I'm working on a light-duty CNC mill that I'd custom-build out of Actobotics parts.
Worked a little on the Y axis and gantry. I like it! It feels very solid. However, I do need to get the two Y-axis 8mm rods further away from the side channels. Another change is that the Y will be controlled by a stepper outside the main frame, with a 1/4" rod running through the whole width.
This is a partial list of Actobotics parts used in this project:
