Hi. I'm trying to customize a printer profile for my Velleman K8400, but I cant figure out how. The K8400 has the XYZ home position in the far right corner, but cura has it in the front left corner. How/where can I change this in cura? I basically wan to turn the bed 180° in cura. I can't find any settings for this in the K8400 or fdmprinter definition files. Another problem is that the manual XYZ printer controls are reversed. Where do I change that? Any help is appreciated. Best regards, Lage
