From this laser power supply strip, only the IN connection is modified the rest just stays as is in the K40.
Install the push buttons for pause/resume and reset and plug in the wire connectors into the controller.
The flat ribbon cable (which contains the ‘X,Y end stops’ and ‘X axis motor’ connections) goes into the ribbon female connector only in one way. Plugs: Unplug the existing controller plugs one by one and plug them over into the new controller as depicted in the diagram above (the ‘ Y axis motor’ connector and ‘ power connector’ labeled ‘24V/Gnd/5V/Lo’ on the K40 shield which is a 4 wire connector).The diagram below depicts the set up of the connections: The connectors go straight into the board and uses a lock mechanism to keep the connection steady. The hardware conversion consists of 4 easy steps designed for easy installation and for non-tech savvy people. The K40 Shield is powering the AVR board below it. It’s for those who want to use the AVR as an Arduino standalone and program it. Note: The barrel jack op the AVR board is not being used. Tips: Take photo’s of the existing NanoM2 board/endstop so you know what and how it was connected.
Tools: All you need is a pair of pliers to cut one wire (optional), a screw driver to connect one wire.
