my diy cnc machine

Like every self respecting geek, I needed to build a CNC machine.

I find it kind of romantic that you can create a "metal cutting robot" by watching some youtube videos and ordering off the shelf parts from your local hardware store.
Everything used can be sourced (in Germany) without leaving the house. The most advanced tool was the 3d printer to print some limit switch mounts.

The motors and lead screws are mounted on 6mm thick aluminium angle bar pieces, which are drilled in the right places.
I did not have any specific goals other than to be able to cut wood and aluminium and it should not break the 1k Euro limit. (It did..)

The software stack is a simple "grbl on arduino". I am excited to report that I already did hit some limitations of that setup and will probably spend some time to explore linux cnc. For design and tool path creation I do use freecad.

My cutting area is 715x420x115 mm. Which was basically pre-determined by the rails set I got.

So far I am supper happy, excited and learn something new each time I use that beast.


Costs: To get going and doing the first cuts: 1100,-
Now at roughly 1600,- Euro, if I am honest about it and count in cutters and "the small stuff here and there".

All design done in freecad. I basically made a rough sketch of all components and used those designs to create drill templates for the various motor mounts or z-plate.

Some lessons learned:

Next up:

a proper table with the end goal of enclosing that machine

If you made it this far, you should really take a look at my peach ass.
