Can't get my K40 to work on Lightburn

Hi Bernd, Firstly have I got your name right? I had a brother Bernard and I feel like I’m missing a few letters when I write Bernd.
I’m up for the challenge and have had a lot of them with my 3D printer, so I know what I’m in for. And I’m looking forward to what lies ahead in regard to what I can do with this machine. I am retired now and have been for ten years. My trade is a letterpress/offset printer which has helped me with a number of things related to layout, fonts and machines.
Thank you again for your advise I will change the controller and fire up LightBurn as in particular I like the fact it’s one programme for both artwork and the laser controls. I hooked my old Elksmaker and it works with LightBurn so it makes sense for me to have both machines working on the same programme.
I am looking into printing my own nozzle on the 3D machine and checking out the small compresses today. All the best for now.
