I am confronted with poor knowledge of stepper motors [...]
When myself trying to be polite addressing topics in this context I met aggressivity and comments that attacked me on a personal level.
maybe it wasn't the polite thing, praising yourself as semiconductor specialist and after asking a question and got the hint about cheap chinese 3d-printer quality to disqualify the person who wrote the message as a "dampfplauderer" (german word for talking about things without knowing something about)
You dont even calculate with the right voltage numbers on your assumes on the current-regulated motor drivers, and dont even think about effective power and reactive power and apparant power

The higher the performance of the controller, the higher speed the printer can print while keeping the ability to do its control job.
so there is the next myth, because even the "slow" 8-bit MCU ATmega2560 are powerful enough for a simple cartesic printer, which is proven on thousends of machines out there.
The 32-bit hardware may be the better choice for delta printers, but it is on a lot of cheap chinese machines more about the cheaper prices ot little ARM SoC compared to Atmel MCU. And about controllers with colored displays, to have a point of selling.

You might understand now why I was so surprised, not to be aggressive as Germans often are, that even the support of BIGTREETECH seems to be ignorant about this. I have already sent 3 emails to their support to ask if when applying 48VDC to their "Motor Power" connection these are isolated from other parts of the circuitry of my board. Still, just the response that the board can only be fed using either 12VDC or 24 VDC. Sure, and I am aware of this, the circuitry in this board can only be fed with one of these 2 possible voltage values.
So in the 3dprintforums message board you said, the BTT was not so ignorant and gave you a good support, and now they are bad too?
How you got the knowledge about 12V voltage on 3d-printer stepper motors? It would be the first printer with this high voltage on motor coils.

Does anyone of you know if the Motor Power connectors are only passed to the VM of the sockets for the SilentStepSticks?
I do, but you said iam dumb in the other board. So find out yourself.
