New Design

[Yoonseo Kang]

Alright, after breaking some design assumptions we get a solid gantry
design proven to achieve at least 0.001" repeatability and can mill
not just circuit boards but even steel.

The general design can be exemplified by lumenlab's products:
http://micro.lumenlab.com/

Using aluminum blocks instead of HDPE, plus a better designed Z-axis
and spindle, prototype 2 of the CNC Circuit Mill should have amazing
performance.

Conceptual design found here: http://opensourceecology.org/wiki/CNCPlateDesign

Specific design (with all the dimensions matching up and confirmed)
currently in progress:

Will also use a brushless motor to drive the spindle for maintenance-
free, long-life operation.

hi yoonseo

holla this is complete different design, it looks realy easy and focus
on all the task which have to be done.

what is about the pricing.

you have a value?

and what material you wanna use for the blocks?

hi yoonseo

mhh it realy looks like the mill from that lumenlab

now we come to something realy interesting. whats about if somebody hase
an patent on such/andy design?

and under which lizenz the OSE typically produce there products?

I was thinking aluminum 6061-T6. The block design is really easy, only 11 blocks to make!

By my calculations going by onlinemetals.com, under 100$ for the aluminum.

Electronics are getting to be between 250-300$

Other hardware including leadscrews, leadscrew nuts, bearings, and fasteners, I think come to over 300 right now, but that's because I haven't searched for better hardware suppliers yet.

So for now 700+ excluding tools, but plenty of room for improvement.

As far as I researched, no patent on that general cnc mill design. It's just double-drive X-axis with blocks, so I didn't think so.

OSE has an OSE license.

Hey guys,

Just signed up to the mailing list, I want to help with the prototyping of this design. I have a 3D printer to help in the construction. I'm going to get started on printing out the blocks discussed in this design and put something together.

Sounds cool, be sure to keep us notified of progress. Right now I'm working on some design scalability issues and sourcing some electronics equipment in preparation for the build on-site here.

Cheers,
