I want to use my Atomstack R1 set with my Gweike G2 once I get it, but have only been able to find very little info on how the rotary-cable has to be connected to the USB-cable.
A cable from a keyboard has white, black, red and green wires.
Anybody have a picture of the correct order in which to connect them to the Atomstack connector?
Appears to be a standard NEMA motor. Likely two phase.
The Atomstack has motor driver circuits on board the controller. The Gweike has a Ruida controller, that just outputs step and direction signal to the motor drivers. The Gweike uses it’s Y axes motor driver to control the rotary, as far as I know.
My suggestion is to make a cable with Gweike connection type on one end and the Atomstack type connector on the other.
Both of these likely work using two phase motors. You can use an ohm meter if the phases are not marked on the motor, follow those back to the motor driver.

You could still run into the issue where you have a smaller NEMA motor on the rotary than you do within the machine… so there would likely be maximum current limits.
Make sense?
I can’t tell you, but you might be able to sumise what is what.
If you have a working cable, check to see what wires go to which of the two motor coils.
That same pair or coils go to the driver. All you have to go with is two pairs of wires going to two coils or a pair of wires/coil.
Maybe @misken has a more intimate knowledge of these and can help you out here… Give him some time to chime in..
You can determine the order by trial and error. It does not break anything when connected in the wrong order. A fast test is to connect two of the wires with each other, and then turn the motors’ axis. If it turns more difficult than without the wires connected, you found the connections of a coil.
