What Settings Should I Be Looking At?
Hello all,
I finally got my Mk3S+ going and on my first print, it came out half crappy. I did all the calibrations after setup including the Wizard. I did the first layer calibration that I found on this site that prints about a 3" x 3" square to give you more time to adjust the Live Z. I got it to what I thought looked good. I think it was ~-1.055 or something like that. Anyhow, this is how my first print came out using PLA. On the top, you can see the 5 holes are totally ugly, and for some reason I got layer separation in the other photos, along with some weird bumps. I used organic support (same material), which was build plate only. Can anyone explain the results and offer any recommendations? I use a Ultimaker S7 at work, which is basically start and walk away, and I know the Prusa is capable of the same when set correctly, but I am at a loss. How can some areas look good, and some look so bad? FYI, all of this was sliced in the latest Prusa Slicer. 🙂 Not sure if this has anything to do with it, but I have my printer in my shop, which gets pretty cold. I have to heat the extruder with a heat gun to get past the low temp alarm. I do have it in one of those collapsible enclosures that you get on Amazon, so it should stay a little warm, or should I open it, since this is PLA?
EDIT: After looking at the photos closer, it looks as if the print rotated a couple of degrees midway through the print. If you look at the 3rd and 4th photo, you can see that the notch seems to have shifted. And the 4th picture also seems to have extra material on the left side of the notch, and missing material on the right side.
Thanks in advance,
Mike

You appear to have some minor warping there which may have caused a head crash and consequent layer shift - if so what was the cause..?
It might have been the cold air you mentiond but let's check bed adhesion first. Please show us the underside of the failed print.
Cheerio,

Hi. Thank you for the reply. Here is a photo of the bottom section. Some of the organic support stuck better to the build plate than others... 🙂 There is definitely some separation in the bottom-right and top-left corners of the photo...
There are issues starting from the first layer ... please run the built-in first layer calibration routine and show us the result *on the build sheet*.
Cheerio,

Hi Diem,
Sorry for the delay. I will do that when I get home... I also want to record something I was noticing with I was printing out those other Live Z adjustment prints that others have created. I will update when I am done.
Thanks again!!!

And while you are at it, you might want to start with a smaller, less complicated print to work out the initial problems before pinting big things that require supports and special attention.
If at first you don't succeed, skydiving is not for you.
Find out why this is pinned in the general section!

Sorry for the delay. Ok, so I did a factory reset just to eliminate any odd issues. I am running the latest firmware. I obviously had to go through the whole calibration wizard. Attached are photos of the calibration print as well as the Prusa test print. So, I am noticing something really weird. On the Live Z calibration print, the Y axis pauses for a split second on the return from each direction. The red squares on the images below are where it does this. When printing the Prusa Logo, as printing at an angle, the head totally jogs to the side like a lightning bolt. After the print was done, I took a photo of the bottom, and you can actually see where it zigzags... I am not sure what is causing this... I attached some videos of the Y Axis behavior...
