USB connection

Hi everybody, so I’ve been using my Iengrave before Christmas with no problem. yesterday when I went to use my iron engrave and connect it to my printer to make a dog tag, it’s now telling me that it can’t connect to my USB.

“ No device avaliable. Please research or check the USB connection.”
Can somebody please help me fix this problem?
I have tried uninstalling and reinstalling the software. I have tried turning it off and turning it back on after a minute I have tried taking off the Wi-Fi adapter on the side and re-putting that in. I have rebooted my laptop numerous times. And it still will not connect to my engraver. I have attached a picture of my problem.

Hello, @handmadebykathy1. :wave::smiley: Welcome to the community! Just to clarify, you are trying to connect via USB cord, am I correct? And not Bluetooth? Do you have the cord plugged into the machine? Or are you trying to connect wirelessly?

Yes, I am trying to connect via USB with the cord.
I have been using it with no problem up until yesterday. Now it’s not recognizing the cord for some reason.
I’m not able to do it wirelessly as I don’t have 2.4 Wi-Fi

Ok, I just wanted to make sure you definitely had the cord attached.

Check this comment for a probable fix:

Please, let me know if this works for you. If not, we’ll try something else.

I don’t know how to use laser GRBL. I am trying to use the LOKLIK app on my Windows computer.

If that doesn’t work, it could be any of these:

A Loklik iEngrave not recognizing a USB cord usually stems from driver issues, a faulty cable/port, outdated software/firmware, or incorrect software settings (like wrong COM port or needing manual driver install in LaserGRBL); power cycling the machine and checking physical connections are key first steps, but drivers are often the culprit, especially on Windows.

Common Causes & Solutions:

  1. Driver Problems:
  1. Physical Connection Issues:
  • Try a Different Cable/Port: USB cables can be finicky; try a new one and a different USB port on your computer.
  • Check Connections: Ensure the cable is securely plugged into both the iEngrave and the computer.
  1. Software & Firmware Mismatches:
  • Updates: Make sure your LOKLiK IdeaStudio app, LightBurn, and the iEngrave’s firmware are all fully up-to-date, as mismatches cause errors.
  • Software Settings: In LightBurn or LaserGRBL, ensure the correct COM port is selected for the device.
  1. Power Cycle:
  • Turn off the machine, unplug it for about 30 seconds, then plug it back in and restart.
  1. Specific Software Bugs:
  • LightBurn: Some versions (e.g., after 1.7.07) might have bugs; try dragging the .lbdev file directly into LightBurn or manually typing the device name.

Troubleshooting Steps:

  1. Power Cycle: Unplug, wait, replug, restart software.
  2. Inspect Cable/Ports: Swap for a new cable, different port.
  3. Install Drivers: Use software’s built-in driver installer if needed.
  4. Check Software Settings: Verify COM port and device profile.
  5. Update Everything: Firmware and software.
  6. Test with Simple File: Use a basic square to rule out design issues.

I’m using the LOKLIK app on my desktop.
I am not able to connect the engraver to the app on my phone. I don’t know how to use light burn or laser GRBL. My engraver doesn’t connect to any of those.

Is there a way to reset my engraver to factory settings?

Ok, I’ve included instructions for Windows & Mac computers. I’m not sure, as I don’t have the iEngrave, but I think you need LightBurn or something similar in order for it to work, according to what I’ve seen in the community. However, we should let @rinsky or @Cory_Barger confirm. They will be better at answering these questions. I just wanted to provide you with the information that I know. Please, allow them time to respond. :heart:

Ok, I’m not sure why it’s not working for you. Like I said, let’s let @rinsky see if she can give you anymore information. Please, don’t worry. If the machine doesn’t want to work for you, after trying all troubleshooting techniques, you can contact support@htvront.com, and they will either fix the machine or send you a new one. @Rinsky is pretty good at troubleshooting the iEngrave issues, so if she can’t find a fix, support will definitely help you get this resolved. :heart:

Hi and welcome to the community @handmadebykathy1! I’m sorry you’re running into this issue. From my experience as a user, this is actually pretty common. When the iEngrave isn’t used for a while, it tends to go into a “sleep” state, which can look like a connection problem. In situations like this, you usually don’t need to uninstall or reinstall the driver. You just need to reconnect the machine the same way you did the very first time — this applies to mobile users as well.

I also want to thank @Nat_Wen and @Samantha_Bryant for jumping in with support.
Now, let’s walk through some steps to get your iEngrave talking to your computer again. Since you’ve already reinstalled the driver correctly, here’s the process I personally follow (and I even powered mine on this morning to double‑check these steps for you):

• Start fresh: turn on your computer first, but don’t plug in the USB cable yet.

• Open the LOKLiK desktop app and add a text object as shown below. You’ll notice my iEngrave still isn’t connected at this point. Highlight the text and click Make.

• On the next screen, you’ll see the available connection types. At this point, power ON your laser — make sure the power switch is on, the safety keys & SD card are inserted, and the emergency stop is released.

Once the machine is fully on, connect your USB cable to both the laser and your computer. Select USB from the options, then click Next as shown below:

• Do not worry about the screen, take some time to connect through USB cable:

• Before connecting, use the arrows to review each requirement and confirm everything is met. Once all items are checked, click the Search button as shown below:

• Then you’ll see it in your screen that your iEngrave is active then hit the connect:

• When you return to your canvas, you should now see that your laser is successfully connected to your computer.

If you’ve followed all the steps above, you should be on the right track. If not, go back through each step and double‑check your process to make sure nothing was missed. Wishing you the best, and please keep us updated!

This didn’t work. Still saying No device available. Please research or check the USB connection

That is strange. Did you double‑check the USB ports on both devices to make sure the connection is secure and not loose? You might also want to try a different USB cable to rule out any hardware issues.

If you’re unable to connect through the USB cable, try connecting through the LOKLiK mobile app to help narrow down the issue. Here’s a link for reference only:

Yes I have. I tried 3 different usb cables. And it still wont connect.

Is there a way to do a factory rest on the machine.

There’s a reset button located between the USB port and the TF card slot on your iEngrave. When you press the reset button, make sure the USB cable is not plugged in. The iEngrave should be powered ON during the reset and pay attention to any beeps or movement from the laser head. I haven’t personally run into this issue, so I haven’t needed to use the reset button on my machine yet.
