Hi and welcome to the community @Aadele_Sill!
Oh no, I’m so sorry you’re going through this—especially after all that effort and excitement. You’ve already done a ton of smart troubleshooting, so let’s build on that and see if we can get your Loklik iEngrave to finally engrave.
Here are a few things to double-check:
1. Material and Settings Match
Make sure the material you’re using is compatible with engraving mode—not just cutting—and that your settings (speed, power, and passes) are appropriate for engraving, not cutting or framing.
2. Firmware and Software Sync
Confirm that your firmware is up to date and that the software you’re using (Loklik IdeaStudio App or LightBurn, if applicable) is correctly recognizing the machine. Sometimes a mismatch can block engraving commands.
3. Laser Head Positioning
Even though you manually moved the laser head, double-check that it’s not too high or too low. Engraving requires precise focus distance—usually around 50mm depending on your lens.
4. Preview vs. Actual Job
If it frames but won’t engrave, check whether you’re accidentally running a “frame” or “preview” job instead of sending the actual engraving command. Some software separates those steps.
5. Emergency Stop or Safety Interlock
Look for any triggered safety features—like lid sensors, emergency stop buttons, or air assist interlocks—that might be preventing the laser from firing.
6. Test with a Simple File
Try sending a basic shape (like a small square or text) to engrave on scrap material. This helps isolate whether it’s a file issue or a machine issue.
You’re not alone—this machine has a learning curve, but once it’s dialed in, it can do amazing things. If you want, I can help walk through your settings or even review a screenshot of your setup. You deserve to feel that excitement again
