Description

1.Support machine structure: XYZ, delta, kossel, Ultimaker, corexy.2.Recommended software: Cura, Simplify3D, pronterface, Repetier-host, Makerware.3.Using powerful development tools, Keil MDK integrated development environment: support online debugging, more helpful for product development and performance optimization, using C language development, low development threshold.4.SKR motherboard firmware descriptionOur motherboard will be equipped with firmware (I3 model) for testing, which can be used directly or can be changed according to your own needs.1）The SKR motherboard firmware access method：Log on to the open source site to download：https://github.com/Smoothieware/SmoothiewareNote:file names cannot be changed, firmware. bin must be lowercase! We do not recommend using the TMC2130 spi on this board. If you really need to use spi on this board, you need to change the firmware by yourself, and we do not have relevant firmware to provide. In order to make it more comfortable for you to use, please directly use the STP/DIR mode of TMC2130.Attention:1. 5V SEL of the motherboard must connect INT and +5V pins before printing (that is, 12v-24v power supply must be provided to the motherboard before printing);2. Hot bed board receive power must be less than or equal to 110 w (that is, the hot bed resistance is greater than 1.3 Ω), if with high power hot bed, have to external thermal power expanded bed plate;3. The wiring process and plug-in driving process must be carried out under the premise of power failure. The power 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;
