This page is a dependency of the-> [Base Scaffold System](https://wiki.adom.inc/adom/base-scaffold-system) main page.- The control panel is the electrical front door of the Base Scaffold System: it carries the scaffold's power and signal interface and provides the connect/disconnect that mates the scaffold to a workcell each time it docks.  It is a two-board pair that mate at a blade dock. One half stays with the workcell, the other rides on the base scaffold with the project.@@ -48,25 +44,21 @@ scaffold control panel.
