Project peeling off of raft

Hello,

i am am new to 3d printing. I just purchased a makerbot 5th for my school and now learning to use it. So far so good, but some of our projects are peeling off the raft?

Any suggestions?

thanks!

try using pla, blue tape and no raft.

Hang on 5th gen ? no heated plate. So you are using pla.

So basically blue tape, better calibration and no raft.
Blue tape is blue painters tape: http://www.amazon.com/Scotch-1369894...+painters+tape
I use duck brand but the 3m should be just as good.
Pla sticks to it like hot toffee to skin :-)
And if you've never burnt yourself making toffee - it's an experience to look forward too - not !

I've never needed a raft with pla. And I'm basically using a makerbot 2nd gen copy :-)
Mind you from what I've heard about the 5th gen - I wouldn't swap my cheapo flashforge clone for your spanky expensive machine either :-)
But blue tape and no raft should fix the problem.
