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.
Spot on about the Z-axis being the critical point of failure in most DIY CNCs - harmonic resonance at higher speeds will absolutley kill accuracy before anything else.
