Updating Firmware for the MakerBot Replicator via ReplicatorG

    Every once in a while we come out with a new version of the firmware for the MakerBot Replicator. Uploading the new firmware to your printer will ensure that your printer gets all the latest improvements and operates as smoothly as possible. The most recent firmware released for the MakerBot Replicator is version 7.5. To check what firmware your printer has now, go to the Info and Settings menu on your printer's LCD panel and select Version Number. If you don't see an Info and Setting menu, you can find Version Number under Utilities -- but we can tell you right now that you will need to upgrade if that's the case.

    Disconnect from ReplicatorG

    To upgrade the firmware on your MakerBot Replicator you're going to need to disconnect from ReplicatorG. Once you've clicked Disconnect in RepG, go into ReplicatorG's Machine menu, check Connection (Serial Port) and make a note of which port your MakerBot Replicator was connected to --- you'll need it later.

    Select Your New Firmware

    Now go back to RepG.Go into the Machine menu and choose Upload new firmware…

    The next step is to select the machine you’re upgrading. In the case of your MakerBot Replicator, you’ll want to choose MakerBot Replicator (Mightyboard).

    Now choose the newest version of the firmware. This should be the one at the top:

    Next, choose the correct serial port. This will be the one you noted earlier.

    Finally, you'll see a button labelled "Upload." Do not press it yet.

    Locate the Reset Switch

    The reset switch is on the back of your MakerBot Replicator, just to the right of the USB port. You'll probably also need something to press the button with -- most fingers won't fit.

    Hit the Upload Button, Press the Reset Button, and Wait

    Hit Upload, wait a fraction of a second, and then press the reset button. It will take a little while, but soon you should see a message telling you that your firmware has been updated successfully:

    If your firmware does not update successfully, don't worry -- the timing can be really tricky because it will vary a lot from computer to computer. Try different timings, like pressing the reset switch just before you hit the upload button, or waiting a full second between hitting the upload button and pressing the reset switch. The process of figuring out exactly when to press each button can be frustrating, but you can't harm your printer by getting the timing wrong. And once you have it right, you'll know what works best with your computer and you'll have a head start next time.

    Once you see the "Firmware update succeeded!" message, you're set! Go back to printing with your exciting new firmware.
