Bigtreetech motherboard, 48V, Marlin Klipper software, used

【48V Fast printing】 The SKR 3 EZ motor voltage varies from 12V to 48V (it is necessary to use the EZ5160 PRO for 48V controller), while SKR 3 operates in the range from DC 12V to 24V. Higher voltage can significantly increase the printing speed that can be adjusted using jumper. What's more, the SKR 3 has 2 standard fans, and the EZ 3 version of the fans, which ensures smooth printer operation and improves print quality.

【Safe design that prevents bad connections】 Incorrect driver installation may not only damage the controllers, but also to destroy the motherboard or cause a fire. According to our research, 40% of users can accidentally connect drivers. Our new SKR 3 EZ mainboards and EZ series drivers with an unprecedented protection protecting system completely eliminate such threats, providing safer and better print experiences! (Traditional TMC drivers are still compatible.)

【Processor updates】 The new processor in the SKR 3 EZ controller has been updated to the 32-bit Arm Cortex-M7 series of the STM32H723vGT6 series with 550MHz frequencies, which increases the speed of operation and The accuracy of printing the SKR 3 controller by over 30%, and also reduces the noise level. The updated thermistor supports PT1000, eliminating the need for an external module.

【Firmware】 SKR 3 EZ disc is compatible with three popular firmware: Marlin, Klipper and REPRAP, which are widely used in the world of 3D printing. First, download the firmware called "firmware.bin" from Githuba, copy and save on the SD card, and then insert the SD card back and wait 10 seconds. When the status indicator stops blinking, and the file name on the SD tab will be changed to "firmware.cur", the update will be successful. Note: Our control plate is not delivered with the SD card.
