The problem I see is that your HAL file has all the PID terms set to 0:
P = 0.0
I = 0.0
D = 0.0
FF0 = 0.0
FF1 = 0.0
FF2 = 0.0
BIAS = 0.0
This means that the PWM value
(from the output of the PID component)
will be 0 regardless of position error

even with values for P & D ( 1.0 1.0 )
there's no effort to even start the servos

yes we changed P & D as soon as you said that before. It has had no effect. Could you take a quick look please; at the BIT file just in case there's still something wrong in there?

did you check the enables?

Yup, CNCBasher said they all look good from everything he can see.

Did you do this test:
To check the enables test for conductivity with an Ohmmeter between say ENA0+ (red lead) and ENA0- (black lead) These should show conductivity when LinuxCNC in ON

yes I have done that for both X & Y axis and it shows conductivity only in the one direction on both X & Y when I have the power on in AXIS.
Power off in AXIS and these drop to open circuit (no conductivity). But I'm not using the amps; and Friday you said these were for the amps. I'm using the Aout and ground and these are still producing 0v

what is the PWM value in hal? (depending on PID gain PWM scale and resolver these coul be very small)

if I had the right "PIN" that I was looking at, it was right next to the enable pins. The values were zero for both X & Y
Unless I'm not understanding your question?

What I was asking is in _HAL_ what is the PWM value?
