About to pull whats left of my hair out.
I have had the MK3 going on two years now. It used to be the Flawless and my go-to printer when I didn't care about speeds. (Bmabu X1c) for speeds and larger prints, that I need done promptly.
I had an issue with the Prusa, and she got put on the back burner for about a year. I had to replace the hot end thermistor. I finally did this and then went through a full calibration and setup wizard, downloaded the new 2.8 slicer, and attempted to do a 3D bench.
I have now attempted 15 or so benchys with so many different settings... NOTHING HAS HELPED...
It seems that I can't get the PLA to cool enough. The edges and top layer are still molten and very mailable, to the point that you can see the nozzle pushing down the later as it goes around.
The top layer edges are curling up and would love some help before this thing gets thrown in the dumpster.
will try and add some photos when I upload them.
We can't do much without pictures.
Make sure your fans are clean and running freely.
Cheerio,
