This is my power supply http://www.automationtechnologiesinc...upply/48v12-5a

I have the G540, connected with the DSUB ribbon to UC400ETH controller, then that goes Cat5 cable to a switch, and cat5 to my laptop.

When the fault occurs, the connection between the UC400ETH and Laptop and UCCNC program looks normal ( the G540 disables the servo's from moving, and the UCCNC software shows that the motors are still being told to move without any limit switch activation.
)

I noticed aswell, a little noise from the servo's when they are stationary and they are all connected, but less when there are 1 or 2 or 3 motors connected is this normal?

I've checked the resistors and they are 100% correctly installed, and re-wired the power supply to G5540 + and - with other 14G braded wire last night
