I’m not the one saying “FreeCAD sucks”, its sprinkled throughout this entire post. My comment/questions was related to saying “okay so if FreeCAD “sucks” and fusion360 is pulling the rug on us, what else is out there that is comparable and as useful as fusion360”
Something else to check is your infill percentage. Make sure you don’t have it at 100% (unless you absolutely need to build something completely solid). Another thing to check is your print speed. Too low and it will take a decade to print something simple. Too fast and it cause your print to fail. At this point we will all be throwing spaghetti against the wall. Can you share a screenshot of your settings?
