So, compared to Jordan's test pics, I'm getting the output that he got with only 1A.
I have checked the 'sister' module to this one and the 445 on that is now running at 2W, so no issues with that one.
Planters, if the waveplate is incorrectly aligned, will i see a lot of spill in the cube? Would I be right in thinking I'll be getting the rest spill out the other side, which should be measurable?
P.S. I did also confirm that the current was actually going up at the point I started to see the power going down again. At 2.3A I was down to 1.2W
