CR-5 Pro H Filament Runout Sensor Not Working
I was printing a large print overnight, and the filament ran out towards the end. I woke up in the morning to see the head printing in the air, and the spool was empty. The filament sensor light was not lit. When I reloaded new filament, the light triggered and was showing correctly on the sensor itself. I am printing tethered with pronterface, because the SD card reader does not work on my unit.
It seems like the firmware does not recognize the filament sensor and doesn't trigger it to stop. The latest firmware on the site says: H V0.04 from 22 Feb. 2021. Do I need to modify this firmware file recognize the filament sensor? How do I do this, or fix this issue.
