Turning off photons on the LEDs solved it for me, but I've hit another
issue.

I get warning messages like
       "Cannot use pass through with refraction and high density photons".

Not sure how I got to "high density" photons..  I do want refraction and
photons though.

Also, as part of getting through this, I added a "split_union off" to the
final object, which is a union of the printer, table, and a pen. Now I get a
warning that the camera is inside a non-hollow object.

Could it be that I'm inside a bounding box?
