Aligning tiled toolpaths

[mday]

Hello everyone, I am attempting my first tiled job and I cannot get my CNC to drill the alignment hole in the second tile (T2 drill).
I create the toolpath, preview it, save it, but my machine keeps cutting the T1 drill hole over and over, never moving to the position of the second hole.
On a piece of scrap, I cut both tiles measuring and drilling the second hole by hand. Naturally it doesn't line up accurately enough. The point of having a CNC is accuracy. I have attached the Varve file for reference. I guess I have to paste the gcode as plain text.

If you really want it to drill that hole there without tiling you need to uncheck the "Output Tiled Toolpaths" option and save the Drill toolpath. If the bed is that big though why tile it to start with? The hole is in the same place on both tiles relative to the tile start position which is why it looks like it's doing the same one over and over.

Ok I unchecked output tiled toolpaths and re-saved the drill toolpath. I will try it again.
The reason I am tiling in the first place is the workpiece is 54" long and my work surface is 48x48. I also considered running it at 45degrees, but I have the same issue with aligning the stock relative to the job. If I was cutting this out of a sheet, it wouldn't matter, but my stock is two pieces of teak that are not that much wider than the job so it has to be aligned carefully. Also I have to cut a 12 degree bevel on one edge of the finished piece at the table saw after it is carved on the CNC.

Unchecking "output tiled toolpaths" is the solution. Thank you. None of the tutorials I've watched/read ever mention this important little detail.

Ok now that I am done with that project, I would like tiled toolpaths to go away but they will not. Is there some way to stop the tiling tool manager from automatically launching and wanting to tile all my toolpaths? I have to manually uncheck tile toolpaths then hide the manager, on every project, then uncheck tile toolpaths when I save out my toolpaths.

If you click "Delete All Tiling Data" about halfway up the Tile manager form that should reset it.

Thank you!

Unfortunately the tile toolpaths box is still checked by default.
