Re: Milling Glass

Hi all, this is my first post to this group. I have been following the
messeges for about a month now. Very informative. Thanks to Doug F.
for pointing me here.

John, your idea for using a sandblaster like a giant inkjet printer is
interesting. There is a link here
http://users.iafrica.com/r/ra/ralphm/scan2cnc.htm to some utilities. I
have not tried it but it seems that scan2cnc will porduce g-code that
moves the cutter in horizontal lines. This is a direct quote from the
page "The toolpath will replicate the printer file so it will be
raster cuts in the x direction with y axis step overs between cuts."
Maybe this could be adapted to you application.
I have allways wanted to put an artists airbrush on the z-axis and try
to airbrush t-shirts. I think you could vary line widths by moving the
airbrush up and down.

I have some info on home made cnc on my site for those who are
interested.
