Joint 0,1 collide

Solution: Swap joint 0 motor position with gear, replace ring with gear, increase bearing sheet size.

joint 0 redesign benefits

• Luckily the common gear is half as expensive as the ring|internal gear.
• Also nice is that the bearing plastic sheet is obsolete now as the gear is made from plastics which also reduces friction with the pinion gear at the motor.
• As the motor becomes static now electricity supply wire twisting is prevented in the new design, too.
• Another positive side effect is that now there is enough space for the bigger NEMA34 compatible motor, resulting in 5 times as much torque which may be required to overcome joint0 static friction despite grease or oil bath in the .0006 clearance.
• Allows to use module 2 instead module 1.5 tooth size, resulting in a more rigid design. This makes it possible to mount an even bigger motor, i.e. maybe even allow to control yaw of spider leg variant this way.
