~US$360 is a good price. Looking for the equivalent here in the UK... it's more then twice the price. :(

http://www.ebay.co.uk/itm/201458398614

£369.99 (US$564.01) for the laser + £134.66 (US$205.28) for postage.

Damn.

So what mods are folks doing?

Here what I am adding to start with :

- Air assist nozzle from lightobject - I am going to try with an aquarium bubbler first to see if it's enough but will probably get an airbrush compressor
- 6 inch inline fan with ducting
- new fan mount (this one is supposed to fit perfectly http://www.amazon.com/gp/product/B003NE ... ge_o00_s00 I'll let you know if it does)
- Temp sensor for the water

- Looking for a flow meter something that will light a light/ shut off the laser if the water is not moving...
- Bigger water pump maybe we'll see how the one that comes with it works
- maybe upgrade the electronics, that is another see how it works

Pretty much all of the above.

Air assist nozzle will be made on my lathe.

Bought a HF air brush compressor for $55

Bought this 4" inline blower. I had already installed a 4" duct hose to outside vent.

Temp sensor I bought with alarm

Haven't bought a flow meter but looking at getting the one from lightobjects, around $10

Bigger water pump that is similar to this one that my brother had extra laying around. Free

Biggest upgrade will be a 31"x47" linear rails mounted on 80/20 extrusion. High performance CMC brushless servo motors and Applied Motion drivers. I have all that in my "junk pile" of linear motion parts. Just have to put it together this winter.

I am with both of you guys in the mods. I purchased the light object air assist and using an aquarium pump for now going to connect it to my standard air compressor. I purchased a cheap bathroom exhaust fan to use for my air extractor. It's about 50 CFM.
JIMF I am jealous that you are able to make a bigger bed for your laser. That will be on my to do list when this laser tube dies and I need to purchase a new one which will be a lot higher in wattage.

I found it for £371 + £6 shipping on eBay, but the moment I asked a question about it, they responded and offered to sell it to me for £340 off-eBay, including shipping. That is against eBay rules, but my understanding is that, as a buyer, I lose the protection offered by eBay, but otherwise I'm not doing anything wrong. I offered £320 and requested a VAT invoice, and they accepted. I paid, and now I'm waiting to see whether I get anything. :)

Here's a mock up of the larger laser frame. The Y linear rails are a pair of 31" IKO, the X is a 47" THK HSR15. The rail on top of the pic is a 55" THK SR20. I may use that for the X but will have to buy a longer extrusion, undecided about that.

These are the brushless servos and drivers I will be using.

Buying a K40 was to kickstart this project that I wanted to do for so long. When the 40watt tube dies, my brother said he will buy the new 100watt and power supply.

Yeah my plan is to play with this I have about 500 in it right now with all the extras. I want to figure out how the electronics work, I would love to make a module or figure out how to make it show up like a printer from illustrator or make it work with vCarve/Mach 3 (there are some tutorials out there). But we'll see. If the software works well enough and I don't have to fight with it too much I might get the 1500$ 50W version to get the bigger area (http://www.ebay.com/itm/50W-CO2-USB-Las ... SwPcVVt3BE) There have been a few good reviews on it.

Other mod if forgot was I am going to add a laser pointer like this --> http://www.thingiverse.com/thing:53301 seems to be the easiest.
