RE: Underextrusion and nozzle clogs
Well no wonder it was rather hard to diagnose then with wrong/defect replacement parts in the mix.
Bold move complaining about Prusa customer service for not antizipating that...
Have fun printing!

It's a PhD thing... not the first time I've experienced the same attitude with pieces of paper.

I was not complaining to them but asking for assistance.

You are an ASS
RE: Underextrusion and nozzle clogs
Not sure that's a complement or an insult. Most of the PhD candidates (and post-docs) I've lectured to call me Brutal.

[...] This made the temps read 15-25C hotter than they actually were.
So dodging all the mines here... That explains why PLA worked and PETG didn't I suppose. Unlike most of the issues we're seeing this time of year, yours was truly under-temp. Sounds like your PLA was OK at lower temps but the PETG needed more. Just out of curiosity, what temp were you setting for PLA? Prusa's profiles tend to run hot.
The reason I'm asking is this sounds like a useful diagnostic, especially if someone doesn't have diagnostic equipment available.

PLA 210/60 PETG 245/85 Resistance for the thermistor is around 100K

Results make sense. I don't have much luck with PETG at the cold end. 240C gives the best inter-layer adhesion. I haven't done much temp calibration other than the on-board routines, instead just focusing on finding what works best for each filament with the settings I've got.
At least now if you have stringing problems, you know you can print that PLA a good bit cooler!
