I would start with a delta, because they are simple to design,
3 symmetries, once you've developed 1-axis ...
you're done
as regards the precision of the delta should theoretically be very accurate if:
- The frame is very stiff
- there are no inaccuracies in the construction and assembly
- Very low backlash in the joints
of course it is not easy to get all this
The reason why I want to realize it and design it by me is that I have not yet seen a delta that I really like and want to make.
Many of delta frames that I see around with high aluminum pillars and connection beams only on top and bottom are very few stiff
Also those delta with parallelogram made by carbon fiber with a diameter of a few millimeters are very undersized in my opinion, it is true that they are very light and have little inertia, but they are also very flexible and will never be fast and accurate at same time.
I prefer to have a precise machine, even if slow.
The parallelograms made of tubes aluminum or carbon fiber are a good choice, but I hate rod ends because they have working angles very limited.
The magnets seem to work, but do not give me confidence.
Some time ago, I started to design my delta, but I'm still very uncertain on how to make the parallelogram and if I have the right idea I could even try to do it.
Otherwise reconsidered the idea of a Cartesian printer, most likely a core xy.

I read a lot about the configuration of the firmware of the delta, and having done the project with a CAD , I should not have a big problem to obtain the geometric data
I have not yet figured out how to configure the slicing ...
but I decided to do it later
Do you have some quick info for me? :-)
