Howdy.

For a while I have been wanting my own laser cutter for rapid prototyping stuff at home. Normally they are the prices of a new car, and the cheap Chinese ones are a bit crappy.

I have access to a £16k Epilog for production runs (I design robots - www.botbuilder.co.uk), but using this for prototyping eats up time and money.

So I find on the bay one starting at 99p. Advertised as running but not working with any software. I have built my own CNC machines in the past, so not daunted by this. Yup it is a Chinese one, so probably a bit shoddy, but it has a sweet USB control board. Most of these come with horrid controllers and software that is not ideal for my uses, so I have avoided them in the past.

I won it for £230, went to pick it up and bought home this:

(Car is a Tamiya Mad Bull for scale)

Sure enough it fired up and I could move the X/Y axis, and fire the laser. Sweet!

After 2 days of debugging, I have it working directly from CorelDraw, as if it was a printer. It detects different coloured lines and lets you set speeds and powers etc. It will also engrave vectors and bitmaps!

So one all the comms were sorted, I took it all apart, as these things are assembled badly. No 2 bolts were the same and lots were missing!

They are all the component parts, at least the controllers and X/Y table were relay good quality. The c02 laser tube is at the front.

While it was in bits, it got a paint job as the factory colours are horrid.

Finished in gloss white and gun metal, with some nice warning labels cut on my vinyl cutter.

I put it back together with all new bolts and locking nuts. Nice and sturdy.

I really wanted a honeycomb bed, as this had a clamp, and not ideal for my cutting needs. Honeycomb is expensive, around £200 sqmtr. I Googled and put a call in to a UK factory. Asked for any off cuts, and next day I had a Jiffy bag containing a cut piece to size FOC! This stuff normally is used in missile fins!

Next I had to remodel my tiny workshop to get it in. New worktops cabinets etc were added.

It also needs air extraction to the outside along with a water pump to cool the laser.

Not done a lot actually using it, but for aligning the mirrors and focusing the head I have cut a few things out:

The smallest hole on the rocket is 1.3mm

So there we have a £4k laser for £230 and a few days hard work.

Hacktastic!

BTW It is a 40Watt (That is Watts of power not Milliwatts as you get on the laser diodes. This is a C02 laser and yup I have already burnt my self using it)
 
That's so cool. I look at threads like this and think of the skills needed to do what you've just described and I'm in awe. What else are you planning to cut with it?
 
Indeed, I can't stop playing with it. I did that rocket in about 5 mins. Quick design, then output to Mr Laser, It is like a printer on steroids!
 
Gotta say mate, that seems like absolute steal.

Just shows that not being afraid to do things yourself can lead to great results

what's that mean? :o

oh a side note, all round pinter's in the case of a zombie/robot apocalypse :p
 
You sir, have some skills, TEACH ME

Nah I just hack stuff. I ain't scared of technology, but invisible lasers that will burn your retina in nanoseconds do. When I was aligning the mirrors, I hit the pulse button with my hand still in there. It was only on 10% power but my skin vapourised! No bleeding as it cauterises as it cuts.

If you want to know what a co2 laser is like, Wikipedia a class 4 laser. Whoo.

picks of laser charred hands :o
 
I didn't understand half the technical stuff in that post but damn this looks awesome. You've found yourself a bargain, I wish had some (any!) skills like this...
