Thank you again everyone for all the help getting the laser module up and running. Guffy that tip to use the fan pin with Mosfet to ground and a different pin for the +5 source was genius.
I used the laser to cut this 30 mm Kaizen foam. I focused the laser to be focused at 15 mm up from the spoil board. So it would have the same cutting power for both halves of this material. I did not use any air assist. These were cut at 30 mm/s at 78% power on a 15 w laser. It took 13 passes to cut all the way through but I could have stopped it at 11 passes. I just wanted guaranteed clean cuts all the way through. The head lowered .1 mm per pass. I did learn that this worked great to cut anything inside the foam but the outer edges cooled off too quickly in my cold garage. So around the edge if I was trying to trim off 1 mm it couldn’t cut all the way through the foam. It needed at least 3-4 mm of insulation around the edge before it could cut all the way through.
These are order takers for our sales reps to use at conventions. The clipboard will be used to take the order and hold everything they could need.
Next I will be cutting 62 mm tick kaizen foam for use in some tool boxes that will be shipped with the booths to the same sales conventions. I am not sure yet if the laser can cut through that. If not I have a new foam cutter pen that works like a long soldering iron. That should work if I make a tool mount for it.
Big thanks to Ryan for designing an amazing versatile CNC machine that can be scaled up accommodate large material like this. I need to rebuild my MPCNC to handle material stock up to 4 ft long so I can cut an entire sheet of foam all at once.
