Hi,

I was at the recent 2016 Linux Australasia Conference and one of the Hardware speakers gave a talk about the 40W Chinese laser that be purchased off ebay for $540: http://mirror.linux.org.au/linux.conf.au/2016/01_Monday/D2.211/LinuxCNC_for_fun_and_profit_now_with_deadly_lasers.webm

Searching around a bit I found this Sydney ebay store (just a front for a Chinese entity?) that sells a range of 40W, 50W and 60W lasers:

1) 40W http://www.ebay.com.au/itm/High-Precise-40W-CO2-Laser-Engraving-Cutting-Machine-Engraver-Cutter-USB-Port-CE-/181839157710 but a smallish working area: 300MM*200MM but a smallish working area: 300MM*200MM. PS. there is one cheaper in another store.

2) 50W http://www.ebay.com.au/itm/50W-CO2-LASER-ENGRAVER-ENGRAVING-MACHINE-CRAFTS-USB-PORT-CARVING-ACTIVE-DEMAND-/221930473022?hash=item33ac16463e it’s $1957 and has a cutting area of 300x500mm (this has been discussed in other 2014 forum entries)

There are a number of good reviews on it, for example: https://www.youtube.com/watch?v=djgNTUiwaXQ and https://www.youtube.com/watch?v=GQE9xG3COww It doesn’t have a good cutting bed (discussed in one of the reviews). In the second review, the guy has replaced it with a cheap screen (also mentioned in the previous 2014 forum entry)

3) 60W http://www.ebay.com.au/itm/LASER-ENGRAVER-ENGRAVING-MACHINE-60W-CO2-GLASS-TUBE-CUTTER-DSP-CONTROL-FANTASTIC-/331758556215?hash=item4d3e59d437 it’s $2900 and has a cutting area of 500x700mm proper laser cutting bed and it’s on wheels, so it can be gently moved around a bit. Free shipping (185Kg) to anywhere in Australia!

Just wondering if anyone has purchased either the 50W or preferably the 60W recently (2015/2016) and what their experiences and feedback might have been on the laser?

Thanks

Cheers, Paul

Hey there

I have not brought one, but I am thinking about the large 60w one but
putting it in my flat. I want to make sure my apartment wont A) set off
the fire alarm every time I use it (a expensive endeavor) and B) make the
place smell of burnt perspex all of the time.

From what I heard of the smaller ones is the controller is not good and it
is best to tear it out and replace it with the same one we have at the
space (I have a one at home that is not doing anything) but I am not sure
if that is the case for the 60w one.

But my research is very old and should be taken with a grain of salt :)

Cheers
Stephen.

Having purchased a laser for work recently (and, btw, I don't recommend Red Dot Machinery here in Sydney unless you are willing to trade sanity for a discount), I think I concur that you get what you pay for, and it's quite likely that you'll have to replace bits as we have.

One story of many from my experience: We got a filtration unit that seemed to stop working not long after it was installed. Turned out that a piece of connecting duct between the filter stack and the blower unit (which sucked air through the stack) was not designed for a vacuum -- it was made of two layers of vinyl tube laminated with reinforcing coil in between. The inner layer completely delaminated from the outer layer and collapsed every time we turned the fan on...

I could go on, but in the end after lots of time and many in-house improvements/fixes we now have a very nice machine.

Paul check the archives, I posted about the $2000 50w I bought about 5 months ago.

It's awesome. And it was delivered the day after I bought it. Imo the cheaper ones without a real controller will just be a disappointment.

Hmmmm...

That small 40W one at ~$530 is very tempting. There's a lot I could do with a 300x200 cutting area - especially when the 300x500 one is four times the price.

But I don't know just how crappy the cheap and crappy end of the laser cutter market is. Sounds like the guy at LCA did a _lot_ of futzing around to make hs do what he wanted (tho it's unclear how much of that was the usual "I know, I'll do this with Linux! Now I've got _two_ problems." caegory of stuff (understandable if he had an existing workflow, files, and a wife who knew how to drive his old one, it'd be worth the futzing time to make the new one "work the same")

I'd love to hear firsthand experience from anyone who's tried one of these with mostly stock parts and software, to do things which seem relatively straightforward - stuff like cutting tabbed boxes, flex boxes with those bendy plywood hinge/curves, wheels, pulleys, gears, small robot chassis. Just straightforward shapes in 3 and 4mm ply. (40W should cut 4mm ply right? Wasn't the space's original cutter only 40W? The one we had at Kogarah? If one of these would do what that one could do 3-4 years back in 200x300mm sizes, I'd be all over it...)

At $530, even if it's crap, it's tempting. It'd have to be spectacularly crap to be of no use at all - I wonder just how frustrating it'd be getting to the stage where I was getting usable parts from it?

Yeah, sorry. I forgot to add the obligatory YMMV :) As I said, we're now very happy with the hardware, it's a great machine for the most part.

We were looking for something the next step up (100W+) and I didn't see anything comparable in the archives. We were tossing up whether to import our own G.Weike (many people have had great experiences) or buy through a local outfit. We decided on local so that we'd also get local support, but unfortunately I wish I'd gone with the G.Weike, it would have been much less trouble.

I can put you in touch with someone at work who bought the $540 model late last year and he'd be happy to tell you all about it. PM me off list if you're interested.

If you don't want more bed area paul, just put 100w parts in yours. My $2000 50w has a 60w power supply /tube in it. They even have a removable plate so that the longer tubes can poke out :)

The ~$600 units are essentially the same as the first laser the space bought.

The boss wanted a much bigger bed and motorised Z-axis. We ended up going with a 1200x900 @ 135W. You said "Just put the 100w parts in yours" - I don't have one. A mate has the 40W.

Thanks for all your info. I bit the bullet and purchased the 60W unit. Mainly for the bed size. Plus I can upgrade to a large tube if needed at a later date. I will let you know here what it's like.

Cheers,
Paul

Ok, the Laser arrived a bit over a week ago.

The crate packaging was a bit dicey, so it arrived with one end of the crate flooring broken off.

It turns out that only the front stand(?) was bent, so I straightened it up and all is ok. I didn't take into account on how I was going to lift a 125Kg machine 30cm into the air, so I could remove the boxes of parts underneath the laser. Also, how do you get it off the packing crate box floor late at night without four other people around to help lift it off? I ended up spending 1.5 hours levering the unit up via bocks, then removing the boxes and the pallet, then levering it down block by block.

There are nice English labels on all switches and inside parts, however, when I powered it up, I found that the LCD menu was in Chinese! I am still working on a fix (or firmware upgrade) that with the eBay supplier but not holding out much hope (see photo above)

It turns out though that I mainly print directly from the local computer, so I don't really need (at the moment), the LCD. The LCD does display the what's being printed, the layer power settings etc, so that's ok.

I spent the last weekend testing the cutter out on a lot of different materials: paper, 3mm cardboard, fabrics, a few metals, glass, ceramics, a few plastics, plywood and 3mm and 6mm MDF.

For other people looking to purchase something similar, or benchmarking, I found the 60W laser would cut:

3mm MDF at 10mm/sec at 70% power
6mm MDF: two runs of 10mm/sec @ 80%
80g/m3 paper,: 200mm/sec @ 20%
most fabrics: 100mm/sec at 30%
2mm glass: 50mm @ 15% - a light ablation, 100mm @ 30% gives a deeper ablation
3mm acrylic: 10mm @ 90% - clean cut

I was hoping that it could cut 6mm MDF in one pass. I did try cutting the 9mm crate plywood, but it struggles to get through the last layer. I have yet to try 9mm MDF.

Things I like about it:

the proper cutting bed material
the 500mm x 700mm cutting bed
it's on wheels
robust construction
only had to pick up distilled water and a 20L Bunnings container/bucket and it was all up and running
software is easy to use and seems to recognise my DFX drawings from the latest versions of Inkscape and Design Spark Mechanical.
while repairing the switch, I noticed that the controller has a RJ-45 port. I have yet to test this out.
comes with a software and hardware Chinglish set of manuals.

Things I don't like about it:

the air suction fan is very noisy and vibrates around. This was mentioned by a 50W Aussie video reviewer, so no surprise there. It does pump out a lot of air! The fan motor gets too hot to touch if it's been on for an hour or more.
be nice if one could continuous feed material through the front/back slots, but the design is 20mm out. Maybe the laser head could be lowered?
the laser has a ~ 11mm focus path. If it was longer, it might cut deeper in one pass? Maybe a different lens might fix this?
The main switch failed in the 'on position' on the 4th day!! Luckily I could disassemble it and reset the internal arm. I ordered two more from AliExpress, just in case.
Chinese LCD menu (some English), not a show stopper yet.

Would I purchase it again?

Yes! Of course, I would love a 135W or a 150W laser to easily cut thicker wood, but for the moment, I can live with what I have. Maybe in another few years, the tube prices might come down some more?

Cheers,

PaulH

PS. excuse the photos, as I haven't figured out how to properly insert the photos into the post. PM me with your email address if you want more/better photos of it.

it's not the same model as yours but the screen looks veeeeeeeery similar.

Can you let us know which model and supplier you went with in the end?

Paul mine was in Chinese as well but there were instructions online to navigate the menu to change it to English.

Your cut sheet looks a little wrong though, you should have more power than that.

Thanks for the write up (good job)

As I have a DSP controller from lightobject I would be happier to get the
laser with just the mechanical bits (without the tube, PSUs, wiring (heard
things from CNCZONE about it) mirrors lenes etc) and build it the way I
want it built.

i'm genuinely not Trolling, how would your design differ?

in a few months i'll be building 'an interesting machine' and i'll be using coreXY* framework (because the motors will be big and heavy and the bed will be huge). I'm collecting design tips from others who are custom building things* and am interested in 'problems' with existing designs.

i know, oh god i know, i should build a little version first and work out the kinks in my design but no, i'm going to order the giant steppers, the 10m toothed belt and the equally giant drivers and get 60% done before i realise my design is fundamentally floored.

Also, Paul, how are you handling filtration?

Hey there.

The design would not be different but I have heard that there are issues
(varying from machine to machine) about wiring, people putting in lower
then the 60w lasers etc. One of the power switches on Paul's has already
failed. Also I already own a controller so I like to use that one.

The write up that Paul did is extremely useful. Thanks mate.

Here is the post on CNC Zone I was talking about

That;s the true hacker spirit I love to see!

Please please please make sure you've got several video cameras pointing at it the first time you power it up - including high speed ones if possible - the _last_ thing you want if for this to spectacularly destroy nearby expensive appliances or bystanders without it getting recorded for amusement^h^h^h^h^h^h^h instructional purposes...

Kris,

I happen to be doing something similar - happy to discuss all the gory details and planning progress with you off-list. :-)

Bingo, that did it! Thanks Kris, I now have an English menu.

Yes, there is a nice big QR code sticker on the front of the Laser unit, which decoded says:

If it's worth anything, this is the label on the Laser tube:

I am presuming that the laser tube length is proportional to it's power? If so, this one is 1020mm long.

It would be interesting to hear how long the other 40W and 50W tubes are.

Cheers,

I used the LCD menu to set an IP Address on the controller. I can now ping it, but running NMAP against the IP Address says that all ports are closed:

All 1000 scanned ports on <IP Address> are closed
MAC Address: 02:A0:C9:78:3E:63 (Unknown)
Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port
Device type: specialized
Running: RF-Space embedded, WIZnet embedded
OS CPE: cpe:/h:wiznet:w5200
OS details: RF-Space SDR-IP software radio or WIZnet W5200 TCP/IP Ethernet chip
Network Distance: 1 hop

Has anyone been successful in doing anything network wise on their laser controllers?

Cheers,

PaulH

The software for mine has the option to upload over ip. it's much faster and more convenient.

It's called RD draw I think?

Paul, the report said "All 1000 scanned ports". Suggests to me that it is only scanning the "well known" ports. You should try doing a scan on the entire port range (65536).

Yeah chances are it's not running on one of the well known ports... Suggest you run a full scan. My go to scan settings are as follows... just replace localhost

nmap -sS -p- -P0 -T4 --osscan_limit --osscan_guess --host_timeout 15m
--max-retries 0 --min_parallelism 100 --max_parallelism 500 -O -oX -V
localhost

Of course if you don't want to try to discover EVERYTHING about the host, you could just run nmap -sS -p- localhost
