Compatibility Warning : Do not confuse PCIMC 3D 67 Top with the older PCIMC-3 (which lacks 6-axis interpolation) or the PCIMC-4 (USB version with higher latency). Also, this card is not compatible with Mach3, LinuxCNC, or EdingCNC — it works exclusively with Weihong’s proprietary software.
If your spindle turns on but your X-axis won't move, or your tool path stutters during 3D carving, your adaptor might be the culprit. Here are the top three failure modes:
The "67 Top" designation unlocks advanced 3D functions: weihong cnc adaptor pcimc 3d 67 top
Pro tip: For 3D lithophane or relief carving, set the LookAhead value to 200 and CornerTolerance to 0.01mm. The PCIMC 3D 67 Top will maintain 8000 mm/min while holding 20-micron accuracy.
While other motion controllers (e.g., Mach3 via parallel port, DSP handhelds, or Ethernet SmoothStepper) exist, the Weihong solution holds unique advantages:
For workshops already using Weihong software, this adaptor is the only certified path to reliable 6-axis 3D work.
Incorrect installation is the #1 cause of "Adaptor not found" errors. Follow this guide carefully. For workshops already using Weihong software
Despite the "3D" in its name, this is not a 3D printer part. In the Weihong ecosystem, the PCIMC (PCI Motion Control) series adaptors act as the intermediary between your computer’s PCI slot and the machine’s servo drivers.
The "3D 67 Top" variant specifically refers to a high-density breakout board or terminal adaptor. It is designed for:
During complex 3D machining, the machine cuts a circle that ends up as an oval. This often points to a failing optocoupler on the PCIMC board, resulting in missed step pulses.
