I chopped up my IKEA Dioder controller PCB so i could control my IKEA DIoder ledstrips with the Velleman K8400 Vertex 3d printer. There are some testpads on the PCB so its very easy to solder on some wires . I reused the connectors(one 5 pin and one 4 pin) from the IKEA pcb. Now i can control colors/on/off from the LCD menu and from gcode which is really nice. Now i have different colors on outer and inner periemter, finished and heating extruders. I shortened the wires from the ledstrips, made a cable from the 5pin IKEA connector to the 12pin on the Velleman board. Only one thing to look out for is the color coding on the 5pin cable. BLUE wire is signal RED, GREEN is BLUE and RED is GREEN .
If anyone wants to i can scetch up a quick schematic for the wiring if the last picture is not clear enough.
