<blockquote>
"now, with regards to printing ... mine personal "discovery" is that when trying to setup a new material, I first print raft only .. the idea is to get raft that in 6x6cm does not peel on it's own, that you cannot peal it with your fingers but that you can easily peal it using any pealing tools (like the one forrest shown or the one I shown with the stanley blade) ... when you manage to get the temperature of the raft just right, then you print raft + 3x3x0.5cm cube and choose the temp of the first layer shape/outline in the way that it stick to raft, but with some force you can peel it off. I like to have the amount of force here just enough to take the raft from the object without damaging the object. ... then you need to figure out the temperature for the rest of the object .. this is "feeling" ... after some time you can tell by looking at it that it is too hot or too cold ... also, different objects, different structure, different size ... there's not "one size fill all" here ... there is cool plugin that can help here but let's save that for the advanced course "</blockquote>
