What is able to do this laser engraver? As I am from Romania, what would be the additional cost of shipping it to me? I would like to buy one, but for this I must borrow money and I need to know exactly what it means from cost point of view. Actually, I would like to start (finally) a small business based on my CNC knowledge got here and by building three machines (two MDF and one AL). The machines I do not think can sustain even a small business, but a laser could be a start....I hope...

Hi, I am about ti buy a laser engraver, so far I,ve decided for artsign JSM3040N or Wklaser LG3040, wich one do you reccomend me?, artsing seems to have more information about their products and about $400.00 USD loer price, but I have read bad comments about the label in some forums. Please help!.

[zax15uk]

Hi,

The Artsign systems are generally well built and use similar quality components to the Rabbit and WK machines.

I am not familiar with this particular model (desktop with DSP) so can not recommend one above the other.

Zax.

[paolacasas]

Hi zax15uk Thank you for your advice, anyway I´ve decided for a wklaser because it can be used with a rottary attachmente and the artsing doesn´t, also they offered me a better machine for almost the same price, I am now satisfy (si far) as soon as I have and use the machine, I will post my comments because it is really usefuel for the people that is looking for references of this machines. This forum helped me a lot to decide my buy. Thank you and Regards.

So you want buy laser direct from China or from local dealer? Looks like for you is better buy on local market and have support on Spanish, than buy in China and spent weeks trying get support mix of Spanish/English/Chinese

hello,
can anyone advise me of what size nema steppers i need to run my new mill router table x=1000mm y=1500mm z=450mm,
cheers,
lee.

[zax15uk]

Lee,

It varies depending on your machine configuration, driver setup (microstepping) etc.

If you are running standard leadscrews and a full size router, you'll want at least a double stack NEMA 23 (high torque) or NEMA 34.

Zax.

[leepi]

thanks for the info zax i was thinking of nema 34 (800+) torque but not too high as when ive read up bigger motors give more problems is this true,
lee..

[zax15uk]

Does you machine have any motor mounts? If so, it would be much easier to go with the motors that fit rather than having to use adapters.

As with any mechanical design, added mass (NEMA 34 vs. 23) can cause problems due to inertia. If the same leadscrew or belt drive pitch is used this will result in lower acceleration and deceleration especially when changing direction (corners etc). Of course you can have different gearing to solve these issues but overall speed will be lower.

If the torque from double stack (or even 3-stack) NEMA 23 motors is sufficient it will usually provide faster speeds and better acceleration compared to a similar NEMA 34. It depends what is most important, speed or torque and how you gear the system. Torque drops significantly as speed increases but once the mass is moving it is less important unless you are moving a large end mill through metal.

I would need a lot more information to say whether the NEMA 34 (800 in-oz) steppers are suitable or not, but they do sound over rated for a typical mill of the size you mentioned.

Zax.

[vivinar]

paolacasas, i am looking forward to see your comments about your laser cutting machine.This is also very important to me to know the other company's machine.haha.
And now our company is also produced another ballscrew laser cutting machine,180w.
The XY axis is used ballscrew to improve the precision.
Any people insterested can contact me .

good day, I hv a rabbit 3040. yesterday it function good. but today when I on it, the x & y don't move. even I tried to reset to x y, it no reaction. everything is good, the laptop n lighting. but the x y don't move. can any1 help me on this? much appreciate...

[fantasy2]

Can you manually move the x and y? If not, maybe they hit the softstop.

If you can move it, there is no power on the steppers. For that you should check the controllers.

[zax15uk]

fantasy2 had some good suggestions, here is what I would try:

Check/Reset EMO switch
Check fuses
Check driver board (LED's)

Hi all
I would like share my experience between and USA laser cuter (EPLOG 1280) and Chinese laser cuter from xyz-tech . (EXLAS).
We do architectural models and we did use the EPLOG for cutting and engraving mainly acrylic and soft wood. The decision come from me to employ a big laser cuter machine (120 cm*80 cm) . after a lot of browsing and checking throw alibaba.com we came to decision to order the EXLAS 1280 machine. One of the main decision was based in ordering from small or medium company size, as my business experience large company do not offer expellant online or distance after sails services. They need a local dealer to do that. We don’t have local Chinese dealer as far as I know in Saudi Arabia. We do have EPLOG one, and the service is bad unfortunately. I will be very short for the comparison according to my experience.
Laser tube.
EXLAS use 80w CO2 glass tube, it is much powerful, much more than we need actually, but we are pleased with the result in cutting 5mm acrylic from one pass,(speed 15. Power 40). With the EPLOG (30w RF tube) we need more than 5 pass same speed and 100 power (after 6 years of service) . I think RF tube are stable and can run for long time (10 hours or more) with no problems, CO2, I am not sure, we need more time to find out. And we don’t need too much time for cutting due to its high power any way, I do have plan to test it heavily and I will let you know in the future.
Engraving.
EPLOG can except 256 gray bit map directly from CorelDraw it simply make you life easy just print directly to the laser driver, laser will fire more points at dark areas. And less points at lighter, EXLAS laser cut 5.3 dos only use 2 bit files so you have to do it yourself and result are so similar, the result if favor to EPLOG, it really do semi 3D engraving feeling. But with some knowledge in Photoshop you can get excellent results with EXLAS. Put in your mind if you are doing only engraving 30w laser tube has sharper result and higher resolution.
Architecture.
EPLOG and EXLAS are so similar from my point of view. I am not and electrician or mechanical engineer, but I can have an overall feeling, EPLOG looks more hardly built, but it is smaller than the EXLAS, the EXLAS design is much beautiful (I am an architect) only the cover I don’t like, Bothe machine has pass throw material, lifting table at EXLAS has 2 motors, at EPLOG only one, and one day was broken and we replaced it.
Electrical and boards. Again from what I can see how the EXLAS are working it is smooth, and fast, no big deferent , but EPLOG movements seems to be smother. And less noisy. Maybe because it is smaller.
The electrical mother board and power supply, and X & Y & Z drive are located nicely at the side of the EXLAS, (and all other Chinese laser) EPLOG is under the RF laser at the back of the machine, it is mint to be like that so nobody play with it only their authorized engineers. EXLAS for me is better where I can do the maintenance much easily. At my town no EPLOG or any Chinese manufacture dealer are there. I do have to admit XYZ EXLAS have excellent online distance after sails service .
Working
We did use the EPLOG for 6 years, and EXLAS for only 4 months, it is not fair to do comparison hear, but I can assure you the next 6 months we will put the EXLAS to the extreme working environment. We do have plan to build a city model (7m by 4m) (22ft by 13ft) we will do thousand of small houses cutting and engraving, hopefully the EXLAS will do most of the job, as an professional I do not recommend one machine in an office for work. You have to put in your minds a down time is always happen, even when we have only the EPLOG. We do experience a power supply broking, working table motor broken, we did scratch one mirror, still we did not replaced it yet, so another machine will be very good.
Software.
EPLOGE has a printer driver, you can use it from coral auto cad directly, EXLAS use lasercut 5.3, it is similar to the very old coral program (DOS golden days if you are old) . You have to import artwork from coral and send it to lasercut, for me it is okay, I do prefer direct sending, but also the lasercut is doing fine, it has some bugs, (as any windows base programs). Do use it carefully under windows XP only. And do not load any memory base program while firing the laser. Spear cheep old Pentium PC only for the laser will be good idea,
Final
Final product results are very similar, but Chinese laser you have to do more study and tests until you can produce perfect cutting and engraving, USA laser are much easier, something like PC users, PC with old DOS operating system, and windows, Chinese laser You have to use it carefully, get an industrial water chiller, study will about laser safety. You will need it for when you replace the tube, or test the power voltage or when you place water very close to high voltage wiring.
Tomorrow at light time I will post pics about our old EPLOG, and EXLAS.
Thanks an sorry for long text and bad English

Thanks for your review/comparison! The chinese machines indeed need more work to cut material and the software is crappy. I also wanted an epilog machine but the price was just too high to start my business with. I think that as long as you have technical skills and exactly know how the inner works, using a chinese machine for production is OK.

I used my 60Watt CO2 glass tube for about 8 hour yesterday non-stop, I still had enough power to cut through 5mm plexiglass. I'm using the more expensive industrial cooler that really cools the water instead of recirculation only. The water temperature is about 25 degree celsius continuously so that's nice.
