was having problems with the mystery wheel where either the wheel would only spin a little or not at all and i would get 1111111 across the display, i put in a new opto and reheated the solder on the stepper motor board. now the wheel spins great but the correct amount doesnt show up where his finger is, the amount that shows up on the display is always 1 or 2 spots below his finger. did i not do something incorrectly? if it helps to figure out anything the new opto wasnt tall enough so i put washers under the post mounts to move the stepper motor board up closer to the wheel so it would trigger the opto, before the washers it wouldnt trip.
New! Dark mode!
