[Solved] Haydn arms interrupt part cooling fans

[toskium]

Hello everybody,

I am facing a bit of a problem with my smart effector and the attached part cooling fans.
I have two 24V radial blowers connected to the part cooling connector, they work flawlessly when the smart effector is not connected to the Haydn arms but as soon as I connect both arms on the part cooling fan side that fan stops spinning. The second one stops as soon the other two arms are snapped on.

This is the fan I am using: https://de.aliexpress.com/item/32798634077.html
The smart effector is a genuine unit.

Do you have a 24V radial blower recommendation that doesn't fail when the Haydn arms are near?

Thanks!
Markus

@toskium does that happen if you try reversing one or the other of each pair of arms?

@T3P3Tony oh, I didn't try that. Let me check

Thank you very much, you are my hero!

The grip is probably stronger that way too. It's mentioned in the Smart Effector assembly instructions that you should alternate N and S poles around the effector.

@dc42 you are right, that slipped my mind, my first delta printer and there is so much to learn. Thanks again!
