Z only going up (+)

I have a MPCNC that I built with endstops on the X and Y only. Sending the M119 shows the endstops all working. When I try to home X or home Y, or carve anything, the Z axis just goes up until it can't anymore. I have to press emergency stop to stop it. Any ideas? I've been stuck for 2 days :/

    How do you home z axis without endstop? Which firmware? Does host send commands to go down correctly? Can be as simple as z min always being high so firmware does not go down or direction pin not working or configured wrong or firmware goes only down after homing.
