G71 not working... Am I an idiot?

[Crashmaster]

OK, so the post title kind of sets me up, oh well. I am attempting to use G71 on a controller I have never used it on before. Its a Fanuc 10T, and my program looks more or less like this:

G71P10Q20U.060W.005D1250S600F.012
N10 G0 X.8
S800
F1X1.5Z1.75F.006
Z1.
X1.75Z.625
G2X2.5Z.25I.375
Z-.15
X2.875
N20

The problem is that the control reads the G71 line and skips directly to N20. So now I ask the question.... Am I an idiot?

You have a line that reads:

F1X1.5Z1.75F.006

What is the F1 before the X doing?

I program for Haas not Fanuc and with that F1 removed I think your code would run fine on a Haas. However, I seem to remember seeing that Fanuc needs two lines to set up some of the canned cycles; you would put the P and Q on the first line then the other things on the next line down.

G71P10Q20
G71U.060W.005D1250S600F.012
etc

here is an example from one of my program for a fanuc controlled Daewoo lathe.

That F1 is a typo, oops. It should be a G1. Wisp, thanks for the info. I am actually off of work until next Monday, so I can't try until then.

Try this one:

G71P10Q20U.060W.005D1250S600F.012
N10 G0 X.8
S800
G1X1.5Z1.75F.006 (CHANGED F1 TO G1)
Z1.
X1.75Z.625
G2X2.5Z.25I.375
G1Z-.15 (ADDED G1 HERE)
N20X2.875 (MOVED N20 HERE)
