To install the corner brackets that will replace the metal corners of the BCN3D Smart Cabinet, follow these steps:   **1.** Turn off and unplug your printer from the BCN3D Smart Cabinet. | ![epsilon-turn-off-2](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Epsilon/Apagar%20impresora/epsilon-turn-off-2.png?width=459&name=epsilon-turn-off-2.png) | ![epsilon-turn-off-1](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Epsilon/Apagar%20impresora/epsilon-turn-off-1.png?width=459&name=epsilon-turn-off-1.png) | | --- | --- | **2.** Move your printer forward from the Smart Cabinet a couple of millimeters to gain access to the metal corners. ![sc-metal-corners-1](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/sc-metal-corners%20Cropped%20(1).png?width=688&name=sc-metal-corners%20Cropped%20(1).png) | **3.** Using the hex wrench, remove the nuts that hold the metal corners. | ![nut-icon](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Tools/nut-icon.png?width=36&name=nut-icon.png)**x4 M4** | | --- | --- |   **4.** Position the printed corners on the bolts and screw the nuts loosely.   **5.** Adjust the position of the support corners to fit the width of the printer and fully tighten the nuts.   **6.** Push the printer until it is in perfect contact with the support corners. -
