Bottango Preview Version
Because the software for the Captain Cogbrow Pro Upgrade kit is still finalizing, you’ll need to use a preview version of Bottango to unlock the new functionality. When it is complete, it will be the version available on the Bottango home screen for everyone. Until then, keep an eye on this page for the latest version and updates.
You need to use the preview version of Bottango linked here to use the pro upgrade kit functionality
If you have a pro version of Bottango with the pro parts in the box (as opposed to a seperate upgrade kit) you’ll need to use the version of Bottango here to get the interactive assembly steps of your pro Captain Cogbrow kit.
Be 100% sure to BACKUP any project files you made in a previous version of Bottango before opening it in a preview version posted here. Bugs can happen, and it’s important to keep a safe backup of your work while the software finalizes.

Version 0.7.1p6c is the latest version, released on 10/31/25.
Though your hardware is in your hands, there’s still work to be done to get the software side of things in perfect working order. In each section of functionality, there will be a “meter” showing the status of each set development, from “unreleased” to “done.”
Your patience as I work through bugs, as well as bug reports and feedback, are all greatly appreciated!
