I'll probably have a few post processor questions so I'll use this topic to keep them all in one place and document my customizations.

I'm running a Grizzly G0704 mill converted to CNC with travels: X = 19", Y = 9", Z = 12" using Mach3 as the controller.

In looking at the BC supplied posts (for a Mach3 controller) I see a block at the start:

(BEGIN PREDATOR NC HEADER)
(MCH_FILE=4AXVMILL.MCH)
(MTOOL T5 S1 D.1875 H2. A0. C0. DIAM_OFFSET 5 = .0938)
(SBOX X-2.125 Y-2.125 Z-.125 L4.25 W4.25 H.125)
(END PREDATOR NC HEADER)

I understand that Predator is a gcode editor and back plotter. I use GWizardE from CNCCookbook so I don't really use Predator (and I don't think I have a license for the back plot capability). So, the question is, is there any harm with removing the predator header? I would think not.

I saw on the BC forum that someone asked about launching GWizardE instead of Predator last year. Seemed that there was an issue with GWizardE at the time. Not sure if it's been fixed yet. Does anyone know? If not, I'll take a look.

cheers,
Michael
