I have seen some nice plexy DIY covers that would be a better investment than the metal 'deluxe' cover plus load filament above extruder like some delta printers did. saves floor space too

Here is a picture of how I have mine set up.  Even with the fullest rolls It never jumps the spool even when I have three on there and pull from the outside spool.

Thanks, that looks simple. I'm now thinking of printing something similar..

I use a filament dehydrator. It is just a box with a lid made of polycarbonate that holds my reel the way I want so it does not uncoil and stays dry.( small bags of dessicant inside)  A small hole in the lid and some half hoops on each side to hole the reel off the bottom. Simple and fixes two problems for me.

The guide is mounted so that it's away from the printer, with about a foot of filament b/w the guide and the entry to the case. The hole in the case is centered at the top of the rear panel.

I've had many successful prints since I started using the guide, and I check the filament before each print, but last night it messed up. Just weird..

I printed a couple of the 2nd ones and have been using them since the last post here. Seemed to do the trick

I had about 2hrs worth of printing of the remaining parts for my carriage upgrades, and the filament managed to hop off and get caught up, which ruined the print.

Dammit!!! What the hell can be done to prevent this? It seems some kind of constant tension on the spool would solve it. I think what's happening is that the slack in large Y-axis movements back towards the rear can sometimes be enough to allow the filament to jump off the sides of the spool.
