I went through all the prep steps. I can see when i do an extrude check that the heat nozzle will start melting the fillament. However, i tried a test calibration cube downloaded as an .stl file which i sliced and exported as a gcode file. I can pick the file on the KE control panel but it doesnt print and says printing complete fairly quickly.
do I have a bad print file?
Is there a simple gcode file to do a test print where I can verify if its working?
