UMO extruder wheels dont meet ?

Recommended Posts

Hello,

I took my old ultimaker one out of the box and wanted to try out a new print.

I dragged out the old filament and put in new one but now the two wheels of the motor and the extruder dont meet anymore :-(

Did I use too much force ?

What should I do ?

Ive tried to push it a little more towards the motor wheel but it doesnt buldge and Im afraid to break anything.

should I take it apart again ?

also the little black thing on the other side fell off I think this kept everything in place ? 5a333b5ce5893_ScreenShot2017-05-29at13_32_06.png.a482fb91c4b8b361e01adcf87f1a8e6d.png

What should I do If anyone could help that would be great Thanks !

Yes indeed, without this retainer the big gear will slide out of the printer. You can replace it with an E-Clip of the appropriate size or print or mill a new one (which will be a bit tricky in your situation) -- This is the part...

Thanks Amedee !

I still have that thing. Do you maybe know what is the best way to put everything in place again ?

Should I detach everything (hope not) ?

Ive looked at the manual but its a bit hard to understand what to do from that.

Thanks for your time

Unless there is something I don't see, it is rather simple -- nothing to take apart.

Open the filament feeder part, so everything is free, than just push the main gear in place, when it is fully pushed against the wooden part, the groove on the axle should be flush on the other side and that's where you put the clip.

If the groove is not flush with the wooden part, you will have to add/remove shims.

If the gear is no more secured on the axle (unscrewed) that's another story, but let's confirm what the real issue is first.
