TMC2100 Stepper Motor Drive ultra-quiet Drive

MKSTMC2100 stepper motor driver board ultra quiet driver StepStick

First, the shortcomings:

1, inherited the German product has always been the characteristics of super expensive.

2, the working temperature is high, without fan case, about 0.5A operating temperature of 70 degrees, 1A operating temperature of more than 150 degrees, there may be lost step. It is recommended to do heat, the working current is best about 0.5A.

Second, the advantages: quiet (! +!)

Third, the drive current algorithm and regulation

1, 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!

2, Vref measures the voltage at the middle of Gnd and the potentiometer.

3, when measuring the voltage must not connect the motor, or easy to burn drive.

4, the voltage should be connected to the power supply, do not just connect USB power supply.

Four, use

1, when using Ramps1.4 or MKS Gen, please remove the three jumper caps under the socket

2, pay attention to direction

3, heat sink directly attached to the PCB

4, the direction of the motor and 4988 and 8825 on the contrary, if you want to directly replace the 4988, please adjust the firmware or adjust the motor connection.
