I picked up a micro Kinetics 1340 lathe last year, and it has some issues.

When im running a part program, every now and again a message comes up on the screen that my usb cable has come unplugged. I have replaced the usb cable, changed the usb port im conecting to on the computer, and im still getting this message.

Any ideas?

Also, and this may be related, while executing a part program my z coordinates are drifting + or - by up to .12 at random intervals.

It is not the fine control knob spinning, thats locked down, any ideas? Are these two problems related?

Do I maybe not have my turnmaster software calebrated correctly with my machine?

Any help would be greatly appreciated guys. Im stumped, and frustrated.
