How do you check the configuration file? For example, in the case of delta, adding the stepper_x section will result in an error.
You have to stick closely to the documentation.
With Delta you have stepper a, b and c :
I would like to add new kinematics. For example, suppose I create a copy kinematics called kin_copy.py, which is a copy of kin_delta.py. In this case, how are the section restrictions imposed? I would like to edit this limit (so that stepper_x cannot be selected with delta).
