Creality FTDI F232R USB to Serial Adapter Chip Drivers

Some users may have issues connecting their Creality printer (all models) to their computer via USB. If you are seeing an error message of "System.IO.IOException", this is likely a driver communication issue. Since Creality does not use the same Serial to USB chip as most printers, you will need to install a new driver.

For most Creality printers, you will need the FTDI Driver for this install process. If your Creality printer has a V1.1.4 board, you will want to use the CH340 Driver instead.

Step 1:

Connect your Creality printer to your computer via USB cable and navigate to your Device Manager. For Mac OS users, the equivalent to this is the System Report, accessed from Menu > About this Mac > System Report.

Step 2:

Locate the COM port (ex. COM3, COM5, COM7, etc.) that the Creality printer is communicating through, and uninstall its driver. You may uninstall this by right-clicking the COM port and selecting Uninstall Driver.

Step 3:

Once you have downloaded the appropriate driver, you will now need to install this by following this guide.
