Easel will work with the E3/E4. However, if not you can try to configure it. Easel writes different values to the EEPROM. These will have to be changed back to default values out outside of Easel. I have not found a way to change it with Easel. Easel does not have an E3/E4 configuration.
• Install and load UGS Platform version – Please see our quick start guide
• Connect the E3 to UGS thru the USB connection
• Click on the menu Machine>>Firmware settings
• When the dialog box opens, go thru each $ value and change the numbers back to the default E3/E4 setting. These settings can be found in the assembly manual.
