I currently have a 5 year old Coburn Exelon 8000 edger. For the most part I'm pleased with this bread and butter edger. I'm not happy with it suddenly starting to cut cr39 and poly lenses too small regardless of frame type. We didn't change any settings in the machine. Is it too much to expect Coburn to explain why this happened? This leads me to ask how often does this happen with a Satinelli?
Thank you in advance,
Kenneth
