The drawing of the spinning curves should be made in a special CAD setting and should meet somerequirements for SpinningCAD.2.1 The CAD setting: open CAD, draw a square area from the origin of coordinates 0,0 toward lower left(make sure to draw the square use [Line], cannot use [Rectangle]). The distance from 0,0 to the left is the machinetravel for Z Axis; the distance from 0,0 to lower is the machine travel for X Axis; And then draw a point at the 0,0.(for the convenience to find it, you can input “ddptype” in the CAD command to select the font style of the point,select in common .) The drawing of the spinning curve should be in this square area, otherwise, machine willrun exceeding the travel and give alarms.Set 4 new layers in CAD, the name and the color foreach layer are:FEED1,COLOR——BLACKFEED2,COLOR——REDFEED3,COLOR——BLUEFEED4,COLOR——GREEN
