I think you're right. We installed the PVA spool back when we first got the a machine on Oct. 26 2022 and this was the first use of it on Nov. 10 2022. The facility itself is somewhat humidity controlled but not nearly enough to make a difference at the location of the printer as it is in a "closed" room on the second floor on a production floor with no direct air ducting. We printed another 2 in a different orientation, with glue and the adhesion rafts. MUCH better print! It did peel off from the bed a lot easier though so I'm not sure if I am doing the glue correctly. I heated the bed to 60c as you recommended, then used the glue stick and wiped the entire surface with a wet paper towel until a thin uniform layer was formed and immediately started the print (which purged the nozzles and did the whole start up with a new filament. Didn't actually print for about 5 more minutes). Is that correct? Also, we are still seeing some burnt filament on the print itself leaving small cracks/voids in the outer wall of the print. I changed it to "engineering" at 0.1mm as you recommended with 100% fill as the part will be subject to about 50psi of dispensing forces. Are these features common with PC or is this caused by using dual extrusion? We did not see these features printing with no support on tough PLA. Thank you for your help and time!

Hello gr5! Thank you very much for the quick reply! I wasn't aware that the glue had to be THAT thin but it makes a lot more sense now. I have been taking the glue stick directly onto the glass and then leaving that as is, making sure as I apply it there's no globs or anything. I will definitely try that now! I also did not know that layer height or the modes changed the tolerancing. Honestly this is the very first 3D printer I have ever even seen in person so I have absolutely no idea what any of these settings are or do. I assumed that those preset profiles were for layer height only. For question 3, I circled the "top surface" I was referring to. Basically the layer the printer just completed/printing now. This picture is taken almost directly across the surface and has a bunch of little bumps and dots on it. I understand now that these are meant to be seen and normal on the priming tower, but is this normal as well inside the support areas? Thank you again for your guidance and time!

I recently purchased the S5 Pro Bundle and began running some prototype parts. In the pictures you can see most of the issues. This print is using Ultimakers Natural PVA for support (P/N 9731) and Transparent PCA (P/N 1640). Below are the issues I see and would greatly appreciate any help, I did try searching for these issues but as I am not entirely too sure what the issues are called I was unable to find anything clear (settings based on material). I have also attached the project file to assist? Not sure if this saves current settings or if the model is included but wanted to include it as well just in case. I am printing on extra fine settings "0.06" using Cura Enterprise. After the support/ part material finishes the layer and is switched, there is oozing on both nozzles that either fall off onto the glass bed or get stuck to the side of the part / purge tower. You can see all the FOD on the glass and on the side of the tower and part. Delaminating from glass is a big issue and causing the part to shake when printing. This part in the picture did NOT have a raft on it but did have the glue that came with it. Does the heated bed weaken the glue? On a past part which had a large flat bottom (2.5" x 6"), the corners lifted worse with glue than a raft, but even with no glue and the raft it still lifted. This tends to only happen after many layers of the actual material and not with the support? The top surface or last printed layer has a bunch of bumps or blobs on it. I believe these are in the support material and do not seem to appear in the part material. It's hard to see, but there are many pieces of filament that are burnt in color? Not sure what causes that but it seems like that shouldn't happen. Is there a way to calculate shrinking? I tried printing a reference gauge and noticed that is was about 0.012" shorter across a 6" length. I really am looking for help with the settings for each material or for the print that I can save somehow in the software / printer so after I set everything once it will stay set that way. Also, any advise for future prints such as orientation and printing threads would be amazing as well! :) UMS5_Sausage Pack to 0.25in NPT.3mf
