Print quality issues with overhang

[mightybhwk]

Hi all,

I am starting to print out the pieces to the mostly printed CNC machine on Thingiverse and i am having some issues.

Pictured below is Corner_Block2 and as you can hopefully see the overhang looks terrible. I've tried adjusting the temp up and down and slowing the speed. Nothing seemed to help. It looks like this on any inclining section.

I've had this issue on other pieces using different filament so I don't think it's that. I am using Makerware not sure if other software would be better. I could try supports but I don't think it should be needed.

Any suggestions?

Here's what I used:

Times printed: 4
Printer: FFCP
Filament: Sainsmart PLA
Shells: 3
Infill: 40%
Software: Makerware
Speed: Default in makerware (The one pictured was at 90% in sailfish firmware)
Temp: 220 down to 205.
Active cooling: on 3 out of the 4.
Orientation: Default when preparing it in makerware. (Thought maybe turning it may help)
Resolution: .25

Thanks,

Randy
