MANUAL_STEPPER Robot Arm

I am building a THOR 6 axis robot arm. It has no extruder and kinematics:none because there is no xyz. I would like to specify only six MANUAL_STEPPERs in the config. Is this allowed by klipper?

I am getting this in klippy.log since I deleted stepper_z and the rest of the steppers:

Error: Option ‘position_max’ in section ‘stepper_z’ must be specified
