This article shows how to replace the Controller board for an Emblaser Pro.
IMPORTANT: We classify this process and Medium to Advanced. There are delicate components and connectors on the controller board that need to be handled very carefully.
IMPORTANT: The electronics on the controller board are sensitive to static damage. When performing this process, set up in an area where you can sit comfortably and place parts within hands reach. Do not pick up electronics and walk around with them or pass them from person to person.
IMPORTANT: Be very careful with all connectors, especially the FFC clips. They are very delicate.
Safety
Before opening any panels or performing any work on your Emblaser Pro, ensure it is unplugged from the mains power.

Installing the new Controller board
Step 8: IMPORTANT MODIFICATION
If you machine has a serial number earlier than EPRO-15156 you will need to perform this simple modification to allow your new controller board to be seated easily.
