I was talking with @raykholo about the design of the daughter board connector that takes the main PSU power feed on the C3D boards. Specifically around the plug used by the various power supplies.
It appears that mine is somewhat backwards from his but I’m wondering if there are even more options out there. Attached is a picture of mine which as you can see doesn’t fit the board connector properly, but does work while his fits properly and appears to be reversed from mine.
OK, so we’ve managed to match how I’m guessing all the M2NANO boards are made but there is variation in whichever cable the assembling technician seems to grab, probably from a highly cross contaminated pile. +Peter van der Walt this sound like fun to you?
