Estimated Repair Time:

Tools you will need:
Screwdriver
T6 Torx
T10 Torx
T20 Torx
1 small 4" zip tie
Parts you have received from Voltera:
Control board PCB
Save your calibration presets
Some of our machine calibration presets are stored onboard the control board. If we replace the control board we will need to manually write the calibration presets to the new control board.
Replace the control board
Swap the compute module (Optional)
If the new control board you received does not have a compute module mounted to it we will need to swap it from the current control board.
If your new control board has a compute module installed you can skip this step!
With the control board off, you can remove the two screws holding the compute module in place, with a T6 Torx.

Release the two locking tabs on the module and it will swing up towards you about 10°. It can now be removed by sliding it down and out.


Install the compute module onto the new control board by reversing the previous steps. Slide the compute module into the slot on the control board at a 10° angle and push down to engage the two locking tabs.

Secure the compute module in place with the two screws and a T6 Torx.
Set your calibration presets
Save the calibration values
Type the command M520
into the console to output the current calibration values. Take a screenshot of the command line output and send it to our support team by email ([email protected]) or chat along with the screenshot of your previous calibration values.

Our support team will now give you a list of commands to copy and paste into the console that will save your previous calibration values to the new control board.
Repair Complete!
Congratulations, you have successfully replaced NOVAs control board!
Please reach back out to our support team through email ([email protected]) or the chat to let them know everything went well. We will arrange a shipping label to return the old parts back to us for further testing.
