Awesome!! Thanks, I'll give this a try.
I'm not sure I understand this concept?

As I explained above, the ferror ini parameters _can_ be changed in real time

another option suggested by cradek on irc is to use homing to index
(jog to mark perhaps near middle of travel) and then home to index

To throw another option into the mix...
The f-error limits are triggered when the axis.N.motor-pos-fb pin value is too far from the axis.N.motor-position-cmd value.
You get no f-error at all if you connect them directly together.
So, you could use a mux2 component to connect axis.N.motor-pos-fb to _either_ encoder.N.position _or_ axis.N.motor-position-cmd based on the value of axis.N.is-homed....

It seems like the safest way to handle this is to expect the following error and to ignore them on homing commands. Is there a way to do that?
