All the parts are their, but if you're expecting to be able to put this to work right away, look elsewhere.its actually quite well thought out overall, but the cost cutting shows itself.1. metal debris, there is tapping, cutting, milling shrapnel all over it.2. all threading needs to be re-tapped, and cleaned. all fasteners included are chewed up and very rough.3. mounting holes on the movement itself, is not setup for universal mounting, expect to tap new holes if your expecting to use this vertically.all said, its very solid overall, decent value, and accurate. the stepper has plenty of power. but unfortunately it takes a lot of work to get working smoothly.
