Prusament galaxy silver PLA won't stop balling up  

RE: Prusament galaxy silver PLA won't stop balling up

Prusament Galaxy Silver is one of my favorite colors and I’ve printed many many rolls of that filament with no problems. I also have the Bondtech extruder. It’s certainly possible that you’ve received a lemon. Sometimes (but rarely) happens. As it was still sealed I doubt it soaked up humidity and what you described doesn’t sound like that. I would redo Live Z for this filament to make sure you have a perfect first layer and print a temp tower. What temperature is your print bed set to? Maybe adjust the tension screw on the extruder to see if that makes a difference?

@fuchsr

I concur.  Clean the bed and redo your Z height

Nice, thanks folks!  I definitely clean after every print and I can give a re-z + a bit more extruder tension a shot.  After that I'll take a pic of the results.

Thanks.  A pic will defintely help.

So this is a normal print with some pet-g.  9h until I can put the pla back on there.  🙂

Oh for the love of.... it's working fine now.  Heiseberg principle perhaps?

I see your using the PEI sheet. I followed all the Prusa recommendations regarding cleaning with IPA, but I couldn't keep the first layer from coming loose. Even when I tuned my Z until the filament was smashed on the bed. What I found that works for me is Dawn dish wash soap. I wash the plate before every single print now and it seems to be doing the trick.

What did you do to fix it? Having a similar issue. Was able to finally print the “Prusa” logo but can’t print a whistle or benchy. Won’t adhere to the bed.

I too regard the Prusa silver-gray PLA that comes with the printer as the gold standard as to how a filament should behave on the Prusa printers.  Unless I have a specific reason not to, I'll switch to that filament when doing a Z calibration.  I've found that when the Z is dialed in with the Prusa silver-gray PLA, most any other filament will properly print as well.

I've found a good second-source of this filament to be at the online store of Filament PM here in the States.  I always keep it on hand on the spool rack and use it whenever a silver-gray PLA is the desired media for the job.

If this filament will not properly print (assuming that it's not a one-off bad spool or wet or damaged) on the I3 series, something is definitely wrong, most likely the Z calibration.

...

So I've done a number of things, including a full recalibration after printing the mini base feet.  I'm not sure which thing fixed it, but starting fresh with a full printer test and a first level calibration are probably a good thing.  It's been really good since then, and the only issue I continue to have is when I download an internet stl with multiple objects in the print.  So I separate them out and everything seems fine.  I hope you have luck soon!

Calibration

Calibration or sheet cleaning are the top ways to increase adhesion.
