from the video we can see while working, there are only 3 axis with movement.It is : Rotary, Y axis and Z axis.
When the rotary is working. The X axis Driver is connected with Rotary Motor instead of X axis. So there will be no movement of X axis motor. So it is not a fault if rotary is running and X axis keep still.
Since there is no movement on X axis, the 3 axis type cnc router only can do regular cylinder engraving.If we want to do complicated cyliner engraving such as with flat 3d engraving then we need to use 4 axis rotary cnc router.
