Backlash...sorry not at lappy atm but ~10 steps is about right...although, this is a guess I suppose I should actually use a dial test meter and measure this.....Meh...no!
Edit:
Should also say that +5V is routed out unused pins on the DB9 connector so you can hook up a temp sensor near the motor, if you want. Of course the temp signal is also routed thu the DB9 as well. But these are unused pins on the ML system so this will not interfere.

thanks for the info Brendan - have upped the pulses to 50ms.
if of any interest, the step size on this Moonlite Newtonian focuser is 4.1 microns, which is perfect for the 40 micron focal zone in my f4 scope. At 6 steps per focus unit (ie 25 microns), the SGpro software generates very nice v curves and focuses as well as I can.
