<p>Looks like you have 20x20 extrusion and you are still seeing flex? I noticed after going to some super strong(N52) magnetic linkages that I have considerably more friction in my setup that results in my OpenBeam 15x15 extrusion having visible torsional flex.</p><p>I think my next delta is going to have 20x60 extrusion with Igus T linear rails for ultimate rigidity :)&nbsp;</p>
