I got terd and wanted to take a break from the printer. My dad took over the project and these are pictures i took from his time wit it. We are using cura for slicing and repetier and k8200 printer. 3mm PLA with a 0.4 mm nozzle. We are also getting this black goop that is ruining our prints and our x axis sometimes moves when the printer starts printing a new layer. If you are using similar rig could you please share settings and experience.
