Thích hợp NC-UV0609PEIII-II Y-axis motor replacement​ is required when the flatbed moves erratically, fails to initialize, or triggers platen limit sensor errors (Error 121/122). The Y-axis motor—mounted at the rear of the machine as the “Platform motor”—drives the flatbed back and forth under the control of the main board. A failing motor causes positioning drift, print misregistration, and platform faults. Replacing it restores accurate, stable bed movement. Thực hiện theo các bước dưới đây một cách cẩn thận.

Sự chuẩn bị

Tắt nguồn máy in và ngắt kết nối cáp nguồn. Mang găng tay chống tĩnh điện. Clear the workspace and ensure good lighting. Bạn sẽ cần: a new compatible Y-axis stepper motor, hex key set, Phillips screwdriver, needle-nose pliers, and a torque wrench (không bắt buộc).

Removing the Old Motor

Open the rear access panel to expose the Y-axis drive assembly. The platform motor driving wheel and driven wheel are clearly identified on the rear view of the machine. Disconnect the motor signal and power cable from the main board. Loosen the coupling or belt tensioner connecting the motor to the platform drive. Remove the mounting bolts and carefully extract the old motor, noting its orientation and spacer placement.

Installing the New Motor

Position the new motor with the same orientation and spacers. Tighten the mounting bolts evenly. Reconnect the coupling or adjust belt tension to 5–8 mm deflection under moderate finger pressure. Route and plug the motor cable back into the main board, đảm bảo các đầu nối khóa chắc chắn. Secure all cable ties away from moving parts.

Kiểm tra và hiệu chuẩn

Kết nối lại nguồn và bật máy in. Run the platen initialization routine from the control panel. Observe the flatbed moving forward and backward smoothly without hitting limits prematurely. If Error 121 hoặc 122 appears, recheck the platen limit sensor cable and sensor position. Print a test pattern with fine horizontal lines to verify Y-axis registration. Once the platform moves accurately and prints are aligned, NC-UV0609PEIII-II đã sẵn sàng để sản xuất.

Post-Replacement Care

Monitor platform movement for the first hour. Re-tighten couplings after 8 hours of operation. Periodically inspect the platen limit sensor and cable for dust or looseness to prevent recurring faults.
