Very clean prints! What you see in the pictures is how it came out, no cleaning necessary! No purge tower, no shell, no ram purge, the extruders just wipe on their way out to their side and wipe again on their way in against fixed wipers on each side of the bed.
I have the Nimble too, just haven't gotten to install it yet. A quick question, what did you do with the IR sensor? Is it on the bed or one of the carriages?
