'Z' doesn't sound good

If I hit this problem in the 'Y' is there something to adjust there as well? Too bad Taig doesn't send a nice little manual with their machines and a troubleshooting guide. Thanks -Ed

As far as I know just the gibs. I have a bit of a whirr on the X, but only when I jog though and when the table is far to the left (maybe the last 3rd of travel. This may have to do with screw and nut wear and the nut being a bit tight where there is less wear but Im not posative. Maybe inconsistancy with the screw.....Or caused by the added leverage of the weight of the table hanging off the end. I dont really have an answer. I have never found a cure for it. I think it does it less though when I loosen the nut a bit but then I open backlash up a bit. So what I did is find a happy medium between the noise and limiting backlash without it binding. But like I said I only notice it when I am manual jogging, When it is cutting or rapining it is either muffled by other noises or does not exist at the slower speed.


My Y is silent but it is a much shorter travel and has a much more centered gravity than the X. And as we learned the Z as well. The Zhas an issue that the X and Y dont as it hangs off its slide and doesnt just rest on it. Thats why if things are a bit loose you get that issue you and I had. "smooth on the way up but rides against the bottom edge of the saddle on the way down"




Ok I change my first statement the gibs and the nut could cause it. I know when I tightened up the Y as well I got a whirr if I went too tight. Other than that I dont know.

I had to laugh when I read Jeff's suggestion about a night owl forum. When I lived in the Chicago area about 30 years ago, my dentist would show up at 3 am to work on car projects with me. We figured out that noise of "thinking gears whirring and grinding" in our heads would wake us up, and cause the problem. Our wives both thought we were nuts. We ended up completing the restoration of my '60 Vette, and after selling it, the condition healed itself....until I got into Porsche restorations.
