BIGTREETECH S42C V1.1 High Speed Closed Loop Driver Control Board 42 Stepper Motor Prevent Multi-Step and Losing Steps with Low Heat Generation for 3D Printer (S42C V1.1+Metal Protective Cover+Motor)

Description

【NOTES】 Only suitable for motherboards with socket stepper driver installation. 0.9-inch OLED screen, the motor current and subdivision can be modified by buttons, and displayed on the OLED, the operation is simple and convenient; in the absence of OLED, you can use the serial port to connect to the computer, and use the serial communication protocol for parameter adjustment and query S42C V1.0 Closed Loop Driver Control Board Specification： Maximum speed: 2000RPM Main control chip: STM32G031G8U6, 32-bit ARM Cortex-MO+, clocked at 64MHz 【ATTENTION】 1 、When inserting the adapter board, please pay attention to the direction of the adapter board. Notice the motor and the loop chain wiring sequence! 2、For the first time, the closed-loop driver board must be connected to the motherboard with firmware, and then the encoder shall be calibrated. The calibration time will take 1-2 minutes 3、Check if the driver is installed when connecting to the computer with the serial port. 4、When the data displayed on the display or serial port is abnormal, please remove the closed-loop driver board and check if the magnet on the motor shaft is in the center position. If not, please return it to the center for recalibration. 5 、After completing the calibration, do not set it immediately after power-on. Please wait for the initialization to complete (1-2s) before setting the parameters. 6、Please do not manually turn the motor after power on. 7、The distance between the magnet at the center of the motor shaft and the core encoder should be greater than 2mm. 8 、Full stability of machine structure must be guaranteed

Features

• High-speed operation: Compared with ordinary drives, this motor runs more stable. Low heat generation and high operating efficiency. Can print at high speed without losing steps
• Precision improvement: Compared with S42B, the main control chip: STM32G031G8U6, 32-bit ARM Cortex-MO+, the main control chip detects the stepping out and compensates through the magnetic encoder, which improves the processing speed and accuracy of the machine
• Low noise and low vibration: Software algorithm optimization, motor running noise and vibration are smaller
• Convenient secondary loading: The set parameters can be saved, which is convenient for secondary loading, and supports direct control in UART mode
• Easy to install: The whole machine is sold, eliminating the need for complicated assembly and debugging. Easy to install and wire, plug and play
