Can anyone help please. I am new to this, so I apologise for my knowledge base. I have just bought a Reprap Prusa i3 Impresora 3D DIY kit LCD MK8. I have built it and everything is working, including Cura from a pc running windows 7 64bit except the filament feed. There is no PLA coming out of the print nozzle. I have checked the nozzle and it is clear as is the heat tube in the extruder module.by malc - Reprappers
