I don’t believe it will affect your engraving or cutting using the original nozzle or the air pump nozzle. However, when using the nozzle with an air assist, you should replace the power adapter that came with the air assist accessories. The 60 W adapter cannot handle the power if you are operating your iEngrave with an air assist. You may need to contact support to send you the appropriate adapter with your air assist.
On the other hand, have you tried operating your laser using the IdeaStudio on your desktop? You might want to try it first to determine if this is a software issue or the unit itself. In addition, the SD card should be inserted in the SD slot in your machine all the time.
You mentioned “update to the current version…” update what to the current version? I just set mine up two days ago (Saturday before Easter 2026), and it has also only ever beeped 3 times from the first time I turned the power on. It’s frustrating, to say the least. Thank you in advance for your help.
When I first got my iEngrave and powered it on, it always gave me 3 beeps. That went on for months, and it turns out that’s completely normal for the cover edition. HTVRONT/LOKLiK never mentioned this anywhere, so I shared it with the community based on my own hands‑on experience.
After updating to the latest firmware, my machine now gives only 1 beep when turning on (which I stated earlier on this thread). If you want to check whether you’re on the current firmware version, just go to Device Settings and tap it—like in the screenshot below.
On the other hand, if you’re using LightBurn, make sure your unit settings match the ones in the LOKLiK IS app. For example, your speed should be set to mm/min so everything lines up correctly.
NOTE: You only need to enter the same parameters shown in the Material Settings section under Material Management.
