hey hey .. so my old summasignpro D610 24" with led strip just decided it didn't want to recognize the pinch roller wheels have been lowered. Not sure if it's a sensor issue below the deck or the little blue switch that's attached to the lowering arm. But anyway, i love my summa! I've had it for like 30 years and it's been good to me and my God the accuracy and ability to handle anything I've thrown at it is remarkable, so i want to fix it if i can. So I'm looking for a donate machine for parts or functional if anyone has one. I'll pay for the postage to get it to me here on the east coast. thanks
