I really do have to suggest being WAY WAY WAY WAY WAY careful with a project like this.<br><br>those lasers are not easy to deal with, and are severely dangerous.<br><br>be super super cautious.<br><br><div class="gmail_quote">

This sound interesting. Most importantly, I think we need a good,<br>
sturdy 3-axis gantry that can be used to move around a router, Dremel<br>
tool, LASER head, stencil cutting knife, etc.<br>
<br>
All of the systems I have seen so far (Reprap, Makerbot, etc) are too<br>
light to move something like a LASER system or a high-speed router for<br>
cutting out circuit boards/etc.<br>
<br>
And all of the heavy-duty movements I've seen have involved one-off<br>
salvaged components, like steppers+ball screws from a wrecked CNC<br>
machine tool or a large industrial line printer.<br>
<br>
So I would encourage the team to think about not making the platform<br>
100% specific to LASER cutting, but an open design that could have<br>
multiple components bolted on.<br>
<br>
A repeatable design for a nice, rigid 3-axis movement would be an<br>
excellent "Stage 1" design goal, even if the LASER portion proves to<br>
be harder to master.<br>
