The VS pin on my TMC2660 driver has fried, and I’m trying to identify the root cause

[kowthaman57]

I have been working in a 3D printer i used this stepper driver to my motor but it fried the Vs pin can anyone tell me the solution for this, i used Arduino due board for my work

here is my circuit . can anyone guide me and rectify the issues

The long, loose wiring is a serious problem, as is the use of breadboards, which are intended only for temporary experiments with low power logic circuitry.

1. The inductance of long power leads can cause large voltage transients, as discussed here: https://www.pololu.com/docs/0J16/all

2. Loose connections to motors can instantly destroy a motor driver, for the same reason. Solder all connections, or use secure screw terminals from motor to driver.

Replace the breadboards with a PCB or soldered connections to protoboards, for example this one.

There is space for an electrolytic cap on that board for that reason.
No cap fitted though.

I have limited knowledge about capacitors, so I would appreciate your recommendation for the most suitable one for my project. I am working with 5 stepper motors, and the circuit operates on a 24V power supply. Additionally, I’m looking for ways to reduce the number of wires in the system without replacing the customized Smoothie boards. Any tips or suggestions would be greatly appreciated
