Ultimaker 2 documentation disappeared?

[Perchik 2]

I needed to align the axes on the UM2+ and I've done this before. I remember a page on the ultimaker website that described the order of tightening the set screws on the pulleys, which I can no longer find. I'm also unable to find the page about checking the tension of the short belts. 

 

I can probably make up both of these things, but I'm wondering where all the documentation went and which other documentation is missing.

Ooh, update. I found a link to https://ultimaker.com/en/resources/50870-check-the-tension-of-the-short-belts which no longer exists 😞

Ah in case anyone else needs it:

https://support.ultimaker.com/hc/en-us/sections/360003548499-Ultimaker-2-

 

 

As far as I can tell, these are harder to find now than they were, and all the old links no longer work, but the info is still here.

Hi Perchik,

 

Welcome in here!

 

The short belt tension method is here:

 

https://support.ultimaker.com/hc/en-us/articles/360011802500

 

Here is a procedure for the adjustment of the two 6 mm shafts.

 

https://ultimakernasupport.zendesk.com/hc/en-us/articles/115004168943-Aligning-the-Axes

 

 

Side note:

 

Adjustment tool (you need two each) for 8 mm to 6 mm shafts to make fixed distance from the 8 mm shaft to the 6 mm shaft.

 

Here is two different tools and there is more of them out there..

 

Just print two of the one you like and use them to adjust same distance at one side, tighten the pulleys and check that they also fit at the other side without any adjustment on the other side.

Do the same for the other axis. (This is based on that the frame of your UM2 is perfect.)

Good luck

 

Thanks

Mm... I can no long find official links. Ultimaker team might think it is unnecessary to adjust axes after testing a lot of UM2/UM3 for years. But I think it is still useful to ensure the axes of my UM3 are perfectly aligned.

 

I ever sent my UM3 to reseller for ER18. After the machine is repaired, I used it for several weeks but feel the prints are not as good as before. Until, someday, I found the 6mm shafts are not well assembled to the 8mm shafts.

 

To repair ER18, reseller has to disassemble the printhead to replace one cable. The two 6mm shafts must be removed from the 4 U-shape slots. After repaired, the 6mm shafts must be pushed into the 4 U-shape slots to fix them. But, the shafts were only pushed to 1 of the 4 U-slots. So, all the shafts will "bend" when the printhead is moved to edge of bed.

 

Yes, we just can NOT fully trust reseller for maintenance. In fact, I don't blame the reseller. It takes a pretty long time to learn all the knowledges for 3DP. Experienced employees might leave company and new (unexperienced) employees will make mistakes.

I'm still trying to find the documentation that previously lived at https://ultimaker.com/en/resources/19953-aligning-the-axles . Anyone happy to know where this page is now ? or have a cached version?

Hi Perchik,

 

There might been a revisions over time, also this web site is changed as well.

Maybe @SandervG knows where this document can be found.

 

Thanks
