24 hours wasted. Plus I need to go back to the model in Fusion and make the trim at the wing windows thicker, they break off very easily.
The print turned out pretty good. I used blue, black, silver, and red Bambu Lab PETG HF and installed an E3D ObXidian High Flow 0.4mm hotend on my Bambu Lab P1S. While I was at it I replaced a screw that I had tried to put back in the tool head when I had it apart last year to fix an issue I had. I'd dropped the screw and it was just gone, I couldn't find it. So I ran the printer for a better part of year without it. Anyway, back to my story.
After I installed the E3D hotend I tried testing it, the hotend fan was D.O.A. So I had to remove the E3D hotend and steal the fan off my Bambu Lab hotend and swap it onto the E3D hotend and install it a second time, this time the test passed.
I loaded the four filaments I wanted to use into my four B unit AMS slots, three of the rolls came on spools, one was a refill so I pit it on a spool, I have lots of spare Bambu spools because sometimes the filament I want from them isn't available as a refill.
I loaded the stl file into Bambu Studio and painted everything that I didn't want to be blue, either red, silver, or black depending on the part. I then tilted the model backward 45 degrees, told the software to add supports and sliced the model.
I upped the volumetric flow to 35 cubic mm3/second. The software told me it would take 1 day, 4 hours, and 44 or so minutes to print. I knew it would take a long time because of the over 744 filament changes the printer would make. I cleaned the bed, went to my computer and sent the sliced file to the printer. Things were looking great but four hours in one of the supports fell over and so did the purge tower. I stopped the print, waited for the printer to cool, cleaned up the mess, and reset the slicer to its default volumetric speed for HF PETG filament and E3D hotend and tried again. This time I got a usable print, I broke the wing window frames on both sides but I was happy with the result and would totally have been okay using it with the broken frames, but I'd failed to include the front cab mount in the stl file so I can't use the cab anyway and the mount has to be embedded into the front of the cab model in Fusion because that area of the model has complex curvatures and is a bit thin, so printing the mount separately and gluing it on wasn't really an option. So, I'll be printed the cab for the third time. But I'm going to add a bit more thickness to the wing window frames and I'm going to print it slow and in a smaller layer height than the .2mm per layer I printed the cab in, and I plan to turn on ironing to give the top area a more smooth appearance.
The cab is otherwise a perfect fit, and I think I got the scale right where I needed it.
I need to order some longer servo cable extensions than the cable extensions I already ordered for some of the servos then star laying things out in the electronics tray before using double sided tape to stick stuff down.
I'm very happy with my results though.
I used tires to hold the front of the cab up to take the photos.
