Excessive Chatter on Z Axis Movement

Post by seaton »

G'day one and all,

I've just received my new v2 Printer and spent yesterday assembling it, all is now working (woohoo!) however I'm getting excessive chatter manifesting itself as a screech whenever the Z Axis moves. I put it down to no top end support on Z Axis Drive Shaft (see photo), If i support the shaft while its moving the chatter disappears. Now it looks as though there should be some support as the shaft is machined, and from what I can make out in the drawings there appears to be a support, however, there was no instructions to assemble, and no part supplied so I'am wondering if it is indeed part of the v2.0 design? Are other v2.0 owner having this problem on the the Z Axis?

Regards

Stephen..

Did you put any kind of lube on it? Teflon spray should work just fine.

just a follow up on this problem.

The chatter kept on coming back after I lubricated it every couple of days. Today I replaced the Z-Axis due to the heat damage, and this fixed my problem. The new printed part had a little bit more leeway for the Z Axis Nut as from the old one upon examination the screw as rubbing on the side of the hole ever so slightly.

Now its as it should be

I recommend using bearing grease for the Z axis, light oil does tend to run off or evaporate quickly. And you can also use the same grease for the Hiwin rails. Around here, not all hardware stores have the grease in small containers for use on bikes or cars, but many do.
