Implementing a 4 axis config
-
Hi!
As said on reprap forum, I plan to add 2 axis on the bed: A (X // rotation axis), and C (Z // rotation axis), in order to be able to print on a sphere.
Such kinematic is non-linear, as Delta or Scara are, so I guess I have to activate the segmentation feature, which, if I understand, split one long segment in several small ones; Am I right?
Where does this segmentation usage defined? In other workds, how is the right constructor called, and from where?
Thanks,

Currently you have to create additional axes in the order U V W A B C. So your axes will be U and V.
You can add additional linear axes to existing supported kinematics without changing the firmware, but to add nonlinear axes you will need to define your own Kinematics class in the firmware, deriving it from either the base Kinematics class or another of the existing classes. One of the options you specify is whether you want segmentation applied or not.

Forgot to say that my printer is a CoreXY. So, it uses 5 motors…
-
I started to implement this kinematic, and I have some questions.
But Is it the good place? I didn't find a sub-forum dedicated to devs…

Good point about the sub-forum, David would you prefer a "Dev" forum or for developers to use github to discuss work on features?

Let's have a Firmware Developers sub-forum. I'll create one. Edit: I just did that.

Good! Is it possible to move this thread in this new sub-forum?

I don't know how to do that, but I think Tony does.
