I used to have MakerBot printer and it works perfectly with mostly all print in place model (Lefab Makerfaire Robot https://www.thingiverse.com/thing:331035, Platform Jack https://www.thingiverse.com/thing:925556...etc). and when I use my UM3 and UM s5. The parts all fused together. I was wondering whats the setting at cura cause that.
