This is where my help ends because I am still new to learning this setup and spent most of my time making this guide. Most of the experienced people who have used the CoPrint products are in their official Discord.
They gave me great tips and helped out a lot to see success in me installing this kit. Make sure to keep issues in the scope of the CoPrint product when discussing issues.
This guide is open for edits, if anyone has any recommendations or adjustments I should make to this guide, please contact me on Reddit.
