Was about to get a toy- then I did some research...

Here we go again.! . . . Have you ever built or used a belt-driven machine.?
For a small router, (or even a basic large machine) then belt drive is a very good solution with high efficiency and low backlash that's reasonably cheap and easy. Yes, maybe not ball screw good but much better than other methods like R&P or cheap lead screws if done correctly. . . . .Don't knock it until you've tried it.!

Here we go again, my first machine was belt driven and aint nothing bad with it, just learn how belt stretches on each material and each temperature... Of course you will say if properly calculated will not happen and i will tell you that for same price it could be ball screw.

Why don't you relax and stop supervising me what i say, it's just an opinion. I am not pretending like you to be the final word on everything
