Your machine is probably not able to use the G80 series of Programs, I would think you have G70-G76 codes. The machine probably does not have rigid tap so assumming that, I usually use a pull-out or compression tap holder and program as follows.

N10T1000
G00G97S100M8
X0Z1.0T1010M3
Z.2
G98G32Z-(DEPTH OF THREAD)F(1/#0F THREAD)M5
G32Z.2M4
M5
G99Z1.0
XOZOT1000
M01

PROGRAM THE FEED GOING IN AS A SLIGHT AMOUNT LESS AND THE FEED COMING OUT A SLIGHT BIT MORE SO THE THREAD DOES NOT PUSH OR PULL ON THE TAP.

Your machine doesn't support G84 that's what it's mean.
