I am not responsible for your damaged 3D printers and single board computers, I do not give advice, this information is provided as is, you can use it only at your own risk.
This procedure is necessary if you want to replace the original stepper motors with motors requiring higher currents. The image shows a detailed schematic and indicates which resistors should be used instead. I recommend using short, soft silicone wire (if you're installing a resistor or potentiometer on the wire).
I've used this circuit to connect other, more interesting stepper motors (such as one with a 0.9-degree rotation angle) to the extruder. Currently, I have a simple 17HS4401S stepper motor with a 0.9-degree rotation angle, and I replaced the 4.7kΩ resistor with a 13kΩ resistor, increasing the current from ~0.5A to ~1.3A.
Stepper motors are connected using a standard twisted cable. This cable may not be suitable for connecting stepper motors with a current greater than 1.1 A! (Even at 1.1 A, you will likely experience a significant voltage drop.)
