+# OctoKlipper: Auto-reconnect printer after power-on
+[Source](https://arnav.jain.se/2020/auto-restart-klipper-when-ender3-connected-to-pi/) by Arnav Jain.
+
+Start off by accessing Octopi using ssh. \
+Then  create the `98-klipper.rules` file in the /etc/udev/rules.d/ folder:
+```
+ssh octoprint
+sudo touch /etc/udev/rules.d/98-klipper.rules
+```
+
+Retreive `idVendor` and `idProduct` for the Klipper MCU:
+1. Retrieve Klipper MCU ID
+```
+lusb
+```
+![Find Klipper MCU ID](images/aswx2-find-mcu-id.png)
+
+2. Retrieve `idVendor` and `idProduct` using the Klipper MCU ID
+```
+lsusb -v -d 1d50:614e | grep id
+```
+![idVendor and idProduct](images/aswx2-klipper-mcu-idvendor-idproduct.png)
+
+Then add the following text into the `98-klipper.rules` file just created:
+
+1. Edit the `98-klipper.rules` file
+```
+sudo nano /etc/udev/rules.d/98-klipper.rules
+```
+
+2. Add text (remove the `0x` at the begining of the IDs)
+```
+## rule to restart klipper when the printer is connected via usb
+SUBSYSTEM=="usb", ATTRS{idVendor}=="1d50", ATTRS{idProduct}=="614e", ACTION=="add", RUN+="/usr/bin/sudo -u pi /bin/sh -c '/bin/echo RESTART > /tmp/printer'"
+```
+
+Finally, re-load the udev rules:
+```
+sudo udevadm control --reload-rules
+```
