Hello Lynn and welcome to this forum. First of all please make a picture of the tip you're getting after first unload. It's easier for us to see where it might jam.
The green one look pretty bad for PLA. Try with lower temp otherwise it will cause many issues.michael.c31 wrote: ↑Jan 11, 2019 12:58 amthe filament i am using is inland PLA. and the tips measure as follows.
green = 1.91mm
white = 2..04mm
light blue = 2.03
dark blue = 1.94mm (this one hasn't had many issue if any)
i guess what i don't get about the new PTFE tube i thought it was supposed to stop filament from getting bigger than the tube.
edit: which is why i mentioned the PETG it does seem to pick up flakes of PLA (i need to clean my gears) but on a single color print it will start off strong then seems to clog
the green was not in use it was the white filament. and i have lowered the temp and that does help with stringing but the grinding that happens (as shown in my last photo) does not stop. a higher temp seems to lessen the grinding.The green one look pretty bad for PLA.

My PETG looks like your green PLA.
