I recently made a Swappable hot end on which this laser engraver can be placed. I intentionally placed the female version of the d sub connector at the tool side because the mixed male version fits a regular female one and not vice versa.
A major advantage I have encountered is that you don’t have to connect the laser directly to the control board, or worse, with a switch. You can just use the schematics as shown in the swappable hot end and connect the laser to the part fan and the fan of the laser to the hot end fan. In this way the fan is constantly spinning which keeps the engraver colder.
I have made a video about this upgrade and it shows how I managed to laser engrave a 3D printed part. I have added the cross to the files which I have used in the video to determine the tool center point of the engraver relative to the 3D printer nozzle.
