Flying Extruder

Mekala

Hi
I want to make flying extruder that uses similar principels like counter weight one but ı want to use stepper motor as counter weight. I m planning to mount the stepper motor on top of the printer and bind it with extruder by string. When effector is moving arround , stepper motor will reel up and down the string by following to this formula.

√(x^2+y^2+h^2 )

x = X position of effector
y = Y position of effector
h = High of the effector
How can I do software adjustment for this ?

This is supported in firmware 2.03. The extruder doesn't have to be in the middle, it can be offset. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter#Section_Adding_additional_towers_to_carry_flying_extruders.

When you think of a crazy new feature in the ballpark of "how cool would this be..." it's nice to find out that someone not only tought of that, but already implemented it. Thanks!

Is there any real world example where this concept has been used? I'm struggling to get my head around additional towers..

There might be some interesting info here and here.

Here are three. Two use the additional axis to carry an extruder, the other uses it to carry a camera.
