Possibly the worst PLA Benchy you will see.
Hello everyone who still has MK2!
I have and MK2 that was given back to my university after a "student use". It was sitting in a closet for 2+ years and now students want to print some parts for stop motion puppets and I turned MK2 back again.
This is what came out from Sunlu PLA on stock settings. Retraction change didn't do anything. Extruder works, I inserted new nozzle but now I am think that it can be a thermistor issue - ordered a new one. Do you have any ideas what else can be a problem? 🙂 Other Prusa - MK2.5s works with the same spool just fine. I know these aren't best printers but I only need them for basic PLA prints to sand and paint over.
Not the main problem but there are signs the belt tensions need attention.
The stringing looks more like a too-low nozzle temperature but I can't rule out damp filament as there are also pits which usually indicate moisture...
And if this is using student-tweaked settings make sure someone hasn't been trying for extra speed.
Cheerio,

Okay, I will look at belts on Monday.
I feel a problem with extrusion but this can be because of wrong temp. The same spool goes great on Mk2.5S in the same room - so I don't think this is due to moisture.

I'll play the parrot that has perfected one line: Make sure filament is dry. Even a new spool, freshly taken from the bag, is (more often than not) "barely printable within a day or two" but not "dry". Fix that, otherwise all other efforts are futile.
Or maybe I'm seeing things. But that stringing looks solid enough to walk on ...
