Clearance / Tolerance on Print in Place Model or any model fits perfectly with each other

[csl0304 0]

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.

There are some settings which you could use to fine tune to get better results for that objects.

 

You could try to:

• Set "Slicing Tolerance" to exclusive
• Set horizontal expansion to a negative value
• Set Outer before Inner Walls
• Reduce Flow a little bit

I am sure there are some more settings, but try one by one and check the result afterward before changing the next one.
