I ran across this more by mistake than by design. I have modifed my
Post to do the following:
G70
F84
G90
M05
G4P1
G01Z0.500F40
G00X11.780Y3.789; move to start of cut
G01Z0.250F40 ; lower head to .250 (piercing height)
G4P1
M03F80 ; Turn on torch, reset speed to 80 IPM
G00Z0.135; Lower head into cut at full rapid
G01X11.670Y4.013; first line of cut params
The above works fine
By chance I edited and changed the G00Z.135 to a G01Z.135 and the THC
hold does not work. The program takes off prior to the arc being
established.
So with the THC on the following does not recognize the HOLD.

G4P1
M03F80 ; Turn on torch, reset speed to 80 IPM
G01Z0.135; Lower head into cut at 80 IPM
G01X11.670Y4.013; first line of cut params
Weird huh? The max speed on my Z is 60IPM but why would that effect
the program Hold on the THC? It lowers okay but the arc starts about
1/2" from where it should since I have no pause on Spindle Spin up.
Normally the THC hold takes care of it.
