The load fail red led does come on and stay on when I boot up linuxcnc and get the error messages. also the green estop ok led is lit as well. Prior to starting linuxcnc the light is off.
OH, didn't read closely enough! If you are saying the Load Fail LED only stays on after LinuxCNC starts? I know of NO WAY LinuxCNC can turn this light on, except by maybe causing a fluctuation of the 12 V supply.
Please give a bit more detail.
