Blob ruining everything

When my printer prints the first layer at the start of the first line, it might be a little uneven. But when another line joins this one, some filament will stick on. Imagine using a hot glue gun. Run the nozzle over a hot glue line, and some molten filament decides to hitch a ride. What happens is that the nozzle might rip a portion of the line off because of the sticking, and the butterfly effect until the whole print is ruined and I have to stop the printer.
This problem has been getting worse once I started using PLA matte and Timmorry TPU.

Also the purge strip kinda works. Blobs will deposit. But when the nozzle comes back the blob gets on again. So I have to poke around during the print to remove stuff that might ruin the print. And I don’t want to accidentally crush my finger.

How are you cleaning your bed?

are you using your silicone sock to protect it from sticking to hotend?

If you need to do something with the nozzle, don’t try while it’s running, pause it, do your thing, then unpause it. In addition to crushing your finger, there are other things you could screw up by messing around with a moving nozzle.

Are you drying your filaments?

yes. I did use the silicone sock.

If I pause it it will ooze. I’m doing stuff to the print, removing blobs.

I’m using soap and water. Sometimes I use alcohol.

I’m not. But I got the filament around the end of 2023, and the place I live isn’t too wet.

Dry the filament. Use orca slicer calibrations on the specific filament for your printer.

If I stop a print, it oozes, but it doesn’t ooze if I pause it, the printer does some retracting during pause.

Actually, most of the time the print is hopeless and pausing won’t help either.

Um… It adheres properly. It’s just that the nozzle rips it or sometimes at the very very start there is uneven extrusion and everything else that causes an end of the line to detach.

I’ve found a solution. A skirt is a sacrificial object, and then I can move on to the real print. But another thing is that it troubles me that I’m the only one having the problem.

Perhaps the others dry the filament and calibrate it. :smiley:

tried before. Doesn’t change.
