If you want to upgrade the EZCAD3 software to a new version, here are the steps:
- Download the new version of EZCAD3 software first, and save it to your computer.
- Find the folder of the older version software, copy all “MarkCfg*” files in “PARAM”, and paste them to new version software’s “PARAM” folder.

Generally, you can begin to use the new version of EZCAD3 software.
For safety, you can also check if the setting parameters in the new version software are all the same as the parameters in elder version.
Click “Para[F3]”, and check the parameters in these items which are marked by a red frame in the following picture.

As we can’t open two software at the same time in one computer, you can open and take some pictures for these setting parameters in elder version first, then close it and open the new EZCAD3 and compare the setting parameters are the same.
Notice:
There are some new settings in the new version of EZCAD3 software that elder one doesn’t have, just keep these new settings as default, no need to set them.
