Greetings,

This is the second time I run into a cylindrical part (with a relatively thin wall thickness) that ends up being deformed in the layers closest to the bed. Reference attached photos. This is using HatchBox PLA on a Prusa 12" i3v with Slic3r 1.2.9.

I suspect this has to do with uneven cooling between layers because the same cylinder printed on top of a thick base of plastic does not deform like this.

Has anybody else run into this issue and found a solution? I suppose I could try printing the cylinder with a raft to see if it helps. I find this printer's/software's rafts are a pain to remove though.

Thanks for any comments or suggestions provided.

Chachin..

PS: Merry Christmas!
