Agreed -increase steps/per on dip switches by 25%
Re: 4th axis overshooting
on, off, on, on gives 8 microsteps. Your last version off, on, on, off gives 10 microsteps and (from memory) is correct. Switch 4 is also ok but 1 to 3 all set to on will deliver only 2A. The required current depends on which 4th axis you have. If you do not have the superspacer version this is probably ok.
