Laser Butterfly

Post by citrusguy »

This is a butterfly I made for a Christmas present. I "cut" it with a laser diode using Cut2D and a customized post processor for Mach3.

I made it from 1/16 inch thick hobby bass wood. Due to the low power of my laser diode, I burned it from both sides of the wood using Cut2D's flip feature.

Happy Holidays All,
John Champlain

Thank you, friends. I would like to point out, however, that the design of the puzzle is not mine. Credit for the design goes to a member of the ArtSoft forum
( http://www.machsupport.com/forum/index. ... 111.0.html ). I only wish I were so talented.

Regards All,

John,

The fact that you can do two sided machining is an indicator that you know and understand your machine. (My first attempt at two sided machining was a disaster :oops: ) I look forward to seeing other projects that you will post as your skills continue to grow.

Turned out great, John!

BTW, what laser diode are you using?

Thank you guys. I appreciate the kind words and your encouragements.

Ron, I'm using a 445nm diode with my own design constant-current driver at about 1.1 amps. I think I could increase the power some, but at about $50 US per diode, and having already blown one diode while experimenting, I'm inclined to leave it alone for now.

I use a small blower to keep smoke from interrupting the laser beam, but at the suggestion of a poster in another forum, I will soon add a small compressed air jet to try to remove carbon from the kerf while burning.

I have also found that the laser is much less forgiving of backlash than when routing, so I will soon rework the Y axis to replace the present bronze bushings with linear ball bearings.

Happy New Year All,
John Champlain

My version of the Mayan calendar pales in comparison to Paul Rowntree's (http://www.vectric.com/forum/viewtopic.php?f=5&t=11586), but I'm pleased for a first try.

Burned into a scrap piece of MDF - about 7.25 inch diameter. Careful examination will show the backlash (friction or "sticktion" ?) in my Y axis that I mentioned earlier.
