Dear Answer Man,
I was wondering what the G- or M-code is for variable spindle rpm while turning. I heard there is one that quickly varies the spindle speed up and down during a cut to avoid chatter.

Dear Answer Man,
I have a dust extraction vacuum on my GR-510 gantry mill, and I want to turn off the vacuum before every tool change. I am trying to alias M06 to run O9006 whenever an M06 is commanded.
