Printrbot Jr. Z Stabilizer by LscsDegings Mar 9, 2013

Description

If your layers are giving you trouble, try this.

EDIT 03 10 13
As brought up by reeseallen, this item is not to take out Z free end wobble.
Also, there is no substitution for proper care and maintenance of your printer. YMMV

Thanks!

Worked very well for me. thanks!

This is true only on a perfect machine. Wood compress over time and slowly reduces the tight tolerances. Or, a larger issue, bent thread rod.
This, I my case, translated into head wobble and Z layer pattern. There is also more going on than what the picture shows.
But you bring up a good point. This is not for a new, properly set up machine nor is to take out Z free end wobble.

I hate to be the bearer of bad news, but this is actually a counterproductive modification. It over-constrains your machine and imparts unnecessary radial stress on your Z-axis stepper motor and bearings. The four Z-axis bearings do all the work of linearly guiding your
printer's Z-axis motion; the screw's only job should be to push the sled
up and down. If the end of your Z screw is wobbling around, that is not a problem, and it should be allowed to wobble freely.
