I don't recall your drive versus driven pullies, but a 2:1 ratio would keep torque reasonable for NEMA 17 motors, I think (given probable axis weights).

According to many posts over at CNCzone, this was true until about 5 years ago. Apparently the new inverter controls of the best systems can produce results on aluminum that are very clean with no slag using only air. Accuracies down to .003", which approaches that of laser and water cutting.
The model that Bart has purchased is among these newer types. Perhaps we will soon start to see videos of his cuts. It took me a few months to get my laser "dialed in" to be satisfactory on every type of material. I'm sure Bart is going through the same thing now as he jumps between his many projects.
