anyone make anything like that?
looking for something that will automatically pause a print when the filament is out.
Basically a sensor like this (which is shown on a lulzbot): https://www.amazon.com/Filament-Sensor-Printer-Detector-Monitor/dp/B016C8KSMS/ but instead of just sounding an alarm, it would actually pause the print and possibly also send an E-mail to yourself.
This could be connected to the PC running the printer, instead of the printer itself. Perhaps a seperate arduino.
I think the real question is how do you pause a print in Cura using an external signal. Is there a shortcut key.
