Hi I am running an MK9 with a low friction nozzle. I just started having problems with a jam. So I took it apart and clean and soaked the nozzle and nozzle neck in acetone for 2 days. The pieces we clean and I re calibrated the extruder rate and replaced the nozzle neck and experienced a new problem. The first 50 layers print fine and after that I have spotty layers like my extruder is randomly extruding. I check temperatures and they are not changing. I am stumped at this point. Anyone have any ideas?
