I wonder whether adding something in the Filaments/Edit filaments/@USER section of the XL screen would take care of the "incompatible filament" message?

I'm still learning how to preset filaments in the slicer. LMAO I'm a slow learner without pictures. 

*pasted

I REALLY hate to even post about it just yet.....however....I installed a .6mm hardened nozzle last week and have been printing 3D Xtech ESD PETG flawlessly from a 2kg spool since I swapped to the larger nozzle. I wouldn't consider it a 100% fix just yet, but I've completed almost 40 hours of a few different prints and haven't had one issue since. 

Kind of stoked about it. I did setup a custom filament in the slicer and modify the nozzle temp about 10 deg hotter. Now I get a "incompatible filament" message every time I print. That's always nice. 🤣 

Just a follow up on the progress.

Looks like we have an official fix

Emailing info@prusa now to get a parts kit or whatever they can offer. Thank you for following up with that info!

Glad I'm not the only one loosing my head over seemingly unexplained failed prints. I recently had one head that started consistently failing to extrude mid-print while all the other continued. Coincidently it was right around the time this post started.

It sure is quite frustrating to lose a print mid steam especially when the prints are 12+ hours long, over and over and over and over ..... and over again. ESD filament is almost $100 a roll and I've sure wasted my share of it. Try the new connector backshell and stabilizer mentioned above. It "seems" to have fixed mine. I'm heating up for a 12+ hour print now so we will see if it finishes or not. 

I get that its cool to 3D print the printer parts and that all the parts are open-source and all that jazz. However, most of the time that fixes on these things wouldn't need to be fixed if the original printer parts were injection modeled with good material from the get-go. It's a narrow, razor's edge, but some of these parts are nothing shy of sketchy from the start. I've even contemplated having our machine shop machine some of them out of aluminum so they will last until I retire. 

Have a great Monday, all!

Currently printing the previously mentioned extruder parts in PC-CF to see if I can save my sanity (...I mean save my printer from my sanity).

FWIW, My printer was a 5-head Day 1 pre-order, and I have been using the enXLosure since it was posted. I recently also put covers over the grill behind the extruders (because it sits up against a cold Canadian window).

Based on what I see here, having an enclosure is definitely a defining factor for this issue.

SURE APPRECIATE ALL THE COMMENTS AND HELP!!!!!!!!
