Hello fellow ultimakers,
Recently i switched from PLA to ABS after 2 years. I absolutely love ABS and how you can vapour-smooth it with acetone fumes. But i have a problem that only happens with ABS. Once a print is finished somehow the filament is ground. And i have to change material to print another object. So i print something without a problem and the printhead goes back to it's corner. But when i try to print again there is no extrusion because the feeder wheel has ground into the filament. I think this is very weird because after i change the material it prints without a problem untill i print another thing. I hope you guys have a solutio for me.
Kind regards,
Victor
