thats amazing,.its almost a small cnc ( i know it actually is) that you could use for normal woodworking. it would be great for inlays etc or general carving.
i presum the patern on the board is allowing th ecomputer to triangulate the position 
imagine what will  be here in a few years time.

what would happen if you shoved it too far.

Jesus that is amazing! If they could take it a step further whee all you do is place it where it needs to start and they have some kind of ball bearings on the bottom then it makes it way around the sheet by its self just like a Cnc can do.

If you shove it to far it goes off line. The router user does have to keep it within 1/4" of the line either side.

Still, it seems faster than making a template and definitely better than free handing an inlay where I have to stay within a 1/64" of the line for inlay work.

That is really cool.  GO MIT!  I watched the video 3 times before I read the article because I thought the guy was my younger brother with longer hair. Scared  I guess the future of guide rails and TS saws does have a different future.

The tools in my truck were talking the other day.  The Dewalts, PC's, Boschs, Makitas were not happy.  They also were in the minority.  Their complaint:  They felt unused and unappreciated since the Festools moved in.  I guess the truth hurts.

I was thinking the same, however, on an inlay you definitely have a small size of blank (even if you use the laminate shell, it's only 5" x 9", so with a CNC machine it can "hover" over the blank which sits on the table, but here you'd have to come up some sort of inlay table that lets the blank sit flush with the rest of the bearing surface.

Still... a cool way to make CNC for inlay and templates affordable to the small hobbyist!

I saw this earlier today and was thinking this seemed like a concept that Festool could/would implement. The 'base' could be used across a number of different routers. Anyone else watching the video think that operation, while cool, looked really messy without having the dust collection we are all accustomed to?

Well the inlays I do are a little different, not for guitars, but furniture and floors and they are huge.

If they could get this more accurate(they will this is the first attempt) who would need a track anymore. I  envision snapping or drawing a line with a special ink and just pushing the saw and it follow the line exactly. Same for a jig saw. Mark the path with a special pencil and the saw just stays with the line. I think if that 1/4" could be a 1/64" or less it could work. I know with my CNC everything is within .001, so its feasible they could get that accuracy and precision with this type system in the future.

This reminds me of what some envision for the roads of the future where car accidents a thing of the past and the car just stays in the proper lanes with very little input from the driver.

Maybe I have to re-read, but I think the user is just responsible for keeping the tool within 1/4 inch of the guide line. That's as much correction range as the unit has. The accuracy to the 'plan' is better than quarter inch.

The tape is used because the unit also has to be able to tell how quickly the router is being moved, not just the direction. It has to keep track of the coordinates  You could accomplish the same thing with a perfect criss-cross matrix of perpendicular lines, but if there were any error, the output wouldn't be accurate. The tape has a pre-determined pattern on it that the software can measure to get both speed and direction. It's really clever.

Yes you are correct the user only keep it within a 1/4" of the line.  Smiley I had a brain fart, I actually knew that.   Smiley

I wonde long it takes to lay out all that tape correctly? Maybe in the next version they won't need the tape. Just position the router on the sheet then follow the pattern on screen. That would be really cool.

What would be cool you buy this special paper with all the lines on it for it to work  you just stick it into your  normal home printer and print a black outline of what your want the CNC to cut out and stick it to your wood either with special one side sticky paper or some low tack glue..  

This cool cnc would recognise this outline being different to the rest of the paper and fallow it perfectly for you.  You can then easily make anything you want then.  You can join paper together as long as the lines meet up so you can do larger cut out or if you own a larger printer can print on larger paper.

I think its a brilliant invention can see it being really good for on the job work or small workshop.  

I cant see it being used for anything more than inlay  because even if it had the power to move a large cutter across it would most likely pull your arm about instead and so would loose its accuracy

Here is another similar type technology except it allows the user to work freehand! It's called Free D
