Found some more info on encoders about timing and clock, but nothing more usefull, so a lot of testing tomorrow.
See attached pdf two posts up.

Tom

Do the numbers you have at the moment actually vary as the encoder turns?
Your 151554.185 doesn't seem like an obviously bogus number, but it would be hard to tell after scaling if it was (for example) all "1".

HI Andy,
Yes that is what i get, and i can see the pulses with halscope, tested for 3 hours today to get something useful out of it but no luck.
This is with the spimdle encoder, same typea are on all axis except the long X, but different revolution counts. Not to be mistaken for counts per revolution.
Axis encoders are 4096 counts per revolution and can count up to 4096 rotations.
Spindle encoder is 4096 counts per revolution but can count only one rotation.
Long X axis is 4096x4096 but has another wire fro direction.
Found the above attached pdf, so they are SSI and grey code, also the frequency is recomended to be at 200kHz. Nothing on the pulse train info.
Tested all i could think off but no matter what, it gives fuzzy readings, and at a certain point in rotation, it just stops sending pulses, so i gues it must be lower/upper type.
I did find another thread on this forum today explaining some other SSI encoders that had a different way of functioning in hal, active users were PCW, you, and another member. At first glance it looked way more complicated than the hal settings i am using, so i might give that a try in a day or two.
Thank you,
Tom

What is your config string at the moment?

And is it possible that the data is bit-reversed?

Well as PCW so nicely put it, i am in the dark, bumping into walls, nose first! 
I am having a coffe now so using the phone, i will attach the hal file, basicaly i used a section on the SSI encoders something something thread, started by Tero ( forum name Terkaa ).
There is a loadtr section with the ssi.1=xencoder%32ge and setings for clock rate etc and the fedback part in the X axis section.
