Upcoming changes/improvements:

-Separate DXF into multiple files (no layers).
-Incorporate Dremel 300 profile into Z-sled.
-Fix Y-belt holes to align properly & prevent rubbing.
-Modify Z-cart tensioners for easier adjustment.
-Conversion to metric hardware.
-Update instructions with link and/or content to HobbyCNC board assembly instructions.
-Update instructions with link to pre-assembled HobbyCNC Boards

Do you know of most of those changes are in the CNC files that one of the members have provided? Can't wait to get this thing started.

Chris, in your last post you published the upcoming changes/inprovements. Will they be published soon ?
Thanks for sharing the design !

Well, soon could mean different things to different people :)

Seriously, though, we're trying to plan for a second-version release in late summer 2011. To get there we're going to have to do some fundraising and lots of other planning, but we're working on it.

Hi Chris and Taylor,

Great work! I just figured out about your project a few months ago, so I decided to participate in the funding for version 2.0.
I like to ask if you are planning to make use of the RepRap PCB 1.5.3 version for driving the stepper motors? For more details, see: http://www.reprap.org/wiki/Ultimaker%27s_v1.5.3_PCB
It;s an Arduino Mega based controller with Polulu drivers and will work with Linux, Windows and Mac platforms.It;s a prooven concept and besides the RepRap also used in the very fast Ultimaker 3D-printer: http://blog.ultimaker.com/

Best regards,

Leon.

Now that our kickstarter campaign has [successfully!] ended, we're gearing up to do some serious R&D for the next version of the DIYLILCNC design.

We've got a lot of changes planned, so many that we've created a special forum for hashing out all the planned upgrades: http://diylilcnc.org/forum/forum/diylilcnc-v2

When do you think the v2 will be finished?

I'll be doing a solid month of design once my semester ends on December 15. I hope to have a working prototype by Jan 15, but the instructions and related material may follow at a lag. Would you be willing to purchase a panel set before the assembly instructions are finalized? This may also involve buying a kit that hasn't been fully tested, but that's what this project is all about!

As long as I know that the assembly instructions will be coming at some time for the case I run into serious problems and the shipping costs to Switzerland aren't as I horrendous as I think, why not?

But please specify "not full tested" more accurate, do you mean the individual kit hasn't been full tested or that there might be some design changes which haven't been fully tested and which could cause problems?

T4b,

The new design will address shipping cost by reducing part count as far as possible. This means you'll buy a higher percentage of materials locally (like metal stock, hardware, etc.). We'll also shift the entire BOM over to metric standards.

Once the design is complete, documentation will probably be released over time in blog-form. Last time we did a pdf, but that meant all the instructions got held up until we had the whole thing finished. This time we'll stick to an online format, meaning that we can dump a rough set early then come back through and add polished images and other support media.

As for "fully tested", the reality is that this kit gets nowhere near the quality control you'd find on the initial release of a more conventional product. That said, we get the same result over time by working with our users to identify and redesign problems. V2 is benefiting enormously from this approach, but you may still find minor problems if you buy early. We hope you'll see this risk in the context of our alternative approach to research and intellectual property. I can say that the device will essentially function fine, but you may have to use it to cut some mod panels as we do V2.01.

As long as I can use it to cut the modified panels it's no problem for me.

I guess I'll order the panel set as soon as it's available.

Could you maybe summarize what you've already done and what you still want to do to finish v2.00?
And what do you think when it will be finished?

I would build a v.1 instead of waiting, but I it would be a real pain to get those non-metric parts, I fear (probably with a lot of additional cost for shipping) and it would further increase cost to get a computer with a paralell port.

@T4b,

The core v2 design is complete, but we're still finishing up the documentation. See this link for details. I hope to release the rough draft by the end of the month.

We tested some USB alternate boards, but were unable to settle on a solution that can drive large motors. We'll look at doing a geared-axis secondary release that could play nice with existing USB solutions, but that's further down the line.
