I have my LR3 moving with cartesian kinematics defined, but still need to build my table to test the Y axis movement. In the marlin config, there dose seem to be some CNC specific features that enable different gcodes. I need to read more about it to see if I can adapt it to klipper macros. If you would like my printer.cfg and supporting includes, feel free to PM me.
I’ve used KIAUH on all of my klipper based machines. It’s an awesome wrapper script the installs all the needed components and their requirements, no OS images needed.
