Orbiter 2 extruder mounting for Smart effector with Magball arms

@adrian52 thanks. Wider arm spacing is generally preferred, because it provides greater rigidity and less sensitivity to small geometric errors.

@dc42 I should have done my homework. According to the reprap wiki here , stability decreases linearly with ball gap, but increases with the square of arm gap. So compared to the standard geometry, keeping the arm gap decreases stability almost threefold, whilst the 12mm ball gap with wider arms more than doubles stability. I think I was so impressed with the improvement of direct drive over the bowden that I didn't consider the effect of geometry on stability.

@adrian52 As always, great idea!
And as usual - we are waiting for the addition to "thingiverse". -
@vapvap Thanks. Posted it now

@adrian52 Thank you so much for sharing your ideas with us.
Do you do any additional fine-tuning in the firmware? -
Can anyone explain how to set this up?
With "Delta Calibration (G32)", the nozzle began to scratch on the center of the table ... -

my LGX lite direct drive mount for smart effector for my 3 kossel printers

@Fred-Y I have been thinking of that solution for my Orbiter 2.0. With my 80mm rod spacing adapter the Orbiter can be mounted horizontally.

Made some mounts for the Orbiter 2.0. Works great with my 80mm smart effector adapter. Weight is 12 grams.

@weed2all possible to get the stl ?

@PCR yes...of course...I uploaded them to my thingiverse, just click on the signature and you go directly to my thingiverse page!
