Hello :)
The solder joint are all measured with Multimeter and have contact.
I have test three different 12v Power- Supplies (1A, 1,5A 3A) with two different 5V (2,5A 3,1A).
I have test it with 12(!) new Motor-Drivers (from two different manufactures)....
There are 12v on Vmot, on A1-B2 are between 0.2-0.8V, no signal on enable (on both Motor-Drivers).
Ihave Test it with 4 different Steppers.....(The are all 1,8° = 3200Steps)
The Lasers work, but the LED-Ring won`t (There are 5v on it, but no signal comes on the Data-Channel).
The Cable which comes with the LED-Ring have 4 Channels, but there are only three, so i have soldered pins there and took an own cable.
The Web-Server is reachable and works, but no moving on Preview or Calibrating.
I have no Idea where the error is.....

Ihave test it also with an Raspberry 3 B, B+ and Zero W (The picture and the Logs is from the Zero W, but the Logs and the errors are all the same at all).

Can you post a picture of your LED Ring (connectors) just that we can be sure that this thing is ok. And can you also give me more information about the motor drivers you are using. From the picture it looks like something as a4988 ...

 I recommend the 3B or 3B+. The Zero W does not have enough CPU power.

I think that the LED-Ring and Motor issue is not related to the Pi. In fact that you connected all things in a correct way there is a small chance that the responsible ports of the atmega on the pi HAT are damaged. But before we come to this conclusion we should have a closer look on the motor driver type and the led connector. I just need to know which hardware is used before i can give you more hints.

Hello and thanks for the fast Reply :)

The Motor-Drivers are full-A4988-compatible Step-Sticks. (both are optical similar and from Amazon, see picture)

Motor should be a UsongShine 17HS3401S with 1,8° deg 0,4A? (other Manufactures sell it with 1,3A and 43Ncm) 12V 26Ncm, but there is no Label on the Motor.

( https://www.amazon.de/gp/product/B07JN4V5VZ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1)

The Lasers are focusable Red-Lines with 650nm with 3-5v.

The LED-Ring ist the original Cam-Mount from Waterott

With the PICam V2.1 (nonIR) and 50cm Flex-cable.

The Power Supplies are measured before and works correct.

My Configuration with 3d-printed Parts is taken from the CebScan-Project.

I know that an 3b or 3b+ is recommend, but befor i crash some, i took an cheaper Zero W (I also have test it with 3b and 3b+, the errors are the same).
