Thats very cool, Thanks!

1. does the fact the the gantry moves to and fro make the focusing any harder?

2. how far can the laser be from the focusing beem to cut?

3. can you engrave with this kind of laser

4. if so, how far can you be from the focuser to engrave.

5. sorry to be a pest!

1- Yes it makes it very hard to adjust but their really is no choice for the given set-up.

2- I can cut 1/2" no problem any thicker the beam won't go all the way through. My FL is 2.5 inch.

3- Yes you can engrave no problem, I have not tried that yet.

4- as far as I know you just modulate the frequency of the beam not the FL of it.

5- No problem

Paul,

What criteria did you use choosing your drive system?
What gear ratio did you use?
Thank you,
George.

[cncadmin]

Just speed and resolution running a 1/8th step and a 7.1 ratio. Got all my gears here- https://www.sdp-si.com

Could you post a List of materials and any other info that would assist others in re-creating this masterpiece. I would love to build one for myself.

HELLO
How many finishing size is your LASER machine? 24*48?
How many US dollar USD is the price?

[cncadmin]

My laser has a cut-able area of 28" x 60" and cost me about $2,500.00 +/- $250.00 all done up soup to nuts.

[hkxy]

2,500 is the price which the cost sells?

(www.Emissiontechnologies.Com) is your network?

[cncadmin]

I designed and built it myself the one from Emissiontechnologies is not in the same class as mine. My laser is faster and more robust than his and half the cost.

[ynneb]

Just wondering....... Why does the laser tube need to be glass? Couldnt it be made out of other non conductive materials? wouldn that make it more robust and easier to make?

Also, if you make the inside diameter of the tube larger, does that mean you get more power?

[miljnor]

I'm not a math major (anymore ) but half the cost? his table is 50watts yours is 100watts isn't it? and his is selling at a wopping 11999.00 and you put your together for under 3k, thats less than half isn't it?????

[miljnor]

Not to be a PITA but 11999 lets round 12k/3k is 25% isn't it?

[cncadmin]

Half the cost would be 5,999.50 so mine would be more than half the cost 75%. 12,000.00 - 75% = 3,000.00.

[miljnor]

you lost me man. I had thought your machine cost about 3k to build all total? is this wrong? (minus labor of course )

Hope not because I was thinking this would be my next project!

[cncadmin]

Yes it cost me around 3,000.00 and I was comparing the cost to the one from emissions technology that sells for 12,000.00 and saying that my machine was half the cost which in reality is 75% LESS than the one he is selling. My head hurts....

here some up to date pictures

sweet dude! almost looks like you rebuilt the whole thing since the last pictures!

I will definitely be pestering you when I get ready to do this!

Fair warning! :P

Not really I just redesigned the laser cutting head, that main mechanics I did not change. I added a 80/20 frame and plexi glass to help with smoke extraction. Art from Mach is help me out with getting the code right in Mach for use with lasers, all most there.... It's working so well right now and I'm learning something new, now the fun of logging what feed and power all the different material needs. The next thing I want to try is engraving.

Ditto.

Suddenly you have a small laser on the gantry. Where is the large laser tube that was sitting on the side? Have you changed lasers?

[JFettig]

Paul, how fast do you get that thing cutting and moving? its looking like a pretty sweet setup.

it appears you have to set the z height manually with that nob? how high above the work do you set that?

The machine will move 600 IM I depending on the material I cut a average of 200 IM. Their is no "Z" the adjustment is for adjusting the depth of field, the height is determined by the material and the thickness of what I'm cutting.
