There is a conductive material with graphene content, called Koltron G1. Never tried it, expensive but available also in small 100g rolls

Are the temps set correct in Cura? (This is actually for PETG). You have four different settings to play with.

I dont know the moisture limits for UM PVA, or if this is the only reason, but if stored in a room with 30% humidity a longer time it will break in the bowden. This is from my own experience. I would be worried about temperature cycling for the equipment though. That cold in the mornings would likely cause condensation

Agree at some point, for the home use versions . They always shout "the wolf is coming" but this is enterprise version and actually the first warning I see in about 10 years...

Getting security warnings when downloading Cura 4.6. Never gotten this before, is anything changed in the way you handle latest version ?

Hi, you can get a lot better result if you enable Ironing (at the end of Shell tab) Depending on material you can get good results with 4-10% Ironing flow, begin with 5% and see how it works.

1. Clean the printcore with pla or cleaning filament. 2. Make sure the nylon is dry. If your printer is fully enclosed you can heat the bed to 60° and leave the roll in there for a coupple of hours. Moisty nylon is prone to clogging nozzles. You can also open the feeder to clean it. Last time I had problem with random under extrusions I opened it and found a small piece of filament that probably interfered at its own will. Be careful though, there's a spring inside that wants nothing else but jump out ejecting other parts...

You should be able to get quite good quality on the walls with PETG on a UM3. Example here is a simple tool rack but coming out nice with most of the settings as of the cheat sheet.

I use PEI sheet from Build Tak and they work well with active levelling. The standard build Tak works but the heated nozzle melts the surface during levelling leaving small craters

If you use the link I posted above, pick one of their petg materials then you'll find "Cheat Sheets" for different slicers. This might not fit materials from different vendors but it will be a good start.

I think your problem is infill speed. I have reduced it to 40mm/s otherwise it will create blobs like yours.

Sorry, should have mentioned that I haven't tried them myself, yet...

Maybe insert threads could be a better option. You heat them and press them in. Guess you haven't seen a tap like this neither. 😉 Designed for difficult materials to reduce friction while tapping .

Send them a request, they are the manufacturer so they might be spooling soon.
