Hey everyone,
I am in the process of converting my G0704 with bdtools mounts and linearmotions2008 ballscrews and nuts. I was running the Z-Axis today with just the slide and no head yet in an attempt to verify a good range of motion. It was running good but started to bind when it reached near the top of its travel, I included a video...can anyone identify this sound?
I ended up popping off a coupling because the slide was bound up and the stepper was still driving the screw and it ended up loosening the chinese jamnut and the acetal disk popped out once the lead screw dropped.
I then loosened the Z-Axis mount from the column so that I could see where it "naturally" wanted to be when it was at the top of its travel and it wanted to tilt the mount forward which leads me to believe that the Z-Axis ballnut mount that bolts to the carriage is too tall and that I need to machine it down some.
I am including a picture of this problem and a video to hopefully identify the noise.
Does anyone have any experience with this issue and know how to fix it?
Thanks a bunch!
