Extruding Problem

[cncartist]

Have you bought any of the PTFE tubing you see on Amazon and sites like that to use for replacements?
I have been looking at them I have not decided yet. The prices are great compared to buying them pre-cut.

Yes, I did purchase 6 feet but unfortunately it seemed to be ~0.1mm oversized. It was so slight that I could jam it into the feed tube and I wasn't fond of that technique. I put the cut pieces aside for now and will post process them in the near future (rainy day project).

I didn't want to mess around with yanking a seized PTFE tube out with pliers and chose to pickup the ~$20 QIDI 4 nozzle + 4 ptfe tube kit on ebay. Three of the nozzles and tubes have been utilized in the past 1200 hours of printing and I was fortunate to have my first nozzle last to over 1000 hours.
