<br />Type: MKS TMC2100
<br />
<br />Dimension: 1.5 x 2mm
<br />
<br />The calculation method of driver current: i = Vref * 1.9 / 2.5
<br />
<br />Default Vref is 0.65V, Default Current is 0.5A, max current is 1A
<br />
<br />Most advanced mute stepper module, best choice to replace your A4988 or DRV8825 steppers.
<br />
<br />Equipped with a special designed heat sink to highly improve the heat dissipation.
<br />
<br />TMC2100 module adopts the most advanced chip to improve the function of the stepper which also makes the stepper can work silently.
<br />
<br />Instructions:
<br />
<br />1. When use in the Ramps1.4 or MKS Gen, or Lerdge touch screen motherboard, please remove the 3 jumper cap under the socket.
<br />
<br />2. Directly stick the heat sink on the PCB.
<br />
<br />3. The motor direction is opposite to that of A4988 and DRV8825, please adjust the firmware or motor wiring if you need to replace to A4988 or DRV8825.
<br />
<br />Notice:
<br />
<br />Please do not connect the motors when measuring the voltage, or it's easy to burn the drive.
<br />
<br />Please connect with both the power supply and USB Power when measuring voltage.
<br />
<br />Please pay attention to the direction, do not insert reversely.
<br />
<br />The working temperature might be high without fan. The working temperature is about 70°C when working current is around 0.5A, and over 150°C when working current is around 1A , which may cause losing step. In order to let the stepper work better, please keep the working current around 0.5A.<p> <b><b><img src="https://contestimg.wish.com/api/webimage/593173e9c5a85c47ceccb6a4-large.jpg"><img src="https://contestimg.wish.com/api/webimage/593173e9c5a85c47ceccb6a4-1-large.jpg"><img src="https://contestimg.wish.com/api/webimage/593173e9c5a85c47ceccb6a4-2-large.jpg"><img src="https://contestimg.wish.com/api/webimage/593173e9c5a85c47ceccb6a4-3-large.jpg"><img src="https://contestimg.wish.com/api/webimage/593173e9c5a85c47ceccb6a4-4-large.jpg></b></b></p>
