stringing/over extrusion
Hi guys, looking for suggestions.. I have a brand new assembled Mk3s+ I bought on black friday direct from Prusa. I've got a file that I use on my other prusa's and resliced for the new printer. It printed the set of parts amazing on the first go (it's a 6 hour print at .15 layer height) using PLA Plus from Duramic. I've used this filament dozens of times.. anyways, it printed the parts flawlessly for 6 or so sets and then overnight printing on the 7th set I woke up to a huge mess of stringy parts (below). Nothing changed and I've been trying to trouble shoot it. I changed filaments, cleaned the nozzle, checked extruder tension. I was able to get it to print 1 more nice set of the same file after cleaning, but then the stringing came back on the next print. I'm not sure what it could be??
Thanks
RE:
please take photo of nozzle and pinda from a side on also have you tryed lowering the temp by 5 or 10 degress

RE: stringing/over extrusion
Here you go. No I haven't tried that, as this material prints well at the standard temp on my other prusas (and did for the first few on this one).
RE: stringing/over extrusion
Your pinda is very low try raise it a bit then redo first layer

RE:
Did you check the grub screw inside the extruder, the one that holds the bondtech gear on the motor shaft? If that gets loose (happens on newly assembled printers) it results in reduced retraction which could cause this type of stringing.
PS: Your PINDA is fine imho...
Additionally: If your print was fine before, and you get problems with the exact same gcode (settings) than before -> Do not change the settings (like temperature), find the thing that changed. Do not change something that worked before, something has changed already, find that thing.
If at first you don't succeed, skydiving is not for you.
