Restoring your CNC3D Commander IP address (and other settings) after update Including USB recovery on V1 Nighthawk cards
What we’re seeing a lot right now is that after updating Commander, the IP address field at the top gets cleared. When that happens, the quickest fix is usually just re-entering your correct IP address and hitting connect. That alone resolves most cases straight away.
There are two common paths to fix this depending on your setup:
Option 1: Re-enter your IP address (fastest solution)
Open Commander
Enter your IP address back into the connection field
Click connect
If you’re unsure of your IP range:
Press Start → type CMD → press Enter
Type ipconfig and press Enter
Look for your “Default Gateway”
The first three numbers will match your network
Your Nighthawk is typically something like xxx.xxx.xxx.155
So this means...
If your Default Gateway starts with: 192.168.1.x
Then your IP of your Nighthawk is likely 192.168.1.155
This is usually the simplest and quickest way to get back up and running.
If this does not resolve the issue follow on...
Part 2: Reinstall the V1 driver (for USB users with CH340 issue) and Restore User settings manually
There is a known issue affecting some older, out-of-warranty Nighthawk units using the CH340 chip. Reinstalling the V1 driver resolves the majority of these cases.
Steps:
Download the CNC3D driver bundle that includes the Nighthawk V1 driver from:
https://libraries.sharpsoft.com.au/drivers/cnc3d-usb-drivers.zip
Right-click the ZIP file → Properties → tick “Unblock”
Extract all files (do not run from inside the ZIP)
Run the installer from the extracted folder (SETUP.exe) - See the "HOW TO INSTALL" image file
Optional: Restore previous settings
If your settings were reset during the update:
Press Start → type Run → open it
Enter %localappdata%
Copy everything from inside the CNC3D folder
Paste it all into the CNC3D PTY LTD folder
That should restore your previous configuration.
Issues still persist / I'd like CNC3D to handle this
If you’d rather not go through the steps yourself or you still have an issue after trying these fixes, we can log in remotely and sort it out for you:
Priority support is complimentary for machines or controllers inside of warranty. As this issue only seems to affect V1 Nighthawks exclusively (which stopped production in February 2024), it is outside of the warranty period. February 2024 is when the last batch of V1 Nighthawk cards were made, while completely arbitrary to note this fact, some users have asked why they may have received a V1 card after this date. That is because we produced the last batch of V1 Nighthawk main cards in Feb 2024. We then had the entire batch on hand to go through until all V1 cards were distributed before launching the V2 Nighthawk cards.
You can purchase priority support if you would like us to remote in and try and resolve it, it can be easily purchased in blocks here:

This article lays out a detailed plan here for you to follow. This plan will most likely (> 96% chance) solve your issue.
If you follow the IP method first, there’s a very strong chance you’ll be back up and running within a minute or two. If not, the driver reinstall will take care of the rest.
