Re: FYSETC S6 Motor Lock up

I don't think there are many sources of inexpensive NEMA 17 step motors. The red, green, blue & black color scheme seems to be universal among them.

The motor manufacturers are fairly consistent There is an A coil and a B coil. The coils are polarized so one end is "+" and the other is "-." Thus you will see this symbol which gives you most of the information you need.

Add a little color and it tells you all you need to know.

The problem arises with the driver carrier manufacturers. They can't seem to decide on a standard coding or which way is up!

Regardless of the inscriptions the hookups are all the same except the ST820. Some use the letter for the coil designation others the numeral. 

Most of the time, one of these will work.
