so this is an interview question for a programmer:

swap two variables without a temporary variable

well

a=3
b=5

a=a+b
8=3+5

b=a-b
3=8-5

a=a-b
5=8-3

a=5
b=3

first real print test

-hardware works on long runs... check
-software is stable for now... check
this looks actually ok to me. now some better coding and the results are actually usable (just 6 layers here) :D

3D Printer over USB

finally I had time to rewrite my software for the stepper motor controller card, so now I can use it over my USB IO board/expansion board. Now all that is left to do, is the additional stepper controller (my circuit), but I guess I forgot to buy some parts for it, so it will take a while... and then yeah, build the damn mechanics!
