This isn't so much of a step, but a story. This shows me discovering the stepping, the power of the laser and the first time I cut anything out. If you want a better view of how this actually works, or for more a different perspective on some difficult parts this might be a good place to get it:
Here we start with an overview of my lab, and also all the parts, a basic diagram of how things are set up. A close up view of the "print head" is here if you're curious:
I also get the stepper motors going here!
This is part two where I find out what it means that I have two stepping scanners connected:
This is the part where I take you to show you the power of the laser. You can see the beam outside, and also you can watch as I hold it to burn paper by hand:
Now you can watch as the entire setup is connected and hooked up. Hear my surprise when I actually get it to cut a diagonal line:
lastly hear me as i try out postscript sending for the first time, watch the scanner as it cuts, you get a nice close of up how it's all hooked up.
And that's it, I hope this extra story line helps. This is a fun project, and if anyone wants to improve it I'm sure it can be done. Show me your best!
All the best.
