Product Introduction

3D printer MKS TMC2100 silent drive stepper motor drives independent send heat sink

Disadvantages:

1. Inherit the consistent features of German products, which are super expensive.

2. The operating temperature is relatively high. In the case of no fan, the operating temperature around 0.5A is 70 ° C, and the operating temperature of 1A exceeds 150 ° C, steps may be lost.It is recommended to do A good job in heat dissipation, and the best working current is about 0.5A.

Advantages: quiet (!+!)

Driving current algorithm and regulation

1, drive current algorithm: I =Vref*1.9/2.5, the default Vref is about 0.65V, so the default current is 0.5a, the maximum current is 1A!

2. Vref measures Gnd and voltage at middle end of potentiometer.

3. Do not connect the motor when measuring the voltage, or the drive will burn down easily.

4. Power should be switched on when measuring voltage, not just connected to USB power supply.

The use

1. When used on Ramps1.4 or MKS Gen, please remove the 3 jumper caps under the socket

2. Pay attention to direction

3. The heat sink is directly attached to the PCB

4. The motor direction is opposite to 4988 and 8825. If you want to directly replace 4988, please adjust the firmware or adjust the motor connection.
