Printer extruding filament when no print is happening
I have a Monoprice Maker Select 3d printer (which is a rebranded Wanhao Duplicator i3). I just set up Repetier-Server on a Raspberry Pi 3 (not using the pre-built image), and it has a strange problem. At some times when it is not printing, it extrudes filament. Why is this happening and how can I stop it?
