Dear Tom,

Saw close topic, but not the same problem, so opened a new one.

I need to flatten the space for PCB engraving. I scan the physical PCB surface and fill the results to Geo Correction Table. The table's offset is set to 0. The machine's coords are also set to 0 when I apply the table and try to use it. It looks like only 1st cell of the grid is used and interpolated in all direction but not the entire table... I did one simple experiment: I set my surface as "V"-shape, with X=0, Y=0 at one of the egdes, while Z falls from 0 to -5mm, then rise up to 0 again. Then when I manually or by G-code drive the machine from one toward the other edge of "V", Z automatically goes down... and only down, despite the slop should go up again.

If you need more details, I'll give you. Perhaps I don't know somthing or there is real problem in geo correction?

Regards,
