Hi David!
And thank you so much! Its not so clear what one should choose, but maybe there isnt many left off us using the older boards...
Grateful for fast reply!
Reprap firmware has protection in place to prevent you from crashing your printer in the form of a homing requirement. You can either home your printer or disable the homing requirement. In order to disable the homing requirement for your printer you can enter the command M564 H0 as stated by @deckingman.
