Windows PC can't connect to Creality 3D printer over USB


Trying to connect a Windows PC to a Creality 3D printer over USB, but unable to do so. 

Using a program like XLoader to connect to the printer, it shows "Can't open port" even with a port selected. With Cura, it says there is no printer connected. 


The Creality drivers are not properly installed, so Windows does not know how to connect to the 3D printer. 



To install the drivers:

  1. Download the Creality printer drivers provided by TH3D, found here.
  2. Launch Device Manager
  3. Expand Ports (COM & LPT), then right-click on the USB port
  4. Select Update Driver
  5. Click Browse my computer for drivers
  6. Navigate to the file location of the file. In my case, on a Windows 10 64-bit machine, the file location was C:\Users\SuperheroDIY\Downloads\CDM v2.12.28 WHQL Certified
  7. Click Next


Your drivers should now be updated. If you close and re-launch Cura, your printer should now be connected.  A program such as Pronterface or XLoader should now show the printer connected to the appropriate port.
