Thanks guys, I have installed Cura 14.06, and reduced the print speed as well. I will try to print again later.
I was printing at 0.2mm at 70mm/s, so what is the reasonable flow rate for UM1?
@ Dim3nsioneer, yes, it's a 4 legged horse:) I am using the lines support now instead of grid, but I will give Meshmixer support a try as well. Thanks.
