First "Tutorial" is Ready (Poster)


a few days ago I had the idea to publish the tutorial as a poster, with all the circuits on it. This was the fastest and easiest I could do. So here it is.

It's not really a tutorial. Because for a tutorial you need much more time for writing the instructions. It's a poster. I have attached two pdf- files with the poster so you can print it in a4 or a3, furthermore I also have this picture in very high resolution attached, so you can view and print it in any size you want.

Circuits of a laser cutting and engraving machine, based on the Thunderlaser DF212 or DF211 controller. Designed for the chinese K40 series (40W).

I hope this is enough. You can see how the parts are connected. I have a short description in the top-left corner. But I think this should be absolutely enough for people who have no plan how to connect the parts :)

In the following picture you can see the interior of my machine. I'll tidy it up and make it look better ASAP.

The laser power supply is not inside the case yet. I have glued heatsinks to the drivers. They become really warm during long jobs. More pictures will come soon. A video of my machine in in action will come maybe this weekend or next week (because I need to make a seperate Youtube account).

Download the zip archive with the poster as pdf, jpg and png. The zip archive and all files should be virus free.

Have a nice Easter weekend!


  1. Hi, why is one stepper driver set to 1.1A and the other one to 0.9A? Thanks :)

    1. Hi Tobias, it's because the y-axis is much heavier. Therefore it has slightly bigger motors which need a higher current.

  2. Excellent and helpful post… I am so glad to left comment on this. This has been a so interesting read, would love to read more here…. laser cutting machine
