JT, you're welcome and thanks for the kind words. I am just glad you had a back-up piece of marble. So many of my items are one of a kind, I guess that's why I had to figure out this machine and software.
You can resize the template and it will still work, providing you do both front and back to the same size.
Here's some more tips to keep in mind:
Don't forget to clean the lens (both sides) and mirrors once in a while. A q-tip and a little >80% isopropanol will do the trick, but don't rub at them just use a gentle wipe in one direction and let the IPA evaporate off. If you get a marble chip on there, or any other residue it will heat up and damage or crack the lens/mirror.
Monitor the water temp on long jobs, I use a cheap aquarium alarm. It may or may not be an issue for you, I'm in Texas and my evaporative 'chiller' can't always keep it cool enough.
If you haven't already installed a coolant flow switch I highly recommend it, and wire it to the laser enable circuit so if the flow drops the laser is turned off. This is cheap protection against the even cheaper water pump failing.
Zax.
