z axis movement in machine coords.
« on: June 18, 2011, 01:21:29 PM »
Got an odd one here, i need to move the z axis to -32 relative to the machine coords regardless of what offsets are in force. It's going in a toolchange macro to set the z height for the toolchange. Is there a G code to do this.?

Could it be this simple ?

i tried that and it just added the 32 to the current z offset

to get a fast feedrate should i use a G0,

G53 G0z-32.00

or use a feedrate value

G53 Z-32 F1000

the G0 does the trick.

Thanks.
