Hello, I would like to know the Vref for the Creality Ender 3 stock stepper motors since the motors of the x and y axes get too hot (60ยบ celsius).
Any help is welcome
greetings VaroLabs
We have found that the temperature of the Y-axis motor will be very high. You need to set the current of Y to 650mA in the firmware, and the temperature will be around 50 degrees, but there is no lower than this!

Wow ... TMC2209 650mA (0.65 A) Irms are around 0.92 A Imax per phase. That is a lot for a 0.84 A stepper motor like a JK42HS34-0844 on a Ender-3. How long will this work? Without burning down the coils ...
eliwong_git After some tests this is working fine for me:
X: 580 Y: 480 Z: 600 E: 600
It won't burn the coils , don't worry.
Firmware updated , and this issue fixed already. Try the new firmware.
