Greetings everyone! New guy here. I've been following the group for

I imagine that gear backlash can be measured and if its not captured by an
encoder on the geared down axis, it should at least in software be
considered for every change of direction. Is there such an option?
There is:
This is just a quick bugfix release for a silly bug that made it into
the Axis GUI in 2.7.0~pre3.
This release fixes a bug in the Axis GUI when transitioning to
world-mode, on non-trivial kinematics machines.

Thanks to everybody who replied so far for the rays of light! Maybe I
should admit that I have difficulty to imagine the algorithm to translate
from 3 linear axis of a delta printer to the 'euclidean' 3d space that the
model will be printed in, therefore I also don't really begin to guess what

I definitely have to agree with that,
