+Now it's time for the electronics, wiring, and firmware. Then it's time for the first calibration prints!
+==== Electrical ====
+Well, here it is; the super tedious part. Pictures of work in the mechanical section each represented about 30 minutes of work. Each of the following pictures represents about 1-2 hours of work.
+Mounted up the electronics to the acrylic panel.
+On the left is the power supply and the solid-state relay, and on the right is the Raspberry Pi and BTT Octopus mainboard.

+Shortened stepper wires and crimped JST connectors.
+The stepper wires included in the kit were too long and they were terminated with the wrong connectors. While they would have worked, the connectors would have been easily removed by mistake and the wires would have been a mess.
+{{:projects:ratrig3dprinter:pxl_20220515_210129938-min.jpg?400|}}
+Wired up the 24-volt power leads to the mainboard and the control leads from the mainboard to the relay.
