Just spent time with the credit unit and discovered that it is not the arms that connect to the coils, but the cog itself seems greasy/slow and doesn't reset fast like the stepper next to it. Does anyone have any tips on cleaning the cog itself? Do you have to unscrew the big nut to remove the cog? Regardless of the tension of the spring, it still seems slow to reset.
Cheers!
