I've been having a lot of trouble recently with my cut going off path and I'm not sure what it could be. Usually it happens around a corner. It'll go 3 or 4 passes and then suddenly go off path, I think usually on the X axis (right to left). I've tried this cut 4 times with 1 success and 3 failures.
Things which I have checked:
- Spindle upgraded to Dewalt 611 as I was afraid the 24v spindle was having issues
- All belts are properly tight
- All v-wheels and properly tight on the maker rails
- Nothing seems shaky on the spindle mount or axes
- Material is properly clamped down
- There are no visible obstructions or knots visible that I can see - I am cutting 6mm MDF.
- I am using a spiral upcut bit, and have the router turned up to the higher side of its speed capability due to paranoia
- I am using default recommended feed and depth settings (1016 mm/min and 1.6 mm)
Below is a photo of the results, and here is my project file: http://easel.inventables.com/projects/yOSieDRKFbeIxQwuDvpnIA
Any idea what I might be doing wrong?
In the below photo (originally taken landscape) the spindle has gone off track on the bottom right (right upper side of the machine), while doing an outside cut of the hexagon, just after lifting near one of the holes briefly. I've noticed since there isn't much clearance between the hole and the edge, it seems to make little mini tabs there to keep them from tearing out.
