Adaptable lower anti wobble

If you want to use these parts, I recommend also printing these other parts that were created by DAL:

• Adaptable superior anti-wooble:  http://www.thingiverse.com/thing:1240175
• top guide threaded rod: http://www.thingiverse.com/thing:1260449

An these ones: http://www.thingiverse.com/thing:1738716

This part replaces the official anti-wobbles of the Dagoma Discovery 200 which were too flexible and had too much play for my taste:

The official plate not being flat, the 4 points of the probes realign a theoretical printing plane... and this results in backs and forths on the Z axis during the printing of each layer. These back and forth movements are transmitted in Z by these anti-wobbles.

These new parts are more rigid and allow the fork spacing to be adjusted.

Configuration A: (see the first two photos): the fork spacing is adjustable (M3 screw length 16 mm + nut). In this config, I - initially - placed M8 washers between these anti-woobles and the Z carriage, and tightened the spacing of the forks leaving sufficient clearance so as not to create too much friction.

After several tests, I noticed that using washers was ultimately not a good option because they sometimes slide horizontally and therefore rub on the Z rod, generating friction... so I removed them and since then it's been nothing but happiness...

Configuration B (see the last two photos): or these same holes can be used to pass plastic serflex in order to press the forks against the X carriage.

Configuration A gives me complete satisfaction today (less play, less wobble, less noise).

How I Designed This

Made on Solidworks with the help of NetFabb Basic

I measured the original STL file from Dagoma with NetFabb Basic, then I have made a new design with Solidworks
