Mostly at the ends of the X. A little at Y. I am resurfacing my plenum right now. It looks to be cutting the whole table flat. Moving slow and taking off just a bit. When it's done I'm going to drop the Z .010 and run the same program again. I'll seal the plenum and attach the new spoil board tomorrow. Nothing really different then I've done many times, except I've never run the surface program twice in a row. We'll see??? Maybe I have been trying to remove too much at a time???
