"We even went trough the extra effort of closing the 2nd hole in the print head to make it extra clear."
But you left the hole in the nozzle mounting surface which is what you see when looking into the machine, or images of it. You would have to get down and look UNDER it to see you blocked off the hole for the nozzle where it goes in. And that is just a shield.
"On a product page, you usually tell the customers what a machine CAN do, not what it cannot do sometime in the future."
Agreed. Emphatically. I was simply responding to the statements about Ultimaker stating clearly that it was not further looking into dual extrusion for the UM2+. No one would have ever known by looking through the website. So, not sure where, other than buried in the forum it would have been.
"Firstly, it actually was/is on the website (or at least on the company blog):
Sorry but "company blog" is not the company website.
"Secondly, there were no statement on the website that said anything about it getting dual extrusion, it was "only somewhere here in the forum", right?"
Sure. But more like "everywhere" here on the forum pro dual. Nowhere here on the forum anti-dual. (at least very minimal and hard to find.)
"Well, it is the same with every manufacturer that releases a new product"
No, not every manufacturer. I design products for a living and many of them share when their new product is coming out. If it doesn't make the deadline, they explain just why and release the new date. It's really quite simple. Car buyers know the new car release will be once a year every year. But at least they know when and can make a decision to buy the old model or wait exactly how long to buy the new. Not a good comparison. Apple became the lead in "hiding your product till the last minute" Now many think it's a good idea. And, maybe, for some, it is. But as we can see now, probably not for Ultimaker.
"You could just contact the seller to see if you can still switch your order."
Have done that. As soon as I saw the release email of the Ultimaker 3. No response as of yet.
