Host PC ↔ Motion card (PCIMC/Weihong)

Point the Windows "Found New Hardware Wizard" to the Drivers folder inside your NcStudio installation directory. Look for files like Pcimc3d.sys or Pcimc3d.inf . ⚙️ Step 3: Verifying the Connection

Happy machining – in full 3D!

Assumptions (reasonable defaults): a PC with an internal Weihong/PCIMC motion card, stepper drivers, and up to 4 axes.

Insert the PCIMC control card firmly into an available PCI slot on the motherboard.

Do not rewrite your G-code. Open the parameter settings inside NcStudio, locate the axis direction parameters, and toggle the value (e.g., change 1 to -1 or change True to False ).

Motor stalling/vibration

On Windows 10/11, you may need to disable driver signature enforcement for the legacy drivers to function.

Power down your computer and disconnect the main power cable. Open the computer case to expose the motherboard layout.

Power down the PC, insert the PCIMC-3D card into the motherboard's PCI slot, and reboot. Windows will prompt that "New Hardware has been detected." Navigate to .

: The adapter supplies steady pulse streams (typically up to 160 KBit/s) to command step or servo motor drivers with minimal jitter.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | “No PCI-MC found” | 3D driver not installed or blocked by Windows driver signature | Disable driver signature enforcement (Win 7/10) or reinstall driver from Weihong CD | | Motors don’t move | Adaptor not powered or loose ribbon cable | Check +5V/+24V on adaptor; reseat cable between PCI-MC and adaptor | | Erratic movement / missed steps | Interference or wrong pulse timing in driver settings | Reduce kernel speed in Weihong software (try 100KHz instead of 250KHz) | | Adaptor LEDs off | No external power supply | Most adaptors need separate 24V (check jumper settings) |
