Appendix B Troubleshooting

Communication Issues

There is no “USB-Serial” COM Port connection available in the list of available COM ports.

 Unplug the KNK from your computer. In MTC, go to Help>Advanced>Download and Install FTDI
D2XX Drivers. Once the drivers have installed, reboot your computer. When your computer has
finished restarting, reconnect the KNK to your computer. You should get a pop-up that will finish the
installation.

 If this fails, again unplug the KNK from your computer. Download and install the driver for the KNK
Maxx/Groove-e from here:
http://knkusa.com/resources/

 Once you have downloaded and installed the driver, reboot your computer. When your computer
has finished restarting, reconnect the KNK to your computer. You should get a pop-up that will finish
the installation. If you continue to have trouble, contact your KNK dealer or KNKUSA.

When I tried to cut, I got an error message that said: “Overlapped I/O Operation is in Progress”
 Verify the correct listing is selected in the Serial Port menu.

 Verify that the USB cable is securely plugged into your KNK and into the computer.

When I tried to cut, nothing happened, no error messages either.
 Make sure your cutter is online.

 Check the baud rate on the machine to make sure it matches what is selected in the window.

 The Latency Timer needs to be changed on the Com Port assignment. To do this, watch the video
called “Communication Fix” at this link: http://www.iloveknk.com/FreeVideos/Support/

I’ve reinstalled the driver and change the Latency Timer, but my computer keeps losing the connection to the
KNK.
 You may need to change the power settings for the USB ports. To do this, go to Windows Control
Panel>System and Security>Power Options. Click on Change Plan Settings and then Change
Advanced Power Settings. In the Advance Power Settings window, click on the + next to USB
Settings. Make sure the USB Selective suspend setting is Disabled.

 If the KNK still becomes disconnected, make sure you are using the latest plugin. These are available at
http://knkusa.com/resources/

 Try applying Flatten Paths before sending to the cut window. Select your shapes, click on the wrench
icon at the bottom of the screen, and select Flatten Paths from the pop up menu.
