Ender 3 Filament runout sensor and guide with bearing
Description
Thank you to blaiseb. He puts the Fusion360 file in the Zip. I put also my Fusion360 file in the Zip. So i want a sensor with led indicator. The red LED is on if the filament is out and the green one if the fillament is in. I used two old 3mm LEDs form a old computercase and two 100 Ohm resistance. At my MKS Gen L Board there are +5V,ground and signal. I used hot glue to fix the leds and the resistance. By the way. I have a problem that the unload and load length in the marlin 1.1.9 software did not work. The trick is to set the printer after the flash on factory defaults (M502) and then M500. The eeprom reload the new settings out of the firmware. Befor you reset the printer, write down the Z Offset setting. :-)
