Hi, I just bought my first fiber laser today, a ComMarker B4 30w fiber laser. I plan to make an enclosure for it using 2-3mm thick aluminium sheets screwed into a extruded aluminium frame. I intend to have three of the four sides open upwards and out of the way somehow. Unfortunately the laser does not come with a interlock socket on the back so I have to wire it up myself.

The manufacturers dont mind you popping off the side panels at all and even have it listed as a solution in there troubleshoot guide. I was offered to have the interlock added if I paid them $100 more or i could just wire it in myself. I heard it is one of the 15 pin cables that need to be modified from the sales rep.

I plan to instal a ribbon extension cable while taping up the exposed metal parts of the plug with kapton tape to avoid short circuits. Unfortunately I dont know which wires i need to attach to or reroute. In the manual it shows a picture of a FBLI-B-LV4A control board but it might have been changed since the manual was made.

I plan to add a key to stop it running without it and a pressure switch to cut the laser when the enclosure door is open. Any information on how I should wire it in would be much appreciated.
