I've tried upgrading the firmware on the Etherdream 2 DAC but the issue remains.
I will explain exactly what I'm doing in Maxwell to re-create the problem...
1) Open Maxwell app
2) Load a preset file and select a preset
3) Click the Power button
4) Click ON/OFF in the DAC selection section with settings showing:
* DAC TYPE: EtherDream
* DAC INDEX: 0
* DAC PPS: 20000
Expected result: laser should output as per preview window
Actual result: Laser seems to output something for a split second then stops
I suspect that the Etherdream driver DLL included with Maxwell is incompatible with the Etherdream 2 DAC because I had similar issues with LSX until I upgraded to the latest version which included a newer Etherdream driver DLL.
