I noticed a problem with the Runout sensor on the 3D print head
I placed a short length of filament in the 3D print head and started a test print to check if the the Run-out Sensor would work. I found it worked if the gcode file was loaded to the SM via WiFi and the run-out sensor did detect the lack of filament.
I did the test again using Luban and using the USB connection… the lack of filament was NOT detected and continued to fresh-air print.
I am using the latest Luban 3.1.1 and FW 18.104.22.168
