functions to jog the rotary

Be careful with that spindle on button. Consider the situation where you are doing a tool
change and the spindle starts due to the joy stick falling, something falling on the
joystick, or hardware malfunction.

The machines I deal with are enclosed with a door interlock system, your machine is open.

Yes, the cat or the kid pressing the button which you're wrenching the
QC lock wouldn't be good. I'd suggest that spindle start and stop should
be done with "hard" buttons mounted to the panel under the monitor, and
preferably the buttons with the raised collar around them so they are
bump resistant.


Indeed. All it takes is one "Oh ****" to make a fun project a
nightmare.

I just disabled spindle start on joystick, it was a dumb idea.

It was hardly a dumb idea..but having some interlocks and safeties in
place sure makes a hell of a lot more sense.

Thats why firearms have either safeties, or heavy double action
triggers.

As a second thought, I replaced spindle on and off on the joystick,
with flood on and off. Could be useful to adjust the nozzle, and worst
case, I or someone else gets sprayed a little bit.
