Hi, my Robin Nano v3 just arrived, MKS TMC2209 v2.0 drivers includet. But I don't know what current my stepper motors need. The ons for the x-axis is labeled 'STEP MOTOR 42SHDC3025-24B' and I found...

The motor data sheet is 0.9 amps. There is no harm in going lower, if the motor will provide the torque you need.

Bear in mind that the current that can be absorbed by the 33 ohm resistor will be limited. For example, if you use a 24V supply then it's only about 700mA.

The diode is normally forward biased which holds the transistor off. When there's a voltage spike at the motor that exceeds the supply voltage (24V in this case), the diode gets reverse biased and...
