Need Help!- G84.1 ???

[masonbcaldwell4]

When I give the 4020 a G84.1, the whole thing locks up... I'm just learning CNC, so I may not have given it enough info, so what should a typical line look like? Is this code, a rigid tapping cycle, a feature or option? if so, is there any way to tell if the machine is equipped with it?
Thanks in advance,
Mason

N63G8 (G8 TURN OFF FEED RAMPS)
N64G0G90G54X-5.7Y-1.19S420.2M5G80M90 (S420.2 PUTS THE MACHINE IN HI GEAR)
N65G84.2 (PREPAIR TO RIGID TAP)

N70X-0.35

I dont know how to tell if your machine has the Rigid Tap option.
hope this helps

Look at your spindle vector drive. The tag should say "RT Ready" if not you don't have rigid tap. I think you can go to the enter next command and type SETP (Rigid=Yes in SetP) and it should tell you what is installed. just don't change any of the settings.
