UM3E First Glob of material stays stuck under print head

Recommended Posts

Posted · UM3E First Glob of material stays stuck under print head

Hello everyone, I am having often the same issue:

When the printer starts a print, she does a small glob of material in the top front corner, but I often had that glob stuck under the print head and ruining the print, so the only solution I have found is to wait and remove manually the glob before it starts the print.

More often when printing with ABS, and really often with PVA

Hi Swissengineer,

thank you for your post. Sorry to hear that the little blob of filament makes it to your print. Do you print with a skirt? Usually this skirt also functions as a buffer to catch these kinds of things.

Looking forward hearing from you!

Yes I am always printing with brim, the problem is , even with the first brim catches it, it still high enough to get under the head and being dragged around...

Bumping this -- as this happens from time to time with my prints as well when the blob doesn't stick around the intended waste area.

I find the skirt helps with this sometimes...but sometimes, that blob appears near the nozzle and despite the best attempts to tweezer it off via pause....another one will appear!

This happens frequently w/ my UM3 also. I always manually remove the blob now. Sometimes, the blob will release from the extruder just fine, but then get stuck to the bottom of the fan case.

Hi Swissengineer,

We are aware of the 'blobs' not sticking to the build plate and we are working on a solution to the problem, thanks for reporting!

Sadly, I can't give an estimation on the fix date just yet. :( Keep an eye on the changelogs when new Cura's are released if the issue is fixed.

Regards,

Jeroen

Hi Guys,

The bèta is online for a week now, has anyone tried the new function?

It's called 'Enable prime blob' and is placed in the 'build plate adhesion' category.

Regards,

Jeroen
