I'm beginning to wander if it is just me, or if the or something. Several times I have ordered replacement parts. and they have sent me the wrong ones. I have a inch mill and lathe but they keep sending me parts for metric. This last time they sent me the new backlash nuts for a metric but under the part numbers for a inch. Now my plans for use of it this weekend were down the tubes. Like I said this is not the first time. Also their Quality control seems to be lacking as I have had several things that are not finished properly. I've had T nuts that would not fit into the slots, without threads, even ones that are not blued in a package of ones that were. Then you had the nuts for both the X and Y axis that I just got, (oh by the way they were in the same package as the new backlash nuts and they were inch) had machining that had chatter marks etc on them. Is this just me and my bad luck or is this what the company has become as of the last couple of years.
