|This is the scanner I'm going to use as the base.|
|A stepper motor from an old printer.|
|A metal rail & old printhead.|
I was thinking about the possibilities how to create the XY-controlled CNC from these parts, and came up with three sketches.
I admit, I'm very bad at drawing, but anyway, I decided to share these sketches with you.
|First idea of the CNC, a very shitty one. The laser points up.|
The surface to be engraved would be held upside down over the CNC byt something, and the beam is pointed upwards from the scanner. Well, you can imagine how this would make the whole set-up and engraving process a pain in the ass. Especially with heavier items.
Next idea, already a bit better one:
|2nd sketch of the CNC.|
Now the scanner is held upside down, and the engraved surface is lying beneath it. The rail is sticking a bit out from the side (it's wider than the scanner). The laser points down. The problem with this one is that it limits the engravable things a bit. It would be hard to put bigger items under it, like a guitar, a synth, or things like that.
With the third idea I think I nailed it.
|Third and probably the final sketch of the CNC.|
Now you can put whatever items under it. The metal rod & pulley system is held high by a big piece of something. I just wonder how the scanner motor & tray will pull it off with all that weight. Obviously I'll need to make it as light & balanced as possible. Or then I need something to hold the rail from the other end...
I have no idea yet how I will do all of that. These are just the first ideas I came up with.
