<p>We have <a href="https://3dprinting.stackexchange.com/questions/1117/alternative-3d-molding-techniques-at-home">a recent question</a> that brings up the question of "<em>Should we support general hobbyist questions?</em>"</p>

<p>Currently, there doesn't appear to be a viable site within the SE network. The question at hand seems to be a mix between 3D Printing and DIY. If we allow this question, it could allow people to ask questions like the following:</p>

<ul>
<li>CNC Mills</li>
<li>Routers</li>
<li>Lasers</li>
<li>etc.</li>
</ul>

There is a
new question on Meta
that should help define what is okay on this site.
However, your question is important to address here.
Ultimately, you shouldn't be afraid to go ahead and ask the question. If the question does not meet the conditions of the present site, the general public will be sure to let you know and (hopefully) help direct you in at least asking a more direct question.
If you post a question that is closed, it would acceptable to post a question here on Meta that specifically asks how to make your question fit within the scope of the site.
I would suggest providing as much information as you have and feel free to ask the more general questions about 3D printing. Most people in the community will ask specific questions to try and help you. Some may even be able to fill in the blanks of what you're asking and provide you with very helpful answers.
