How do you handle end of filament detection?
Do you end up with lots of unused wasted filament in spools to avoid running out of filament?
I am new to Mendel90 and almost finished printing with my first 1 kg PLA spool.
My 1st 3D printer is a 3DWOX that has a filament counter and a microchip inside filament cartridge to estimate end of the filament.
I do not see any filament sensor for Mendel90.
However, I see such sensor available today.https://www.thingiverse.com/thing:1698397https://www.aliexpress.com/item/3DSWAY-3D-Printer-Part-Material-detection-module-for-Lerdge-Board-1-75mm-3-0mm-filament-detecting/32796458815.html
Would that work with Marlin firmware to enable automatic pause? If yes, which pin to connect?
I noticed this feature for Marlin was discussed 2 years ago. I wonder what is the current status.http://forums.reprap.org/read.php?1,599640,606852
Please advise. Thanks.
