3 Flashing Firmware

After closing out of the Machine Settings window, you will be brought back to the Manage Printers window.

Ensure that the correct printer/tool head is selected and highlighted in blue.

Close this window and go back to the Cura main screen before clicking on the MONITOR tab at the top of the software.

Once connected, locate the Firmware Update button under Connect, Disconnect, and Console, and click that to open the firmware update window.

You can follow the on screen warnings to save your current E-step and offset values if you are going to install your previous tool head again in the future.
If you are installing one of our universal tool heads, you do not need to restore the E-steps from your old tool head.

The new firmware will install the correct E-step value for your new tool head.

Select Update Firmware, or Upload custom Firmware if choosing a firmware file manually.

Once started, a progress bar will show the status of the firmware installation and will indicate when the firmware update has completed. Your printer will restart once the firmware update has finished.

Depending on your printer and the firmware version used, you will still need to select the correct tool head via your printers LCD.

Navigate to the first menu screen on your printers LCD and select the Tool Heads menu.

Scroll down until you find the correct tool head that corresponds with the tool head installed on your printer and select it.
