[Hardware] Print density and flex

[Joco]

In my experiments with testing the movement of the axis I have seen flexing in some of the plastic parts.  Nothing dramatic but its there.   Is there any guidance or peoples experience in how dense to print the parts and what infill pattern gives the best results.  I am particularly interested in the variables that give the best results on the tall left/right frames supporting the X axis.

Also has anyone experimented with extra bracing on the outside of these frames?

Yes I know I could just up the infill to a very high number but I'm not a big fan of brute force solutions.  Unless its more power for my gaming rig.  In that case there can NEVER be to much power.      :-)

Cheers.

Sorry for the late response!

Martin did try some extra bracing for the frames, using aluminium sheet - milled with Cyclone:

Cyclone 2.0 has thicker frames, and that should be enough for our purposes. I printed them at 20% with the reticular infill in Cura (more is better of course, as plastic is quite cheap).

I think the small flexing shouldn't be a problem: the machine is quite slow so lateral forces aren't that significant.

Cheers,
Carlos
