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!
