Thanks Normand
You are correct about the mounting. I mounted the scanner on the z, but it could be mounted on the y carriage and moved in the x axis.
The actual scan took about 15 seconds at 2 ips.
On my slow computer (450 MHZ), processing the scan image takes about 90 seconds. About another 2-3 minutes to trim up the image to the desired elevation/width etc, and create the output files.
Thanks again.
Tom.
