KINGPRINT TMC2130 V3.0 Stepper Motor StepStick Mute Silent Driver with Heatsink for 3D Printer Control Board 4 Packs (DIY)

Parameter Description：Highest Resolution 256 microsteps per full stepStep/DIY Interface with microstep interpolation microPlyer SPI InterfacestealthChop for extremely quiet operation and smooth motion spreadCycle highly dynamic motor control choppercoolStep current control for energy savings up to 75% Voltage Range 12V/24VDCPassive Braking and freewheeling mode Full Protection & DiagnosticsPotentiometer adjustment instructions:Rotate the potentiometer clockwise: lower Vref to reduce the drive current;Turn the potentiometer counterclockwise: increase Vref to increase the drive current the motherboard provides 12V or 24V voltage, the accurate voltage of Vref can be measured; Vref value range: default value: 1V (±0.2); maximum value: 2.4V; MIN: 0V;Do not use too much force when rotating the potentiometer to avoid irreversible damage to the potentiometer; when it is rotated counterclockwise to the maximum value, if it continues to rotate, it will become the minimum value; likewise, when it rotates clockwise to the minimum value, If you continue to rotate, it will become the maximum value;note :1 do the heat dissipation work (heat sink + cooling fan) before driving work, prevent driving Not working properly;Pay attention to the line sequence and IO port when wiring. Connecting the wrong line will directly cause the driver to not work.2. When inserting the drive into the motherboard, please pay attention to the direction of the drive, do not insert the drive incorrectly, and prevent the drive from burning out.
