## Overview

The BIGTREETECH S42B V2.0 is a closed-loop stepper motor driver control board designed for 3D printers with replaceable stepper drivers. Featuring a powerful STM32 Cortex-M3 chip, it supports up to 1000RPM with stable, multi-step prevention and low heat output. The V2.0 upgrade adds a CAN interface for improved connectivity. It includes an OLED display for easy monitoring and calibration, making it a cost-effective, high-performance solution for professional-grade 3D printing setups compatible with SKR V1.3, V1.4, and Turbo boards.

## Description

{Something important you need to know} Only suitable for motherboards with socket stepper driver installation(For Example, SKR E3 DIP,SKR V1.4,SKR V1.4 Turbo and so on) Can not suitable for integrated driver motherboards(For Example, SKR mini E3) S42B V2.0 Closed Loop Driver Control Board Specification： Motor power supply (VM): 12V---24V Default working current of the motor: 800mA Drive subdivision default: 16 subdivision Subdivision number: 2 4 8 16 32 Maximum current: 1650mA Maximum speed: 1000RPM Main control chip: STM32f103cbt6, Crotex-M3, clocked at 72MHz {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, please wait patiently. 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!! {Packing List} S42B V2.0 Closed Loop Driver Control Board whole kit*1

Review: Don’t buy !!! - No instructions included (found some Info on alibaba), board adapter wrong, not all pins connected (included VCC), therefor wrong labeling. Impossible to get it to work if you are not into electronics big time (including soldering the adapter). I could calibrate it, but it would not take my 5v step pulses !!!
Review: Great product, can't fault it BUT MAKE SURE YOUR MOTHERBOARD HAS REPLACEABLE STEPPER MOTOR DRIVERS - This is a great product but they don't come with instructions. You will have to search for YouTube videos as to a) check if your 3D printer can use them and b) how to install them. It was only after I bought my two and THEN looked for instructions on how to install them, that the very FIRST thing I should have checked, was if my 3D printer had removeable stepper motor drivers on the motherboard. The Geeetech A30T does not :-(

## Features

- {What is difference from S42B V1.0}Upgrade S42B V2.0 add a new CAN interface compare with S42B V1.0.
- {Cost-effective}Compared with ordinary drive, the motor runs more stable with more cheaper price.
- {Prevent Multi-Step and Lost Step}S42B Closed Loop Driver Control Board can easily deal with Multi-Step and Lost Step when during printing, No step loss in high-speed printing, low heat generation and high operating efficiency.
- {Easy to use in a whole kit} easy to use by the whole set with Stepper motor and OLED display, it will be installed well before ship out.

*by P***I on 27 March 2021*

Wo fange ich am besten an. Das Bild zeigt wie BTT dieses Set an mich geschickt hat, ein Kurzschluss gelötet. Leider fiel mir das nicht auf weil ich bisher von BTT sehr überzeugt war. So diese Kurzschlusslötstelle hat mein SKR Turbo Board aufrauchen lassen und ebenso 3 TMC2209 und einen ANTCLABS BLTouch sowie einen der S42B Stepper, der Support von BTT ist nicht in der Lage einfachstes Schulenglisch zu verstehen und wartet ständig mit den selben Fragen auf. Es dauerte nun 9 Wochen bis mir dann lediglich das SKR-Board und ein S42B Stepper geschickt wurden. Mein BLTouch und die TMC2209 sind noch immer defekt und ich sollte nun auf den fast 80 Euro dafür sitzen bleiben....sicherlich nicht..... So dann zur Qualität der Stepper. Die Stepper entbären jedweder Logik und die Elektronik darauf ist Mist. Es gibt bereits Nutzerprojekte auf GitHub welche die komplette FW ersetzen auf den 2.0er Boards. Auch Steps sind den Motoren anscheinend fremd, bei theoretischen 2333.34 Steps mit einer 1,5er Steigung sind bei den S42B Steppern 2760.82 Schritte nötig!!! What the heck? Sie sind auch unglaublich laut, von wegen super silent wie damit Werbung gemacht wird....die Teile sind lauter als alles je gehörte mit originalen Treibern.... Ich distanziere mich künftig von allen BTT Produkten und rate dringendst davon ab! Für mich ist die Firma am aussterben und will noch Kohle machen oder es passt was ganz gehörig nicht in dem Laden. Ich möchte nochmal explizit darauf hinweisen dass die Steps von links zu rechts um über 210 variert haben, das zeigt wie unpräzise diese Stepper gefertigt werden bzw wie schlecht die Technik darin ist... Der Support ist wirklich unterste Schublade, es wird jede Möglichkeit genutzt den Käufer falsch zu verstehen und am liebsten wird einem nur Schund erzählt. Zuerst hieß es mein Mainboard sei schon auf dem Weg zu mir, nach über einer Woche hies es dann es sei verloren, danach hieß es, es wäre mir schon zugestellt worden und danach wiederrum hieß es man hätte das falsche geschickt, aber es kam nichts an 8 Wochen lang. Das versprochene Controlboard für den S42B Stepper sollte auch schon längst hier sein, aber Fehlanzeige... Ich solle nun zu ANTCLABS gehen und mir dort den BLTouch ersetzen lassen sowie die TMC beim zugehörigen Verkäufer.....klar die freuen sich Zeug auszutauschen das andere kaputt gemacht haben.... BTT niemehr wieder, und ich nutze seit 5 Jahren BTT Equipment, Entschuldigung, nutzte....
