Hi Dirk Jan,

Can you tell us some more about your set-up? What board are you using? Drivers? Are you SURE you are using 5 steps per mm? Usually a NEMA 17 (I'm assuming you are using them) takes 200 steps per revolution. An 8mm pitch leadscrew means that one revolution creates 8mm of travel. So, 1mm travel would require 200/8 steps, or 25 steps per 1mm.
