After printing with my Ultimaker 2+ for over two years, I started having issues with the material getting stuck in the coupler.
I pulled it out and looked at it. Sure enough it had some burn marks and some warping. Went online and all I could find were
PTFE couplers. I bought one, still have issues.
I cant find TFM couplers to purchase. Can someone point me to a site that sells them? hopefully by themselves without 200 dollars
worth of extra parts I don't need! ?
