UM2+ Blobs/ooze

[komodo 4]

Hi Guys,

Any idea what's causing this to happen? Using an UM2+ with Porto-Pasta Carbon Fibre filament. No heated bed, extruded at 235°C. I can print the exact same part on my other UM2+ with identical settings flawlessly. No idea why it isn't printing on this one. Also having the same issue with my UM2.

Cheers

Rich

just a thought - could it be due to variation in the temperature sensor between the two printers ?

It looks like your printing too hot to me

interesting design too

Yeah that was my thoughts as well, but to get that sort of result I would expect at least a 20°C plus temperature error. Can they really be that far out between 2 printers that are the same model?

Sorted the issue, hopefully on both printers. On the UM2+ it was a partially blocked nozzle, so a couple of atomic pulls solved the issue. On the UM2 with a Bondtech feeder I think its wearing of the drive gears. So just waiting for replacement ones to arrive to see if that fixes the issue.

great news it sorted

re the BondTech, I periodically open and clean the feeder gears to remove filament debris with a stiff brush (not metal) - seems to help with extrusion when I have problems

good luck
