Why does it happen when you are under pressure ?

The pieces are cut as two 'identical' interlocking spirals, so the gap is due to the tool width. The wood is 8mm thick so I had to use a tool with a long flute, and 2.2 was the smallest I had. The planks were 6" so the end size is 140x130 mm. The dxf was done with corel draw and is a bit steppy. and I had to do a lot of editing on the Gcode to get rid of redundant cuts. They are intended to be separate pieces to make two trivets if necessary. They were finished with a rub of sandpaper and teak oil.

The Gantry router was Made in Devon, so there were a number of runs that ended up as kindling.

If anyone wants the Gcode I'll post it.

Cheers,

Rob: Very nice and different I think that the gaps add to the design It would be nice to see the gcode or the dxf or even both. ..Clive
