Raft bond too strong
When printing with rafts I'm having trouble separating the piece.
The raft tears pieces out of the print of or leaves parts of itself permanently attached as though it is a part of the print.
Are there any settings to reduce the strength of the bond? I'm using Makerware and CTC 3D and PLA.

Some slicers allow you to specify the raft to model distance. I have no idea if Makerware does as I have never used it.

What bed surface and adhesive are you using ??
If you have a Glass plate on bed and are using Aqua-net spray, then there should be No problem.
If not, that's what you Need !
Note: Let bed completely Cool before removing object, will help with large area objects

Oops, Sorry !
Read it Too fast, since I had a print going .
We have never had that problem with Makerware version-2.4 but maybe later versions create the Raft differently ?
I had other problems with version 3.7 when tried it. so went back to 2.4 .

Hi! I have never used Makerware as a slicer. I used Slic3r software for slicing my 3d models. However, I found a link about configuring the raft settings for Makerware, this might come in handy for you.

Thanks Bobby that's very useful, I was trying Slic3r yesterday and getting some acceptable results without needing rafts so this may be the better option.
@Eagleseven I'm still using the blue tape and original bed that the machine came with, glass bed seems to be recommended in all my trawling of forums etc. so will probably get one.

the raft of makerware 2.4 is pretty easy to remove. Althouhg I did find on longer porints with abs - becasue the bed was so hot the raft and print fused into one piece.
Yet another reason for pla :-) No rafts necessary.
