Back into glass etching
Posted: Mon Oct 10, 2016 7:52 pm
Hello all,
I've been upgrading my K40 set up and with my new 600w (lightobject.com) chiller I am able to run all night, well until I run out of beer...
My latest is 'ol glory' done in glass. I have 3 layers, each layer is a different color. The original graphic came from a vector graphics site (purchased) and I used Illustrator CC to work the image so LaserCad can work with it. I save the Illustrator file in a version 8 copy which imports well into LaserCad.
Once in LaserCad, I can set which objects get engraved for each run and with the stock window panes, I am running at 11% power at 100m/sec speed.
The LEDS are silicone glued to the side of the glass and I will be using the TLC-4950 PWM chips to drive the LEDS. With PWM control I have the ability to sequence the LEDs and PWM also gives a power control to help extend the life of the LEDs as I can set intensity levels.
Attached are pics of the current progress. I hope to have the LED drive finished this weekend but you can see where this is going. The sample images only have one LED per layer engaged just for a quick preview.
I'll follow up once the LED drive is complete.
