Runout sensor #39

Open Nha-Krul opened 2 years ago

Nha-Krul commented 2 years ago

Hi, using the default options, command M412 not work and M119 doesn't show the Runout sensor status. Is this sensor working with other settings on Marling for Biqu B1 or only work printing with TFT's SD Card? I want to pass the runout singnal to Octoprint

Thanks

Biqu's implementation of the sensor has it such that it is connected to the TFT35 screen. The default firmware (to my knowledge) is also compiled without the FILAMENT_RUNOUT_SENSOR flag set (you can verify with M115 which should list "Cap: RUNOUT:1" if it is enabled). You can open it and move the FLD wire that is attached to the screen and move it to the E0DET port on the mainboard. You would also need updated firmware that has FILAMENT_RUNOUT_SENSOR enabled.
