Once the driver is installed, your JK Series will appear as a (e.g., COM3).
Goldcut JK series cutters (such as the JK721, JK871, and JK1351) do not have a native USB controller. Instead, they use an internal USB-to-Serial conversion chip. When you plug the USB cable into your Windows 10 PC, the computer relies on a driver to translate that USB connection into a Virtual COM Port. Most Goldcut JK machines utilize one of two chips:
GoldCut's older drivers often don't have a valid digital signature, and Windows 10 (especially 64-bit versions) blocks these for security reasons. To temporarily bypass this:
: This is often caused by using a low-quality USB cable. Experts recommend using a USB to RS232 Serial Adapter with an FTDI Chipset for the most stable Windows 10 connection. goldcut jk series windows 10 driver work
You may not need to install a specific cutter driver at all. When you plug in the cutter, Windows 10 will attempt to install a driver automatically. Check in under Ports (COM & LPT) ; your cutter should now appear as a USB-SERIAL CH340 (COM#) device, like COM5 in the example below. This shows the driver has installed correctly. You can then send cut files directly from Inkscape.
: If the standard installer fails, right-click the unknown device in Device Manager, select "Update Driver Software," and manually browse to the folder containing the extracted setup files (e.g., GOLDCUT JK Series.inf Disable Driver Signature Enforcement
The Goldcut JK Series is known to work with several major design and cutting programs: Once the driver is installed, your JK Series
Look for "USB-Serial" or an "Unknown Device" under or Other devices .
If your computer does not recognize your cutter, or if your cutting software freezes when sending a job, the issue is almost always a driver mismatch. This comprehensive guide will walk you through the exact steps required to make your Goldcut JK series plotter work flawlessly on Windows 10. Understanding the Core Issue: The USB-to-Serial Chip
If the standard installation fails, try these more advanced techniques. When you plug the USB cable into your
If the automatic installation fails, you can force Windows 10 to accept the unsigned driver through a manual process.
This often points to a software configuration issue. Ensure your cutting software (like Inkscape, SignCut, or Sure Cuts A Lot) is configured to use the correct that your plotter is connected to.
