I’m having trouble with a print having a line around the whole layer and also not printing properly on a surface Any info will help has been driving me crazy trying to figure it out here are all the settings Im using. Its Overture Petg.
Hello, I’ve been printing things with Overture PETG for quite a while, never had this kind of issue. My guess is, this is an artefact from layer expansion which would make sense since the line appear on the same layer as the big flat surface.
I’d advise you to change your wall printing order to Outer/Inner, which should help mitigate the problem. Under the quality tab, scroll to the bottom and you’ll see that option.

This is an easy one. There are two issues but first, your filament isn’t properly calibrated.
One can clearly see that the line you are witnessing happens at the boundary of where the floor of the model occurs. It may help to understand that this is caused because the floor has more mass and will shrink at a different rates of cooling causing such lines.
There are two remedies. First is of course to manually calibrate your filament. You could take a shortcut and simply cut the speed by 50% using the quite mode in the device menu but that’s will be at the sacrifice of throughput.
The second option if you don’t want to take the time to calibrate the filament is to overcompensate for shrinkage in the walls by increasing the outer wall layer. Also consider changing the wall order from the default of inner/outer to outer/inner which will have a dramatic affect on the order that the walls cool down.
Here’s where you can see evidence of what I am referring to. The slipping of the belt is the least likely cause of the rippling. One should exhaust calibration options before tinkering with the belts which might risk only making things worse. On this case, I might pursue max flowrate calibration which Orca Slicer has but is not present in Bambu Studio. If you don’t already have it, consider loading Orca Slicer on your system, it is forked from Bambu Studio so it’s interchangeable and you can use both programs at the same time. Orca however, has many more features.
