STEP 33 Assembled Mill One Your Mill One is now fully assembled. Don’t plug in your power brick yet, simply connect the USB cable to your computer and continue onto the next steps.
INSTALLING FIRMWARE Open your favourite web browser and navigate to the Resources tab of our website. On the Resources page, under the Software heading, you should notice a link to the Firmware.
Page 38
If you’re using an apple product, your first step will be to download the driver linked on the page. This will ensure that plugging in your Arduino doesn’t cause any issues.
Page 39
Once you run the package in the downloaded folder, the driver will install. You will be prompted to restart your computer, once the restart has completed, you should return to the Firmware page of our website...
Page 40
Back on the Firmware page, you’ll want to click to download the “Grbl 1.1v with default settings for the Sienci Mill One” firmware. You’ll also want to download the latest Arduino IDE onto your computer; select your operating system to download the appropriate package.
Page 41
Open the Arduino IDE once it’s installed Once open, navigate to File-> Open...
Page 42
You should find a folder for the GRBL download in your downloads folder. Navigate through the folders until you find grblUpload.ino, double-click it to open it. This is the code that needs to be uploaded to the Arduino.
Page 43
The last step to prepare for uploading the code is to include the Grbl library. Go to Sketch-> Install Library-> Add .zip Library then navigate back to your downloads folder. Once again, open the Grbl folder then navigate through and double-click on the grbl.zip file.
Page 44
The Arduino IDE should confirm that the Library was added and you will now be able to upload the code to the Arduino. Check in the Tools tab that you’ve selected your board to be the Arduino Uno.
Page 45
Also check that the proper port is selected. Then click Upload on the IDE to upload the code.
Page 46
The IDE should confirm that the code is done uploading. To confirm that the code was implemented correctly, go to Tools then open up the Serial Monitor.
Page 47
firmware has been uploaded correctly. Congratulations! Your Mill One should now be ready to go. In order to start using your machine you should start becoming comfortable with a CAM software as well as find a program which will send the g-code to your machine.
