Bought a 1 1/4 planning bit to level big areas. I have it cut in raster mode in vectric vcarve. When it travels in the x axis, the positive direction cuts fine, but the negative travel leaves burn marks. Any suggestions?
come up off the part and only cut in the direction it works well in
Or only cut in off set mode, then it will only be cutting in one direction.
If you are burning the work piece it’s possible that you have the feed rate to slow and it’s allowing heat to buildup instead of being carried away by the chips.
Check your spindle for square to the direction of travel. If its out of square it can cause the bit to drag on the back side of the cut
Reduce the RPM speed.
