    Default about to buy a chinese laser co2 machine - advice required

    hi there,

    i am about to buy a chinese/ebay co2 laser engraver, im in the uk and my budget is £2000

    from what i can tell with my limited knowledge is it will engrave pretty much anything other than metals which it will mark with a spray treatment.

    i am a car trimmer and i primarily wanted it to work with leather and alcantara materials, but since looking at them im sure i would use it for much more


    some of the machines ive seen are rated at 60 watts and come with a rotary attachment (like and lathe chuck), others come with a better exhaust fan but no rotary thing, and t the top of my budget one comes with a proper water chiller and a rotary attachment - not the lathe chuck type but seems to be better as its not limited by the chuck size, this one is £2000 giv or take a few pounds.

    the trouble i see with the most expensive one is it doesnt support multi colours so i couldnt cut and engrave in the same job - i assume thats the only way i can do that (again limited knowledge)

    is the multi colour function to control the power/speed really needed or just a nice thing to have?

    any help and advice is going to be very helpful

    thanks

    I highly recommend buying a machine with a true "DSP" controller like one from Ruida. The Ruida controller uses software called RDWorks/Laserworks. The Ruida control panel typically looks like this:
    RuiDa RDC6442G CO2 Laser Cutting Engraving DSP Controller System | eBay

    RDWorks/Laserworks lets you set different elements different colors/layers. Each color/layer can be set to either engrave or cut (at different powers/speed).

    There is a great new user group for users of the RDWorks/Laserworks software at rdworkslab dot com.

    If you are going to be using your laser for long periods of time (hours per day), or your ambient temperature is high, then I would highly recommend a chiller to extend the life of your laser tube. Different manufacturers have various recommendations, but generally the cooler you can keep the laser tube the longer the life. I keep my chiller at 19 degrees C for a 50W laser. Before I had a chiller the water temp would go up to 30C pretty quickly, especially during the summer, which is not good for long tube life. Beware, the cheaper chillers (e.g. the CW3000) are actually just radiators and can only get the water temperature down to ambient. Chillers like the CW5000 and the ones on Lightobject dot com are actual chillers (i.e. they contain refrigerant and keep the water at the temperature you set).

    I wouldn't worry about the rotary attachment unless you definitely have a use for it. I have never used mine. I am sure you could buy one separately if you do start to have a need for it.

    Hi,

    The below is my suggestion,hoping it can help you.

    1.For engraving on leather and alcantara,40W/60W both are ok.

    2.For the leather,alcantara materials is soft,so i think it should not need to use the rotary attachment.

    3.Need to use honeycomb platorm.

    4.Can you tell me what is the thickness of the leather,alcantara? If you cut,thickness is needed.

    5.What is the length and the width of the materials?

    6.Exhause fans ,all are machine have.

    7.For the chiller,usually 80W laser tube or bigger,we will suggest install.

    If you have any other question,please feel free to contact with me. My name is jenny ,i am in the fields nearly 8 years ,email is toyealasercnc@foxmail.com , jenny@toyeacnc.com . .

    thanks,i wasnt suggesting id need the rotary for the materials,maybe for glasses or bottles

    material will be 1.5mm max,

    i know they all have exhaust fans just some are the centrifugal type and are more powerful

    thank you thats very helpful ill make sure mine has the colour separation capabilities

    Looks good, best of luck! Search for a user called SarbarMultimedia (Russ) on Youtube, he has a lot of really informative videos on a similar (smaller 50W like mine) laser cutter.

    thanks will do, need to buy a proper water chiller i think and an ammeter, keep an eye on the laser stats so as not to allow it to run too hot and over power it shortening the life, from what ive read anywhere

    Yes, definitely add an ammeter. It is pretty simple to hookup and gives you great info. to prevent overdriving your tube. I bought a 0-30mA ammeter for around US$7 and it works fine.

    Also, keep in mind that the 60W tube is probably over-rated. Mine was sold as a 50W laser, but based upon the diameter and length of the tube it is most likely a 40W tube at best.

    think mine is an 80w, where do you connect the ammeter up to thats what i dont know, also what would you say is the max mA i should run my tube to?

    cheers

    I followed these instructions (although I mounted it on the laser tube extension plate on the side of my machine).
    LensDigital - How to add ammeter to 50W Chinese laser cutter from eBay

    I don't know the max amperage for an 80W, but the safest thing to do is either go on the laser tube manufacturer's site (if you can figure out who actually made your tube) or go to lightobject dot com and look at the specs for a similarly powered tube. Lightobject's website tells me that for a true 80W tube the recommended amperage is 26mA (28mA max).
