nip 4 not finding home. usually I roll them over by hand...and itll run... Then, yesterday I took the sensors off and cleaned them. and it ran all day today restarting now. that also can fix it. its a rare thing, but now its stopped the party. what could cause this? motor going?
EDIT: sensor held in by tab, that tab i think has been broke from the outset. could see it crooked back there. HUGE pain to get back in there, since Im dealing with "tennis elbow" tendonitis. little electrical tape, and 'voila. we are in business. will update the threa if anything else comes of it.
It could also be a loose timing disc on the motor. Also a pain to get to to tighten down as well as ensure correct positioning.
