For the majority of customers, the screw holes line up and the new board is a drop in replacement. Unplug the wires going to the stock circuit board, remove the white panel. Removing the nuts was enough to free the panel. Here there are 3 nuts, 2 on the bottom and 1 on the left side. Loosen up the screws/ nuts holding the white panel in place. I call this the “No Ribbon and White JST Connector Power Supply” Variant:

Take a good picture of your stock electronics in case you need to backtrack later. We will do our best to address the different ways and if something seems different in your machine than what you see here, please ask! There are multiple ways these come wired. Shown are some possible configurations of the K40. Caution: It may or may not apply depending on the parts you intend to buy and the model of K40 you are running.Congratulations on your purchase of a Cohesion3D LaserBoard! When you decide what parts you want I(we) can help you create a wiring diagram so that you get the correct parts and wire them correctly.Īttached is a diagram for a similar supply conversion I helped someone else with. the “L” signal from the stock controller to the proper signal on the new LPS. the new LPS into the chassis cable harness connected to the old LPS insuring that the coolant, laser switch and fire are all reconnected properly. the new 24V and 5V supplies to the stock controller card and insure the controller ground is tied to the the LPS ground the new LPS AC input and safety ground are wired correctly. I did however help someone else and I believe the new LPS handled the 5V ok.

I do not know how safe it is to run the 5v from your new supply to the stock controller as I do not know the capacity of the new supplies 5V nor the load of the stock controller. You can run 2 external supplies: 24V in addition to your new LPS.
