had a chance to test thing under power. the z axis makes me gigglei thought it was going to be slow since it was a direct drive but it surprised me
the cross axis did about as good as i thought and the long axis was not that great because of whip. so i have been working on a solution to that problem to get better results. the central drive makes things tight so any kind of driven nut design would not work well with what i have and another method that requires a linear rail would add more cost to an already over budget build
so i came up with a guide / whip dampener that allows the central drive beam to pass under it. did some quick testing today after i did some more work on the entry and exit ramp piece and ran things up and down by hand and everything works really well at that level. so i feel good i am onto a cheap solution that will do some good for the machine.Attachment 438216Attachment 438218
