General Mach Discussion / Re: I Need a macro written will pay.

Thomas,
the plan/experiment is to be able to take lasers output and replace the z axis position in the digitizing program.
You would zero the X&Y as usual through mach on the servos, but z would just be there as a bracket to hold the laser it does not move,apart from initial set up to zero the laser.
The laser would be zeroed on the bed of the machine or another conveniant known point, that could also be the highest or lowest point on the job to be scanned.
obviosly if you zero the laser on the bed or lowest point you would zero close to its maximum sensing distance, and vice versa.
So if you put a say 25mm block under the laser it would read +25mm on the output of the laser, and so on.
You would run a digitizing program very similar to and possibly based on arts program, but instead of the z axis going up and down "probing" at every step,
the laser would be triggered or read at each x-y position and then that figure would be put into
the digitizing points cloud file as the z cordinate.
This would increase the scanning speed immensly but still retain high accuracy.
Hope that makes sense ?
Regards
Tony
Thanks again for your help
