Curt, I thought that I had also been obsessively careful as I marked it with a "sharpy" to know where the flat was but I must have been just a bit off and with the scope load rocking it back and forth, the screw gradually worked itself loose so that it went from perfect (No backlash or delay in reversing the motors) to a 7-8 sec delay in reversing the motors. Just something to be aware of.
