Hey Harri,
OK, the linear bearings feel good. After the new ball screw, it is tighter (harder to push) than before, but I attribute that to a nice snug ball screw.
It really does not matter where on the table it is.
I have downloaded all of the manuals I could find from meau.com on the servos and drives. The drives are MDS-A-SVJ10. I forgot to write down what the servos are when I had it apart. Are yours the same?
If you could email me a PDF of your manual, that would be great! At least the part about the tuning, I would be forever grateful!
I noticed a few things that were HEX, that didn't make any sense. Most of it that pertained to the drive setup, was not. The one I was looking at was only 4 digits long (set to 4400) and it said in the manual to change the 5 bit to a 1. Where the heck it the 5th bit? So I got a little lost there and decided I didn't want to mess with that one too much. I did go through the setting procedure in the manual and it really didn't help. It said, if you are getting a bad finish on 45 deg angles, to turn up the gain until it vibrates and then back it off. It didn't work.
You mentioned feedback. A buddy of mine was wondering if my power source was causing some issues. I have 240V 3 phase with a wild leg. Mori told me that is not a problem, just put the high leg on L2. None of my other machines have a problem with it, so it shouldn't hurt, but what do you think?
One more thing, is there a way I could get you to jot down your 2200 series parameters, just for comparison? Did you have to tune yours, or did it just run out of the box?
Again, thank you so much for your input!
