BMCU Optimized Version with Adjustable Photoelectric Sensor

This model incorporates the following improvements upon the open-source version:

1. An additional screw hole has been added to the motor to reduce vibration.

2. The photoelectric component is adjustable; the model includes two parts with photoelectric holes—one at the standard height and another lowered by 0.3mm—allowing for selection based on specific needs.

3. The triangular swing arm has been optimized. The standard model's swing arm interfered with the motor worm gear during retraction; this issue has been resolved.

Additionally, for beginners, print settings are crucial. This model pre-configures which parts require supports and which do not, ensuring a successful first print.
