I have same problem. It causing warping of the raft. I thing that solution is adding an option of 2 perimeters first raft layer, or printing skirt and raft both. Unfortunetly i didn't found way to set it in Cura yet. Maybe new feature for 2.1.X? Little suggestion for Team Ultimaker.
Hi, i configured my custom printer as a modyfication of ultimaker original. I'm trying to add custom materials to list (by adding and editting *.cfg files in materials>>general folder). Materials are working fine, but after restarting the Cura it starts with printer configuration (add) wizzard. I tried back up *.cfg files, but it doesn't help. Do you have any solution?
