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

    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
