blobs on purge Tower
This is the second one now after a bunch of successful color changes it does this sometimes and it leaves a little pancake of filament in the drivegearbox .any ideas?
RE: blobs on purge Tower
Me and my colleague have the same issues. We tried everything you can think of. Nozzles, maintenance, speed, temperature, more passes during wiping, etc. etc. Prusa team will tell you to use multimeter to measure termistor. Just another bug/error that nobody is willing to fix...
I started discussion here: link
RE: blobs on purge Tower
I've been batteling the blob for 2 weeks now. I tried all the tips i could find and did not resolve the problem. I've been printing creality PETG, because it prints fine and is cheap. After i built the MMU3, problems started like i said. Today I was testing (again) and decided to increase the temp above creality's spec ( 130c). I went to 165C on all 5 colors and was amazed by the result! Blob is gone,and i am amazed by it.
I hope some of you guys get the same results as i did.
Good luck!

Henk - What temperature did you go with? Surely not 165C

Surely you mean 265C, not 165C.

You're right. Stupid mistake.
RE: blobs on purge Tower
I went with 265C, and I am sorry for the mistake.
