@donkjr May it help with high resolution pics of it? I´m in Sweden but i can send you mine if it helps better.
@HP_Persson Sure lets try the pictures, I have done that before.
I am sure you know this but if you can take them from above as parallel to the board as possible that is the best.
Take one of the top and one of the bottom from the same distance but including the entire board.
I take the pictures, print them out and then glue them to either side of a substrate so it is close to feeling like a real board 
Take any other pictures that you think will help especially where traces disappear or the chip numbers are hard to read in the larger picture.
Thanks in advance!
@donkjr Sure, i have a overhead camera rig for my DSLR so no problems with pics. I´ll email you a zip-file later when done!
Another question I have is about the PWM cable that comes with the cohesion 3d mini. It seems that it is meant to take the place of the pot control. I thought I heard that some people are using the cable and the pot together to act as a cut off and limit the power. Just asking because with out the PWM cable I wonder if the laser power would not change by itself and would only be manually controlled by the pot.
If this is the case I how would you wire the pot and PWM cable to work together?
@HP_Persson again you ROCK!
@ALFAHOBBIES I will let Ray tell you the latest on wiring.
Just did a lot of reading on the cohesion group and it seems I don’t need the PWM cable. Seems the cable can be used to bypass the pot. But it is recommended to stay with the pot or the digital board depending on what you have or like better. PWM is controlled by gcode and the smoothie.
@ALFAHOBBIES you always need a PWM connection to the controller and I think the latest recommendation from RAY is the L connection on the LPS. You can elect to use or not use the POT but I think Ray recommends leaving it in.
My recommendation is both PWM on L and pot installed.
You don’t wire the “pwm cable” that comes with the Cohesion3D kit. You keep the digital panel or pot connected. That sets the ceiling for your power level, then software controls the power within that range.
Ray, thanks. You say in the install instructions to put the SD card in the slot. It has software for the board. Does it run that software right off the SD card? So I just leave the SD card in all the time so it can run from it?
Put card in, leave card in.
I only ask because I’m used to 3d printers that have memory on them and do not need an SD card to hold setting data.
@donkjr , emailed you a couple of days ago, check spam-folder. May ended up there 
@HP_Persson can’t find any mail?? Try again or over to hangouts?
@donkjr I sent from my gmail instead now, maybe works better
@HP_Persson and I shared pictures and concluded that creating a schematic is not a useful exercise since some parts at blanked out and it is likely its a microprocessor anyway. This will not stop us from creating a “How To” guide.
@HP_Persson here is what I took from our conversation and added the wire colors from @ALFAHOBBIES pictures above. Can you verify.
Gnd orange
In yellow
5V white
P+ n/c (sometimes actually wired to K+ but open in the wiring)
P- Red (actually wired to K-)
BTW does this digital panel fit into the standard K40 cutout in the right cover? If so it would be nice to have a cut outline for a new panel to go with this guide that allows the panel to stay in place with the pot and its digital voltmeter added. Don’t know if there is room?
Seems like it´s routed different on the two types of PSU´s existing.
I made this graphic a couple of days ago, and it seems like this is how they use it.
Only thing that seems to differ is one less GND on the lower one, and P+/GND is swapped around.
PSU with small white connectors.
From 5V on PSU to 5V on panel
From IN on PSU to IN on panel
From GND on PSU to G on panel
From K+ on PSU to P- on panel
From K- on PSU to – not connected.
PSU with all green connectors
From 5V on PSU to 5V on panel
From IN on PSU to IN on panel
From GND on PSU to G on panel
From L on PSU to P- on panel
@HP_Persson You did the heavy lifting I will blog post this in aggregate soon :).
