this is the stock firmware for a prusa I4 with eprom enabled
thingiverse
I contacted the manufacturer to obtain the factory firmware, which includes a custom temperature table, and it was worth the effort as it ensures that the temperature is spot on. To allow for future modifications without having to reflash the device, I've enabled the EPROM in this updated firmware. Prusa i4 owners will appreciate this modification, and I've included a bonus hand model - you can find the original design at Thingiverse: http://www.thingiverse.com/thing:31331.
