More like Gemini when you say anything so you feel smart:

“We don’t sell your data except to provide you with services or products” should be illegal wording. Those two words include 100% of what any company does lol

“We don’t sell your data only if you don’t use us at all”

Then I would suggest checking if you have filament g-code set in your slicer, I guess it’s possible the z-stop was calibrated with a z-offset applied, and when it was removed by setting PLA the nozzle tried to go slightly below 0. What firmware are you running?

From the pic it looks almost like the first layer is still on the plate, or is it etched on? I doubt it’s the latter or your nozzle would be completely obliterated (and it would’ve made a god-awful noise the entire time). Sorry for the dumb question but, are you sure it’s not just filament with incredibly strong adhesion? Does it stop a scraper if you hit an edge?

To answer your question, yes usually PETG is printed with a slight positive offset so the filament is deposited instead of squished. Something like 1/4 of the nozzle diameter

If I/O latency is bad enough it can affect runtime performance from game FPS to browser “snappiness”
