Higher voltage can extremely improve your printing speed and you can adjust it with a jumper cap. What's more, SKR 3 owns 2 normal fans, and the EZ version owns 3 normal fans, which can ensure the smooth operation of your printer and advance your printing quality.
  • 💡【Updates of Processor】The new processor of SKR 3 EZ controller is upgraded to 32-bit 550MHz ARM Cortex-M7 series STM32H723VGT6, with which the running speed and printing accuracy of SKR 3 controller is greatly increased by 30%+ while its working noise become lower. Its upgraded thermistor supports PT1000, exempting the need of external module.
  • 💡【Safe Anti-misplugging Design】Wrong installation of drivers will not only cause damage to the drivers itself but even ruin the motherboard or catch fire. And according to our survey, 40% Users may misplug the drivers unintentionally. Our new arrivals SKR 3 EZ motherboard and EZ series drivers, featuring an unprecedented anti-misplugging design, can totally remove such hidden dangers to offer you a better and safer printing experience! (Traditional TMC drivers is still compatible.)
  • 💡【Wide Application】Size: 18.5*19.8 mm, drive current 1.6A, peak current 2A, voltage range12 V- 24 V, 256 subdivision. BTT EZ2209 stepper motor driver can directly use with Mnata E3 EZ and SKR 3 EZ motherboard. EZ2209 can also well-matched with I3 Mega, Octopus V1.2, SKR 3 and other popular main boards by using BTT EZ driver connector.

First board I got all plugged in and wired then tried to power it on to flash with killer and got nothing. Fuses were good but did not come on. Took out and plugged in via usb and jumped the vbus pins and still no power. I left it for a bit then picked it up and the backside of the board near the usb port was much warmer. I didn’t pay attention but I believe it was a return already as the static bag was cut. I got another one that was in a sealed bag and plugged it in and it worked. Flashed it with lipped and a hour later was printing away. This replaced the board in my sidewinder x1. It’s like a new machine now!
