Well... I messed around with the tramming and got a 16" x 16" area pretty flat in both directions... then I went to surface the whole board. The area to the right of the red line is flat. The area to the left of the line has ridges... I ran my surfacing tool path primarily in the x axis (perpendicular to the red line) see pics below. Any ideas... I dropped the speed down on the spindle to 11000 rpms and 150 IPM... maybe still too fast?
Machine is definitely out of level. Ran first pass at .06" and it cut the whole sheet. I have an aluminum frame and the sheet was held down by vacuum. flipped it over and glued the top sheet down to the plenum board. I surfaced that at .03" and I had a low spot as designated by the red semicircle. Not worried about that as much as I'm worried about the ridges... any thoughts...
