The extruder is situated on the x-axle. The stresses has become significantly lower in the filament pipe and are regardless of the height of the x-axle. The cable to the motor is guided in the drag chain. You must use the holes in the original A2 plate for the attachment of motor holder. The original screws must be replaced by the M5x20mm screws.
I think this change is meaningful, as the quality of the print has improved significantly.
