# STRIDEMAX_DUAL_FD_V2

![](https://raw.githubusercontent.com/FYSETC/wiki.fysetc/main/docs/images/crisp/stridemax-dual-fd-v2--figure-01.png "=800xauto")

## Introduction
StrideMax Dual FD is a RP2040-based control board with dual TMC5160 drivers that can run RRF firmware or Klipper firmware. Each 5160 driver group has 8 high-power MOSFETs and is covered by a heat sink. It also provides two fan positions for expansion, so that the drive current of each channel can reach 10A, and it can easily drive an 86mm stepper motor. Two TMC5160s have a separate 12V power supply, which can greatly reduce power consumption and heat generation under high-voltage working conditions. StrideMax supports USB/CAN/CANFD multiple communication interfaces, and can be flexibly configured and used with RRF and Klipper firmware. It is very suitable for high-speed 3D printing and high-torque CNC driving needs.

## Installation
### Power Supply
For the drive to work properly, the following prerequisites are required:

* It is recommended to use a 19-55V regulated power supply, which is determined according to the motor.
  
* Appropriate control signal source, such as control board, PLC, etc.;
  
* A matching stepper motor.
||| **Warning**
The limit voltage of the driver is 60V, which does not mean that the 60V power supply can be directly used for work, because the voltage may rise instantaneously when the power is turned on or the motor is working, which will damage the driver
|| **Note**
* If you want to ensure high efficiency and low noise at the same time, the driver power supply voltage should be at least 5 times the rated phase voltage of the motor (i.e. the rated phase voltage of the motor)Flow × phase resistance).
* If better high-speed performance of the motor is required, the drive supply voltage needs to be increased.
* If a regulated power supply is used, the supply voltage must not exceed 50V.
* If using an unregulated power supply, the required voltage should not exceed 34V. Because the rated current of the unregulated power supply is the full load current; when the load is very light, such as when the motor is not rotating, the actual voltage is as high as 1.4 times the rated voltage of the power supply.

## Connect The Motor
**Direct connection:** connect B1/B2 to one phase of the motor, and A1/A2 to the other phase of the motor;
|| **Note**
**Parallel connection method:** generally used in occasions where the rotational speed is required to be fast and the torque is not required to be high;

**Series connection method:** generally used in occasions where the torque is large and the rotation speed is not required. However, during the use of the series connection method, the current passing through is relatively large, so the heat generation will be larger than that of the general parallel connection motor. (Generally, it is normal for the heating temperature of the stepper motor to reach 90 degrees)
