Reverse Grinding?

Recommended Posts

Hey guys,

I have started getting problems when changing filaments where it will just not reverse the filament but instead grind it down on the spot. I cleaned out the mechanism and it feeds in just fine.

Any ideas? its a UM2

Change your pfte coupler or get used to printing using my guide in how to print with a damaged pfte coupler. Search for it in you tube.

Here you go. Your gonna be taking the bowden out after every print.

 

Also make sure you do atomic pulls too. I got a vid for that as well.

So actually I just bought a pfte coupler from ORsen but not got it yet. Is that my problem? Sometimes it works a dream other times it doesnt.

If thats the issue thats an easy problem to fix when it turns up :)

My pfte coupler hasnt lasted too long dissapointingly then, maybe only 800 hours or so, and im only printing PLA. I heard someone else saying they should last at least 1000+

I dont really know your exact problem, but it was the coupler for me when that started happening to me. i printed about 10 months on my first one but i really did push it till it totally died and i could physically print no more!

    • "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.
