Hi Folks, I may have missed it but my instructions for the Ultimaker Original + didn't seem to mention adding belt tensioners. I have them but I'm not really sure how to add them. The only belt that seems to have an issue for me is the short one (vertical) that I believe controls the y axis movement. I can't see how I could add a tensioner to that belt because it looks like it would interfere with the range of movement. Anyone have any thoughts on this? Thanks in advance, Kevin

After reading about this with others I realized I really just needed to hold the gear (and it's cover) tight and tighten down the nut...I did this a couple times after letting it run for a bit and now this problem seems resolved for me. If not I'll put some loc-tite on it but for now I think I'm in good shape.

Thanks for the replies folks...VERY helpful. Peetersm yours showed exactly what I was looking for. Turns out I did end up cutting something I wasn't supposed to. I bought a couple connectors and crimped them on so now my heat bed works. I hope this thread saves someone else the headache.

I have the same problem with my ultimaker original + that I just finished. The natural motion of the motor...unscrews the nut.

Hi, I'm at the end of my build and the instructions don't show where the wires connect to in the electonics. This should be mostly simple to look and figure out but the instructions say things like "plug in the blue and purple wire...for the fan" and I don't have a blue and purple wire...so I'm guessing it's the black and red one because I can see a little black and red wire coming off the fan. Also, I cut the connector off the end of my heat bed wire because that's what I thought the instructions were saying to do...and now I'm reading a part that seems to say I need to "plug" them in to the other side of the board. If that's correct I cut the connector off already so that will be yet another trip to the store to try to fix something else. If someone could please post a picture of their working print electronics that would be terribly helpful because it would take me about 2 minutes to see where all the wires actually are supposed to connect to. I'm pretty frustrated at the quality of this kit at the moment. There are a lot of missing items (as many have mentioned) and there are also parts of the build instructions that are wrong (as others have mentioned). I'm sorry my first post to this group is so negative but I'm really feeling like I should at least have the correct and high quality build instructions for a kit I paid $1,500.00 USD for.
