Received some filament and printed lots of parts in addition to previously printed parts so that the Dollo rebuild can continue. Some of the extensios were quite brittle and I had to scrap them. I think the reason is the printer I printed them with, a Tronxy X5S with E3D lite v6 clone that has quite powerfule part cooling fan. I'm running the cooler at ~30% for PLA at the moment. @ 100% the hot end heater can't keep the hot end heated and filament just doen't stick to previous layer. Probably need to lower the speed bit more...

Got the frame built during weekend. Ran out of long ties and bow ties, so printing them now so I can get the bed carriage assembled. The frame is actually quite rigid, at least compared to previous builds; the extra stiff versions of the corner parts seem to help. Also probably going to use 8mm metal rods on the beams that hold the rails.

Updated the rail holder parts a bit, now the slider is threaded and it is fixed to holder with two nuts that also center it. I'm reusing the 520mm rails from the old build so the sliders are bit larger than usual, just for this build:
