Getting Windows to recognize the controller
This appendix will cover two basic controller designs that are common for RepRap-based printers:
- Arduino Mega 2560 is based on the ATmega2560 microchip (the older ATmega 1280 may also be used on older machines)
- Sanguinololu is based on the ATMEGA644P microchip
If this is the first time you have tried to upload some firmware, you'll discover that there is a need to install the drivers that are specific to the controller.
For the Arduino Mega, you'll need to follow these steps:
- Plug the board in using the USB connection. Windows will attempt to find a device driver for the board and will most likely fail.
- Open Device Manager in your system. Locate the yellow exclamation mark labeled Arduino Mega 2560 under ...
