I have been printing with a few different filaments with success. Lately, I have been having problems printing with ABS. I have had poor adhesion between layers and have had things all but crumble when squeezed. Here’s an example of one piece I printed. The top of the part is the first layer. Not sure what happened or what changed. Any help you can give would be greatly appreciated. I have tried turning the print cooling off based on some of what I’ve read on here.
