Calibrating Altair for Optimal Performance


One of the most critical pieces to having a successful 3D print on any printer is making sure that you have a perfectly level surface to print on. This can be a tedious process on other 3D printers, but on the Altair V3 we have made calibrating your bed easy.


Before Starting the Calibration Routine


              Check List:


 Make sure the nozzle clean. The bed is a conductive bed. It works as the hot end and aluminum come together to close a connection electrically. If plastic is on the tip of the extruder, it will cause the calibration to fail(read more about it here).


• Make sure Altair is not connected via USB. During the calibration routine, the computer may try to communicate with the printer. This will cause the calibration to not complete properly.

***Make sure you have removed the removable BuildTak plate***


If the removable bed is in place, it will be damaged by the hot end coming down and touching it. It will keep pushing into the bed causing damage to your Altair stepper motors. This will could end badly.

Selecting the Calibration Routine


Quick Step- Press Dial >Custom > Calibrate


 For a more in depth explanation and understanding of the calibration routine:

1. To begin- Press the dial 



2.The Altair’s Main Menu will appear. Turn the dial down to ‘Custom’. Press the dial to open the Custom Menu.


3. In the Custom Menu turn the dial down to select ‘Calibrate Bed’. Once selected the routine will begin.


What to Expect Once Initiated

For a more in depth explanation of the Calibration routine, and to make sure it is working correctly. Check out the information below. This will show you what is suppose to happen and what to do if it doesn't work.


Calibration Failure

In some rare situations the calibration routine may fail without any warning. The calibration process should go down to the bed 3 or more times and take about 2 minutes before it is completed. If it did not do this, and/or you are having problems with it printing too close or too far away from the bed, then please follow these instructions.

G-Code Commands

In MatterControl's Terminal, or any supported terminal, the gcode to initiate the 'Calibrate Bed' commands are: G32’. Once completed send ‘M500’ to save the calibration.
