Long sign

[Ralph]

Trying to find information to make a sign longer than the machine bed. I have designed a sign 28” x 72”. Machine width will accommodate the x dimension. Y dimension needs to be milled  One long board in two segments. How do you set up the file to mill and relocate the work piece for the second run.  I’m certain there is a tutorial on this but it seems to be lost to me. Any direction would help.  I have an older pro 8 CNC. Thanks

If you're using Vcarve, then you use the Toolpath Tiling option. Toolpath Tiling

I'm making a piece of furniture for myself and was about to register and re-register a part that exceeds the 36" length of the machine. I was thinking about it as I drifted off to sleep the other night and a better solution came to me in a dream: 


I'm guessing that 53" is the max you could get along the diagonal with a 24" x 48" machine, tho.
My plan for milling along the Y-axis would have involved 4 1/8" pins, but I would be coming up with a tiling strategy on my own (if RhinoCAM has a tiling feature, I haven't used it)

I did this by using the tiling option in VCarve. So my design on a 2'x2' bed was 2'x4'. I clamped a board to the bed to register the X axis. Then after the first cut, I only had to slide the workpiece up Y and X was fixed in place. I used a roller stand to support the off bed piece so it wouldn't put too much strain on the clamps/bed and potentially distort the Vcarve.

After the Vcarve on the top half, I made a very shallow pair of registration marks using a fluting path at the lower limit of the 2x2 workpiece. I slid the workpiece up Y until these registration marks aligned with the top of the frame and kept going. Letters/images lined right up and I sanded out the registration marks in the final piece.

I have also cut smaller puzzle pieces and then glued them to a backer support board. With a little creative filling and sanding, the gaps disappear and you have unlimited capacity...well, within budget <g>

Good luck!
