    Re: 1kW Chinese fiber laser cutter

    Razzmeister - can't just add a fiber source to a CO2 machine. You need a proper metal cutting head and a controller for it. It's heavy so you need servo motors to move the gantry. You need to run the...

    Re: 1kW Chinese fiber laser cutter

    You need a 3kW fiber laser to cut alu that thick. It's a tricky material to laser cut - much better to use a abrasive water jet cutter.

    Re: Considerations when buying a fiber laser

    1) There are no mirrors to align or clean. However you need to change nozzles according to what you are cutting and they need to be replaced from time to time. There is also a protective lens that...

    Re: 1kW Chinese fiber laser cutter

    Good to hear. My machine is also 1000W and I'm just waiting for the technician to arrive so I can get it up and running. Servos and drivers in mine are Schneider which is widely used so it will not...
  6. Re: New G Weike LG900N CO2 Laser purchase thread!

    First thing I did on my LG900N was to bin the auto-focus. They are a liability and just get in the way. If it malfunctions you could end up bending the gantry.

    I run my W2 Reci tube at 30mA most...
  7. Re: New G Weike LG900N CO2 Laser purchase thread!

    Hope you receive it soon and that all is good with it. I've had my LG900N with 100W Reci tube for a couple of years now and it's a workhorse. No problems with it and it has paid for itself many times...

    Re: No one could guess so far

    Check for belt tightness and also that all the sprockets are properly attached to the axles. Sometimes the grub screws are not properly tightened.
  10. Re: Bodor Laser 150w 1300x900 - NEW USER looking for help please

    Have you aligned the mirrors properly? That is the first thing to check. There are several guides and videos available, just Google "laser mirror alignment".
  11. Re: Small Business - Need to Cut/Engrave Birch Plywood - totally lost

    If you are going to be cutting a lot of 6mm plywood, 60W is on the low side. Personally I'd go for min 80W. I use a 100W tube for that but will buy a 130W next time.If you do your own impoort from...

    Re: Problem with laser. Overloading maybe?

    I can't comment on the controller but the water temp is way too high. You will have a loss of power at that temp and it will probably reduce the useful lifespan of the tube. Buy a proper refrigerated...
  13. Re: Looking for input on type of laser needed to cut 3mm bamboo with no charring

    Powerful air assist will help minimize charring but since a laser burns away the wood there will always be some discoloration. Maybe a CNC router would be a better choice?

    Re: 40W laser cutter not cutting thru!!

    You need to do an alignment. Judging by the look of the cut I would also say you are a fair bit out of focus.

    Re: Fiber Laser gas assist

    You can cut a lot of those shapes in an hour so cost per piece is not that high but of course you have to be able to sell them with a decent profit.

    Re: Fiber Laser gas assist

    Sounds about right. Depending on what you need to cut from brass and how fast you need to cut it, a CNC mill might be a more cost effective solution for you.

    Re: Fiber Laser gas assist

    You need a very powerful compressor to deliver enough air at the pressure required and it needs to be dry and filtered or you will very quickly contaminate the lens. The cost would easily be above...

    Hourly running cost of a water jet is high as well and you have the issue of contaminated water.

    Re: Fiber Laser gas assist

    I too am interested in the answer to that. I have not been able to obtain any solid information either. I assume you are looking at a 700W nLight source for brass? That's what I plan to use as well.

    No, fiber does not work with wood.
  24. Re: Kickstarter LightPhase 40w Laser cutter @2500

    Expensive and not possible to upgrade to a larger tube. Limited adjustability of bed height.

    Tubes have a shelf life. If yours is 7 years old, chances are it needs to be replaced.

    Don't go by percentages, check the actual current.

    Re: Choosing the right Laser Cutter

    I think ball screws are the better option with servos. Not sure belts will hold up at the speed/acceleration servos are capable of.

    If you just want to remove alu and not touch the PET then photo etching is the way to go.

    Re: Laser cutting/engraving aluminium foil

    Sending some samples of the material to a couple of manufacturers along with a test file for them to cut/engrave might be a good idea. Ask them to post a video on Youtube of the job being run.
