The X/Y offset is adjusted. 5.1 Determination camera-to-milling head fails In some cases, it is possible that the drilled hole could not be measured and the determination procedure will be interrupted. Fig. 9: Alignment Fixing the determination failure 1. The determination camera to milling head fails. The following window is shown: 2. Open window Processing and use [ ], [ ], [ ] and [ ] to move the mill/drill head into the position of the drilled hole. The drilled hole must be displayed in the centre of the camera view. 3. Click [Find and Center]. The drill hole position will be measured and the drilled hole is centered in the camera view. The determination procedure is running and the result will be displayed. 4. Click [OK]. The dialog box Save results to machine is shown. 5. Click [Save] to save the data into the machine controller. The determination was successful LPKF AG HB V1.0/Sep-12 11
