I just received 2 days ago a sr6+ with a t-valve, but i think i have encountered a problem, I dont understand how the twist work. Let me explain, i have 2 cable that i can plug something in, one with “twist” written on it, and the other nothing (i assume the t-valve) when I plug the twist, I try to change the range in mfp to test it… nothing happen. I could put a script nothing will make it move. So i tested to plug it in the other one, the one with nothing written on it. I test it… still nothing, so with desperation it try to change the range of every other axis, everything work but out of nowhere when i move the up and down axis the twist rotate in sync… im scared i did something wrong or it just doesnt work like it should. If anyone know something about it and could help me pls 
Check polarity. Black wire from the servo should go into the black wire of the female connector.
Check if this is turned on in MFP
