K40 Chinese laser conversion to Arduino
I also would like to put this in the form of a nice Instructable so others can upgrade their machines as well.
But during my research I noticed that several different versions of the controller, laser power supply and control panel exist.
If you are interested in upgrading your machine so you can use Inkscape directly and no longer need a dongle and crappy software:
Post a pic of your laser power supply (including a clear pic of the connection terminals),
a pic of your control panel (both from the outside and the bottom),
let me know if you already have safety switches for the lid and water flow.
Everything posted here in time will be included in the Instructable if it is different from my machine.
Once the Ible is finnished you will get detailed instructions on what you need, how to program the Arduino, get the plugins working in Inkscape and how to do your first real engravings and cuttings on the new setup after calibrating everything.
Here is a video showing raster and vector engraving followed by cutting the piece out - what more can I ask for if only spare parts are used? ;)
