I use the Calibration file for the filament Calibration at the e3d sd card buth nothing happens... The bigbox is ok to print the benchy, so I don't know why calibration don't work. I selected extruder 0
The calibration script just tries to extrude 10mm of filament. If you did not heat up the extruder manually with the LCD it does nothing because the firmware is set to prevent cold extrusions. The min temp a hotend has to have is 180° C so that extrusion commands get executed...
