Yeah i know, but they were very persuasive and it was a cohesive effort across the whole team.

I tried it twice - so they definitely got me :-)

My biggest problem with blue tape and pla is getting LESS stick !
Think I might be getting there. I've de-calibrated slightly and lowered the pla temp to the point where any lower and it won't stick at all.


For designing I love openscad. I can't draw, never could, never will.
But I do have very good visualisation and 3d perception. So I know what i want and where I want it and openscad lets me just tell it what I want and where to put it.

It can look a little disconcerting at first. But once you realise the syntax is the same no matter what - you just get used to sticking in the brackets and the rest is basic arithmetic.

You can make something simple like an open topped box with three lines of basic code. Takes about 30 seconds. try that in a gui cad package.

The more you use it, the easier it is to do complicated things. Some of the most complex models on thingiverse are done in openscad.
Openscad still escapes me lol sorry, even thou by nature I am an old school programmer, when it comes to modelling I find it very hard to go from a visual design perspective to a mathematical one. After 5 years of blender, I know all my metrics, I know which machines and what software screws up those metrics (like makerware reduces ALL models by 0.8% scale when printing. keep that in mind) so I sort have been sticking with Blender and RepG/makerware/pronterface

For PLA not to stick, that's wierd, how hot is your bed? i'd even try turning it off completely.
