Complete Guide: Cutting Plotter KI720 Driver Download & Installation
If you’ve recently acquired a KI720 vinyl cutting plotter or have updated your computer system, finding the right driver is the most critical step to getting your machine running. Without the correct communication bridge between your PC and the hardware, you’ll likely face "Device Not Found" errors or erratic cutting behavior.
This guide provides everything you need to find, download, and install the KI720 driver for free, ensuring a smooth workflow for your signage and crafting projects. Why Do You Need a Dedicated Driver for the KI720?
The KI720 is a popular entry-level professional plotter known for its 720mm (approx. 28-inch) cutting width. Most modern versions of this machine use a USB-to-Serial interface.
The driver acts as a translator, allowing design software like SignMaster, FlexiStarter, or Artcut to send vector paths to the plotter's motherboard. Using the wrong driver can result in "garbled" cuts or the machine failing to respond entirely. Where to Download the KI720 Driver for Free
To ensure your computer recognizes the plotter via USB, you typically need the CH341 or FTDI chipset driver, depending on your specific model’s internal board.
The Manufacturer’s CD: If you still have the disc that came with the machine, look for a folder labeled "Driver" or "USB Driver."
Official Support Portals: Check the website of the distributor where you purchased the machine (e.g., Vevor, USCutter, or similar brands that rebadge the KI series).
Standard USB-Serial Drivers: Most KI720 plotters utilize the CH341SER driver. This is a universal driver used by many Chinese-manufactured plotters and is available for free on various driver repository sites. How to Install the KI720 Driver (Step-by-Step) Step 1: Preparation
Do not plug the USB cable into your computer yet. It is often better to install the software first to avoid Windows assigning a generic (and often non-functional) driver to the device. Step 2: Running the Installer
Download the CH341SER.EXE (or the driver specific to your KI720). Right-click the file and select "Run as Administrator."
Click the "Install" button. A message should appear saying "Driver install success!" Step 3: Connection & Verification Plug the USB cable into the plotter and your PC. Turn the plotter on.
Right-click on "This PC" or "My Computer" and select Manage > Device Manager. Expand the Ports (COM & LPT) section.
You should see "USB-SERIAL CH340 (COMX)" (where X is a number like COM3 or COM4). Note this number. Configuring Your Cutting Software
Once the driver is installed, you must tell your software where to find the plotter:
Software Port Settings: Open your cutting software (e.g., SignMaster).
Device Setup: Select "KI-720" or "Generic HPGL" as the model. cutting plotter ki720 driver download free
Output Port: Choose the COM Port number you noted in the Device Manager.
Baud Rate: Most KI720 models communicate best at 9600 or 38400. Troubleshooting Common Issues
Driver Signature Error: If you are on Windows 10 or 11, you may need to temporarily disable "Driver Signature Enforcement" to install older plotter drivers.
Machine Not Moving: Ensure the plotter is in "Online" mode. If the screen says "Offline," it will not accept commands from the PC.
Static Electricity: Use a grounded outlet. Static buildup in the vinyl can sometimes interfere with the USB connection, causing the driver to "drop out."
The KI720 cutting plotter is a workhorse for any small shop, but it’s only as good as its connection. By downloading the correct USB-to-Serial driver and matching the COM port in your software settings, you’ll be ready to cut vinyl in minutes.
To set up your KI-720 cutting plotter, you typically need two types of software: a communication driver (to bridge the USB/Serial connection) and cutting software (to send design data to the machine). 1. Communication Driver (Essential Connection)
Most modern KI-720 models (often associated with brands like VEVOR) use a USB-to-Serial emulation. To get your computer to recognize the plotter, you need one of the following:
FTDI USB Driver: This is the most common driver for value cutters. You can often find this directly via the FTDI Chip website if the provided disc is missing.
STM Virtual COM Port Driver: Some users report success using this driver for USB emulation on KI-720 models.
Manufacturer Support: Official manuals for the VEVOR KI-720 suggest using the drivers provided on the included USB utility disk or CD. 2. Cutting Software Drivers

In the world of signage, garment decoration, and small-scale manufacturing, the cutting plotter is an unsung hero. Among the many models that have graced workbenches over the last two decades, the KI-720—often a rebranded version of generic Chinese or early GCC (Graphic Cutting Center) designs—holds a particular place. It is a classic "workhorse" machine: affordable, robust, and capable. However, for the modern user facing a new computer or a fresh operating system install, a single, frustrating problem emerges: the quest to download the cutting plotter KI-720 driver for free.
This seemingly simple task is a modern parable about planned obsolescence, the fragility of digital infrastructure, and the resilience of the maker community.
