1. Киришүү
The BIGTREETECH SKR V1.4 Turbo is an advanced 32-bit control board designed for 3D printers, offering enhanced performance and versatility. It features a 120MHz ARM-class Cortex-M3 series LPC1769 main control chip, significantly improving processing capabilities.
This board supports various stepper motor drivers, including TMC2209, TMC2208, TMC5160, and TMC2130, and is compatible with TFT35 E3 V3.0.1/TFT70 touch screens. It incorporates on-board TMC-driven SPI and UART working modes, along with convenient DIAG function pins for simplified setup.
The included TMC2209 V1.3 silent stepper drivers utilize stealthChop2 Mute technology for quiet operation and efficient motor torque, generating lower heat compared to other drivers. With passive cooling, these drivers maintain optimal temperatures even during extended printing sessions.

5. Кыйынчылыктарды
Бул бөлүм сиз кабылышы мүмкүн болгон жалпы маселелердин чечимдерин камсыз кылат:
5.1 TMC Connection Error
If your display shows a "TMC CONNECTION ERROR", verify that all stepper drivers are correctly inserted and oriented. The board includes integrated anti-reverse driver protection, which prevents damage if a driver is inserted incorrectly. If a driver is inserted reversely, the indicator light for that driver will be off.
5.2 Heating Issues
The board features an advanced thermistor protection circuit to prevent short circuits between the heater cartridge and the bed heating element. It also includes an additional heater protection circuit (MOSFET) to guard against runaway heating. If heating issues occur, check the thermistor connections and the MOSFET for any visible damage or incorrect wiring.
