i am looking for a schematic of the cohesion 3d controller
There is not one publicly-available. What are you looking to do?
just want to know what all the connections are for…i’am upgrading my system
We have not yet released a pinout diagram as we prefer to walk people through whatever they want to do and are happy to answer those questions.
