    My enclosure for the UC400ETH.

    No room inside the PC and no room inside the machine enclosure so it had to have it's own little box. :)

    Laser engraving 8 bit images.

    I have in the past noticed that with laser engraved 8 bit images on wood that some white areas of the image can appear to be whiter than the natural colour of the background material and I have...

    These are just some tests made (on cardboard) to try out the UCCNC Laser Engraving Plugin.

    Again, excellent work.

    Re: Photographic Image Engraving.

    The 8 bit images were not pre-prepared in any way, they were used just as they were downloaded from the net. However, those particular images were chosen for having a good level of contrast and no...

    Re: Photographic Image Engraving.

    This image has been 'dithered' (reduced to 1 bit) then etched into a white painted wooden surface.

    Re: Need CO2 laser recharged

    I don’t know why but…

    You can very nearly buy a brand new inkjet printer for the same cost as a manufacturer’s set of replacement inks.

    It is the same with a Synrad RF tube recharge.

  17. Re: Power Supply Malfunctions with the Mean Well LRS-350-24

    It sounds like over-current to me so just to be sure I think you should measure the current that is being drawn with a suitable meter. (To measure more than 10Amps you may need to use a meter + shunt...

    Photographic Image Engraving.

    I am really not quite sure why anyone would want to laser engrave a photographic image onto a piece of wood in the first place but, trust me, once bitten it does become addictive.

    Re: 2.5w laser wiring

    My advise is that you don't adjust anything.
    With diode lasers it is the Current adjustment that is critical and as many before have found the difference between Bright and Blown is a very fine...

    Re: 2.5w laser wiring

    You will have to ask the supplier of the laser / driver board to get the answer to that.

    Re: 2.5w laser wiring

    Sorry but that is not the way to do it.
    (By connecting TTL to GND the laser will never come on).

    Re: 2.5w laser wiring

    “You input 12V it will light on and when you input 0V to TTL it will turn off then when you put 5V to the TTL it will light on”.

    That is correct.

    It is not advisable to rapidly switch a diode...
  24. Re: Vector cutting paper on HPC ls 3020 (like k40)

    Certainly the first and easiest thing to do is check all the mechanicals. As Blackened has suggested it may just be something as simple as a loose grubscrew on the motor pulley / coupling etc..

  25. Re: Vector cutting paper on HPC ls 3020 (like k40)

    The vinyl dragknife issue is because the cutting tip lags behind the centre of rotation (this is necessary to get the knife to 'steer').
