Thanks.

Just so it's not taken out of context, my "toy" comment was aimed more at the hobbiest shop and not at anyone doing this for profit. How long ago was it that drum sanders were out of reach for most hobbyists and now there are several good sanders within reach of woodworkers that have the space and some discretionary funds. I hope someday that lasers will also fall into that category. What pricepoint are these at today?

While not being that familiar with the machines, I don't see that the hardware is all that complex. Is it not basically a plotter with a laser instead of a pen? Is the expense for these not tied up in the software to control them?

I'll be keeping my eye on this forum and look forward to seeing more unique and stunning pieces as you move forward.

Indeed, the software written to control such a system is pricy, but much of the
code for controlling servos is readily available, and the math has been
around since Newton invented calculus.

The price of the machine comes in with the servos and precision indexing, as well
as the laser itself. The laser tube itself is stationary, and is guided by means of a series
of precisely positioned mirrors and a translucent, moving laser head.
The hardware is incredibly complex--much more than an XY plotter.

With all of this in mind, however, I am certain they could bring down the
price of laser units significantly--once the complex software is written,
the programmers are paid and the release goes into maintenance mode,
which leaves the hardware to add to the price.
