As mentioned, don't connect the stepper motors to the drivers just yet. The drivers will connect to the teensy and stepper motors.For now, don't connect the steppers to the drivers.You will need to assemble the kit by soldering the pins and the capacitor. The ethernet kit connects to the teensy and also connects to the LAN port on your router.Double-check that the connection is cut using a multimeter set to test connectivity. This trace to cut is shown in the last image. We will power the teensy with the bench power supply using the 5V regulator. You must cut the 5V trace on the teensy that connects the USB 5V to the Teensy 5V.The teensy 4.1 microcontroller is where the drivers and ethernet kit connect to.You can also use fixed output rather than the potentiometer. The VO+ pin should output 5V once you adjust the voltage using the potentiometer on the regulator and a voltmeter. Connect the positive and negative terminals of the bench power supply to the IN+ and GND pins respectively.The teensy 4.1 and the logic boards on the TMC2208 drivers use 5V.I spread the electronics across 3 protoboards and mounted them onto a 3D-printed plate. Follow the schematic to build the circuit.
