Not too long ago, I bought a small "K40" laser cutter/engraver. Once I got it set up, I quickly discovered that while I really liked having the capability in my shop, I was extremely limited by its working size, which is only about 12" x 8".

So I started shopping around for a larger format machine. I was pretty much instantly overwhelmed- There were HUNDREDS of models available from dozens of manufacturers. Prices ranged from $1500, to the cost of my house... Where to begin?

The first thing I decided on, even before budget, was size. While there are a lot of models out there, there are really only a few standard sizes. Initially, I was looking at either a 20" x 28" or a 24" x 36" model, and I decided that the larger size would fit my needs better. Then it was on to research what was available.

On Ebay, you can get this size machine for about $3500, delivered, with an 80w tube (more likely 65-70 watts in reality). You'll need to add a chiller to that, which runs about $500. They look like decent machines, but the EBay sellers aren't really laser 'people', just importers in general, so there is little to no support after the sale.

There are a few US companies that have lasers built to their specifications, and then resell them here in the U.S.

One such company is boss laser. Their machine in this size runs roughly $13,000. A huge jump- BUT it is a better built machine, and it has the advantage of US based customer support. As much as I liked these machines, they were just out of budget. This is a hobby, after all.

There are, of course, other US options, including those that are made in the USA, however these machines are MUCH more expensive- some cost more than my house! I'm sure you get a great machine and excellent support, but since I'm not running a business with it, I can't justify that kind of expense.

So I started looking in to having a laser machine built to my specifications, and imported. It turns out that this is the most cost effective option, though it does involve more risk on my side. After doing a TON of research, I finally settled on a machine, and ordered it. The order just went in- So for the benefit of others out there that might be thinking about doing the same, I am going to start this thread to document my new 'toy', and everything that is involved in ordering it, having it delivered, and getting it going.

I'm no expert at this- I'll be learning along with you! :)

First of all, "Meet" my new Machine-

attachment.php


It is being built by a company called ZingCNC (http://www.zingcnclaser.com/)

Here are the specs-

900mm x 600mm working area (Just under 36" x 24")
RECI W-4 Laser Tube (100W with a 130W max)
RUIDA RDC6445G Controller
Rotary attachment
Motorized Bed Table
Pass through
CW-5200 Chiller

This package, delivered to my nearest port (in my case Atlanta), was about $3200. I will have to pay import duties on it as well.

Compare that to the Boss, At $13k plus shipping. All other specs are virtually identical.

The transaction is being handled through Alibaba, who handles all the money and the 'business' side of things. This adds a layer of protection when dealing with a Chinese company.

It will take 10 days or so to build, then 4-6 weeks to ship.

I organized a group of 7 people on here a few years ago to do a group purchase of in-ground and ground-Mount scissor lifts a few years ago. The hardest part of the whole thing was finding a freight forwarder and customs agent at the US port to handle the paperwork, most of them only wanted to work with me if I was a business.

Make sure you have this part handled. I can dig through my email to find the guy’s name and number if you need it.

So, How did I decide on this model, and this company? Research.

There are MANY suppliers of machines like this on Alibaba- Several dozen. I started contacting them, and getting quotes. Luckily for me, there was someone in one of the FaceBook groups that I belong to that was looking for almost the same machine that I was- and he did a lot of the 'legwork' for me, and shared the information. He compared over 20 different manufacturers, and put together a list of the ones he considered 'best' based on the quotes and his interaction with them. I then contacted a few of the top choices.

Going over the details of the quotes that were provided, I singled this one out as being the best overall 'deal'. It wasn't the cheapest option, however it seemed to offer the most bang for the buck. It was a combination of my interactions with the sales people (who were very knowledgable), and the final specs that influenced this decision.

Pay attention to small things- Like WHICH Ruida controller is included. Or, the brand and model of laser tube- This one has a RECI W-4 tube, which is rated for 10,000 hours of working time, where many use a generic tube that only lasts about 6000 hours.

Lots of companies also advertise their lasers based on the Max power from the tube, which is a bit deceiving. The W-4 is 130w max, but ideal power is 100w. Think of it as the tube's red line- You CAN run your car engine above the red line RPM, but it's not good for it. Same thing with the tube power. And, tubes are NOT cheap- About $600 or so for a W-4.

Once I had the machine picked out, and specifications settled, they sent me a purchase invoice on Alibaba. Upon paying a 50% deposit, production started. Once the machine is complete, they will send me photos and a video of it operational, and then crate it up for shipping. Once the balance is paid, It'll be on it's way to me!

I looked in to this ahead of time. There are a number of services that specialize in this for small orders like this, and handle everything for you for a minimal fee. I haven't decided which one to use yet as I can't even get the process started until I have the final paperwork, but when I do I'll post details.

What gauge mild steel will an 100W (/130W) laser cut thru? I don't really know, just trying to get a feel for what the possibilities are.

Keep us posted on how it works. It could be an interesting possibility for both sides.

It does depend somewhat on what "percentile customer" the buyer is as far as their expectations, and how much interest the seller has in working for the customer after they've made the sale and collected their payment.

It won't. These lasers are made for woods and plastics, and etching, but not cutting ferrous metals.


As an owner/operator of a handful of different lasers over the years, keep in mind that when you opt for a US supplier it typically comes with hardware and software support. In the end, most of these lasers are using the same tubes and basic hardware, but where it counts, motors, bearings, software, firmware, is where stateside companies add their value. Most companies are buying lasers from China, stripping them of the junk and replacing those parts, pieces and code with their own supported engineering. Especially if you use these for production work, having someone who can pick up the phone when your rotary engraver is behaving erratically, can be a lifesaver.

If you're buying this to tinker, and not to make money, then getting whatever direct from China is certainly an option.

Very true. This is a 'hobby' item- I'll do some side work here and there, but it's not a primary source of income. It would be tough to justify spending $10k + more on a unit, even if it did have excellent support.

Many of the Chinese companies offer pretty decent support these days- Times have really changed. I work with 3D printers, and one of the primary companies I work with (China based) is as customer service oriented as the best US companies. They have realized that they need to be to be competitive.

There has definitely been an uptick in support from overseas. All of this also isn't to say that just because a US company provides support, doesn't mean its good support. There are a few US laser companies I've worked with that have provided some really questionable service.

The company I work for has 5 laser engravers 2 universal 1 full spectrum and 2 Chinese laser engravers with Ruida controller. I've been using a software called Light Burn on those. We have a dual laser that I was working on I guess that they've had for about 4 years I never could get it to work controller in it with a Ruida controller and it works okay it just seems to engrave a little deep.

Great thread, thanks for posting. Very interesting about the build to spec, sounds like a great option.

Ive had some hands on experience with both US based based lasers (Epilog and Universal) and some Chinese made Ebay imports. There is definitely a difference in the two.

Like others have stated, its mostly the interface software and support that lacked with our import laser. Cant speak to the long term performance yet.

If you have the time to tinker, adjust, problem shoot, then a ultra cheap import can be a good option. The benefit of the US based is generally, they just work. Interface controls make sense, easily tuned. Hardware is generally more robust.

Both Epilog and Universal support is falling off, we have had issues with both. Out of warranty cost money, tech attitudes can be tiresome, and connection times lengthy. But, they know the product and can generally get you up and running pretty quickly.

Im looking forward to the competition, the falling prices paired with improving tech is a win for the consumer.

I wanted to add a bit of experiential clarity to your question. 100-130W lasers certainly have enough power to cut mild or high carbon steel. However, you cutter needs other hardware to do this. My old employer had a Kern laser cutter. To cut steel we changed out the laser lens, used a sensor that did height following (the gap between the lens and metal was critical) and the system injected oxygen into the cut like a cutting torch. With a 150W I think the system was rated for up to 1/8" steel and could cut quite quickly. However, I never tried thicker than about 16 gauge. I also was never able to maser the setups that allowed such fast cuts. Instead I was cutting a very slow speeds, with low power. With such settings I had .007" cut widths when cutting thinner material (something like 0.8mm... sorry to me mixing units).

Maybe a new laser business. Maybe just blind now?

That idea about cutting steel with lasers and an oxygen stream is interesting.

Most lasers meant for steel do use oxygen to assist in cutting. When you get above 6000 watts, some use nitrogen to give a clean cut. I know a business that has a 9000 watt Amada laser that will cut 1/8 mild steel, with nitrogen assist, at travel rates in the 600 inches per minute. (if I remember correctly)

Take a look at Kern laser cutters.
The model I was using is no longer available but was something like 180W with an open bed. We had to be very safety aware around that machine.
