I return empty spools and waste material (PLA only so far) to my supplier

Thanks, I was browsing there but couldnt see the forrest because of all the trees 😉 Found it now

Have you opened that support channel recently Sander? I knew it was coming and its greatly appreciated but havent seen it announced nor can I find a way to it appart from your link. Great news indeed. 👍

I think the answer is in this thread, firmware is the problem

I'm on the latest firmware and I can't recall it happening when I installed it. Might be worth getting back one step just to try.

2 years ago I sent such request about a print core, answer we will get back to you soon. Still waiting. One year ago a fan broke, still under warranty, answer we don't have any in stock but will send as soon we get them in. Still waiting... No need to say I went to other channels to get my parts but it's annoying and it stains Ultimates brand. Luckily there's a new reseller close to me now, that I know in person, so they will be getting all my request from now.

I havent been at the office for a long time but yesterday I was in and had some time to fiddle with the printer. Ran diagnostics test of the bed sensor and it reported low performance. Found that both wires was broken, surprised that the test only reported low performance. Repaired them and diagnostics now looked good. However problem still persists. Tried to swap cores as suggested, core #2 still gets pushed hard into the plate preventing filament to be extruded. At least confirmed problem isnt the new core. Automatic levelling seems to be ok for both cores though. Doesnt push down core #2 much while levelling. I also realised that I have changed to a Build-Tak Flex plate shortly before using the new print core, might only have printed with core #1 until I installed the new. Suspecting core #2 "thinks" I'm still printing on glass plate level and ignoring data from levelling. Could that happen and is there anything I can check or try? I will remove the flexplate and try a print on bare glass again but that will be next week I hope. Open for other ideas to try and check.

Yes, it would be so much easier if Ultimaker made all there official re-seller list all spare parts. Or even better, open their own after market webshop for spares.

Did you have support enabled when you printed that part? I always enable support interface. prints a solid slab which improves surface quality of suported areas. Depending on what support material used you might need to vary distance between support and part. Zero if using PVA, more if same as print. Below example is supporting TPU with PLA

Check your export settings, I suspect you export in imperial units but Cura reads as in metric, 3/4" would then be 0,75mm. It doesnt look like you are using Autodesk products, they are known to export in wrong units. You probably also have Cura preferences set to scale tiny models. If Cura scales it will print at that scale.

Just tried and it crashes, or hangs would be a better term, for me too if I have Cura on secondary display. No issues while on display 1. If I drag Cura to display one it release immedeately

Interesting to read they are sintering in Hydrogen, trying to create a new Hindenburg are they? Would have expected to read Nitrogen or Argon

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
