Reply to comment by OldHellaGnarGnar2 in ELI5: why is using "goto" considered to be a bad practice in programming? by Dacadey

Oh yeah. Totally.

I'm not sure if I missed your link about breaks earlier, or if it was edited in, but I just now saw it, and it's super helpful. Our robot programs technically use "JMP LBL", not GOTO, but I basically took them as the same thing in terms of function. So it already has labels for each section if I were to restructure it to use nested loops and whatnot.

All of your comments have been super helpful. I've been wanting to learn more programming for a while, but wasn't sure what concepts or practices I'm not even aware of, and this gives me a lot to think about. I recently got the "Automate the Boring Stuff with Python" book, to use as a starting point, but am still kinda learning the syntax and python-equivalent commands of what I already know in Matlab of Fanuc TP, and haven't really gotten to stuff about code structures or paradigms, etc

Sweet deal, glad I could help and good luck breaking in.

Actually I just scoped out some of your comment history and see you're working in CNC engineering and pop into physics and CAD subreddits a lot...I have an idea for a hand-cranked guitar pickup winder I'd like to design for 3d printing but for some reason I'm having a hell of a time getting my head around how to design the gearbox to multiply RPMs in a reasonable size. A guitar pickup involves upwards of 10,000 winds of a copper filament around the magnetic pole pieces. Motorized pickup winders tend to have speed controls from 600 to 2000 RPMs but for a hand-cranked machine 500RPM seems downright reasonable. We're talking <2oz balanced load. Is that something that might be in your wheelhouse that you could point me at some good resources or fundamentals about? Because I'd love to learn it.
