Look at this!

Has anyone seen a failure this bad? PVA raft and supports with PETG filament. Set to be a 49 hour print but this was just overnight. The last layer of the raft quit before it was complete then the PETG found its way ALL around the heads.

Bad support. You should have a big connection area between both materials. Or use PVA only for dense...

That was me with Hatchbox PLA a few months ago, plus a 7" volcano under the nozzle.

Hi, How did you clean it? I have almost the same problem with different printer

I had a similar clog on my ultimaker 2+. Depending on the filament, heat the hot ends between Tg and Tm and it should be soft enough to come off with some help.
