There are grey scale absolute rotary encoders that are fairly cheap. I
think those would be a better test than linears since you have to handle
the wrap around accumulation. It would be a simple case to use a linear
encoder if the rotary worked.

Pretty sure the SSI interface works, but the BISS one requi

If there is demand, it is probably not a difficult one to write.
Like a number of other components, the problem is having hardware to
test

Hi,
Just wondering if there's any experience with absolute encoders and
LinuxCNC?
And particularly absolute linear encoders, with or without LinuxCNC.
Thanks,
