Re: Detachable Spool Holder

I'm building new printer cabinets for work which have an overhead filament rack for holding those giant 5Kg spools that Gizmo Dork sells too. We have a big ShopBot and can crank out 20 cabinets in just a few days. I think one of those spools would let us print continually all week without one filame...

Detachable Spool Holder

I'm working on compacting our M2 farm at work and came up with this detachable spool holder that lets you place printers closer to each other by removing the extra space that has to be allowed for sliding the spool on and off. This would also be useful if you were putting your printer in a box that ...

Re: Filament Empty Alarm

I was concerned about the filament dragging across anything plastic on the switch, since thousands of feet of filament being pulled over that could wear a divot in it and cause it to eventually fail. The switches with brass wheels are kind of hard to find on amazon, but here's the one I managed to l...

Re: Filament Empty Alarm

If I think there's a risk of running out of filament, I weigh the spool before I start. I have saved an empty spool from each filament supplier I use for a tare reference. The weight estimates from S3D seem to be pretty much spot-on. I use 1.05 for ABS density and 1.25 for PETG. I've run prints fro...

Re: Filament Empty Alarm

That all sounds possible, but I'm not motivated enough to do it. I can catch 80% of my run-outs with just the buzzer and still have time to feed in a new spool. It's the overnight run-outs or away from home ones that will still get me. It has the same loudness as a smoke detector alarm, so it might ...

Filament Empty Alarm

After having so many prints ruined from filament run-outs, including while I was even sitting in the same room and did not catch it in time, I finally got around to making a simple alarm that can be heard anywhere in the house when a spool runs empty. The alarm can of course be turned off so that it...

Re: Hatchbox PETG - Looking Good!

80 works too, looks like that is the low end cutoff for adhesion. The Rave 4x Mega hairspray works too. I like that you can squirt the non-aerosol spray on a hot plate and wipe it around without it gumming up the way ABS slurry would if you tried that. That allows recoating without waiting for the p...

Re: Hatchbox PETG - Looking Good!

Thanks, that was it. I'm printing at 100 right now and it is working, so I'll back it off to 80 on the next one and see how that goes. I have a feeling the other hairspray I was using will also work with the correct bed temp (Rave 4X Mega non aerosol).

Re: Hatchbox PETG - Looking Good!

pyro why not just pick up the the plate, mist it and drop it back on the printer? only takes a second since the plate just sits there. a squirt bottle and napkin isn't a very controlled way to apply the stuff and sounds like taking a 2 sec job and turning it into a mess. ;) I just tried this with t...

Re: Filament Splicer

I just touch both ends to a soldering iron and then stick them together and quickly press them in the block. The block needs to be cold so that it solidifies quickly. The strands can be moved through the brass tubes and the ends will be pretty aligned so all you have to do is slide one piece while h...
