I gave a description of the difference in the settings on the engraver between the engravings in the first two images. The second one is slightly lighter because it traveled at a speed of 2000mm/s instead of100mm/s both at full power and a frequency of 20khz.

Even I have the same issues despite the fact that I posted it. I'll try repairing posting.

Here's the test you mentioned Janger, on a 10 gauge mild steel flat bar. The first picture shows the results with the laser set to a speed of 100mm/s, and a frequency of 20khz. The second is 2000mm/s at 20khz and both are 100% power. The laser did a surprisingly good job engraving at 2000 in...

Welcome Dave, from Calgary. Ive also always been interested in electronics and robotics. before I was introduced to metal fabrication I attempted to become an electronics engineering technologist. Some parts of that were too complicated, so I ended up withdrawing. However that ended up giving...

The g2max could easily cut through 2mm thick metal in 1 pass if you set the speed below 100mm/s with a lower frequency, but it's most often beter to run more passes at higher speed. I engraved my own portrait onto this brass coin which didn't take all that long, and it did come out in finer...

I Decided to go for the Gweike cloud g2 max 50w fiber laser. I did some research on Gweike, and their recent cloud g2 pro 30w fiber laser turned out to be very popular with good reviews. The g2 max is basically an upgrade of the g2 pro and they had it on sale for nearly 50% off which was an...

I should definitely check that out, thanks for the notice. I first assumed that my 40w diode laser would be able to perform just as well, but I remembered the benefit of ir and fiber lasers in comparison to high powered diode lasers. I do have an ir module for my D1 Pro but that only has an...

I've done a ton of research on laser engravers and watched many reviews on YouTube from experienced people who either do it for a living or have been reviewing them for a living. The new OneLaser XRF ranked number one in most videos for it's high quality at a mid cost. Standing between hobbyist...

Fiber lasers are the best for cutting and engraving metal. Not only because they are within an ir wavelength, but also because the laser source generates a more concentrated beem of light than a co2 or diode laser. A 30w fiber laser can cut thin metal, and engrave/carve 3d images into thick...

Id say I have tthe most I could get out of a single car bay. My shop is part of our 3 car garage separated from the 2 car bay by a wall that was installed after we moved in. I still live with my dad as I don't have a very high income, an he has noticed that he makes almost no use of the garage...

I,ve been looking for a reliable milling machine below $2000. I already have a vevor mini lathe which isn't as big as this. To save space I'm thinking a combination of the two would be a good option.

As much as I know about nonmetalic 3d printers I think I would only use it for modeling purposes or for plastic components that don't take much wear and tear. How reliable are 3d printed parts anyway? I built my own 3d printer with stepper motors to run a belt drive for the nozzle gantry, and...

As much as I know about nonmetalic 3d printers I would only use them for modeling purposes or plastic components that don't take much wear and tear. I built my own 3d printer with stepper motors using a belt drive for the nozzle gantry, and lead screws for the hot bed. The machine's controller...

Ah, a router would definitely be easier than a milling machine, though they basically work the same way. I tried building a milling machine, and the gantry worked just fine but the spindle was definitely not powerful enough to work metal. I didn't have as much knowledge of how the spindle on a...
