Anyone design a decent filament monitor?

Post by Vandal968 » Fri Aug 05, 2016 8:07 pm

I'm using up a crummy old spool of white PLA (keeps cracking on the spool). I find myself going to the printer every ten minutes to see if it's time to swap to the next spool before it runs out, but of-course the last 1% of a spool lasts forever when you WANT it to run out. It made me wonder if anyone had come up with a decent filament monitor yet. Pausing the machine would be ideal, but just beeping would be good too since I'm usually in the neighborhood while printing.

cheers,

No solution here but I'm always blown away by the seemly infinite last 1%. It's such an odd annoyance.

Took 1 hr and 5mins for the final layer on spool. Need to write that down somewhere.....

I was thinking about running filament through electrical contacts that feed a simple peizo beeper. When end of the filament slips out of the contacts, the beeper would sound. Haven't worked on the actual design at all though.
