Completely guilty. When I built my cabinet, I didn’t think I’d have my plastic last this long…
You are spot on. Cabinet pics HERE. My spools are stored on a feed roll under the printer itself in a cabinet made from 80/20 extruded aluminum and 1/4" glass. The cabinet was made specifically with the intent of retaining the heat for ABS prints. I was focused on making the printer work well, and didn’t even consider what I’d be doing to my plastic… Looks like the cabinet is going to get an overhaul this winter (at least the bottom portion!). I need to work out some kinks in the feed system anyway (see what I did there? 
). I keep getting failed prints due to the plastic being too difficult to pull. I need to work out a better way to route / feed the plastic, and this will fit right in.
Thank you for the info - it’s very much appreciated!!
