Is it possible to have a custom kinematic in planetcnc? Looking at the most recent user manual and digging through the settings it looks like it isn't possible, but used to be? H-bot and delta are mentioned. I was expecting an entry for Kinematic under Motion settings.

All I am looking to do is correct for out-of-square (XY plane), so close to the trivial Cartesian kinematic. The machine is too stiff to gantry square.
