Before diving into the adaptor and driver, it’s essential to understand Weihong’s ecosystem. Weihong (a brand of Nanjing Weihong Electronic Technology Co., Ltd.) produces PC-based CNC controllers. Unlike standalone controllers (like Mach3 or LinuxCNC on generic hardware), Weihong uses a hybrid approach:
| Parameter | Value | Rationale | | :--- | :--- | :--- | | | 1/16 or 1/32 | Reduces low-speed resonance in 3D contours. | | Pulse Frequency | 150 kHz | Stable through most adapter opto-couplers. | | Acceleration | 200 mm/s² | Prevents mechanical shudder on small arcs. | | Arc interpolation mode | Use "NURBS" or "R" mode (if CAM supports) | Reduces G-code size by 90% vs. linear segments. | | Driver current | 70% of rated | Lowers motor heating during long 3D runs (hours). | weihong cnc adaptor pcimc 3d driver work
