@BobNevalainen You’ll enjoy your new toy, just make sure to prowl these forums - most problems you’ll encounter will have most likely been found & fixed by others already.
While you wait, I’d strongly suggest you begin looking through the assembly videos and instructions. They’re pretty good, but it’s worth going through them a couple of times. I’d also suggest looking through the forums for the process of adjusting stepper motor current/voltage. It’s pretty standard that you’ll need to do this before things will work properly.
Wasteboards - I live in Australia and also wasn’t prepared to pay hundreds of $$ for a bit of MDF - have a look here for an alternative solution to the wasteboards that I’m using. It’s not as nice looking as the original design, but it’s cheaper and pretty effective. I’m also happy to cut into it without fear of damaging the beautifully silkscreened and drilled “wasteboard”.
