Previously, I had posted about my OOZnest 1500x1500 going off the tool path course on the 5th or 6th pass and coming to a screeching halt in virgin wood territory. Several people suggested I reduce my feed rate which I have done and now is at 75ipm with a spindle speed of 16,000 RPM (the minimum on my Dewalt 611). I'm using a 1/4" compression end mill bit and taking off approx 0.119" each pass with a climb cut. I thought the culprit was an incorrectly hung dust extraction hose putting too much weight on one side of the router. I reconfigured my hose supports and all looked good for awhile. I got past the previous trouble areas on my tool path and several additional pieces were being cut without a problem until it got to the 7th piece where it once again went off course and cut through a previously cut piece (Image #2 & #3 attached). This piece is in the center of my CNC work area and should have the least stress on the hose, etc. I'm now wondering if there is another factor at play. The pieces that I'm trying to cut are very curvy (Image #1 attached) but in Vectric Cut2D pro, I specified bezier curves during the set up process. After the latest crash I opened up the sender settings in X-ProV3 (Image #4) and discovered some info regarding arc segments and thresholds. I'm wondering if I need to adjust these settings to keep the CNC on track. Anyone have any knowledge in this area? I don't have any idea of how the last two settings should be set. Someone also mentioned previously that I should consider using a conventional cut as climb cutting tends to grip into the piece being cut and my Nema 23 motors might not be able to keep the pulling from causing the CNC to go off track. The weird thing seems to be that the course deviations are occurring in the opposite direction of the material being cut! Any help you can provide would be greatly appreciated.
