I can load a program someone else wrote and run the machine all day. But the moment I have to write G-code from scratch or tweak a line, the numbers start swimming. Last week a job needed a small change and I stood at the terminal pretending to think while I quietly panicked about where to even start.
More people experience this than they realize.
You can run the machine, but writing the code that drives it still leaves you lost.
If this sounds familiar, the Library can help you find the bigger picture.
