V 29 oem post

I am looking to add on a laser to my cnc router . I see that many people use the spindle feed to turn on / off laser , but how do I turn it off during rapid moves between tool paths , so it does not mark the piece ??

Thanks

Well, I don`t know much about laser cutters so I just had a look at the BC Laser PP and it looks like the On/Off and Z retract for rapid moves seems to be done automatically with the following areas in the PP,

50. Line rapid move Z - Z retract
" "
n,lpw_cutter_off
n,lpw_gas_assist_off
n,lpw_shutter_closed
" "

51. Line feed move Z
" "
output_part_number
n,"( MSG,PIERCE ",shape_number," " In between these quotes it should have a colon : and a bracket ) but the Zone is putting a smiley in there !!
" "
n,lpw_shutter_open_closed
n,lpw_gas_assist_type
n,lpw_gas_assist_on_off
n,lpw_cutter_on_off
n,dwell

750. Laser-Plasma-Waterjet Cutter Width Prefix? "D"
751. Laser-Plasma-Waterjet Pierce Height Z Location Prefix? "Z"
752. Laser-Plasma-Waterjet Cutter On Code? "M702"
753. Laser-Plasma-Waterjet Cutter Off Code? "M703"
760. Laser-Plasma Gas Assist On? "M710"
761. Laser-Plasma Gas Assist Off? "M711"
762. Laser-Plasma Gas Assist With Air? "M712"
763. Laser-Plasma Gas Assist With Oxygen? "M713"
764. Laser-Plasma Gas Assist With Oxyacetylene? "M714"
765. Laser-Plasma Shutter Open? "M715"

767. Laser-Plasma Pulse Frequency Prefix? "F"
768. Laser-Plasma Power Setting Prefix? "P"
769. Laser-Plasma Torch Height Control Prefix? "T"

it may be of some help to you but if you haven`t already got one you will need to download a Laser PP from BC to suit your machine control, I have Zipped up the one I have here for you to test, it is for all versions V26 through V31 so should work!!
