Filament monitor for FlashForge printers

[toybuilder]

Its worth mentioning that your print may loosen from the build platform when it cools.

Yes. I did point that out earlier - for build plates that tend to release upon cooling, if you have cool-on-pause enabled, it will cause the print to come off. If you use heated pause, the part won't come off, but you may still have shrinking of parts, enough to show a seam line.

With my setup, pausing the printer for more than 20-30 min would kill the print anyway, and for 90 bucks (dual extruder) there is very little ROI versus a simple end of spool sensor connected to a MySensor.org sensor to send notifications. The price has to come way down for it to work for my setup.

Well, the Tunell monitor is intended for uses where more sophisticated monitoring is desired -- clogged nozzle, knotted up spools, filament diamter way over or under size causing feeding problems, filament that broke inside the feed tube, etc. UPDATE: And, of course, when the filament has run out.

For anyone that wants a simple out-of-filament detection, you could just wire a microswitch to the printer -- that would be the least expensive way to go.
