<p></p> <p><b>New page</b></p><div>== Use Guide TMC2100 Drive ==<br /> * Drive current algorithm: i = Vref * 1.9 / 2.5, the default Vref about 0.65v, so the default current 0.5A, the maximum current 1A!<br /> * Vref measures the voltage at the middle of Gnd and the potentiometer.<br /> * Be sure not to connect the motor when measuring voltage, otherwise it is easy to burn the drive.<br /> * Measure the voltage should be connected to the power supply, do not just connect USB power supply.<br /> * When using the Ramps1.4 or MKS Gen, remove the three jumper caps under the socket<br /> * Note the direction, refer to the above figure.<br /> * Heat sink directly attached to the PCB, refer to the following figure.<br /> * Motor direction and 4988 and 8825 on the contrary, if you want to directly replace the 4988, please adjust the firmware or adjust the motor connection.<br /> * For further details, refer to the TMC2100 data sheet.<br /> &lt;gallery&gt;<br /> TMC2100_direction.jpg | Noice the board direction, wrong direction will burn all boards.<br /> TMC2100_direction_02.jpg | Noice the board direction, wrong direction will burn all boards.<br /> File:TMC2100_direction_03.jpg | Heatsink directly stick on front side of PCB<br /> &lt;/gallery&gt;<br /> <br /> <br /> [[category: Stepper Drive]]</div>
