When to update or Re-install Firmware

If you are having problems with printing too high to too close to the bed, or functions are not working at all, you may need to re-install your firmware. Attached at the bottom are the files you will need for this walk-through. Please follow the directions exactly.

Check back for future updates. New updates will have a more recent date in title of this article.

Choosing the Correct Printer Firmware

The serial number on the inside top of your Altair indicates the version and corresponds to the proper Firmware and Configuration File to be used:

V3.0 Altair: PSXXXXV3.0XXXX - Filament driver in the base of the printer 

V3.1 Altair: PSXXXXV3.1XXXX - Filament driver located at the top of the printer

V3.2 Altair: PSXXXXV3.2XXXX - Filament driver located at the top of the printer 

V3.C Altair Carbon:  PSXXXXV3.CXXXX - Carbon Fiber Altair with flex plate for easy print removal

Installing Altair Firmware Update

To get started make sure that your printer is plugged in and not printing! Then follow these instructions to update your Altair Printer. 


 1. Plug the usb cord from the Altair into your computer


 2. If AutoPlay is on it will ask you to open Altair’s folder to view files.


 3. Open the folder.

4. These are the files that come preloaded on your Altair


5. If you have had your printer for a while you may have more. 



 6. To remove the old firmware delete the Config, Config-override, and Firmware.CUR files.



7.  Go to the .zip file you downloaded for your printer’s version, unzip the file, then copy & paste these files directly into your Altair Folder. (7zip is a free zip file opener if you don't have one - 7zip link)

 A. Unzip Files


 B. Open extracted folder





C. Copy everything in folder




8. Once you paste the files into the Altair  a window will appear reading The destination has files with the same names Select- 'Replace the files in the destination'.

9. Note that the “firmware” file is a “.bin” file. This means it has not been flashed/installed yet.




10. Eject your Altair V3 printer and turn it off.







11. Turn the Altair V3 printer back on and plug the USB back into your computer.


12. When prompted by AutoPlay, open the folder again.


13.  Note that the “FIRMWARE.BIN” file that you pasted into the folder has been changed to “FIRMWARE.CUR”.


This means the new firmware flashed and installed correctly!


 14.  After re-installing or updating the Firmware you will need to re-run the Calibrate Bed routine.


15.  It is recommended that you also run the "Hotend PID" routine as well as the "Bed PID" routine from the custom menu after re-installing the firmware in order to optimize the Altair's heat-up routine.

Congratulations! You have just successfully updated the firmware of your Altair 3D Printer.
