It is really cheap kickstarter out of China. Cuts Aluminum and Brass, there is even a demo cutting stainless, really slow.
Tool changer, lasers, 4th axis option, dust collection, height probe, ball...

There is absolute position data, that is how it knows where it is. I think the wheels do not contribute to position calculation at all.

The unit weights 22lbs. I'm not sure what kind of cutting...

From what I understand, it isn't a problem if the wheels slip, it is a closed loop. The positional feed back is continuously used to correct for slippage.
They also say they haven't had a problem...

Saw this some time ago and they launched on Kickstarter. Interesting idea. You only need the space for the 'machine' when you are cutting. Thoughts?

I'm looking for a quality MT2 chuck for either ER25 or ER32 collets.

I have a Hong Kong one, but I'm looking to get something of better quality.

Thanks for your help and suggestions!
