Figured out how to bypass it. I entered the machine in manually.

Apparently I'm part of the problem. The laser is coming straight from Hong Kong. Says it shipped on the 12th and will be here the 16th.

Holy crap that's fast

Talk is cheap.

I ordered some stitching twine a few years ago. Shipped from China.
Took a month.

Shipping DHL. The company says they won't use UPS anymore because of disputes with a single damaged order. I didn't even know DHL was still in the US. I had a buddy that worked deliveries for them years ago, got laid off when the shut down more or less.

Most commenters on the site say 4-8 days.

Got a tracking number?

My stuff came by ship. Sounds like yours will take a jet.

I brought the box to the shop and assembled the engraver. I watched the assembly videos 1/2 dozen times since I ordered it assemble was done more or less without instructions. The only part I had to go back to the video for was the zero Y axis limit switch. Most of the videos didn't show that detail so I had to look around to find it. Took about 20 minutes to put it together.

Then I cut a board, made some corner stops and mounted the laser engraver to it. Then I made a program that put grid lines on the board that were 1/2" square to ease alignment along with a center X.

The first program I ran was my logo

510959

I did several tries at it to figure out what worked best. Takes less than 30 seconds

Then I did an Owl for my wife. Took about 1 minute

And then I had a dragon that I did. Took about 8 minutes.

My brother is getting a standard poodle without the haircut normally associated with it. I'm making him a burning of a poodle that I modified the haircut. His name is Elroy so we also included a picture the the Jetson's Elroy with a jet pack on.

Still working on it now It'll be my longest burn at about 2 3/4 hours. Making a guy in a boat catching a fish for my Dad next. That burn will be a bit longer.

Did a business card on Aluminum stock with a black paint. Right at the limit of what my laser can do I think. 100% power and 100mm a minute for good results.

Ya, that laser isn't getting anywhere near that.

So during the day I modified the program and ran about a dozen business cards. The first one, shown a few posts above was done 100% laser power (~5.1 optical watts) and 100 mm a minute (4"/min), took 46 minutes. I started playing around with the power and found that 90% seemed to be the magic number. Running the laser at 100% will shorten it's life a lot faster. I was able to get it up to 400mm/min (16"/min), I think it was down to 13 minutes a card.

I had to go get a contract signed and was going to give the guy one of the metal cards. On the back of the cards I was writing in magic marker the speed and power I did the card with so I could find that magic number that gave me a nice looking card with the least power and fastest speed.

So I used Denatured alcohol and wiped the magic marker off the back of the card, wanted to make sure it didn't damage the coating - it didn't. So I wiped the front of the card that was engraved and it just lit up. I figured out "the secret".

So I was able to do a few more cards before I had to go get the contract signed and then after I got back I kept going. I was able to get it up to 550mm/min and the power down to 70%, time for the run is down to 9 min 30 seconds. But I have to clean it off with the Denatured Alcohol to make the card light up. I guess it's the ash left behind that is making it look dull, the DNA cleans all that off.

Well with "the secret" I was able to bump the speed up to 700mm/min and the power down to 20%. I can do a card in about 8 1/2 minutes. The machine is close to it's limits for speed, it can't go faster with the small movements the letters require. I don't think I'll be able to get the time down much further unless I eliminate lines of text.

Here's before and after "the secret"

I made something for the back of a card for when I finish up a job I can toss it in a drawer. It'll have the business card on the backside.

I tried a pencil and it worked. I filled it with colored wax.
