CR-10S Filament Guide
thingiverse
I've been enjoying my new CR-10S for a couple of months now but lately my prints have been garbage. After changing out the nozzle and then the hot end, I discovered the filament had worn a groove in the extruder arm. (See photo) I made this simple guide and my problem appears to be solved. I feed from the top and I guess it was putting too much strain on the arm. If you're using the filament out sensor, you may not have this problem. I have my sensor mounted in a remote location since it kept falling off the mount location.
