Hi
I have a fiber laser and want to interface Mach3 to mark many small objects positioned on a large X/Y table , its not an X/Y plotter type but galvo based with a field frame size of 100 mm x 100mm so can only mark 1 object at a time.
I want to automate the process via MACH3  and load a table with objects and start the laser and sequentially mark and complete all  objects  in one pass.

The laser has an output pulse when the laser mark has finished and an input mark to start the laser .
what I would like to achieve is to have a macro that  starts the laser from an external pulse then when the laser has finished to move to the next G code , then when moved and stopped send a pulse to the input of MACH3 to start the laser and then repeat for the total objects on the table

has any one any ideas on how this can be done

please advise if further explanation is needed I can draw a timing diagram if needed

regards peter

art is come up with something like what you wont  for m4 it might work for m3 ask him on his Darwin post or he might see this
