Hi every body. I have a 2000 3016L that has a very noisy x axis. Sounds like chewbacka from star wars! So far I have tried tuning the x axis amp. That did no good. Then I tried switching the x and y amp boards. That still didn't change anything. Also, I did NOT have any noise from it till I changed to the new style couplers when I put new thrust bearings in the bottom end. The guild ways look fantastic too. Has any one else had this problem??? I talked to a fadal tech and didn't have any luck there so I figured I would try this.
