And that calibration sheet is honestly the most important piece of paper in the whole process. You'd think after the first time you mess up, you'd learn, but I've seen guys skip it over and over again. It's like they think they're too good or too fast to bother with it. But one wrong setting can cost you hours of rework and a bunch of wasted material. I always tape mine right to the tool I'm using so I can't miss it.

The spreadsheet thing really seals it, I've done it myself and it's eye opening. You start noticing patterns like how the tool misses something specific to your vendor's format but catches everything else perfectly. After a month, you can see exactly where you need to double check and where you can just trust it. That proof makes the whole process so much smoother. It's not about perfect automation, it's about knowing your weak spots and working with them.
