I don't know about you, but I like to do my drilling in the morning. First thing. So in BobCAD I prioritize by features, make my part, set up my drilling, pocketing, and then profiling, etc.

My problem appears to come in with the post:

/(BEGIN PREDATOR NC HEADER)

N10 G0 G54 X3.73 Y8.4186

N13 G83 G99 X3.73 Y8.4186 Z-.78 R.1 Q.125 F3.61
N14 X5.4461 Y8.4369
N15 X8.4461
..etc..

Now...I fire up my machine (Book Machine with EMC2), home it, load the file and hit run. Well, since my machine is at Z0 and my work surface isn't perfectly flat...N10 ends up dragging/cutting across the stock until it gets to N11 which then goes to Z.1 (my safety height) and then it begins pecking my holes...

My question is, since I'm a forgetful sort...if I don't want to modify every single one of my files by hand...how can I get the post processor to force safety height Z.1 first thing no matter what. I'd like to be a drilling first thing in the morning kind of a guy instead of a manual jog to safety height to .1" and then drilling kind of guy.

:banana:

Cheers and thanks in advance.

Nevermind. Watched the video and figured it out.
