Breakaway underextruding? S3


Recommended Posts

Posted · Breakaway underextruding? S3

Morning, all-

 

Ive had a horrible time printing Breakaway all of the sudden.  I was printing nice solid models with it but now I cant stop what you see in the photos.

 

temp 220C   bed 105C  55mm/sec   retract 7mm

 

no coasting and I turned off z-hop which helped a bit but now I'm at a loss... after a while it finally gives the no filament error...

 

Thx Much-MadNess

    Hi,

    I use breakaway filament a lot and i find after so many prints that you need to clean out the print core and it starts to extrude right again. So i'm guessing that bits burn and get stuck inside the printcore nozzle that blocks the flow of filament.

     

    So go to "settings" on your printer and pick "maintenance" - "Print Head" - "Print core cleaning" and then follow the on screen steps to clean the print core you print the Breakaway from.

    The print core is clean, I switched out the Breakaway to ABS, no probs ...then ... Im reloading Cura, perhaps saved a setting somewhere.  But, the first few layers are OK then it goes haywire and gets worse...

    Hello all-

    Best I can do with the Breakaway...the photos below are at Cura defaults...no retraction, etc...its stringy  but is solid up to a certain height then the walls get holes and the breakaway becomes even worse...

    What layer heights are you printing at and what temps?

    This is my break away settings for 0.15mm layers on my S3

    Even know the ABS is printing fine, i would still clean out the nozzle if you have not done so as some filaments are more sticky then others.
