Oh man, that sounds like a total nightmare. So you paid three hundred bucks for a fancy sun sensor instead of a camera. Thanks for the warning. Miles72 must have gotten the one good unit they ever made before the factory gave up. Honestly, yelling directions over a glitchy screen is how they did it in the 80s, maybe you just got a vintage model.

Watch a rotary cutter skip over a fold like it's playing hopscotch. You're left with this sad little uncut thread holding everything together. It feels like the fabric itself is mocking you. My last project looked like a kindergartner with safety scissors got to it.

Yeah, @the_joel is right, seeing that new growth firsthand changes everything.
