This How-To considers you want to keep the original firmware of your i3 Mega, and want to be minimally invasive. If USE_VREF is enabled, the TMC2209 will utilize BOTH the Vref voltage and the UART current command to determine the current to output. If you are using an operating current (Motor Current Rating * Operating Current Setting/100) > 740mA, there is no reason to enable this function. Trinamic Motion Control company manufactures both TMC2208 and TMC2209 VREF calculators. Despite trying to complete an older design, there was enough info on this site and these forums to get through the whole build without any real issues, which is a testament to the design, info, and support available here. Heat creeps can happen anytime, without your knowledge. Expect the X, Y, Z VRefs to be at 1.1 volts and E Vref to be at 1.2 volts.
