UM2+ Filamt holder

GN1000 · July 6, 2016

I have just purchased my UM2+. I notice that the Filament holder positions the roll about 1 inch away from the rear of the machine. This results in the filament being pulled at a slight angle across the roll. Is this right? I was worried this could lead to tangling of the filament and when looked at photos and videos on the web othe UM2's seem to position the roll closer to the back where (preumably) the pull is straight from the roll.

Should I be concerned?

I had filament get dragged off a fresh spool twice and way too much friction with my favorite PLA for my liking, so I got something similar to IRobertI's Spool holder in a store. But before spending money, do check out his design here: https://www.youmagine.com/designs/low-friction-um2-spoolholder

There are a TON of cool spool holders out there on Thingiverse and Youmagine. I also agree that the friction is too high. The spool holder needs to be free spinning as far as I am concerned.

Probably the cheapest and fastest thing to do would be to go get a lazy susan from a kitchen store. Put it on the ground next to the printer. Put the spool on it. Put something "heavy" on it to keep it from lifting up off of the lazy susan.

This gives the filament a long distance to straighten out gradually and enter the feeder at a gentle angle.

Here is what I ended up with (not the lazy susan).
