Weird blobs on print
Hello everyone,
I've changed my printer nozzle last week from a 0,4 to a 0,25 and the fillament from Prusament Galaxy Black to Prusament Galaxy Silver with relative success. The change was not smooth but I got the nozzle in but since then my prints have these weird black blobs from the original black filament.
This is the current status of my heatblock and nozzle:
What can i do to stop this from happening?
RE: Weird blobs on print
Usually a couple of extra purge cycles should clear out leftover filament but you can also do cold pulls and/or run cleaning filament through the system. Assuming this is it fact from the previous filament, not burned new filament. When you changed nozzles you may have loosened the heat sink so filament can squeeze out of the hotend and burn but your heater block looks reasonably clean from the pictures.
