Neptune 4 Max Motherboard upgrade

[Jasper van Roest]

Hello! this is my first post here so I hope I am in the right thread.I am looking to upgrade/extend my Neptune 4 max motherboard because I would like to make it a double extruder printer. But I don't see anyone else do this on the Internet. BigtreeTech has some great 8-stepper motor board that support klipper and touchscreen and all the other stuff for the Neptune 4 Max. But it isn't clarified as compatible with the Neptune 4 Max. So before I buy it I just wanted to ask here if anyone knows if it will work. I was looking to buy this one: https://www.3djake.nl/bigtreetech/manta-m8p-v20#js-faq BigTreeTech Manta M8P V2.0Thank you!
