Look my CNC with IR Laser

[Fred_DASP]

I put an IR Laser from CD Burner on my CNC.

I used DDL to drive the diode.

Questions?

that's awesome, makes me wanna try building something like that for myself

 

[Fred_DASP]

how long a diode can be turned on without heatsink?
This diode stay warm after 1 minute, it´s normal?

ahhahaa: no problem its your game  :
....but i think i want a replay

Lots of great mechanical noises. What power/current are you running the diode at, and what CNC is it?

 

[Fred_DASP]

drlava, I did this CNC on my vacation using Step motor from NIMA old printers and othes stuffs.
Normaly I use with a dremel (similar) to milling acrylics.
There ar others videos in my Youtube Channel.. take a look.

The diode runs at +/- 105 mA.

The power output of diode laser (no matter the color) is P=I*V as some ppl says ?
I don´t belive because there is some heat loss. Right?

This is amazing. You built your own CNC and decided to adapt this tech to make it do engraving. You sir, are a true "maker." As we say. My question is, where did you find the plans and software to drive your CNC? I would like as much material on this as possible.

I'm also in to CNC-building and everything you'll ever want to know about hardware, software and construction can be found at www.cnczone.com
There is even a special subforum for laser engravers and cutters!

 

[Fred_DASP]

I know this CNCZONE forum. Really great.
gn0stik, there will be much more happy than my explanations

The software is KCAM, w3.kellyware.com.

Fred, Did you buy the frame (XY table), or make it? I would like one of that quality, but unfortunately I do not have a welder, (or metal cutting band saw) so I would have to buy one (unless someone would allow me to pay them to build me one), I already have step motors that I could use from some old okidata dot matrix printers. I could have a table welded up locally if someone could direct me to some plans for one.

Thanks.

gn0stik: Sorry to answer you late. I saw this same question in CNCForum.
Well, this frame was done by a friend and i painted with a simple spray. nothig special.
Is true that have a good look. It´s a 20x20mm square 'metalon'

I asked to guy to do a 30x30 cm square with a 7cm of 'legs' and 25 cm to up from the square as you can see below:
