Z-stage question...

[LePaul 312]

Now I know the left side just slides into the side...but it seems when we slide the rods down and thru the Z platform, one rod won't line up with the hole a bit. If we apply some force, the left side of the platform is popping out.

Any tips?

I got it installed....made sure the left side was on really snug....but nothing mechanically holds that in...is there anything I can/should do to make sure this does wiggle out in the future? Or will the rods be plenty of force to keep things in line?

Ok, the Wiki references a completed threaded rod. Mine has a flange (about an inch) narrow of now thread...which makes sense to thread into the coupling

However the top...the wiki shows that it is capped off like the two shafts for the z to glide up and down. My kit, there is no such thing So the top of the z screw looks like it sits a mm or two beneth the wood top piece

This sound right?

Yes, the top of the z-screw just hangs free in the air.

Where on the wiki do you see something indicating that the top of the z-axis is connected to something?

Well if you look at the pictures in the Wiki, step 6 http://wiki.ultimaker.com/Ultimaker_rev.4_assembly:_Z-stage

The picture shows it having two holes on each side for a cap to be screw/nut in

No. It should be even lower than that. Make sure the Z screw is seated well down into the coupler - make sure your set screws aren't blocking. The top hole is only so you can insert and remove the z screw. Once your z screw is installed I suppose you can seal up that top hole.

As far as the left side of the bed - yes it's designed to kind of float in and out. But I didn't like that design (or I guess I didn't understand) so instead I put shims in there and tightened it up good at the correct spacing so it slides up and down smoothly. I have had very good z travel since but it's not the intended design.

Thank you...we nailed that down. (Screws we way in, blocking...all set now)
