Note: Differential signals are preferred for long distances. Some Weihong adaptors convert differential to single-ended. Check your driver’s input type.

Example: X moves 1000 steps, Y moves 500 steps, Z moves 250 steps – all in 0.1 seconds.

Operating the PCIMC-3D involves an interconnected chain of distinct hardware components:

→ Measure 0–10V output from adaptor spindle terminal. → Configure M3/M4 commands in software (e.g., M3 S12000).

Test with low speed

Before examining the adaptor and driver, one must understand Weihong’s philosophy. Unlike USB-to-parallel-port converters or Arduino-based GRBL systems, Weihong uses . These cards offload real-time trajectory calculations from the PC’s CPU to a dedicated DSP (Digital Signal Processor). The result? Smoother stepper/servo movement, higher frequency pulse output (up to 1MHz or more), and no Windows latency glitches.
