K2 Plus: when using this app and slicing a model with the built in slicer, I try to print but it says they can’t find my printer and want me to set it up. However, things that have just the print option print just fine. Why is this? Also, is there a way to have only k2 plus compatible models show on the app since that is the printer I have? So many disappointments when I find a model I want and there is not k2 option.
