I’m experiencing a bad layer adhesion problem that started happening like 2 days ago, I’ve calibrated the printer many times, but nothing seems to help.
I’ve noticed this only happens when printing fully filled objects in wide areas, the walls are being printed perfectly.
It looks like the bad layer is being printed in the air, a bit higher than it should be, what setting could affect this?
Your build plate shows signs of contamination. Take Dawn dishwashing liquid(Sold under the Fairy Liquid brand in the EU) and smear a generous amount by hand on the plate. Take very hot tap water from your sink and blast it till all the soap runs off then repeat. No scrubbing should be necessary despite what you may read elsewhere unless you contaminated the plate with a lubricant for your printer… it happens. If that’s the case, you’ll have to use more aggressive measures. 100% Isopropyl Alcohol(IPA) which can be found only online or at a industrial supply house can sometimes be a good tool for in-between cleanings. The drugstore rubbing alcohol is typically no more than 75%.
To verify that the bed is clean, right-click and select Cube Primitive. Resize it to 200x200x0.2mm. This will create a single layer sheet that will readily reveal contamination spots without using a lot of filament. Here’s an example of what that looks like with a deliberately contaminated plate showing fingerprints. This is not obvious with a textured plate.
OK. I missed that part. For layer adhesion between layers, have you performed a temperature tower test to ensure that you have selected the optimal temp?
Here’s a quick list of things to try in the meantime.
Check when the part cooling fan comes on. Try changing it in the filament profile.
You could also just bump up the filament temp just to see if there is a difference.
You said you dried your filament but did you weigh it before and after to measure just how much moisture was present or removed?
Can you reproduce this problem with a small cut of the model? This will only act as a troubleshooting technique to create a smaller test model for quicker and less filament wasting trial and error diagnostics.
Have you tried to rotate the model on the Z-Axis to see if orientation affects the location of the separation?
I’ve reset to default machine G-code plus increased the temperature to 240 degrees and now it prints the layers perfectly fine. Not sure what exactly fixed the issue though, will have to print some extra tests.
Thanks for all these troubleshooting steps, will definitely try them in the future.
