tool path tiling

Post by cjablonski »

First time I've run up against the physical limits of the shark and it's capacity. I've reviewed the tool path tiling video from Vectric to see the work around. Was wondering if anyone here has utilized this and about how accurate it is from tile to tile. Anyone have any personal experience with it and any tips or thing I should know before I make sawdust?

Here were my two attempts, I think they came out well.

Tips are keep the overlap small, maybe .25 inch max. Make sure your slide along axis is accurate. Do a new Z-zero everytime you advance the board.

Good Luck!

Thanks a ton for the tips. Great work on the ruler BTW! :D

On everything I have done so far I have strategically planned the "tile division line" to be between two letter or the gap between words, so there wasn't any really need to match up within thousandths of an inch just within a 1/32 or so. I don't know what the accuracy is like otherwise but suspect it has a lot to do with your reference board that you slide along and how straight or "aligned" it is. You also need to make accurate and small reference marks on your material so that you can slide the work down an accurate measurement (ie length of tile).

What I think I may do to ensure the proper movement and alignment will be to create a sliding jig for the shark bed. Raised edges with through holes for clamping utilizing t nuts to ensure its square. May throw a rabbit or a dado on the edge to make sure the machining edges are dead zero to z axis. Additionally, if made as long rails, it would work crossways as an x/y zero point.

I use my scarf board (see http://www.cncsharktalk.com/viewtopic.p ... lit=+Super)

The pins keep the board straight in the Y axis. The grid is used to control the distance. The grid has all 1x1 inch blocks. So my tile was 20 inches. Simply put a pencil mark at one grid line then slide forward 20 lines.

Great idea. Will definitely incorporate that into the jig.
