The second desktop CNC I made. I wanted to build a more accurate and robust machine compared to the first without blowing the budget. I decided to use profile aluminium sourced from a local supplier to ease construction. This stuff is easy to use, almost like playing with legos. The profile has grooves to allow for special mounting pieces to be used, which makes 90 degree joints very accurate and strong. As a bonus it also makes holding down pieces for cutting easier. You can use standard wood clamps, or make your own (like I did).

I’m a bit lazy to go into the construction in detail like with the previous machine, but hopefully these images and their description should be enough to give you a good idea.
Some difference worth mentioning compared to the 1st machine is I’m using a Proxxon tool instead of the Dremel because it has constant torque control. The other important change is adding a fuse box, after burning out a dremel and a previous Proxxon tool …. ouch!
