Troubleshooting - US Cutter MH-721 Manual

Troubleshooting

Problem
The cutter is unresponsive to
communications from the
computer and software.
The cutter performs erratically
during cuts, stops cutting
before the cut is finished, or
cuts lines that do not appear in
the design.
When starting the SignBlazer
Software it fails to find
updates.
Communication issues can arise if the cutter was powered on while
the software is trying to send data to the cutter. Exiting the cutter
screen of SignBlazer and returning to the main SignBlazer screen
may resolve this issue. If not, save all work and try exiting
SignBlazer and restarting with the cutter powered on. It is good
practice to start SignBlazer with the cutter powered on to avoid
communication problems.
Make sure that your output device in SignBlazer is set to the
correct COM port (Found by selecting File>Cutter from the menu on the
main SignBlazer screen, and then selecting Setup from the top menu
buttons). Your COM port can be found by following the instructions in the
"Finding Your COM Port" section of this manual on page 14. You can
change your COM Port by right-clicking on the COM Port in the
device manager and going to the advanced section of the Port
Settings tab.
Adjust your Flow Control settings to Hardware by first locating
your COM Port in the device manager (By following the instructions
on page 14), then right-click the COM Port and select Properties.
On the Port Settings tab, change to Flow Control option to
Hardware.
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 connecter or a
PCI card serial adapter for your computer.
This is a regular occurrence of the SignBlazer software and should
not be considered a problem. All features of the software will
continue to work in trial mode without updates.
To deactivate the update process, redirect the SignBlazer shortcut
(of either the desktop icon or start menu selection that you use to open the
SignBlazer software). Right-click it and select Properties. From the
Properties menu, change last section of the Target option from
"sb.exe" to "sbnt.exe". Press the Apply button, then the OK
button. This will bypass the update process.
