Hey! The instructions should probably say to do that, huh?
Okay, the instructions are updated. On mine, I can also get a ball-end allen wrench into the screw head, but it's a little awkward, since the head won't back out, so you have to lift the extruder block while unscrewing.

On mine, I routed the heater and thermistor wires to the rear and brought them out through the cutouts in the corners of the shelf brackets. That gets the wires clear of the servo probe.
