Once you have the jk 721 cutting plotter driver working, keep it stable:

  1. Disable Windows automatic driver updates. Windows Update will sometimes replace the CH340 driver with a generic Microsoft driver that fails. Use wushowhide.diagcab to hide CH340 updates.
  2. Use the same USB port every time. Windows assigns a new COM number per USB port. If you switch ports, COM3 becomes COM7, and your software loses connection.
  3. Ground your plotter. Static electricity from vinyl cutting can reset the USB chip. Connect a grounding wire from the plotter’s chassis to earth ground.
  4. Regular firmware reset: Turn off the plotter, unplug USB, wait 30 seconds, reconnect. This resets the driver buffer on the mainboard.
