Can someone with a 40w Chinese laser take a picture of the connections or draw a picture of the wires that are on the larger connector with the proper wire colors? This is a 'stab in the dark' trying to get my machine running.

There are dozens types of 40W laser machines.
You better try to resolve system.
Make a photo of this "larger connector"

It is the connector that has the following connections:


TH TL WP G IN 5V

The other connector is for the mains supply of 110v. That one is not a problem. This is the power supply that is with all of the EBAY 40watt lasers that sell for about $750.00.

5V is 5V output
If you use potentimeter to set laser power just use it with
IN and G (Ground)
WP is water protect.
If you dont use water protect just connect to G (ground).
TH is High Signal 5V starts lasing 0V stops lasing
TL is Low Signal 0V starts lasing 5V stops lasing

What you use TH or TL depends on your mainboard.
