Hi Anders,
Obviously your drives microstepping is set to 1/8 which is just fine.
You are very unlikely to achieve any higher resolution or performance if you change microstepping to 1/16 so it would be better to leave it as it is.
I assume your switches are normally closed circuit (n.c.) connected in series. With everything switched off, use a multimeter (on continuity) at the breakout board to test your switch wires which should show closed circuit - operating any switch should show open circuit. If this is not the case then you may have made a mistake in your wiring of the extended switch.
Tweakie.
