Laser cutter?

Post by scubamatt41 » Mon May 13, 2013 3:13 pm

I hope to add a laser cutter to my toy collection. There are a lot of laser cutters out there which makes it a laser cut jungle :roll:
Can anybody guide me please? Initial spec's I try to meet are:

1. workspace: somewere between 400x400mm (15,74" x 15,74") and 600x600mm (23,62" x 23,64") or a varius combination of dim's. I hope I explain myself here?
2. cutting: plastic's, no glass but able to cut through max 2mm soft metal i.e. no stainless on high grade's
?..........Please feel free to fill in :)

Any help is welcome
Cheers, Matt

Hi Matt
I have a 50 watt laser engraver/cutter with a 500 X 300mm work area. You will need a much more powerful laser if you want to cut metal. The killer will be the cost of replacement laser tubes. I reckon you might be better using a CNC router. A nuch cheaper option. Having said that, my laser is great for cutting acrylic. I have cut up to 15mm thick acrylic. I also use it the engrave labels for a local business that requires regular supply and short lead time.
It pays for my other toys.
Regards
Lawrence

I got one of the cheap 40W eBay lasers. They're great value but you need to "fix" it when it arrives and I ditched the awful Moshidraw software / controller for a ChrisCircuits.com one. However, you need a larger build area so will need to spend a bit more.

As Lawrence said, cutting metal with a laser means you need to step up into the big bucks territory. Anything more than engraving anodised aluminium (i.e "unanodising" it) isn't cheap.

Hi and thanks so far,

I've seen the eBay cutters and also some of the reviews. Indeed those cutters need some checking and what not. I don't like the idea of tinkering on a laser cutter to be honest. Cutting through metal isn't a must, just a sort of extra. The wallet is still extra extra small :cry:

I've also seen the Epilog 24 mini (mini is just my thing ;) ) but no idea what the pricing is?
If it's the same as the Full spectrum lasers or in that range I'm afraid I have to do some tinkering on a eBay laser.

Cheers, Matt

Maybe I am just becoming cynical and jaded (or I was laready) but I think whiterock might be spam ... their posts look a lot like the "long con" spam we are seeing on our CNC forum.

Totally agree. Don't send any money, scubamatt, unless you're really sure.

Okay thanks to roller and juliadee for the warning. I also looked into the "long con", very interresting.

"The Players in the ConEdit

There are three key players in any long con: a victim, a con artist, and one or more associates.

The Mark: The intended victim of the con.
The Grifter: A practitioner of confidence tricks, or more informally, a con artist. A grifter may play many roles, and often creates multiple personas over their career.
The Shill: An accomplice to the grifter, who has no apparent connection to the con. Shills are put in place to encourage the mark to act in the desired way.

A long con is executed in one or two settings: a real world setting, or an empty room, known as a big store set up to look like a real world setting, such as a stock trading room. For a long con to work, it requires a team of grifters, which plays a variety of roles. Some players may be experts at one role, others can change them up as the con demands.

The Roper: The member of the crew who identifies the mark, and lures the mark in. The roper usually begins by finding a way to get close to the mark, insinuating himself into the mark's life. Slowly, he or she makes the con sound enticing by offering the mark what he seems to want, leading up to an introduction to the inside man. From there, the roper's job is to keep the mark interested. He or she may create the illusion they are a participant in whatever opportunity the con offers the mark. The roper is often an older man with the appearance of affluence or an enticing woman, who embodies what the mark aspires to: wealth and the attention of a beautiful woman.
The Inside Man: The crew member in charge, who executes the con.

The Fixer: Often works near, but not close, to The Inside Man, as back-up and coordinate resources as the con unfolds. This is probably the most versatile role in the con, and the person has to have a combination of skills, from Grifting to Hitting. Often this person will wear more than one alias during the con, so they need to be easy for the Mark to forget.
The Face: A shill, generally an attractive female used to distract or encourage the mark.
The Outside Man: This could be a potential threat (as a fake Law Enforcement Official) or a potential fake target for the Mark to exploit, to gain the Mark's confidence.
The Floater: A secondary Inside Man, who can work in conjunction on The Mark, or work a secondary angle on the same con."

according to wikkipedia

I just meant long con in the spam sense ... that is they post many vaguely valid posts so they get past manual moderation before bombing the site with a hundred spam posts... but yes, may also be a scammer.

On the laser front, as I think was mentioned, you will struggle with metal. It needs to be prepared with a paint or finish to make it absorb rather than reflect the laser. Typically you'd be looking at 100W (from memory) if you want to work with metal that thickness and can bare all the prep and cleanup. I always have to get my metal cut by waterjet or CNC. Glass presents similar issues though I know you said you weren't needing that.

About 40W is good for acrylic up to about 4mm though you will need to cut slow or multipass or gas assist I think to get a good cut and 60W should do it without fuss. Laser is a lot of fuss and hard to do/get on a budget. Can you possible live with a CNC instead i.e. noise, unable to do internal corners smaller than the bit/endmill radius. I built my 1200x600mm (4' x 2') for about $1000 and that's in Australia where everything is overpriced.

I'm positive whiterock is a spammer using forums like this to increase traffic to his website.
Here he asks if anyone knows where to get Drum Scales for under $500 and then has a link to a drum scale website on his signature!:

Shame some of the established members of this forum can't be made moderators to cut this kind of thing out - it's so annoying when you realise you've read these random posts, spent time trying to understand them and then realise you've wasted that effort on an idiot promoting his own crap

Most are fairly obvious too ... I presume the moderators aren't native English speakers.

I would like a laser cutter also.

QU-BD keeps on talking about selling them.

Seems like 200 watts for metal.

I have a plasma cutter that I could probably make CNC.

At least unless your only cutting foils and annoying prep to put a laser friendly surface on the metal to be cut so it doesn't just reflect all the light back up the laser path. Laser cutting metal is generally a pain.

I heard some good things about this one:

But, I do not own one so I can't vouch for it.
