What if you ran the updates sequentially from ver2.0, i know Tormach state that you don't need to but my logical thinking is if they up dated the code and firmware as they progressed then possibly by going straight to ver 2.10 could miss out some important upgrades. Has Tormach released a newer USB master key since ver 2.0. Since ver 2.6 ? they have changed their control boards to include a programmable logic device and not use the mesa version. That looks to me where the changes in firmware have taken place but that then begs the question if you had an older 1100 3 machine do the update scan for the mesa card/version and load the appropriate upgrade to the firmware so if you has say the plasma table with the newer control board the update can figure out the difference and load the option that closer matches the machine.
