Looking at one for sale here but it keeps getting a "emergency stop or limit switch encounter" and you have to reset it.
When you hit jog all is still good till you try to move XYZ.

I have checked all the limit switches and even tried unplugging the cables from the board. I do not here any noise when I hit the E Stop button. Shouldn't there be some noise?

This machine is pristine and was used to make wooden parts. All the flaking is still on the ways and the bed shines like a mirror. It was making parts, unplugged and moved across town. Cleaned off the wood dust and now this.

Any ideas?

Looks like these were made in Louisville, Co where I live by Colorado Numerical Control Corp.
