Hey guys, I was hoping I could get your opinion on a few small issues I am having before I carry on with the conversion. I managed to get the controller and mach3 to play nice and got some movement out of the Y axis of the mill. I am using Hoss's stage 3 plans, and with everything installed for the y-axis, I am getting a bit of "wobble" in the ball screw. When I set it up, I tightened the front bearing block assembly first, with the ball nut holder somewhat loose. Then cycled the ball screw back and forth a few times to try and help align itself. Then I tightened down both set screws that hold the ball nut mount in place.
I have two issues:
1. This is the best I could get the ball screw, but it still has a bit of wobble or misalignment to it. When the saddle gets close to the bearing mount block you can here the ball-screw actually hitting the bore at the opposite end. Is there a better method of trying to align the ball screw then what I am currently doing? I'm assuming the current alignment is not acceptable.
2. It also seems to me that this ball screw is pretty noisy. If you listen carefully in the video, I can hear the ball bearings moving around in the ball-nut, is this normal ? Its definitely louder then I expected. I had to repack the balls in this nut because the mandrel I made to remove the shaft failed and so all the balls came out. I divided the balls up (Aprox. 100 total) evenly and put half in each of the nuts.
Anyways, any comments or suggestions would be greatly appreciated.
