2.The PCB board layout is rigorous and beautiful, and it is specially designed for heat dissipation.
3.Motor Driver: Supports TMC2208, TMC2130, LV8729, DRV8825, A4988Etc., can be externally connected to the motor drive. Recommended software: Cura, Simplify3D, pronterface, Repetier-host, Makerware.
4.Motor drive interface: X, Y, Z, E0, E1, five channels (each channel has a re-expandable interface), up to 256 subdivisions.
Note:1.After the SKR motherboard is powered on, the red light D4 in the lower left corner will light up, indicating that the power supply is normal; The middle of the board 5V SEL is the power supply selection end;
1) when using USB to power the motherboard, short circuit cap should be used to connect +5V and USB feet;
2) when 12v-24v power supply is used, short circuit cap shall be used to connect +5V and INT pins;
Note: it can be connected to both [12v-24v power] and [USB] at the same time. Short circuit cap must be used to connect +5V and INT in the printing process.
- BIGTREETECH SKR V1.1 motherboard is Shenzhen Bigtree Technology Co., Ltd. The 3D printing team has introduced a cost-effective 3D printer main control board for some problems in the market. It is especially suitable for small and medium-sized printers.
- The performance of the ARM-class Cortex-M3 series LPC1768 master chip with a 32-bit main frequency of 100M is greatly improved;Equipped with highly modular open source firmware Smoothieware, convenient for users DIY and secondary development, do not worry about the inability to master the core code of worries.
- The configuration file is used to set the driving current mode, avoiding manual adjustment of the current to cause the burned drive, convenient, safe and reliable;High-performance MOSFETs provide better heat dissipation.
- 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.
- Support Display : 2.8-inch, 3.5-inch color touch screen, LCD12864 screen;Support functions: Non-trace resumption after power off, run out filament ,and auto shut down.
