This engine is the one on the right side of the ship (starboard).
The front of the engine is where the (optional) crankshaft will be attached.
The back of the engine is where the flywheel will get attached.
HP stands for high pressure and refers to the second cylinder counting from front to back.
IP stands for intermediate pressure and refers to the third cylinder counting from front to back.
LP stands for low pressure and refers to the first and last cylinder.
Everything prints best at 0.2 mm height.
For the legs, make sure to block supports inside the base since it will be difficult to remove. Also make sure that bridging is set to a 45 degree angle such that the bridging distance is not too big at any point.
For the cylinders, make sure they are printed upside down. They have a small lip that is broken up on the lower side to ensure it fits with the lower covers. They should be up in the air. Use ironing on the top surfaces of the cylinders to make them smooth. They will print without support.
For the lower covers, paint on the support in the middle to avoid support being placed on the inner lip and in the hole for the M2 nut. Make sure to add filament changes for the first layer that embeds the M2 nuts in the parts. Also note that the IP Lower has a lower layer covering the nut than the HP or the IP Lower covers.
The upper cylinder covers are meant to get glued together after printing. This is to avoid support material that would otherwise lead to an inferior fit. Glue the complete cylinder covers only to the cylinders when you are happy with how the engine runs. Additional sanding of the cylinder blocks is basically impossible once the top or lower covers are glued on.
For the crankshaft pieces, make sure they are all being printed in a vertical orientation, holes down to the print bed. Tell the slicer to align the seams to the rear to facilitate sanding. Note that the center pieces are a bit wider.
The rods are best printed standing upright using all supports.
The crossheads are printed in their natural orientation.
The cylinders and valves are all printed standing upright. You need to turn them 180 deg looking that they contact the bed with their wide side.
The IP to LP steam pipes are printed best with their flat side touching the print bed. This may feel unnatural because it uses more support material but this way, the bridging works much better in my experience.
The stephenson bridge is printed best with the plat side towards the print bed at an angle that the first layer of bridging is at a 45 deg angle.
