Regarding Mainboard:

Description:
The SKR main board, especially suitable for small and medium-sized printers.

Features:
1) ARM-class Cortex- series LPC1768 master with 32-bit main frequency 100M Can be greatly improved;
2) Equipped with highly modular open source Smoothieware, convenient for users DIY and secondary development, do not worry about the inability to master the core of worries;
3) Using powerful development tools, Keil MDK integrated development environment: online debugging, more helpful for product development and performance optimization, using language development, low development threshold.
4) board wiring is rigorous and beautiful, and specializing in heat dissipation optimization.
5) Using a dedicated to 12-24V input;
6) Acceptable 24V input, the hotbed current can be reduced to 1/4 under the same , effectively solving the heating problem of the hotbed MOS tube;
7) Display: 2.8-inch, 3.5-inch touch screen, LCD12864 screen;
8) The system supports Chinese simplified Chinese, English and languages, which can be switched by itself;
9) Upgrade the by SD card, which is easy and convenient to operate;
10) Use the configuration file to set the driving current mode, avoid manual adjustment of the current to cause the drive, convenient, safe and reliable;
11) High-performance MOSFET tube for better heat dissipation.
12) functions: Non-trace resumption after off, run out filament, and auto shut down.

Using Method:

1. After the SKR motherboard is powered on, the red light D4 in the lower left corner will light up, indicating that the supply is normal; The middle of the board 5V SEL is the supply selection end;
1) when using USB to the motherboard, short circuit cap should be used to connect +5V and USB feet;
2) when the 12v-24v supply is used, short circuit cap shall be used to connect +5V and INT pins;
Note: it can be connected to both [12v-24v ] and [USB] at the same time. Short circuit cap must be used to connect +5V and INT in the printing process.

2. SKR motherboard through the [USB] interface and PC communication, need to install the driver to use normally.
1)Smoothieware-USB-driver-v1.1 driver installation. Drivers are available from the open source web at
http://smoothieware.org/windows-drivers
2)Open the computer "device manager", and you can see the COM number of "smoothieboard USB Serial" asynchronous communication port.

3. SKR motherboard description
The motherboard will be equipped with (I3 model) for testing, which can be used directly or can be changed according to your own needs
1)The SKR motherboard access method:
Log on to the open source site to download:
https://github.com/Smoothieware/Smoothieware
2) update method of SKR motherboard
Select the file suitable for your model from the downloaded package and copy it to the SD root directory, including:
①. bin (all that can be decided based on your own machine)
②Configuration file config.txt (you can change the configuration according to your own needs)

Thedetails of the configuration filecan be referenced in the open source web address:http://smoothieware.org/configuration-options

Note:


0. We have a small SD card for each motherboard. File names cannot be changed in the SD card. The file names cannot be changed, . the bin must be lowercase.

1. 5V SEL of the motherboard must connect INT and 5V pins before printing (that is, 12v-24v supply must be provided to the motherboard before printing);
2. Hot bed board receive must be less than or equal to 110 w (that is, the hot bed resistance is greater than 1.3 Ω), if with high hot bed, have to external thermal expanded bed plate;
3. The wiring process and plug-in driving process must be carried out under the premise of failure. The can be turned on after checking the correct connection of the line and the correct insertion of the drive, so as to prevent the wrong connection of the line from burning the motherboard and drive and causing unnecessary losses;
4.If you want to change the configuration file, backup the factory configuration file to record the pin number of each part of the , and then make changes to the new configuration file.
