Solution for Uneven Stone Engraving By CNC RouterMany cnc router users encounter this problem when engrave stone by cnc router. For tomb stone or other stone plate, why some position just touched by cnc router cutter, well some positions on stone are deeper engraved by cnc rotuer? This is related with the cnc router finding a blancing point on stone.
Before dispatching cnc wood router, manufacturers of cnc router will make working table even by cnc router milling cutter,so this is not the problem of cnc router table. Well, tomb stone or other stone must not so even, so if we make tool setting at left point, which is the highest point. This will cause some other position may can not be engraved. If this point is the lowest one, then may other position wil be keeper.
For avoding this problem, we suggest setting processing origin xy and z seperately. Still set xy at left down point of material, well, make z at the center of material, in this way, the whole engraving depth may is similar. If there is a big difference for different position material thickness, OMNI suggest make cnc router tool path to upper down two parts or upper, middle and down three parts. Or you use cnc router to measure the four edge point of material, according to X axis value to see which position is high, and which position is lower, then make some stuff under the material to keep the whole material even at most.
