 Laser cut the electronics panel from 1/4" clear acrylic. Attached to the electronics inner frame and attached that to the outer frame. Getting the frame fully square was difficult and required a fair amount of loosening and adjusting the assembly to get everything together correctly.

 The next step is attaching the linear rails and assembling/mounting the X gantry. It's starting to actually look like a 3D printer now!
+=== 05/02/2022 - 05/06/2022 ===
+Prepared the linear rails. These are held in with M3 bolts and T-nuts that slot directly into the aluminum extrusion.

+Mounted the linear rails. It was very important to keep the rails square with the frame. Any deviation here can result in print defects.

+{{:projects:ratrig3dprinter:projects:ratrig3dprinter:pxl_20220502_024057013-min.jpg?400|}}
+Prepared and mounted the X gantry. This is the only part that uses 20mm aluminum extrusion.

+{{:projects:ratrig3dprinter:projects:ratrig3dprinter:pxl_20220504_030243863-min.jpg?400|}}
+Prepared the bed arms and mounted them to the rails.
+{{:projects:ratrig3dprinter:projects:ratrig3dprinter:pxl_20220506_021700234-min.jpg?400|}}
+Prepared and mounted the bed. This uses a very clever design that allows for only outward movement from thermal expansion to prevent bed warping.

+Began work on the EVA carriage. This is a modular design that allows for several different hotends and extruders so if I wanted to change to a different component in the future I could.
+{{:projects:ratrig3dprinter:projects:ratrig3dprinter:pxl_20220507_030729535-min.jpg?400|}}
+Once the hotend components are complete it will be time for electronics and firmware!
+=== 05/07/2022 ===
+Here's probably the most expensive part of the build by weight: the hotend. This is a Slice Engineering Mosquito Magnum. Also included were a couple orange flavored suckers.
+{{:projects:ratrig3dprinter:pxl_20220507_153705972-min.jpg?400|}}
+I had to open up the extruder to add in some square nuts for mounting. This also gave a great opportunity to see how the extruder gears and tensioner are arranged.
+{{:projects:ratrig3dprinter:pxl_20220507_162125482-min.jpg?400|}}
+Mounted the hotend and extruder with a small piece of PTFE tube between them to guide the filament.
+{{:projects:ratrig3dprinter:pxl_20220507_162948726-min.jpg?400|}}
+Then the cooling fan and shroud. This part is really begging for some googly eyes.
+{{:projects:ratrig3dprinter:pxl_20220507_180159567-min.jpg?400|Yes it will get googly eyes later}}
+Added the part cooling fan and cable management bracket.
+{{:projects:ratrig3dprinter:pxl_20220507_181110474-min.jpg?400|}}
+And that's it! The printer is mechanically complete!
+{{:projects:ratrig3dprinter:pxl_20220507_181208802-min.jpg?400|}}
+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.
+{{:projects:ratrig3dprinter:pxl_20220511_015949860-min.jpg?400|}}
+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.
