I think I am the first on the planet to crack this, and this is how I do it! (Well, at least I show you a little) For more information, or to order my S100/S300 Support material, or to change your printer type from Resin to CPX please contact me, Scotty. For expired date material rfid stickers you simply change date in Windows of your printer to 1999 and reboot the projet service. Now you may use expired rfid sticker for materials! DUH! Once you have reset any rfid sticker....you need to use that sticker in different cubby location. This means, swap left and right bottles or move the bottle to new location. Then, machine will detect the rfid and think it is new again. Refill or use wrong material with this rfid sticker you keep resetting. Cheers and F-3d systems!@#$@! and their terrible service and prices and junk machines.
