Index homing Heidenhain ls 403/exe602

If you  scale has periodic index marks you need to coarsely position
the axis before the final home to index (this is usually done with a home switch
but could be done by jogging to a mark and then homing to index)

What about the "rawcounts"? when i quickly had a look at them in halscope they seemed to have "0" at a fixed location, do you think that's something i could use in some way?

Raw counts will be set to 0 when LinuxCNC starts so its still
just a relative count number.

What is the spacing between index marks on your scale?

My Maho homes off the Heindenhain LS-403 scale index marks. Works the same as homing to a a separate homing switch.

Do you have the LS 403 scale or the LS 403 C? Could explain why I have some problems since the "C" is the Distance-coded version of the scale...

If the machine has no built in home switches, it really makes no sense to
have multiple index marks on the scale.

It it possible there is an electrical issue causing false index detection?

Is there documentation on the scale types?
