I thought I would share a few pics of what I made of the little A3. All that remains is the X and Y carriages and a 3 axis Mana board! First it became a large format diode engrave It's now a 50W CO2 laser with a 1000mm x 650mm cutting area.
Water cooling and air assist added. Just about to upgrade driver boards to drive each Y motor from its own driver and run from 24 volts
This is now a really great tool.
