I was rocking along and then halted. I tried to set chain lenght and get an image with chain outside of sprocket versus the inside. I did set chains with the outside sprocket but in ground control right is left and up is down. router moves in opposite direction of cursor.
When this first happened I went back to verson 1.25 and at chain was on inside of sprocket. Now even deleting 1.26 and re installing 125 i get chain on outside of sprocket.
