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,
