Right now all it has is a plotter adding but I'm also making a mount for a mill and lasercutter. It's meant mostly for making circuit boards but should be able to handle other projects as well.

It's designed in FreeCAD and some parts were sourced from discarded laboratory devices from my job as well as a broken 3D printer.

Here's a link to the FreeCAD in its current form. I'm not happy about Google but this is to be shared for free so it's okay.

Right now it's a bit messy but I intend to post it to printables.com later when it's fully done.

The video is sped up 8x. I think it can handle this speed realtime as well.

Nice to hear! At the moment the spindle, if it has the right to be called that, is a 775 motor with a chuck attached to it. Which is good enough for circuit boards and wood. Perhaps aluminium is doable as well as long as the feed rate is kept slow enough.

Should milling steel ever be on the table I'll make a larger machine and will use leadscrews on X and Y instead of belts and perhaps dual Z motors.

I've also designed the build around materials that were readily available such as the 18mm X rails. Apparently they're quite obscure since they aren't sold on typical Chinese webshops.
