CNC Truss

This is a modular gantry style CNC Machine.

Here is the assembly manual for it:

The GRBL settings are provided in the file "grbl settings.lbset". This is a Lightburn file. You can open it with a text editor as well.

This is an inexpensive, DIY CNC machine. It cost around $1k CAD to build the machine, all inclusive excepting a 3D printer and some basic tools. The laser it's running (Opt Lasers XT8) cost about $2k CAD. I'm happy with the performance. I'm working with full 4 x 8 sheets of plywood.

Here is a video of it in action:
