Description

Introduction of Mainboard:

Super quiet. Compatible with Creality Ender 3, Ender 3 Pro, Ender 5 3D printer. PLEASE NOTICE: It only plug and play for Ender-3 & Ender 3 Pro. If you want to install it on Ender-5, please flash Ender-5 firmware. You can download firmware here. https://www.creality.com/download

Driver – TMC2208 driver & Marlin 1.1.8 for V1.1.5 board while TMC2225 driver & Marlin 2.0.1 for V4.2.7 board. Bootloader preinstalled on both version boards.
Update Firmware – If the board you received is V1.1.5 please flash firmware with ISP cable. If the board you received is V4.2.7, please copy the firmware file to a formated SD card with no other files in it. Turn off the printer and unplug the power cord. Insert the SD card & power cord, and turn on the printer. Wait 10s to complete the firmware updating process.
Thermal runaway protection is enabled. The Board is Optimized by Circuit, effectively solve the Heating Problem.

Introduction of BLtouch:

BLTouch is a type of semiconductor hall sensor and is an electronic component for 3D Printers.

BL Touch is an auto-leveling sensor for 3D Printers that can precisely measure the tilt of the bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on.

BLTouch is fulfilled with simple structure and high precision by using progressively designed solenoid and hall sensors. It aims for user convenience and enjoyable printing by adding many smart functions, such as self-test, alarm, alarm release & Touch Switch mode, Blue LED for servo signal indicating, and Z-probe(Zmin) Testing.

Features:
The main functions and controls of BLTouch are the same as the usual auto bed leveling sensor, which consists of an RC servo and microswitch. Thus, BLTouch can be applied on almost every board.
Self-test： The push pin operates two times in a test when the power is on.
Alarm：The LED light blinks if a problem was found on a self-test or during operation
Wiring defect indicator：Blue and Red LED for indicating wiring defects.
Easy to Use: This auto bed leveling sensor makes it easier to level the hotbed, which can precisely measure the tilt of the Bed surface. Bed leveling is not a problem anymore.
Intelligence self – check and alarm: The function of auto leveling is adopted to make it easier to use and to increase the success rate of shaping.

Note:

Some 3D printer motherboards have insufficient 5V power supply and may require an external 5V power supply, which shows that the probe is difficult to push out, or the logic circuit protection main control restarts during operation.
