  1. Big announcement! [German version] [French version] [spanish version] Hold on to your seats. It is not every week I can make an announcement of this magnitude. In a few weeks time Ultimaker will migrate its forum to a new forum software, provided by IPboard. For some it may be a surprise, for others it may be a decision overdue. Nonetheless we are happy and confident that this is the best decision we could make to provide a healthy environment for our community and ensure a bright future. We are aiming to migrate mid-December and do the complete the migration in ~3 days. Some parts of the preparation are still in progress, so the exact date may change (if it would get too close to the holidays, we might decide to do it early January instead). In any case, we wanted to share this prospect with you ahead of time. Make sure to like or follow this topic, so you will be kept up to date about possible changes and there will be no unpleasant surprises. Migrating means there will be a period of time that the forum will unavailable for contributions. In order to migrate all content, we have to close it down, bundle everything and deploy it in our new environment. We are looking into keeping the forum available for searching but no new posts can be made. Or perhaps have a designated chatroom available to bridge this period. Obviously we try to mimic the existing forum as much as possible for a smooth transition, however it is inevitable some things will work and look a little bit different. We’ll do our best to make the introduction as easy as possible. Why IPboard? A little while back I invited some of the most active members of our community and Ultimaker to help test different types of forum software. Among others we tested vBulletin, phpBB, IPboard and we looked into Vanilla and Discourse. After some thorough testing it was pretty clear that IPboard won the comparison with a landslide. Why migrate to a new forum? There are a few different reasons why we think it is a good move to migrate to a new forum. For starters, there have been some bugs haunting the forums which have proven difficult to fix. Some of these bugs have been more intense than others, regardless, they boiled to a point where they (could) harm the user experience significantly. Obviously, that is the last thing anyone would ever want. Secondly, when we moved to our existing forum we had big ambitions to build a collaborative forum where users would gather and ignite projects together. For example, in the user tab you could look for users with certain skill set, to potentially invite to your project and many interesting projects would surface from our community. And indeed some have, the Mark 2 project being one of my favorite community projects. But we don’t feel that vision still matches with our community, with knowledge increasingly becoming more important. The Ultimaker 3D printers becoming more advanced, a better ‘out of the box’ experience will take over a lot of the questions originally asked in our community. At the same time, that is where it gets interesting! After the ‘out of the box’ experience and your first handful of prints, you want to go and explore what you can really do with 3D printing and the Ultimaker ecosystem. And that is where the community shines. We have so many product experts in our community, it is unbelievable. That is also where we want to focus on in the upcoming era, educating our community further. Of course, we need a healthy, cooperative and supporting software environment to do this in, so the migration is step 1. If there is anything you want to learn from us, make sure to let me know! Can be about CAD modeling, post-processing, materials. But more about this, in our new forum As always I’m curious to hear what you think. Make sure to follow this thread so you will be kept up to date when things get more clear further down the road.

  2. It is tight to the libraries you are linking with. The old Marlin of the old UMO needs the old Arduino I haven't compiled an UM2 firmware recently, but I believe the core hasn't changed much, so I guess you should try with Arduino 1.0.6 -- That's what I am using for the UMO.

  4. hiya I would agree with GR5 on this. I have a UM2+ too and never had this problem as such. If the above solution doesn't work I'd heat the nozzle to about 215 at the most and manually push it through. I might be that the nozzle isn't hot enough to melt the remaining ABS. (unlikely but who knows) or just load it as ABS and once pushed though change the material type.

  6. So when ordering a Glass plate is important to ask the reseller the ship date of the stock glass and to avoid old stock.

  7. Hello Migo, I'm not a expert but i work on a new design in Dual Extrution the Dual Balance system. At the present time this system work well on a ultimaker 2 and there is some advantage: 1 No need to had other eletronics 2 No need to had other Power supply 3 using the same firmware of the ultimaker original Dual 4 The nozzle who is not active have a special Z level (-1.5mm) in order to protect the already printing things. You can find some test here : https://www.thingiverse.com/thing:2644923 Now i works to change the 12v fan with only 7 mm of thickness. I don't know the ultimaker original but as mentioned neotko you need to change some things. May be you can find some examples to upgrade your ultimaker original in dual Extruder mode.

  8. You might want to reconsider Ultimaker glass plates. In the beginning of this year, we have improved the specification of the glass (flatness), and improved the quality control at our supplier. Glass plates in our sales channels should be improved/good now. Some background: Float glass is very flat to begin with. It is then cut to shape, it gets c-edges and the corners are rounded or dubbed. After that, the glass goes into a tempering oven. In this oven, the glass is transported on rollers. It goes back and forth in the oven, because if it would lie still, the shape of the rollers is imprinted on the glass. After the high temperature treatment, the glass is rapidly cooled. This causes high stress between the outside layer of the glass and the inside. This makes the glass stronger. Unfortunately, there is a practical limit to how flat you can keep the glass in the tempering oven. So there will always be some remaining unflatness. I'm convinced that our glass plates are now flat enough to ensure a good bed adhesion on the whole bed. Of course, you still have to follow all other instructions (clean plate, use glue, use adhesion sheets, ...) to maximise performance. (see ultimaker website). The Neoceram glass that is mentioned in this topic has a flatness specification that is much worse than the glass that Ultimaker sells. Of course, it is usually better than the specification allows. But in the beginning of this thread it was claimed that the spec is very good. That is not true. (the D in the specification was mistakenly interpreted as the thickness, but it means the diameter of the glass)
