Buddy of mine had one crack after two weeks, plastic was way too thin.

Sorry you had to deal with that. I made the same mistake last year with a cheap tent cover and it shredded in the first storm. The old row cover fabric is a smart move, I switched to that too and it holds up way better in the wind.

Bet the real issue is how many shops still don't have a standardized tool presetting procedure. Every time I see a crash from offset mixups it's usually because people are just winging it with manual methods. A cheap presetter or even just a dedicated check station at the machine would've caught that in 30 seconds instead of burning 3 hours.

Yeah I was with you until I tried @carr.willow's way and it totally changed my mind.

Spent $150 to make my GPU run hotter. Real genius move on my part.
