Purge wall location

[Dennis Muhlestein]

I think I already know the answer to this but I was wanting to see if anyone had a suggestion.

I have a long part.  It fits on my print bed but not a lot of extra space on the ends.  I'd really like to use a purge wall but have the wall run on the north/south instead of east/west so to say.  Anyway, doesn't seem like that's a possibility really as you can extend the wall along the x axis optionally but you can't really choose to not do it on the y axis as far as I can tell.

I think it's mandatory on the Y axis because that's the section that actually wipes the alternate nozzle. If you're not using the purge wall as a wiper, you can just add some stretched-out calibration boxes as purge towers. Not as good but still works. I think there's a way to position purge towers around the part to make sure layers start with a tower (in front and to the left? both sides?) but I haven't tried it.
