I have to cut & raster engrave a few samples for a client. What would the recommended S&P be on a 100w co2 in 3/16 Acrylic for cutting and for rastering a small logo/trademark in the corner? TIA Neville

Laser engraving cutting machine is little limited. It is good at for acrylic processing, when engraving, you could try fast speed, for cutting, maybe a bit slow.

80W could cut max. 15mm, 4mm or 5mm, 60W is ok.

You could try to test freely.

This was all done with 30 watts.
It's trial and error with the vector speed as it depends on material thickness as well as ambient temperature. Pretty much trial and error with the raster logo as well.

Do you have the dxf files for the three gears shown in the picture? I would love to try them on my CNC mill.

Sorry, I do not produce a DXF because I run GCode.
I have attached the GCode for 1 gear - see if you can do anything with it. Because these were laser cut there is no Z commands but in the code I use B0 to turn the laser off (Z plus movement) and B1 to turn it on (Z minus movement). Search and replace could change these to Z movement. The included tool radius offset is 0.05mm (laser beam radius) so you would need to adjust your offset accordingly also all my units are metric.
It's a long shot but if you can do anything with it then email me and I will send the GCode for the others.

Tweakie,

That's a really cool design!

I converted it to dxf and would love to cut the set and try it if you don't mind.

What program did you use to create these gears?

Thank You again. I scaled the original by 0.08 in AutoCad whitch brings the total set length down to just over 9 inches. I offset the tooth profile in CamBam by .004". CamBam generated the Gcode file for Mach3. The dificult part was getting the proper spacing to make them run smooth. They work very good.

Glad you got it sorted.

How about a ring for your next project. [nomedia="http://www.youtube.com/watch?v=939qJdnGLM8&feature=player_embedded"]YouTube - Gear Ring from Kinekt Design[/nomedia]

During F1 races they have adverts for this ring at every break. Very cool.

That would be neat, but it's a little beyound the capabilities of my JGRO maachine.
