I finally could go to BUDA::LAB in Kortrijk for the Ultimaker workshop organized by Timelab Ghent. BUDA::lab has put some picture on facebook, check their Ultimaker building weekend album. It was a fun weekend and I managed to build the machine without any problems. Couldn't have done this alone though (well I could have, but it would have taken a lot longer). Thanks Björn, for helping me building the machine of our future.
