That's a terrific image. That was a 12 cylinder version, but a similar era. It has the outside the heads fuel distribution pipes that I've added. I don't know if I have enough head room to have the engine hanging above the engine. That's directly the result of the very large-girdered overhead crane that I chose to model. I think I'm going to draw the engine block as a bare block with open cylinders and access hatch openings. It could be neat to weather it and have it on cribbing outside.
The Elegoo, from what I understand, only gets fed by a thumb drive plugged into the port. I haven't tried to do it directly, nor do I intend to. I also found, strangely, that the Machine didn't recognize print files that I saved on the thumb drive's root directory. When I first turned it on and put my first file on the root, it couldn't find it. I thought there was an error. Then I found the Rook on a separate subdirectory and it found it and printed it perfectly. I moved my file to that sub-directory and it found mine too. I've got a sub-directory called "3D Prints" on both thumb drives I'm using and have no trouble with the Machine finding them.
Did some errands today so didn't do much, but what I did do seems to have found the limits on tiny prints. I grew four machines: the surface grinder - Came out okay, the metal band saw - All good except that I forgot to thicken the bottom plate of the chip pan and it basically doesn't have a bottom now, an acetylene welding set - really flimsy and the wheels are falling off even after I used Bondic to reinforce, and a Lincoln Electric MIG welding setup - this print was close to ridiculous.
Still having problems with hand wheels, but these almost worked except for the angled one. On the MIG Welder, one set of hoses actually is still there. The other was so fine that it couldn't hold itself together. Magnet wire would be better. Sometimes metal just is the better material. Even without the chip pan floor, I will use the saw as is, but correct the drawing for anyone else that wants this file. I do not recommend making the MIG welder. It's just too diminutive to be practical. I'm happy that I was able to correct most of the problems with the saw.
Then I printed some furniture. The cabinet and shelves worked fine. The work bench and shelves was almost a disaster. I had doubled the thickness of the legs and added some X-bracing, but I forgot to thicken the shelves. They came out paper thin. The first shelf barely printed at all. The legs were too flimsy. I need to make them square and add more triangulation to stiffen it all up and then it will work. Once again, things you get directly from the SketchUp 3D Warehouse don't work until you mess with them.
Right now I'm working on a floor drill press. The piece looked pretty good when I first examined it. Then I zoomed in closer and found that the knobs on the ends of the three handles were all reversed. So I fixed those. Then I looked at it bottom up and found that the drill press table was not a solid. The outer portions were solid, but the space between the bracing was unfilled. The whole table would have been a flop. I have to made the handles about 3X thicker than drawn or they won't work either. Upon even closer inspection I found that the circular area at the base of the knobs was open… no face. The knobs would have failed even though I got the faces correctly oriented. I had to zoom in very, very close to see this. The lime green from the insides of the ball caught my attention. I thought it was a reversed face, but then noticed there was no face at all and I was looking at the knob's interior.
I've said this before: 3D resin printing shifts the emphasis from crafting or making to evaluation, analysis and drawing.
Happy Labor Day Everyone! Be safe and have fun!
