I changed the orientation of the red oak so it cuts along the grain rather than across, but no change. I have tried various speeds and slowed the feed rate, but to no avail. It is only taking off 0.25 at a time and there is no issue going in the X+ direction or any other axis. It appears to only happen along the longer portions of the cut. When the 1/4" EM is moving along the toolpath I get an awful chatter/vibration in the X axis only in the X- direction. Now I am trying to figure out another issue. Setting the DOC to a lesser amount made a big difference. Thanks again to everyone on the advice with the roughing toolpath. Any help would be greatly appreciated as I am new to the CNC realm and have been diligently trying to learn as much as I can. I am sure the solution is staring me right in the face. I am using Aspire 11.016 and attached a visual of the project. I considered using the pocket toolpath to hog out most of the waste first, however, I would like to determine a more efficient path forward that does not involved running multiple toolpaths. I was wondering if anyone had insight on whether this is a feature, or whether I need to find another solution. My searched online have not yielded any results so far. Ideally I would like to take multiple passes to avoid this issue, but am having trouble identifying how to do so with the roughing toolpath. My settings were 12000RPM at 60IPM with red oak as the material. I selected a 1/4" EM for the roughing toolpath, but as it approached the full depth of cut (0.5") the machine sounded like it was under too much load. I wanted more of a slope to the sides for ease of retrieving stones and found the 45* or 60* dome/dish clipart to be ideal. My prototype involved 2" diameter pockets along the side and approximate 5x2" ovals at the respective ends. I am trying to find the correct avenue for creating some mancala boards.
