Stringing
Hi,
I purchased the preasembled kit from the Store. The prints are awesom, but I have an massive stringing problem.
To the problem:
Since I purchased the mmu2s, I assembled the mmu without changing the parts on the printer. So its still like the Team from prusa assembled it.
BUT since I updated the firmware I have an massive stringing problem. After the update is succesfull, the printer is completly resettet. So I followed the menu and calibrated the printer as he wished.
Also I made an PID tuning and and temp calibration.
I did not changed the Software on comp.
Does someone have an Clue?
Also I used original prusa filament. With Prusa settings.
RE: Stringing
Can be several reasons, check this out:
Before you do anything else; dry your filament.
Cheerio,
RE: Stringing
Just to be sure: did you change the printersettings in Prusa Slicer to the MK3S with MMU?

RE:
Buyed Filament Dryer, will be here on wednesday to test.
And
I did not changed anything on Slicer. Its still om mk3s+ without mmu
RE: Stringing
And?
Did drying the filament fix your problem?
RE: Stringing
No, I have them all dryed in a box.
2 different humidity sensor says 10%-13%.
I downgradet to an older version, same problem. (with all clibration, also pid tuning to 210 ..)
Meanwhile I put the MMu2S on top and checked the cable from the temp sensor, he is full in.
But.
When I go down with temperature. there is zero stringing.
So f.e. I use prusament with 190 grad, no problems.
excelent print
My gues: the temp sensor is strugeling. bad for an 1 month old factory assemblet printer 🙁
Any other clues ?
RE:
This is my current print, no stringing with mmu2s and temp set to 190.

It's a common misconception that you can dry filament in a "dry box" (with desiccant of some form in it), those are for keeping filament dry not for drying already wet filament. You need a filament dryer, an oven or a food dehydrator for that....

I Used this one ..

An low-cost self-built dehydrator with adjustable temperature (40-70 deg.) and drying time (1-24 h.) :
and a guideline of drying values:

Yeah, this is correct. If you need to remove any moist from filament, food dehydration or bake it in oven are recommended. Once they're dried from dehydration/oven, just transfer them to sealed dry box with desiccant or silica gel to keep filament dry all the time.
RE: Stringing
You can not See it, but I posted a pic above with the sunlu dryer i used before i put them in the box.
Somehow the post needs to be moderated, so all can see
