As promised, here is what little you have to know to run a CNC mill like a Manual Mill with DRO's and power feeds:

To move quickly to a location on the DRO, you enter:

G0 X123 Y456 Z789

That's G+Zero not "Go". Enter appropriate X, Y, and Z coordinates for the 123, 456, and 789.

You need only enter the G0 once and the machine will remember. After that, just enter X, Y, and Z's. If you want to move in one or two dimensions/axes, just enter those. The machine remembers the one you didn't enter and leaves it alone.

To move at a feedrate to a given location, you enter:

G1 F123 X456 Y789 Z101112

G1 tells it to move at feedrate 123. The feedrate is in inches per minute. "F3" is therefore 3 IPM.

X, Y, and Z coordinates are just like for G0.

That's basically it for the simple motions you could make on a mill fitted with DRO's and power feeds on all axes. You could put that on a card and tape it to machine.

There are similar simple commands for turning the spindle on/off, making it go clockwise/counterclockwise, and setting the spindle speed.

If you have a toolchanger, there are simple commands to pick a tool.

Lastly, there are simple commands to turn your coolant on and off.

It's dead easy to use a CNC mill just like a manual mill. Consider yourself armed and dangerous if you encounter a CNC, LOL.
