Re: Best settings for dithering on anodized aluminum for DSP

If you put the bed closer to the lens without getting a lens with a smaller focal point the opposite of what you think will happen will happen. The dot size will be larger. If you cut a cross section through a laser beam it looks like a sand timer. First it's large, then is small at the focal point ...

Re: objects sometimes are displaced

I get similar things happening. I've opted to upgrade to a closed loop system. I had a fire in my laser anyway so decided to rebuild the x axis with closed loop. At least you can eliminate a few things then.

Re: Any Lasercad alternative out there?

Importing an AI file never seems to work properly, it either loads it weirdly or doesn't load it at all, stick to exporting to DXF. I've never tried the illustrator plug in as I use illustrator on a Mac.


I find Corel works the best with LaserCad.

Always have a fire extinguisher handy

IMG_3555.JPG IMG_3551.JPG Looks like some of the stepper wiring or microswitch wiring caused a fire and stopped the head moving. Luckily I had an extinguisher on hand. Most parts are recoverable luckily. Mirrors and lenses seem ok. Laser still fires, no mission critical metal warped. Melted plastic...

What problems are you having exactly? I am in the UK and although have a friend in Wisconsin I cannot travel to you but can offer advice :)

Re: Best settings for dithering on anodized aluminum for DSP

In your image editor resize the image to the size you need it. Resample the dpi to match the dpi you are engraving at (1000dpi) Convert it to grey scale to get rid of the colour. Convert it to black and white or 8 bit bitmap. ( depends on what the software calls it) Choose half tone and tell it he n...

Re: Multiple lasers on one water reservoir and chiller?

On a similar note. What are people using as an anti mould growth solution. I've had issues with this, initially I thought it was algae. But after trying anti algae drops I found it wasn't algae but mould. Options seem to be hydrogen peroxide, Milton or a few drops of iodine. Put a sterilising tablet...

Re: Multiple lasers on one water reservoir and chiller?

It will work in some form but if they are all running all day you might find the chiller will struggle. I wouldn't run them in series though. I'd try and do it in parallel.

Re: Any Lasercad alternative out there?

Yes. You'll have to break the line. There aren't any alternatives as far as I know unless you get a new controller from light object. Marco has been developing his own software. Just had another thought... You could create your own custom dotted line in Illustrator ( long lines with a small gap) and...

Re: Melting switches

Something is drawing too much current which means something in your laser cutter that runs on 240/110v is probably faulty and needs/fixing/replacing.

It would be a case of measuring the amps draw by each component to see which one is being naughty.

Re: new tube > cutting works, engraving not (lo x7)

Have you adjusted the integrated potentiometer on the laser psu so it's giving enough current?

What is the PWM setting at the moment?

That's all I can think of.

Re: Confusing regarding wiring co2 tube

I'd look at the other end of your 'big red wire' . Make sure it's connected to the +ve terminal. It might have been connected to the -ve and whoever wired it up originally did it backwards. It's definitely the other way around. I am not sure if a tube will work wired up backwards but from a safety p...

Re: Maximum engrave resolution of the AWC608?

smile well I am only going on all the other websites I have read and there can be a lot of mis information out there. I think what they are getting at is if you choose a scan gap less than your dot size then you can technically get over burn. .
