G-Code, CAD, and CAM discussions / Re: Locating a pocket on Z axis

I don't believe that feature was ever planned for in the NFW.  If you are doing conversational coding like the NFW it SHOULD be there. Other wise you would need to go back and EDIT the Gcode to provide the proper offsetting  (;-( Bummer.

 May want to ask about that in the NFW forum on this site.

(;-) TP

Thanks, but I don't expect to do that from within the wizard. The problem is, I don't understand how to do the offsetting at the start of the pocket and turn it off at the end. Just can't make sense of it.

G-Code, CAD, and CAM discussions / Locating a pocket on Z axis

I've been tearing my hair out about this. The tool is zeroed against the clamping fixture. I want it to go to X56 Y0 and then down to the work surface at Z-6, and then cut a circular pocket using the NFS wizard. The bit I don't get is how to get the correct pocket depth starting  at Z-6 (or any Z other than 0). I will want to cut a series of pockets and slots at two different Z heights along the X axis, and I was hoping to string them together as allowed by the NFS wizards.
This I guess is something to do with offsets?  I have watched the videos and searched the forums, but I just don't get it.

All help gratefully received!


Thanks Ron, that's cleared that one up.


Hi all,
Is it possible to create some code, carry out a test run (on a piece of scrap for example), and then return to the wizards to add a further operation? I tried this but found that the first operation had been overwritten by the second in the main Mach 3 window. This is a bit different from creating a series of operations then testing them all at once.
I'm sure I can save the first code and then the second, and then combine them manually, but I wondered if this could be done without manual editing.

Also: I assume when you post code, it is auto-saved, but under what file name? Is any earlier file overwritten?

Thanks for any advice, I'm sure this is all obvious to the experienced!
