Looking forward to seeing some interesting jobs I haven't really thought about. Bonus points if it's an IT job.

I've done some gcode but moved onto other programming(mostly c# so completely different. One thing I HATED about gcode, I don't know if it was just my machines or gcode in general(most of mine were based on fanuc cnc controllers typically seen as top of the line) , we were not able to name variables.

I create a variable and assign it #315. What does #315 do? What does it mean? Who knows... Better have notes or comments to explain or your fucked. I can't say variable x_offset_tool_15 nope...just #315.

I worked with Fanuc control machines for 20 years up until 2023. Sounds like you were needlessly in macro hell. Just declaring an offset will use either an H (typically height) or D (typically a radius offset in Fanuc controls, but sometimes they are setup for diameter).

It would go something like this:

G40G49G80G90 (CLEARS OUT POTENTIALLY PREVIOUS GCODES);


T1M06 (EXECUTES A TOOL CHANGE, LEAVE OUT M06 IF JUST DECLARING THE TOOL);


G43H01 (DECLARES H01 AS THE HEIGHT OFFSET);

G00ZO.O1 (MOVES THE TOOL 0.01 ABAOVE WORK);

G41D01X1.0 (DECLARES LEFT HAND TOOL OFFSET AS D01);

You don't need true macro variables for 9/10 applications, or general operation. I feel like you got placed on some overenginered solution.
