Answered Model slips on bed

I'm new to this and just bought my R1+

I've been able to print off a few basic models and all is fine, then went for the big model test, being a house model.

I've used the tips and tricks when the first model slid around the hot plate barely after it printed a thin layer of the slab.

I sprayed the plate with hair-spray, tried the glue, and then it looked like it was going well, it printed the base of the house then started to work on the walls, and then the model slid around the hot plate again.

What do I have to do to make sure I dont waste time and film to stop it from sliding around after an hour of printing?

I saw this suggestion about making sure you "have a raft" but what is a "raft"?

Can anyone help?

Thanks in advance.

 

Yep found it on the settings , thanks
