I just found a project on github, that uses an arduino to read and write the EEPROM of Stratasys Cartidges. Theres a UI to set whatever values you want to the EEPROM: https://github.com/slaytonrnd/CartridgeWriter

They're about three bucks each in singles.
Why not buy a couple, swap it out and see what happens?
