Getting a Cura Raft to stick to the object more firmly (for ABS)

Question

I have been have a problem printing ABS with Cura on an Ender 3.

I am getting good bed adhesion on the raft, but the object on top of the raft easily curls off it. See photo below.

Settings:

• Bed 110 °C
• Nozzle 260 °C
• Fan 0 % speed

How do you control how strongly the raft adheres to the object in Cura?

Answer 1

You should reduce the air gap option called "Raft Air Gap". Printing ABS optimally requires an enclosure of the printer, wind and draft cause temperature changes which could lead to layer separation.
