X and Y axis are homing fine, Z is moving in the correct direction. Whats not happening is every time I try to home the bed lowers a few mm and stops, so every time I home the bed gets lower. I have triple checked the wires for the IR sensor and they appear correct to the build manual. I have tried both the default Dual firmware and @Alex9779 firmware, both do the same thing. Any ideas why the Z wont home?
