98U Base Controller

A base controller solution adaptable to various 98MMU-type grinders on the market (with rain U as the original, other XXUs being imitations), offering improved concealment and streamlined wiring for tidy placement compared to the original square box controller.

Verified on a Times Superlative servo motor using 5V pulse control; theoretically applicable to other servo motors, though adjustments and independent research are required, and guidance is unavailable.

A custom controller, enabling multi-stage speed control and timed grinding shutdown, is also needed; purchase link below.

Parameter Writing

Write parameters to the chip using the method below; “donE” indicates success, followed by a 30-second power cycle for activation.

(Diagram frequently omitted; consult the instruction manual for details)

WX10 Controller Setup

• PE select F1
• P1 = 4
• P3 = 0
• P5 = 3
• P7 = 800 (grinding speed)
• P8 = 8 (grinding time)
• P9 = 1500 (powder dispensing speed)
• P10 = 3 (powder dispensing time)

After connecting, start the controller and verify if the control speed matches the servo controller.
