I have a two-phase bipolar stepper motor rated on 4.2 amps per phase (parallel connection). The peak current draw for this motor: 4.2 A * sqrt(2) = 4.2 * 1,41 = 5,92 A.

I'm looking for a matching...

Ok, now I understand. Also, due to connecting the DC ground to the earth ground, the number of required probe wires could be reduced to 1 (the only required wire would be the +5V wire, connected to...

I'm not sure what do you mean by that. Are you suggesting using an optocoupler?

I want to design an automatic Z probe to my CNC machine. I was planning to do this basically by using 2 wires:
- first one clamped to the end mill
- second one connected to a copper plate
The +5V...

Hello,
I'm looking for a matching stepper motors driver for my motors.

My stepper is Nema34 with the following parameters in the bipolar parallel connection:
- 4,5 Nm of holding torque (about...
