lol  Yeah   

My HOn30 trucks:

The supports are on the bottom. I put most of them right on the bottom bolt heads so when I snap them off I'm done. The brake beams are pretty this so what I did was slice the supports off the end beams and then "rip" the rest off all before curing.

I didn't see the screw in the hole and had screwed in the spare in the hole on top of the first screw.   

While I very well might have made the same mistake I would not, NEVER, have admitted it in public.   Glad you got it and anxious to see what you're brewing.

I know some of the things I'll be checking before to hit the on switch.   Thanks, guys.

What can I say.   I have no shame. 

Success!  And failure!

The parts aren't there,  but those are the most beautiful supports you've ever seen.  I didn't know how many supports I'd need so I tried three kinds.  I guess none of them were enough. The smallest is what the slicer recommended.   Next time I'm going taller starting point with more supports.

In my post about my box car doors failing, that what it looked like. 

I would stick with the medium supports until you get a successful print.

My last print re-set the machine at the first layer again and the one I just started printing did the same thing. Will have to re-check the plate for level when it's done.

New USB's showed up, but the machine is running now so I don't know if they work yet.

...so what I did was slice the supports off the end beams and then "rip" the rest off all before curing.

Interesting. So is the uncured model a bit softer than a fully cured part?

Yes slightly.

Chris,

Did you print the trucks flat or tilted?  I have a truck project I want to do so this is encouraging.  When you print the next set of trucks, could you take a pic before removing the supports?
 

[Chris333]

Crap I just made another 4 trucks. More to come so I'll get a pic. These 4 were printed flat and about 1/8" up on supports.

But I have other pics. Top and bottom of a truck.

Interesting how you attached the brake beams. Usually these hang from bars that run across the ends of the trucks near the top. Perhaps something to consider in future iterations (or not).

[Chris333]

This car didn't have the bars, they hung from the car it self.

36" N scale wheels are 20" in HO, so my wheels are undersized.

I love it!  It'll be a learning curve but it makes sooo much possible.

FWIW most model narrow gauge trucks I see (Grandt Line, Blackstone, etc.) have the brake beams attached from the bottom as Chris has them.  I imagine there's some structural reason for the model to be that way.

I imagine it's to do with how the tooling is/can be made. The huge advantage of 3D printing is that all of those restrictions go away completely.

I thought it had more to do with clearances between the top of the truck and the car body, especially allowing for truck swing.
