Assembly printhead Ultimaker 3ex

[Arcon 3]

One of these days there was an incident with my ultimaker 3. It was my fault. I had to disassemble the printhead to clean it. Where can i find instructions for assembly printhead. Thanks!

I don't think an assembly manual is publicly available. @sandervg any change you can share something?

I think the mechanical parts a pretty self explanatory, screw the metal bottom plate to the top plastic part first, so you can drop it into the bottom plastic part.

Put some (green) magnalube on the small mechanical switch parts, then the little metal bush goes on top, the spring goes on top of that.

The thing I'm not sure about is the order of the connectors to the electronics board, does the board have labels on it? maybe someone else can pitch in...

Then put the hole thing together with the bearings in it, and screw together with the 4 long screws.

Just very important. Don't overscrew the board that goes behind the cores, or it will make a contact error. As a general rule, don't overscrew anything.

Thenonly semi complex part is the plastic that has the little spring on top. Try not to loose it since is quite thin and jumps a lot

I do not remember from whence is that spring.[/media]

The two ç shape plastics, one goes on top of the other and on top of them the spring. Is what makes 'lift' the second core. The metal tube goes on the upper plastic of the head and fits inside the spring.

Sorry I don't have my printhead here to show you :(

I did assemble/ disassemble it quite a few times.

Hey moderator, as you approve this reply, please send a message on to support to either develop documentation on assembling these things, or make that documentation discoverable for your customers.  Thanks!

I think Ultimaker relies on the resellers to help you on things like assembly instructions.  Your reseller should know where documents like this exist.
