I'm in the middle of building a new 4x4 CNC Router I bought. I'm mainly going to be doing wood projects but of course I had the idea I could use it to make some Coro props I have in mind. Has any cut Coro with a CNC? I was wondering what type of bit I would use.


Thanks,
Gil

David Moore of holidaycoro.com has built a business around using his CNC for creating elements using coro

Yeah I'd love to hear how he does the cuts. I promise I'm not planning on making a business out of it. :)


The main thing I want to try to design and cut is a big 3d star to go high on the roof to be seen from all directions. I'm thinking of something with a lot of points like I used to see hanging on porches. I googled and found they are called Moravian stars. I thought it would be cool to have one like four feet tall and each star spike could be controllable to a different color.

From the cnc machines I have seen on youtube cutting coro they use a cutting blade not a rotating tip. So basically it's still like use a razor blade but letting the machine hold it instead of a hand.

Do you mean something like this???
http://www.moravianstars.com/videos.htm

Those would be one hell of a construction but would look amazing, good luck with that :)

I'm sure David Moore uses a router bit (cutter) of some sort as you can hear it running in his demo videos.

I would suggest a "LH spiral" or "down cut spiral" to push the corro onto the machine bed as opposed to it trying to lift it up (with a RH spiral) or push it away with a straight fluted cutter.

Thanks for the suggestions. I couldn't find David's videos but I did stumble onto this video which looks like the way I want to do it. It also confirmed that I really want to buy the Aspire software.
Cutting Vinyl and Coroplast with a Donek Drag Knife

I think I will start with something simpler than that 26 point star design. Maybe use it to cutout Shell's snowpeople. :)

Hi Gil,

Have you got any links to the Router you bought? I have looked into this before but am curious as to what you bought

Cheers, Coxie

Gil, you might be my new best buddy! Need pics of the CNC router of course too. I would think a 3/16" or even 1/8" spiral compression bit would work fine. Depending on how many pieces you were going to do. I was considering making a drawing or two and bolting a few sheets of coro together and visiting the local water jet cutter. Get an slow week run when they don't have a full schedule.

I bought this CNC kit...it's the 4x4 PRO version:
http://www.cncrouterparts.com/pro4848-4-x-4-cnc-router-kit-p-251.html

After adding a stand, the Nema 34 electronics enclosure, and other accessories the bill was above $7700. But I had just finally sold my old house that had been on the market 2.5 years so I burned some of the proceeds on this since I've always wanted one. Now the problem is I really want to buy the Aspire software package but it's near $2000.

I'm near done building it and just took a couple photos last night but didn't get a chance to offload the photos from the iPad.

Looks superb Gil, very envious :) I wish I had the room at home (and resources) for such a toy. Looking forward to seeing what you can create once all up and running.

Be sure to keep the pics and updates coming. Cheers Coxie
