Yet again I need help from my Forum friends.
I finally broke down and bought myself a Creality Hi combo 3D printer. (The combo has a unit that allows 4 color printing.)
My question comes from the fact that I tried to print an existing design (shrunk down) to make some benches for an HO scale park and library area. When I tried to print the pieces the first time some fine detail on the back didn’t print at all and some of the handrail was missing on the sides. I tried to change some settings by lowering some of them to see if I could get those details to print. Instead the pieces that were incompletely printed the first time didn’t print at all.
I have standard PLA+ filament and the nozzle is 4 mm.
What do I need to do to get those details to print? I am very new at this at completely stumped. Any assistance that can be provided would be very much appreciated.
Which slicer are you using–Cura, as I suggested (though apparently that doesn’t work with colored prints), or perhaps the Creality slicer?
I tried to use Cura and found it doesn’t have the H1 printer in its database. I am using the slicer in the Creality program.
there are smaller nozzles are needed for finer details. they also result in longer print times
If this profanity persists, I may have to flag this thread! 
Right, I forgot. Sorry!
I’m unfamiliar with the Creality slicer, but I installed it to take a look. I found this:
I’d recommend that you use a smaller layer height. Unless that’s what you’re referring to when you say
In Cura, when a model or part thereof is considered to be unprintable, it shows up in the preview as looking like the negative shapes in Tinkercad. In the Creality slicer, it simply disappears from the preview. Whether the part of the model is unprintable or not seems rather arbitrary. I’d recommend that you check the preview and make sure that your details are there. If not, I’d play with the settings until they do pop up.
Also, a 4 mm nozzle is huge! I assume that you mean a .4 mm nozzle? I don’t know the exact capabilities of the printer, having had no experience with the particular model, but I would assume that it should be able to do your benches with that nozzle.
???
Just joking at the use of all those strange terms.
Ah.
It probably is .4 on the nozzle. As said I’m new at this.
The layer height was one of the parameters I changed to make it smaller and that’s when the problem occurred.
I happened to watch a video talking about printing tools and it had a hammer where the infill needed to be increased to 100% to give it some weight. I had the thought to try to increase the infill to see if that might help.
Okay.
So, changing the layer height could have made the issue worse by confusing the printer more. In my experience, the infill probably wouldn’t affect it but it doesn’t hurt to try. Problems like this frequently require a lot of fiddling and a good bit of jiggery-pokery. Do you think that you could show me the file that you used (was it on Thingiverse, Tinkercad, etc.) so that I could take a look at it?
