Hi!
I just got the coin mech from Ultimarc. The unit is great fun, but
it will sometimes miss a coin or 10 in a row.
All of a sudden it will start not accepting the coins, just giving them back. What should I do to make it less 'picky'? There is
a potmeter that says sensitivity, and a switch that says coin
speed. What are these for?
Does anyone know what it looks for in a coin? is it just the size or what?
Thanks!
Nicholas
