I'm in the process of opening up some some space in my shop and have decided to part out my CHNC I. all parts will be sold supercheap mainly cause I need the space. feel free to ask any questions. when I purchased the machine I was told that the servo on the Z axis was bad. I have never powered up the machine so I cannot guarentee any electronic parts. the machine did come with an extra servo motor that appears to have been rebuilt by a shop out of Minneapolis MN.
