I noticed this issue when printing a magnetic boot for Milwaukee batteries, right where the bottom meets the walls (where it starts to become hollow on the inside) it’s like it’s shifting the outer wall out by .5mm. In the slicer it looks perfectly fine, and I was able to duplicate the issue by making a cube with a negative cube inside it in Bambu studio to rule out a model issue.

In the picture, the line on the outer wall of the print shouldn’t be there and the nothing i can see in the slicer shows a reason for it to be there. It’s perfectly fine on the inside of the box as well.

Wondering if someone might help me figure out what’s going on with my prints, it’s a H2c printer with bambulabs abs basic filament. Basically on any kind of flat print it seems fine but any time there is any kind of overhang or curved/slanted feature it ends up looking something like this.

These pictures are with chamber temp set to 65, print bed 100 and nozzle set to 260 and on the default 0.20mm standard profile with the only settings changed being 4 walls and 3d honeycomb infill using a .4mm nozzle on the right side of the tool head. The issue gets significantly better with the chamber temp set to 0 and the rest of the temps kept the same.

The only thing I can come up with is lack of cooling but the cooling settings are all stock and look correct and I ’ve not had an issue with this before on ether of my Creality k2 plus machines nor my voron printer with abs and similar temp settings, so not sure why the H2c would be having issues with it.
