Here is my Project A CNC 3000 mm by 1500 mm, with a 2.2kW spindle collet ER25 and 4 stepper motor nema 23 425oz-in. The purpose being to have a large work surface for a minimum cost.

This project is an adjustable router guide template made with 20x60 V-slot. It was meant as a less expensive and more user friendly alternative to commercially available units.

more to come, please follow along the journey!

Cut Area: 825 x 1340. Max Cutting depth: 2 inches. Arduino based control with Nema 23 and Nema 17 drive. 8mm leadscrew and 2GT belt drive. 400W 48V quite cut spindle.

I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?
