INTRODUCTION
If you're not printing with a Palette, please skip this step. In the following steps Palette 2 will
automatically calibrate with your printer. Palette needs to produce the exact required length for each
filament so that splices reach your nozzle at the correct time. However, 3D printers aren't perfectly
accurate. For example, your print file may contain 10m of filament extrusion instructions, but your
printer might only use 9.7m of filament. These small errors add up over a print, slowly throwing off
the alignment of splices.
Calibration gives Palette a baseline for the amount of error in your printer's filament consumption so
that filament production is adjusted accordingly. This is especially crucial at the start of a print,
before Palette's live feedback systems kick in.
Before you begin the calibration print, please make sure that you have already completed the
following:
Update Palette 2 firmware. Always ensure that you're using the most recent version of our firmware
as we continuously improve features.
Set up your Palette 2, 3D printer, and Filament holder. When you turn on Palette 2 for the first time it
will guide you through the initial setup. Make sure that the following have been completed:
- Palette is positioned close to your printer
- Palette is secure on its stand
- The small Teflon tube (50cm) is fastened into Palette 2
- Power supply is firmly connected to Palette and the wall outlet
- Filament is untangled and spools are positioned to feed filament easily

Step 1 — Enter the Outgoing Tube Length on Palette
On Palette screen navigate to Next > Other and then select 'Custom' and then using the arrows,
change the amount to the length to 102cm. If you don’t see 'Next' select Settings > Preferences >
Outgoing Tube Length select 'Custom' and then using the arrows, increase the amount to the
length indicated in the chart above.

Note: Tube length is printer type specific. The tube lengths in the chart above should be set in
Palette when you are using the corresponding UM printer. If you switch your Palette to another
printer, ensure that you set the tube length back to the appropriate tube length that you have set
up for that printer.

Step 2 — Download Calibration Print and Slice
Download the dual-color keychain: https://www.thingiverse.com/thing:330157...

Slice the keychain model in CANVAS. After slicing in CANVAS is complete you will have two files.
The first is a SEEM file that will have the extension MAF (Mosaic Accessory File). You'll also
receive a modified Gcode file. Transfer the MAF to Palette 2's SD card manually. Transfer the
modified Gcode file to your printer.

Step 3 — Remove Palette's outgoing tube
Please disconnect the Palette 2
outgoing tube from Palette 2 by
firmly pulling it out, this is a push fit
connection so you will need to use a
bit of force to remove it. Ensure that
there is no filament in the path from
this tube to the hotend. If there is,
please remove the filament so that
the path is clear.

Step 4 — Starting the Print on Palette
Turn on Palette 2 and select 'Start Print'.

On the top left corner of the screen, you can select to load a file from Palette's SD card (MAF file)
or via CANVAS Hub (MCF).

Palette 2 will recognize that this first time you have used it with this printer and will let you know
before you start the print. Please go ahead and tap 'Next'.

Step 5 — Load inputs and start splicing with Palette
Follow the onscreen instructions to clear the outgoing tube which you would have already
completed in step 3. Load filament into the inputs, making sure not to clear filament for any inputs
as clear filament is used later in the calibration process. Allow Palette 2 to output filament with the
outgoing tube disconnected.

Step 6 — Heat printer and insert filament into extruder
After 2-3 minutes the screen will prompt you to feed filament into your printer's extruder gear.
Select 'Next' on the following two screens until you see the screen below that says 'Slowly extrude
filament…'.

On the Ultimaker screen select Maintenance > Advanced > Heat up Nozzle > Scroll to 210C. Wait
until the temperature reaches 210C. Caution: the nozzle will be very hot through the next few
steps.

Step 7 — Remove bowden tube and pre-load clear filament
Remove the bowden tube from the print head by removing the lock clip.

Find 20-30cm of clear or white PLA. Manually load into the print core from the top of the print head
until you have purged any remaining material which was in the print head. You should only see
clear filament coming from the nozzle when it has been fully purged. Pull the filament you just
inserted back out before proceeding to the next step.

Press the bowden tube back into the print head and replace the lock clip. It is critical to ensure that
the bowden tube has been inserted as deep as it can go in order to effectively restrain the Teflon
tube in the print core.

New line.

Step 8 — Loading filament into the Ultimaker feeder
On the Ultimaker screen return to the main menu and then select Material > Change > PLA. The
printer will attempt to unload and will ask you to remove material. Select 'Ready' and then 'PLA'.

Feed the Palette filament into the Palette outgoing tube connected to the Ultimaker extruder. Push
the filament in until you feel that it's gripped by the drive gear of the printer. Simply gripping the
filament with two fingers is a quick way to check if it is being moved by the extruder and has
engaged.

Please ensure you hold the outgoing Teflon tube and that you are prepared to connect it to the
Palette 2 without having it tangle as the Ultimaker pulls filament in. Press 'Ready' on the Ultimaker
screen and it will start to load, once the printer has finished loading process, press 'Ready' again
immediately to stop loading.

At this point the filament will have been moved to the entry of your Ultimaker hotend. In the next
steps we will manually move filament to the tip of your nozzle. On the Ultimaker screen select
Maintenance > Advanced > Move Material.

Continue rotating the dial slowly until you see the new color form the filament you are loading
appear. For example, if the filament you are loading is blue and you had purged the nozzle
previously with clear filament then stop loading as soon as you see a slight amount of blue filament
come through the nozzle.

Press 'Next' and then 'Save' on the Palette screen to lock in this loading offset value.

Step 9 — Start Print
Start the print on the Ultimaker screen by navigating to Print > Select the calibration print. If you
get a message 'This print job is not suitable for this printer…', select 'Ignore'. Please note the
printer may take 5-6 minutes to initialize. It will start automatically after this.
