This can easily happen if the printed gears are not perfect. You also could play with your Slicer-settings. After some trouble like yours the Amsterdamman's gears work fine for me. Do you have a bearing at the top side? This could be a problem, too.

Slic3r provides an option exactly for this, but you will need at least version 1.2.9

I use Sot's (thank you!) taller mod of the original, not perfect but better than the original IMHO
[forums.reprap.org]
There's an extra lower nut for support of the threaded rod, both nuts is in-bedded in the gear so cannot be tightened against the gear, also had to slim down the lower nut or it would drag against the screw holding the supporting bearing, but it works well and runs straight
If you chose to use this mod I would recommend you drill out the upper nut to 5mm, this way you will be able to tighten the extra upper nut against the gear wheel

Hi Erik, these look good, but dont they remind a lot of the original ones that came with the printer in green color?

I replaced them first cause I read on many threads that they didnt give as much precision as did the herringbone gears.
