Y’all, help me! I’m ready to put this thing back on the box and send it right on back. I’ve never had an issue figuring things out, but this laser is giving me the blues! Please watch the video and please tell me what I’ve done wrong!
Thank you so much in advance!
@rinsky Can you help them please.
@NiNi Have you had a look at this page to see if there’s anything that helps?
Hi @Nini! The issue you’re having usually happens when one of the limit switches isn’t being detected during startup. That’s why you’re getting the three beeps, the framing is reversed, and the machine vibrates instead of moving. The engraver basically doesn’t know where “home” is.
Here’s the fix:
Turn the machine off.
Gently slide the laser head all the way to the left and press the little limit switch with your finger. It should make a clear click.
Do the same for the top limit switch.
If either switch doesn’t click, or feels stuck, that’s the one causing the problem.
Clean around it, make sure nothing is blocking it, and make sure the head can physically reach it.
Turn the machine back on with the head pushed into the top‑left corner.
This forces a clean homing cycle so the machine can re‑establish its coordinates.
If the switch clicks but still isn’t being detected, the wiring to that switch may be loose.
Reseat the connector or gently press it in to make sure it’s fully connected.
Once the limit switch is working and the machine can detect home properly, the three‑beep startup, mirrored framing, wrong‑corner homing, and “Frame Failed” errors should all stop.
Let us know if this works for you, if not, we can move on to the next steps.
Thank you for this, but what’s the “limit switch” and “top limit switch?”
Thank you.
I’ve studied that thread like I’m studying for my nursing exams… I go back every now and again in case I’ve missed something.
No problem!
The limit switches are really small, so here’s exactly how to find them and what they look like:
• LEFT LIMIT SWITCH (far left side):
If you turn the machine off and slide the laser head all the way to the left, look right where the head would “bump” into the left rail.
You’ll see a tiny black rectangular switch with a little silver or black lever on it.
When the laser head touches that spot, that lever should click.
• TOP LIMIT SWITCH (very top rail):
Now slide the head all the way up toward the top.
Right where the head would “bump” into the top bar, you’ll see another small black switch just like the left one.
It also has a little lever that should click when the head reaches it.
They’re basically the machine’s “stop buttons.”
When the head touches them, the machine knows, “Okay, this is the top‑left corner — this is home.”
If either one doesn’t click, or the head can’t reach it cleanly, the machine gets confused about its position and that’s when you see the weird framing and drifting.
There is a whole lot of bumping, but no clicking. And I still don’t see any black switches. 
I don’t think I’m looking in the right place. I don’t even know if I’m in the general vicinity…
It’s totally okay that you’re not seeing anything — the limit switches on the iEngrave are really hidden. They’re not big buttons, and they’re not out in the open. Loklik tucked them inside the rail area, so you won’t see a big black switch sitting on the outside of the machine.
Here’s how to make sure you’re in the right spot:
• On the LEFT side:
Turn the machine off and gently slide the laser head all the way to the left.
Put your finger right where the head touches the left rail.
You won’t see the switch, but you should be able to feel a tiny click when the head presses into that corner.
It’s a very small internal switch, so it won’t look like a visible button.
• On the TOP side:
Slide the head all the way up toward the top rail.
Again, you won’t see a big switch, but you should feel a tiny click when the head reaches the very top.
If you’re not feeling any click at all, that usually means the head isn’t actually reaching the internal switch — either because it’s slightly misaligned or because the switch is stuck inside the rail.
You’re definitely in the right general area — the switches are just hidden inside the frame, not visible on the outside. So don’t worry, you’re not missing anything obvious.
Edit: Instead of a loud click, it’s more like a tiny soft tap.
Hi @NiNi! First, I’m really sorry you’re running into these issues.
Second, we’ll do everything we can to help you get this sorted out.
And third—this machine is actually a great choice for beginners, and I genuinely enjoy using mine!
@MCVDFC and @Samantha_Bryant, thank you for stepping in right away.
Okay, I just watched the video, and it does look very similar to what I’ve seen from other iEngrave users here. I could tell right away that the framing was way off, which explains the grinding noise. The good news in your case is that your laser module still returned to its set origin afterward.
Those limit switches on the X and Y axes are permanently installed by the manufacturer, and you generally don’t want to tamper with them. You can check to make sure they’re snug and properly seated, though.
Next, gently move the laser head by hand—left to right, then up and down—to confirm nothing is blocking the rails and no wires are getting caught. When you move it to the top‑left corner, push it firmly until it clicks or stops so it reaches its true home position.
After that, perform a hard reset: press and hold the reset button on the front of the machine for 30 seconds to a minute. Pay attention to what the machine does or sounds like during this process. Then turn the laser off, unplug the power cord, wait about two minutes, plug it back in, and power it on again. Connect as usual and run a simple test.
If none of that resolves the issue, it’s time to update your firmware to the latest version (see my earlier response for instructions.
Ok, I’ll step back, now. I was only trying to help walk through the basic checks since the symptoms matched a homing issue, but if @rinsky is guiding you now, that’s totally fine. I don’t want to confuse things by having too many voices at once. I hope it gets sorted out for you.
You don’t need to step back from this conversation, @Samantha_Bryant 
. I’m actually glad you jumped in when you did. I was asleep when our member needed help, and I only responded later because @MCVDFC tagged me. Your suggestion about checking the limit switches was really helpful and may have even solved the issue. I just wanted to remind @NiNi to be careful not to pull on those switches since they’re secured with that red permanent glue.
@NiNi, here are the limit switches (X‑, X+, Y‑, and Y+) for your visual reference.
Note: Please visually inspect your Y‑axis switch and make sure the connector is firmly seated by gently pressing it into place.
Thanks for the clarification, Rinsky. I wasn’t stepping back because I felt disrespected or anything — I just didn’t want to overwhelm her with too many different voices at once. It looks like she’s in good hands now, so I’ll let you continue guiding her.
Thank you both very much. So I was in the correct place, but I guess I was looking for a button or some sort of tiny toggle switch. I even put on my “I can see through walls” glasses to find the tiny switch! 
I might have to take the cover off and put my head in the machine, LOL, but I’mma figure it out! 
I did all of the reset steps. It didn’t do much but beep after I released the reset button. Would I need to reconnect it to the app or Lightburn? The app didn’t respond when I clicked on the connect to device button…
Yes, please! Re-connect your iEngrave and please use the LOKLiK IS desktop app version like you did earlier. Let us know your progress. Please use your USB connection this time. After reset, power off, power back ON and firmware updates (you need to restart your computer after updates performed), did your laser beeps 3x or a single beep?
Also, did you happen to manually adjust your laser module height or the focal pin at any point. Make sure to toggle OFF your air pump in the desktop app when you’re doing your framing.
I used the desktop version to reconnect (phone app was not feeling me at all). I did all of the things you told me. But nothing different is happening.
Oh, and there is now another issue:
Everytime the laser goes to that left position in the back… and starts that grinding noise…? A spring falls out from somewhere. I don’t know from where - if it’s from the bar or from the laser head itself, but springs are falling out! 
Three so far…
Okay, I’m going to step back in real quick… If springs are falling out when it homes, that means the gantry is physically crashing into the back because the Y‑axis switch isn’t being triggered. On the Loklik, the switch is a hidden board‑mounted module, so if the gantry stops short or the switch isn’t aligned, the machine will keep pushing until something gives. With the machine off, slide the gantry all the way back and see if it reaches a firm stop or gives a soft internal tick. If it doesn’t, the belt may have slipped, the rails may be uneven, or the switch module isn’t being hit.
Since springs are falling out and the machine is still grinding after the reset, that means the gantry is crashing into the back because the Y‑axis switch isn’t triggering. At that point it’s a mechanical failure inside the machine, not a software issue. Loklik will need to take care of this one — I’d reach out to support so they can repair or replace it. Send them the video you shared here, along with the pictures of the springs.
Send email to: support@loklik.com
Oh gosh… one member was able to fix this by pushing the laser head firmly back into the homing position, but others ended up returning their machines and getting replacements. Since yours is brand new, I’m afraid you may have received a faulty unit. It’s extremely rare—almost a one‑in‑a‑million situation—to see a spring fall out like that.
As @Samantha_Bryant mentioned, the best next step is to contact HTVRONT for a replacement. I’m really sorry I can’t help you further with this mechanical issue.
Don’t give up on owning one—it’s truly a great laser machine! We have tons of members sharing their creations in the Latest Inspiration topics - HTVRONT | LOKLiK Community , so feel free to check those out. I also have some YouTube videos - Erin Theige - YouTube you can watch for inspiration. Wishing you all the best!
Sorry you’re having so much trouble @NiNi. HTVRont/LOKLiK customer services are excellent and should help you get a resolution very soon.
Thank you @Samantha_Bryant & @rinsky for stepping in. I don’t have the iEngrave so have no experience of the machine (but I really, really want one!)
