BMCU_130 Steel Ball and Spring Clutch Version

This iteration consolidates the original BMCU-130 version with the 370 steel ball enhancement and a spring-loaded clutch, culminating in the [130 Steel Ball Version BMCU]

The model has undergone thorough testing and functions impeccably

The 130 steel ball variant necessitates additional components beyond those required for the original version

1. 182A gears increased from 8 pieces to 12 pieces

2. 5mm steel balls————————————4pcs

3. 0.3x4x5 springs———————————4pcs

4. 0.2x3.5x5 springs——————————4pcs

5. 62B shaft washers—————————(total of 40 pieces required)

6. M1.6x5mm screw for the triangular clutch plate———1pcs

7. Note: The positive and negative poles of the small board motor wires should be swapped; connect the board's positive to the motor's negative, and the board's negative to the motor's positive

Optimization One

The [130 Steel Ball Version BMCU] addresses numerous mechanical issues present in the original design (e.g., ① debris impeding the photoelectric sensor. ② excessively printed channel orifices or wear sustained from prolonged operation resulting in intermittent photoelectric contact. ③ anomalous photoelectric switch behavior when housed in transparent material enclosures. ④ erroneous filament detection attributable to photoelectric switch misalignment). All aforementioned concerns pertaining to the photoelectric sensor have been entirely obviated

Optimization Two

         The clutch mechanism has also been refined into a spring-loaded design, thereby negating the need for extensive adjustments during gear assembly

Optimization Three

The programming port and buttons for the base motherboard PCB have been judiciously relocated to the bottom surface, obviating the necessity of screw removal for subsequent firmware updates
