Caution: Counterfeit cards from AliExpress often lack the proper opto-isolation. They may work for a month then fry your motherboard’s PCI slot. Always buy from an authorized Weihong distributor (e.g., Weihong direct, CNC-Plus, or Bijia Electronics).
6. Recommended Workflow for 3D
Issue A: “Stuttering” on smooth 3D curves
The PCIMC-3D adapter is typically installed into a computer's PCI expansion slot. It translates G-code instructions from the software into pulse signals that drive the stepper or servo motors for the X, Y, and Z axes.
