I have been trying to build and program a CNC router on the back half of the plasma cutting table, but can’t get it working. !After assembling everything I need mechanically, I have recently been working on the software. A plugin for SheetCam TNG lets me generate G-code files for V-carve routing, but these files don’t run in my motor control software Mach 3 CNC. At the start of the G-code file, the program gets stuck between lines N0100 and N0110 (see attachment) at the G92 command, where it tries to reference the Z-Height using a limit switch; however, unlike the plasma cutter clamp, there is no limit switch mount on the new router clamp (see attachment). The fact that there is nowhere to put the limit switch leads me to believe that there must be a way to ignore the G92 command in Mach 3, but I have been unable to find such a setting. I can CAD and 3D print a limit switch holder, but it seems like I shouldn’t need one. Any help would be much appreciated.
Have you tried using a different post processor file to generate the g code, like the Avid CNC post?
Agree with @asid61 you merely need to either find the correct post-processor OR edit the one you have to exclude the offending command(s).
Worst case: Manually edit/find & replace/remove all the G92 commands.
Altering the G-Code worked for a short term solution. I changed line 100 from G28.1 to G28 (not sure if this one was necessary but it seemed to help), and I deleted the G92 commands from lines 110 and 130. I also deleted M03 from line 150, but this is just because I don’t have the router plugged into the control board yet. Thanks for the help!
