This is replacing an Ortur M2, that I got about 5 years ago. The Ortur developed some Y Axis problems, and we couldn’t trouble shoot enough to determine if it was the motor or the control board. Replacing both brought the price too high so, I went searching. I was looking for something that didn’t cost a fortune. All I really use it for is printing my logos on the back of my wood crafts. I was sort of striking out on Amazon, so I expanded my search and read a couple of blurbs which led to Youtube’s of the Acmer. Interestingly, Amazon’s price for the P1S was $250, where the company website had it on sale for $199, with free shipping. Twisting my arm here.
Then I saw the kit that included the rotary device for another $80. That sounds like fun, so I bit on it. What was interesting was the riser legs for the kit arrived a few days before the laser, with no explanation as to what they were.
The engraver -- Putting it together was interesting. It comes with an instruction book, which is mostly just pictures, not, really, enough instruction text for some beginner types. There are Youtube instruction videos from both Acmer and some “Experts”. The Acmer videos have no voice instructions, just a person putting the laser together to some music. If you watch the Acmer videos about 3 – 4 times and check out the other videos, you shouldn’t have too much problem. One expert said it takes about 15 – 20 minutes to put it together. I would recommend setting aside about 4 hours. If you pay attention, it will go together very easily. Acmer is kind enough to include a USB adaptor with an SDC card that holds videos, test files, instructional PDF’s, copies of LsrGrbl and LightBurn (Note: Lightburn requires a subscription fee). That’s a big plus for Acmer.
I like the construction of the Acmer over the Ortur. I like the legs that are corner angles vice the Ortur flat plates. And it is a 6-watt laser vice the Ortur 5 watt. It just feels like a more solid frame.
My Lightburn software picked up the laser quickly, and in a few minutes, I was printing a material test. I don’t cut wood with the laser. I am a scroll sawyer, and it is one of my fun hobbies, so I’m more into just engraving. I don’t even have a honeycomb tray for cutting wood.
One issue I had with the Ortur, was getting the laser focus just right. Since I engrave items of different heights, I was always erring on the side of safety and sometime had to do a second burn. Acmer gives you a little piece of aluminum dowel, exactly 23mm long. Remove the safety shield, set this dowel on your work piece, and drop the head, so it just sits on the dowel. Done – your focus is correct. Unfortunately, a gadget like that is easy to lose. I cut 3 more out of some UHMD stock I had and keep them in a drawer be the laser. I also, drilled a hole, in my laser board, to hold the aluminum one.
I really like this laser. At $199, it is an excellent beginner’s laser. It’s solid and should last for some time. Even at the regular price of $250, it’s a good buy.
The Rotary Attachment –
You connect the rotary device by unhooking the control cable from the Y-Axis motor and using an interface cable to connect the motor on the rotary device. I’m not a big fan of constantly disconnecting and reconnecting those little connectors, but this is an entry level device. If you are going to do a lot of rotary engraving, you’ll leave it connected longer or maybe move to a higher level device.
Positioning the rotary, so it sits correctly under the laser is interesting. My laser sits on a board, which has the Lightburn grid engraved on it. So, I can get things situated nicely. Of course, you use the dowel piece to set the correct height for focus. Pay attention to how you set the head for Y-Axis. Framing is just going to rotate the subject piece under the head. Homing spins the rotary and sets the X-Axis back to the right.
You adjust the rotary device, for the size of the piece you are engraving, by moving one roller from slot to slot. You must loosen the motor belt to do this. Because the belt length is too short, you cannot use the slot for the smallest diameter. Thus, the smallest diameter I was able to engrave was about 1-1/4 inch. To be fair, a longer belt would prevent it from getting tight enough for the other slots. The belt is removable, so it would be nice if Acmer offered a little longer belt to accommodate that additional slot. That way, one could engrave things such as turned pen blanks or small tool/utility handles.
I have nothing, right now, that’s round for engraving. I do wood turning and may have some vessels that would look good with laser engraving, so I’m looking into that. I do turn wooden travel mugs that could be personalized with the laser.
Note about the riser legs – They only raise the laser an extra 17mm (about ¾ inch). Acmer sells additional leg bottom sections which are 45mm (about 1-3/4 inch) in length. Since the wood bowls I turn can be 3 – 10 i...
