Do: On an anti-static surface, pull all the voltage-selection jumpers, the four fan headers and the Z-probe voltage header, into a labelled bag taped to the bay wall. Do this before the board goes on the rail.
Check
Zero jumpers left in any voltage-selection header. Bag labelled and stored where Ch 10 will find it.
Helper Counts the jumpers into the bag, five in all, and writes its label.
What you're looking at
The Leviathan is this kit's mainboard: it drives all five steppers, both heaters, the fans and the endstops, and carries the Pi on top. The five headers arrowed here are its voltage-selection jumpers, each picking 5 V or 24 V for that output.
Caution
Rev D+ / LDO: LDO's rule, verbatim: "Remove all of the jumpers used for voltage selection prior to installation." and "Mixing voltage will permanantly damage the controller and attached components." Jumpers go back only in Ch 10, one component at a time, after each attached device's voltage is verified. src
Caution
Rev D+ / LDO: ignore manual p.174–178 entirely when you get there — that is Octopus jumper configuration. LDO: "Follow the instruction in the LDO guide for configuring the Leviathan controller board." src
