Problems communicating between plotter and computer USB Connection

Have you installed the drivers for your USB communication? They are provided by your dealer or the manufacturer of your plotter. Many import plotters use an FTDI USB/Serial converter internally so you need to install the FTDI drivers for your computer to see the plotter. Please follow this link for the correct drivers. http://www.ftdichip.com/Drivers/VCP.htm

Please note many MAC users have a tough time getting communication with some import plotters. Generally this is a firmware or driver issue but we recommend bypassing the internal USB/Converter card if possible and using a Keyspan Adapter. Remember all adapters are not created equally and some third party adapters will not work to run a plotter. This is also a better form of communication on PC's.

Once you have installed the drivers open SIgnCut click the cutter buttonn then check the output device. Generally in windows your correct port will be com 3 or 4 and it might be labeled serial com port, you can confirm this in device manager. On a Mac you will be looking for a port dev/cu... but not bluetooth. Select the correct port, leave your baud rate at the default (must match the setting on the plotter) and then close that dialog.

Load your plotter and make sure it is set online then try test cutting the SIgnCut logo by clicking the scissors icon and choosing cut out.
