Checking the buffer output

I thought that I should check the buffer output before I fixed up I_PWM2.

The output was terrible. I found 2 problems

1. The ground of the buffer was connected to a part of the ground plane that was "dead copper" - FIXED

2. I had the inputs and outputs for I_PWM1 and 2 around the wrong way - FIXED

now the inputs to the opto couples are fine.
