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


Awesome!! Thanks, I'll give this a try.

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


I'm not sure I understand this concept?

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?


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....
