Was exactly what i needed to complete my filament encoder for my voron 3d printer. The unit matched my design perfectly and worked flawlessly. I did need to swap the vcc and sig wires on the connector to match the pinout of my octopus pro main board, but otherwise these worked great and i have all i need to build more. Thank you co much!
