When working with wavy material, the laser could become blocked by the material which will cause the machine to stop. Pressing the foot pedal again will mute the sensors and allow the bend to be completed in safe speed. If most of your bending is with wavy material, then you can manually increase the mute height to allow for the material height so you can bend without stopping.
On the HMI press MENU > SUPERVISOR MENU then enter your supervisor access code. Use the arrow buttons to navigate to MUTE OFF-SET DISTANCE then press ENTER. You can then adjust to the desired height. Press ENTER to save then exit the menu. Be aware that the monitored speed change point will increase according to the increased mute off-set distance, so on some machines you may also need to increase the speed change value in the CNC. Refer to the Operator Manual under the Manuals & Guides tab for more details.
