When to Save Calibration Values

When your print is complete it is important to save the calibration values to improve your printer profile on Palette.

You can save the calibration values by using the print feedback at the end of each print will by tapping on the Great or Issues buttons. We recommend using the print feedback for the first 3-5 prints on a printer. This will allow you to improve your prints over time.

By tapping on "Great," this will save the calibration data. This will improve the HM (historical modifier) for your printer profile, and future prints.

The Historical Modifier (HM) is a percentage that tells Palette how much filament to make based on your printer's extrusion. For example, if your HM is 98%, your printer may under-extrude slightly when compared to the GCode, and Palette compensates by adjusting splice length.

You will be able to access ping data by clicking the Statistics button when your print is complete.

Examine the ping data from each completed print, if the ping values are consistent at one percentage or fluctuate by 2-3% use the Great button in the print feedback.

Photo below: example of "great" prints to save calibration data. Here, the print is has colors in mostly the right place, with just a few red stripes on the eyes of the cat model. Pings were consistent, only changing 1-2% throughout the print.

If the ping values fluctuate by more than 5% or there are missed pings in the data use the Issues button in the print feedback.

Missed pings will not have any ping values and will appear as missed on the screen. A missed ping means the ping was so low at this point that it was not registered. Additionally, if you had a calibration print that had a 'No Pings' error, you will find that in your printer profile, HM will be 'None.'

By ignoring the data from missed pings, your HM in your printer profile will not be affected.

Photo below: example of a print with issues where the calibration data should be ignored. Here, >50% of the print has colors in the wrong place which coincided with fluctuating pings throughout the print.

Here are some general tips for settings to adjust to help with print quality and calibration.

• If pings are very high (105%>), you can slightly reduce the extrusion multiplier or flow rate.
• If pings are very low, (>90%), you can slightly increase the extrusion multiplier or flow rate, and extruder/nozzle temperature slightly. You can also try performing a cold pull on the extruder in case there is a clog.

Multicolor prints that have at least 15 pings can be used as test prints to tune the printer profile (this information is available in the print preview after slicing in Canvas). Here are some suggestions as to what to look for in a model after the printing the keychain:

• Print has at least 2 to 4 different colors used throughout the print. This is enough to test color transitioning and should produce enough ping data for Palette to work with for profile tuning.
• Little to no supports will make it easier to complete the print.
• Multimaterial characters or animal models from designers such as cipis, flowalistik or our Thingiverse.
