I too had misunderstood. When I selected configure plugin, I saw the Darwin plugin rev as 1.160 so thought I was okay. The two numbers in the waterfall screen were 1.11 and 1.08. So I just removed the driver using the settings and then reinstalled. Now the waterfall shows 1.11 and 1.16.
Unfortunately, the port 2 inputs still work the same.
At least now I know why I can't get M4 to control my second spindle (K2). The diagnostic light comes on but there is no indication in the history that Darwin was commanded.
Sage,
The next time you load an updated version of M4, I think your default configuration will be reset. I suggest you open with static GUI and create a new profile by using copy profile and naming the new profile. Right now I'm using Art's suggestion and calling it Darwin setup.
