1.Supported hot bed power increased to 144W,The power of the hot bed connected to the motherboard must be less than or equal to 144W (ie, the thermal bed resistance is greater than 1Ω), if a high-power hot bed is used, the external hot-bed power expansion board must be connected.<br><br><b>SKR motherboard power:</b><br> After the SKR main board is powered on, the red light of the D4 in the lower left corner will light up, indicating that the power supply is normal; the 5V SEL in the middle of the board is the power selection end;<br> 1)When using USB to power the motherboard, connect the +5V and USB pins with a shorting cap.<br> 2)When using 12V-24V power supply, connect the +5V and INT pins with the shorting cap;<br> <b>NOTE</b>:It can be connected to [12V-24V power supply] and [USB] at the same time. The printing process must use the shorting cap to connect the +5V and INT pins.<br><br> <b>SKR motherboard communicates with computer:</b><br> The SKR motherboard communicates with the computer through the [USB] interface. After the driver is installed, the motherboard is inserted into the computer to recognize the port for data transmission. It is easy to see that the computer does not recognize the USB port without installing the driver.<br> 1.smoothieware-usb-driver-v1.1 driver installation (Windows systems only)<br> The driver can be obtained from our open source network;(Contact us to get the link)<br> <b>Note:</b>When using smoothieware open source firmware, since only Windows system drivers, the SKR board at this time can only be recognized by the Windows system port! ! !<br> 2.If you are using Marlin2.0 firmware, follow the tutorial to install;(Contact us to get the link)<br><br> <b>NOTE:</b>If you need more methods and materials, as well as how to change the firmware and get the firmware, please contact us.
