Mine is working great too - it really is a nice machine !!
I think the frustrations from myself and others come about by Mikini not having a traveling service/install tech. I know that would help immensely on solving a lot of these problems. It is so hard to trouble-shoot returned parts when outside the machine where the problem occurred. Seeing first hand how the machine is used/installed etc is invaluable.
I did make a bunch of copper parts over the last few weeks and that machine coupled with the right tooling leaves breathtaking finishes on the parts. I am continued to be impressed with the accuracy.
