With all the hassle with the firmware and recalibration of the zortrax done, I'm finally printing new parts. I had to reprint the 2nd wall again, that I was previously clamping down while printing. The leg holders where 2mm too short, so I had to tweak them and reprint them, too. In general I'm missing some connection points for future parts in my designs, I think I can work with acetone welding at one point but surely like screws and nuts more.
