Im strugeling to get my first print right..It's to big..
Im drawing up a cube with a cuple of holes in sketchup, export it to .STL and opens it in pronterface.
All looks fine, in the pronterface panel the messures look right 50x50x15 mm
I start print and it's all goes wrong.

Could be your stepper motor settings in firmware. Check the steps per revolution and also whether you stepper drivers support 8x microstepping or 16x. This is the most common reason why you get scaling problems.

Have checked some of this, I got the 200 steps /rew stepper 1.8 degr.
The straps on the board is 'all inn' wich if I read the table correct is 1/16, and the fw is standard sprinter

Does this say anything, As a newbie I'm not to keen on doing things in the firmware.. guess things dont work at all
if I do this..

Can some of this info be of any assistance in finding the problem ??

You have to set up the firmware to match the hardware, it generally, unless provided by a kit manufacturer doesn't just work.
