UM2 Clean Z axis

Recommended Posts

Hello,

I want to know how to remove the black gunk in the Z-axis. I tried using the green grease but the gunk doesnt go away. Should i have to take the UM2 apart to clean the z-axis rod and the nut?

Attached is an image of a part i printed. I suspect that there is either Z-axis problem or X-Y misalignment.

Please advise.

I'we had the same problem with the green grease.

I have used /sprayed WD-40 on the 4 rods and on the z-axes spiral and cleaned all of with an clean cloth.

Repeat the WD-40 process several times and always use a clean cloth.

WD-40 does not lubricate for a long period – so I have applied some fine oil afterwards.

It still works fine... even after a 4-week pause.

But you will need to check your X & Y rods – that they can’t move back and forth when the printer head shifts direction.

You can find some rod/axis end cap add-ons on http://www.thingiverse.com/thing:54075
