My K40 arrived today! Thanks to all who contributed toward this!
Awesome! Very excited for you. Hope all arrived in good condition.
I just noticed that yours has a much smaller viewing window than mine. If you have any questions about setting up or upgrading your k40, feel free to ask me, I’ll do my best to help you through the process.

Psu with white connectors, Smoothie Cohesion3D is the right for you.
Spoke with @raykholo about that board, he says they are about 1 month out still. I sent @Todd_Fleming a middleman board and a level shifter, and he has a 4xc smoothieboard that was donated.
I also had one come in last week! Mirrors were aligned already and everything! Even had a LED light installed that I was not expecting. Happy Engraving!
