Has anyone ever made the motors on the sled? how to deal with extra chain?

The concept and springs of this blinds rollers would do the job on taking the chains. A new and larger housing would need to be made.

The sled was build around a Lazy Susan I think. The first triangular before we had it in the software.

## My Maslow is up and running!

This is a photo of my first g-code run using a sharpie for a router bit.  Hey!  I don't wanna waste wood while I'm tweaking things, right?  https://imagebin.ca/v/3H5RMCHXBJAc



My machine looks a lot different from Bar's and so a little explanation might be in order.  Before Bar sent out the beta test kits I had already started hacking on the design.  I'm like that, ok?  https://imagebin.ca/v/3H5Rnz6K52xC



First off, I wanted my machine to be totally independent from the frame so that I could take the router, sled, electronics, and motors off the frame and pack them away in a reasonably sized package.  I wanted something that I could put in checked luggage or ship via UPS.  The reason for this is that I would like to be able to take the Maslow with me the next time I take a mission trip.  The last time I went somewhere (Haiti, after the earthquake) it would have been wonderful to have a tool like Maslow to help with the relief efforts.  Having everything together on the sled makes this a possibility.



Another reason I redesigned the sled was because I spend about 11 month s of the year traveling around the US in a big 'ol motor home.  I'm working as a traveling emergency room nurse and I take short-term contracts at hospitals around the country.  As such, I don't have a garage or much space to spread out while I'm on the road.  Having the Maslow reduced to a smaller, portable package just makes it easier for me to play with it when I'm away from home.



I also wanted to change the geometry of the machine to bring the math back to a simple trig function.  I was worried that the original design allowed for some unwanted torques since the router descends below the focal point of the chain triangle.  Now, to his credit, Bar has implemented some amazing black magic code to overcome this issue.  I was just hoping that if I went back to a basic triangle I could increase the cut rate without sacrificing precision.  In order to accomplish this I used two 12 inch diameter circular bearing races (http://www.rockler.com/low-profile-lazy-susans) mounted so they were each centered on the router bit.  I mounted the motors to these, each to its own bearing.  This setup allows each motor to swing around the router bit independent of the other motor.  It still remains to be seen it this will work or was just a lot of effort for minimal benefit.
