Each set of electronics for RepRap contains some sort of microcontroller (uC). Each uC is a miniature computer which needs its own software in order to do useful things. The term for the type of software that runs on a microcontroller is 'firmware'. The reason is that ideally, the software doesn't change very often as it is fairly simple and the code should be very robust. Uploading this software to the chip is called 'burning' or 'programming' the microcontroller. | |||||||

Due to the physical and electronic setup of each generation of electronics, new firmware generally must be written for each set. The various firmwares for each are discussed below. | |||||||
