Pucking up plastic with my nozzle.

PLA with additives, like your gold PLA, cause problems with all-metal hotends like the M.
Try, as an experiment, setting your retraction to 0.

I had an microseiss it didnt do it but ill take your word for it. So the pla isnt the issue its the plastic on the nozzle . I know it has somthing to do with. The pla because it doesnt do it with other filaments?? I mentioned the pla be ause it mught give someone an idea whats going on its one minor
Left out item .... i think ???? -
its the small bits left on the print wher they dont belong there.. )the nozzle.pickes up the peices untill its covered all the way to the thereads of the nozzle
no clue on why -
@ziggymanpopo covered all the way to the threads sounds suspicious. Are you certain that the nozzle is screwed tightly to the heater block? If not, plastic can leak from the threads because of the pressure inside the hot-end.
-
yes im sure that was my fist thought too
-
Ive also spent.hours watching it.slowly build up from the tip of the nozzle
-
PETG is well known to collet nozzle crap that way. PLA has much less of an issue that way.
Sorry, I haven't got an answer/suggestion for you. -
don't be the suggestion is appriciated,, it's try somthing else besides pteg,good call,, its just that i tried pla and was told it doesnt like all metal hotends W/additives
fact being with a high end hot end i should be able to run it no problem and my microswiss ate anything i gave it... that was my thought...ive even ran petg on my anycubic that cost 200$
so I'm pretty sure that it's a setting or a combo of settings hate being a newbie
lmao... im close to being able to tune this stuff to this degree -
I've had problems with PETG building up on the nozzle. I have largely eliminated the problems by 1) reducing extrusion to 95% and 2) eliminating lift on retract. I also recently bought some filament that seems better than stuff I was previously using, but it could be that the other changes had more effect than switching filament brands.
-
@mrehorstdmd , those are the two things that I find necessary for PETG as well but I don't do them for PLA.

Thanks im gonna try some of the suggestions here and i ll leave this poast open.
I would like to add that i have not set all the g code parameters so there could also be an issue with things likenjerk p a or other things i woupd not know ???? Any input is appreciated. thanks all -
Had a thought
Could i be pulling filament up before it cools because of too high of retractions... i had it sat at
1.5 mm???? -
For refreance the 95% extrution solved most of the gunk on the nozzle thanks for the input guys
