BIGTREETECH EZ2209 Stepper Motor Driver

Easy Driver is a new driver from Bigtreetech. Thanks to its thoughtful design, the driver is easy to install on the motherboard. The EZ driver design has removed pins that often bend during installation due to human error, preventing proper device installation. EZ drivers are characterized by a long service life, thanks to the technology used to connect them to the motherboard.

Feature description:

StealthChop is a chopper mode used to reduce motor noise in TMC2209 drivers, improving motor efficiency. It works by reducing the current in the motor when the motor is not in use, resulting in quieter operation and lower power consumption.

SpreadCycle is a motor control technology that is part of the TMC2209. It is used to achieve higher motion dynamics and better motor torque at low noise levels. SpreadCycle consists of two parts: a chopper and a current controller. The chopper converts the motor current into a pulsed current, which is used to control the motor. The current controller allows for fast current control, enabling high motion dynamics. In addition, SpreadCycle can be combined with StallGuard technology for sensorless homing.

StallGuard is a function of the TMC2209 motor driver for sensorless homing. It monitors changes in motor current and allows the driver to detect when the motor has stalled, returning the printer to its home position. This function ensures print accuracy and prevents motor damage.
