Printer feeding problem with new parts

Recommended Posts

Hello, I am using my um2 since more than 2 years now. Everything whent mostly right until a couple of weeks. I am not abble to feed anymore, the filament seems to stuck between the teflon coupler and the nuzzle. I’m used to regular maintenance and atomic pull and teflon coupler replacement, no need to explain ?. Due to the problem I change the tube, coupler and nuzzle. I also dissasemble the olsson block and feeder for clean up and inspection, but nothing. 

 

Note: when I’m feeding by hand the filament is having a hard time finding the nozzle but once it’s there the flow is normal. When I tried to feed normaly, the filament never reach the nozzle.

 

Could it be the ollson block end of life?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
