Chatter in Y

    Is the chatter any better or worse on one side of the table vs. the other?

    To clarify: Chatter is visible when cutting in the Y (long) direction, but not visible when cutting in X (short) direction?

    Do you have a dial indicator?

      Gary,Not sure about the first part of your question yet.Don't have a dial indicator but I will buy one ASAP (Any recommendations ) .chatter is showing up in the y (long). traveling down the table. Thanks

        Any indicator with a magnetic base will do just fine.

        Usually when chatter is evident cutting in the Y, backlash in the X is the cause.

        The attached doc is one that I wrote when I worked for another OEM, the color is different, but the principle is the same.

          Gary,
          I dont think this is the backlash in X scenario. Both my router, and what is described here by Hallex is all in the Y. You can feel it vibrating as it is just transporting. The severity of vibration changes in different positions along the Y axis. Mine is the worst from about Y12 to Y36. In that range, you can sometimes feel the floor vibrating. The severity of chatter varies depending where on the Y axis it is being machined.

            Jeff...
            Does the chatter present with a vertical component rather than lateral?

            If so, and with what you describe hearing while performing a rapid move is accurate, then the solution is too complicated for a forum based "long distance "guess". I suggest that you work with tech support, they will get you a solution, but it will not be a 5 minute diagnostic process.

                Jeff, could you post a video of what is happening with your MDF. I will do the same. if we can figure this thing out I believe it will benefit all .Talked to Michel in support today he asked me to do this. He seems puzzled at this point also . I am on install till Thursday

                  I know this is an old post but I would really love to hear the outcome of this situation if at all possible. I am currently having the same issue with chatter in the y direction and severe table and gantry vibration. Also what is the spur gear that is being referred to? The drive gear attached to the shaft of the planetary gear?

                    Camaster recommended rebuilding the drives. We ended up taking them apart ourselves and just had to replace the spur gears (also called pinion gears, the ones that interact with the rack from the "rack and pinion").

                    I took apart the drives, replaced the spur gears, flattened/deburred/greased the slide plates, inspected bearings, etc. Basically cleaned the drive gearing, and replaced/cleaned/lubed worn parts, and put it back together. All was good after the rebuild.

                    We now take some wax and run it down the rack fairly frequently to use as a bit of lubrication between the rack and pinion. Hoping this will extend the life of the gear.

                      Thank you for the response. I will give this a shot. By chance have you ran any raised panel mdf doors? My issue is very pronounced on the cove and the bead profile of those.

                        We dont do any raised panel stuff, but the edge quality on all cuts is fine now, so I would suspect i would have no trouble.

                        Gears, bearings, shafts, belts. Take the drives apart and make sure all is good and replace whatever is worn. I suspect your machine will run like new after you do that.
