Hello all.
As I am making a few of these now fully boxed up with panels, I thought I would post a quick thread showing you how to assemble the CMM2 board into the case with the panels, WITHOUT losing your marbles, as it can be a bit fiddly.
STEP 1: Gather together the CMM2 board, the case, the panels, the spacers and the securing screws. Place the half of the case with the PCB standoff's on a flat and LEVEL surface.
This is important, as a level surface will help prevent the spacers from sliding off the PCB standoff's moulded in the case half.
STEP 2: Place the four 5mm spacers as shown here.
You don't need to glue the spacers down, or even stick them down, just place them as shown, and then DON'T bump the case!
STEP 3: Fit the front and rear panels to the CMM2 board, then pick up the board using both hands VIA THE PANELS. IE: Don't try to pick up the board, as the panels will immediately fall off.
Provided you use a SLIGHT side-to-side force to hold the panels against the edge of the CMM2 board, everything will stay put while you lift it and lower it into place in the case.
STEP 4: GENTLY lift the board up off the table, and lower it down into the case. You must be precise, and you must also be gentle as you line up the front and rear panels in the slots in the case, but it is very easy to do, once you have done a couple of them. The key is to be SLOW and precise, and DON'T try to rush it or force it, or you will bump the case, and you WILL dislodge the spacers.
This image shows the complete panels and CMM2 board assembly lowered into the case, but not yet screwed down.
STEP 5: Visually check that the spacers are still where they should be, and if not(they will move very easily), then use a fine screwdriver to GENTLY coax the spacers back to where they should be.
STEP 7: Now fit the screws and tighten. You DON'T need much force, so don't overdo it, or you will just strip the plastic standoffs then they are useless.
Hopefully that will help people save sanity while assembling cases.
