Fixing Minor Issues - Adalinda Print Test
Hi everyone,
for the last couple of months I had a problem configuring my Mk2 after moving it and not using for a long time due to some family tragedy.
Yesterday I finaly got it printing with acceptable quality (did the configuration square from the "Z adjust my way" thread and the print came out perfectly in every way.
After that I ran the Adalinda print I got with my printer. I had the printer since early June 2017 but have only used it for a month before we had a house fire so the printer moved around to my parents' house and wasn't used until the beginning of 2018. (I want to point out that the original PLA that came with the printer stayed on it for the whole time - I haven't stored it separately during this time).
I am attaching some images of the print. I am overall happy how it came out, but there are some issues I'd like to fix (some stringing on the wings and head e.g.). the biggest issue is the piece of filament you can see wrapped around the dragon's front left leg. This piece is not missing from the print, it just seems as if on this point there was a problem with filament overflowing from the nozzle. This was the second time I attempted to print this yesterday, first time the same thing happened on the same leg, in the same time (around 1 hour and 5 minutes after print start). First time I stopped the print cause the filament was getting hit by the front fan guide. The second time I let it continue and it was finished in 7 and a half hours with no issues (except the minor quality problems you see on images).
I have also noticed on other prints that I have a big problem with first layer above supports. The first layer (especially if it is a round profile) will stick very badly to the spport and I get a polygon instead of a circle (that is when the circle is parallel to the heat bed).
I suspected I have some cooling fan issues, but both work fine. Every test on the Prusa gets passed and I have no problems with the unit itself but those small imperfections.
The other issue I thought of was the filament quality dropping over the time not used, but I have more than 200 m left in this spool so I'm kinda reluctant to get a new one.
I also thought I had some underextrusion problems, but after this print I really doubt it.
Here are the images and I hope someone can help me this time, or give me some tips (I've included problem info in each image description):

Seems like you have troubled times behind you. Hope all is well now.
I'll take a look at my adalinda to see where it differs / it's the same. What I can say now is, that I also had the problem with the belly / overhang.
Why do you think you have overextrusion in the first layer? To me it looks more like the gap between Nozzle and bed it too big. (nozzle too high)
Re: Fixing Minor Issues - Adalinda Print Test
Hi darKing, thank you, everything is great now!
I think there is an over extrusion problem because if you look at the second image on the link, you can see the line going from the front paw to the belly. I think there is some z hop involved so the line isn't pressed perfectly onto the bottom layer, and i probably damaged it while removing the print. The other thing is excess filament around the first leg (picture near the end). This was simply excess filament, there are no gaps in the leg after i removed this ring around the leg. Lines are perfect so there was simply a conituous extrusion when there ahould have been none in my opinion.
You can also see an image of the bottom layer, apart from a few scratches I've made while removing the print, I think it looks really good - no gaps between infill or between infill and perimeter wall.
So this is why I think there might have been some over extrusion issues. I don't know if this print is programmes with retraction, so maybe this is a part of the issue.

That's my Adalinda, pre-sliced from Prusa.

Funny thing is that my Belly and the string around the foot are somewhat similar. However, the your layers look really "thick" and you still got some holes. Hmm... odd.
The MK2 Version of Adalinda is also .2 Layer height, right? (I have an MK3)
Re: Fixing Minor Issues - Adalinda Print Test
Thanks for the images!
Yes, the layer on mk2 is 0,2 mm. Foot seems to be the same yeah, the horizontal part of the belly i think looks a bit better on mine. But yeah, those gaps between layers i have are puzzling.
I think I'll try buying a new spool. Some of the issues I believe should be caused by the filament being out in the open all that time while it was unused and we had a pretty humid summer.
Re: Fixing Minor Issues - Adalinda Print Test
Was it in the open during the Fire? How serve was it? Do you think it may could have affected the filament?
You can also try to: unravel some of the filament to get to the deeper windings of the spool. Or you could try a smaller sample. Some resellers sell small 50g samples for cheap.
