I found this printer available (hardly) used for a pretty low price (similar to cheap chinese DIY kits). It is apparently the result of a Danish university collaboration/ start-up called “Create It Real”. They produce a special mainboard and provide a special slicer ( https://www.createitreal.com/technology-software/ ) for it.
It seems to have been superseded by the WT280X though they appear identical.
I found some videos here: https://www.youtube.com/user/CreateItReal/videos , but cannot really find any reviews (i think i found one of an earlier “not speed” version, but that uses a different slicer and a different mainboard, so is not really a good indication). It sounds like it is a combination of the new mainboard with stronger steppers.
I am considering buying it for fun, but don’t like buying blind.
