Which rod goes with which axis?

[Lemma 0]

Hello UM community,

I just bought a UM2 on eBay and when it arrived both rods holding the printhead had detached, I noticed that one is slightly longer than the other.

Which axis does the longer rod go with? Front/back or left/right?

Thanks!

Hi,

and welcome to the forum.

I don't remember which rod goes where, but you can check the assembly manual. It is mentioned there for sure:

Can you not just hold them in place inside the frame an check? it should be fairly obvious...

They both fit in both ways.

The X is the shorter of the two, as verified in these two documents.

I assume the X axis is the left/right one based on what I see in Cura and common sense?
