MakerBot Replicator 1 Firmware Upgrade

Updating the MakerBot Replicator 1 firmware requires a bit of patient to get right. It requires exact resetting and uploading timing for the process to start.

MakerWare

One way, and the easiest, is to update the firmware via MakerWare (as of writing 3.5.0.39). Select Device and Update Firwmare, and follow the instructions.

I couldn't get the timing right, so I decided to reverse the uploading process and do the update manual using avrdude. See the following section.

Manual avrdude

Getting the timing right is quite finicy and time consiming. Getting down to the command-line and perform the update manually can save you a bit of time and head banging.

Should work equally well on Windows and OS X, Windows shown below.

1. Open a command-line window, Start, type cmd and enter
2. Change directory to MakerWare and avrdude, cd "\Program Files\MakerBot\MakerWare"
3. Power on the Replicator and find the COM-port used, Start, type Device Manage and enter, under Ports find the port
4. Get the firmware binary by either
   1. Starting the MakerWave upload process once and failing (to get the firmware downloaded), then going to \Windows\Temp and searching for *.hex
   2. Download the firmware version from the links below
5. Copy the firmware (*.hex) to "\Program Files\MakerBot\MakerWare"
6. Execute the upload command, avrdude.exe -Cavrdude.conf -pm1280 -b57600 -cstk500v1 -P \\.\COM6 -Uflash:w:mighty_one_v7.5.0.hex:i -v -v
   1. Where you change COM6 to your COM-port and firmware file name to your desired one
7. Move the keyboard and Replicator to arms reach
8. Simultaneously press the Reset button on the back of the Replicator and the enter key on the computer to start the process
   1. Vary the time between until you see avrdude detecting and uploading the new firmware, this can take 1 to 30 tries but it will work eventually
