My name is Armin and I work part-time as a teacher in a middle school. The other half of my time is devoted to software development. The school just got an Atezr P20 (20W diode laser) and I'm trying to figure out what you can do with the thing.

Successful so far: you can write on or cut wood and cardboard beautifully cleanly. Beginner level (bloody): check.

Failed so far: even at full power, plastic (checkered types) only get a brownish contour melted, with minimal penetration into the material.

So far a resounding failure: metal. Someone had some small sections of copper and steel sheet left over. Even at full power there is no noticeable effect on the material.

Successfully labeled: the table top. I didn't pay attention to the question of how I could provide the machine with a repeatable zero point and got sidetracked with the material. Lesson learned: never engrave your name as a test, because now it is clearly visible on the tabletop as proof of my total failure

My first question: is there a tutorial where I can read how to engrave "difficult" materials, such as plastic credit cards and metal plates? I mean, there are coatings, maybe already coated material?

Thanks for your tips,

Armin

As for engraving "difficult" materials like plastic and metal, the Monport Laser may offer solutions. The link provides comprehensive information to guide you through the process. Happy crafting!

Hello everyone,

I have an Atomstack A5 20W. I've had this for a while now, but I've only been using it (or want to use it now) more intensively since I got an enclosure with exhaust air. Engraving works okay, I'm still working on the settings. However, I just can't get any further with cutting. However, I suspect that there is a more fundamental problem than just the settings (I use Lightburn), as the cut on the Y axis doesn't seem to be wrong, but on the X axis it seems to be a disaster. The wood burns, but absolutely does not cut through. It doesn't matter what I set, how many passes and so on.

Here's a picture, I think the setting was 80% at 100 and one pass. As you can see, the cut from top to bottom is much finer and also through, the one from left to right is charred and not through. What else can I do there?

I cleaned the lens, but I think it's something to do with the settings or the hardware? And it doesn't matter how I lay the wood, i.e. with or across the grain. So the problem seems to be somewhere along the axis? Maybe someone has already had experience with this and can help me?

Hello everyone,

I need your help

I've been having problems with the Omtech 1060 with 100 W tube since yesterday. It no longer has any power, the mirror, focus, etc. everything is fine, I checked a few weeks ago and haven't lasered much since then. I'm in contact with the VK, I was supposed to make various videos, I noticed that the laser beam at the output was jumping back and forth a lot, the material test was just running in Lightburn.

Here is the video https://www.youtube.com/shorts/UmpF982xUow

I should also do a test and test shots with 45% power, the digital display only shows 3-4mA, which was otherwise always 14mA at 45%.

Is the power supply or the tube dead?

Thank you and have a nice WE

I'm sorry to hear about the issues you're facing with your Omtech 1060 laser cutter. Based on the symptoms you've described, it could potentially be a problem with either the power supply or the laser tube.

Best of luck with resolving the issue, and I hope you have a great day!
