QR Scanner

INFORMATION: This function is only available for MASSO G3 and MASSO Touch in version 5.0 or higher.

INFORMATION: This feature requires the use of MASSO Link version 2.1 or higher

What it Does

The MASSO QR Scanner feature allows the user to scan a QR code which will then automatically load the file into memory ready for the user to run the program.

This feature requires the use of MASSO Link version 2.1.02 or higher which is used to create the QR code.

The user can also create their own QR codes using the MASSO protocol.

Scanner Requirements

  • The scanner must be a USB scanner.
  • The scanner must be capable of scanning QR codes
  • The scanner must be set up to simulate a USB HID-KBW. In this mode the the reading module in the scanner will become a virtual keyboard to output data to the host.
  • The scanner needs to be set to send a CR (carriage return) at the end of the scanned code.

Many barcode scanners come with a user manual that include a set of series of barcodes that can be used to program the barcode scanner itself.

Not all barcode scanners are designed to read QR codes and will read 1D codes only. These are the single line codes found on product packaging and will not work with the MASSO QR codes.

Wireless Barcode scanners with a USB receiver can be used with MASSO as long as they comply with the above requirements.

Bluetooth scanners will not work with MASSO so if purchasing a wireless scanner ensure that it is not Bluetooth as they can look similar.

Setting up your scanner

Installing your QR Scanner

Step 1 - Do not plug your QR Scanner into MASSO yet. If you have already plugged it in unplug it before you start.

Step 2 - In the F1 Screen select QR Scanner and the following screen will be displayed.

Step 3 - Plug in your QR Scanner. You will see the Vendor ID and Product ID displayed.

This indicates the scanner has been detected and identified.

Step 4 Press Save and the QR Scanner install is complete.


If the QR scanner does not work as expected

  • Put a Gcode file onto your flash drive and name it project.nc
  • Go to the F2 page on MASSO and Scan the QR code below. The file should load into MASSO ready to run as shown.


  • If you see the following message it means that the file is not present on the Flash drive or you have it in the wrong folder on the Flash Drive. For this test the file needs to be in the root directory.

  • If you do not see either of these messages when you scan the QR code please confirm that the scanner is set up as a USB HID-KBW virtual keyboard and is set to output a carriage return at the end of the scan.

  • You can test your QR scanner on a PC. Plug the scanner into a USB port on your computer and open your text editor of choice. Notepad works well in Windows. Scan the QR code 3 times and you will should see the following on your screen.

This indicates the scanner is reading the code and has carriage return turned on.

If you see the following then carriage return is not turned on and the scanner is not set up properly.
