I actually wasn’t sure if the RepRap wasn’t gonna burn like hell while being left alone printing in the hackerspace but it made it’s job well and printed the whole Hilbert-Knot without any incident.
During my trip to the hackerspace I already had nightmare imaginations of what might have happened to the machine.
I was quite delighted to find out that none of them had happened.
On the contrary: I now even have figured out the optimum feedrates needed to print overhanging objects which are enough dense.
I think I’ll try to print a rainbow dash soon.
