Hi,
with Autoleveller you present a Gcode job for the PCB. Autoleveller inspects the Gcode file to determine the
extents of the machined area and then proposes a Gcode file to probe the enclosed surface area in a rectangular
pattern. You might specify that you want probe points no more than 5mm apart so it will generate a Gcode file
that will drive a probe in that pattern and record the results.
I imagine if you present a Gcode file but instead of PCB tracks letters to be engraved then Autoleveller will
happily determine the extent of the letters to be machined and generate a probe file automatically.
I rather doubt you need an expensive probe. I would have thought a small button type switch with a stem on in that
you could mount in your spindle. If you glued a short extension onto the button and had the two wires from the
button terminals to your BoB that would be enough. Is precision beyond 0.1mm-0.2mm required? Thus you could
make a probe for under $5.
If you use AutolvellerAE the data produced by all the probe points is put into a file which gives a colour rendering
of the surface. Thereafter Autoleveller will take your original engraving file and modify the Z cut depth to match the
surface contour. That modified or corrected file is the one you use to cut the letters.
