Titan Plotter - blade performing erratically

See expert from the Titan Plotter user manual regarding cutter performing erratically during cuts

PROBLEM
The cutter performs erratically during cuts, stops cutting before the cut is finished, or cuts lines that do not appear in the design.

SOLUTION
Some computers do not work well when connected via the USB port of the cutters. If you are having problems while cutting and are using the USB cable to connect from your cutter to computer, you may wish to try the serial cable connection to avoid further problems. If a serial cable connection is not available on your computer, you can try a third party USB to serial connector or a PCI card serial adapter for your computer.
