Note to self: Don't buy 2lb spools of ABS again Well I got an order of 3 new colors in today I normally buy 1lb spools but I wanted red and the place I buy from only had 2lb red in stock so I bought it. Designed a large fume extractor hood that needs support (6-7 hour print) set it off and went to bed (next room, left door open) after a little over 2 hours I heard what sounded like belts slipping (tooth chatter) I ran out to find about 12 feet of red ABS filament wrapped around my entire machine. It came off the spool I believe due to it being so full and just tied everything up in a knot. I just unspooled a bunch of it (until it quite springing off on it's own) and have to clean up the glass and start over. Is there some method of keeping spools from unwinding like this? https://reprap.org/forum/read.php?1,165117,165117#msg-165117 Sun, 07 Jun 2026 01:15:31 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,165117,166334#msg-166334 Re: Note to self: Don't buy 2lb spools of ABS again https://reprap.org/forum/read.php?1,165117,166334#msg-166334 Prusa-Top Spool Mount with tightly wound 1kg spools.

I've had zero tangles with the big spool on the back using this method. The front one can tangle itself on rare occasions, but I usually catch it when I check in on the printer every couple hours or so.

you essentially put piece of threaded rod through the centre with big cones and mount the spool on that, then instead of using bearings for it to ride on you simply use washers]]> thejollygrimreaper General Fri, 09 Nov 2012 04:26:06 -0500 https://reprap.org/forum/read.php?1,165117,165117#msg-165117 Note to self: Don't buy 2lb spools of ABS again https://reprap.org/forum/read.php?1,165117,165117#msg-165117
