So to start off, I've been having problems printing specific files on my CR-10S lately. For the most part, my printer has been working like a champ, and I recently finished off a large project with no major issues. Recently I've been working on my next project, which are casts for my lower legs (with the intention of carving them out after wards to use as stencils for bodypaint for cosplay. I'd do the detailing first before printing, but the designs are fairly complicated, and I'm not quite sure how to design those to cut onto a curved surface, but I know how to carve it out with my soldering iron after the fact). I've failed printing these three times now, and I'm really having a hard time figuring out what the issue is.

First Two Failure Attempts

The first attempt I'm relatively sure was either a feed issue, or a bed adhesion issue, or some combination of both. I'd moved my printer onto a new shelf after finishing my last project, and had changed where the filament was feeding in from in relation to where the printer sits to try and make things fit nicely. Probably a bad idea, but I printed a benchy in the new setup without issue, so I had no reason to worry. I usually just use gluesticks for bed adhesion, with no issues in the past as well.

For the second attempt I thought the first one was *just* an adhesion issue, so after I'd cleaned the mess from the first failure, I rotated the STLs 90 degrees so they were laying longways on the print bed (I wanted to avoid that because it just uses so much more filament for supports). This one when I came back to the printer thankfully it had clogged instead of spitting out filament spagetti style the whole time. I took apart the hotend to clean it, and ended up having to remove a clog from the bowden tube. After cleaning the printer I printed another test benchy, again with no issues. (and a few other things just for fun - it seems I'm ONLY running into issues trying to print these stencils)

Now for the third attempt (not pictured) I had returned my printer to it' original orientation - printer facing forward with the control box and filament feeding from the left side of the printer. To combat what *may* have been an adhesion issue, since the parts are relatively thin, I also chose to print on a raft - with the STLs again oriented vertically. I opened a brand new roll of filament just in case the one I'd been using had been sitting too long and accumulated moisture. I re-leveled the print bed. Nothing could possibly go wrong. The raft printed beautifully, good even coverage and perfect adhesion to the bed, but the very first layer of the actual STL did not adhere to the raft - not keeping its shape and disconnected from the raft entirely when I ran my finger across to check.

​

I was worried that there were errors in the STL files themselves, so I ran them through a repair tool online. The repair tool online found no errors or anything that needed to be corrected.

​

I've been printing in PLA, the specific type of filament is Pro PLA by 3D Fuel (no issues with it during the larger projcet, I was using the same brand). I believe I'm using largely default settings on Cura - but I'll link those below just in case.

Please, if anyone has any help or suggestions please let me know. I feel like I've tried everything and I'm at my wits end trying to make these pieces print properly.
