Grounding ABS

[victor 0]

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

If your filament is grinding in the feeder and thusly not feeding, it is probably a tension thing.

If your printcore is not heating up enough to properly melt the plastic, it may be having to use too much force to get the filament through.

If your feeder is too loose or tight, it can grind the filament. Here is one link for info on this.

Since you say it is a two year old machine, then I took a guess, but the idea remains the same as far as I have found.

Be aware that different makes and colors of materials can have slightly different properties.
