I am still learning, so, I have had to stop a few test burns.
After I manually hit stop, I hit the HOME button and change out the material for a fresh one.
If I start the job again, the laset head moves to the starting point, then just stays there and the laser blinks as if it is pulsing at the right pace, but the X-axis is not moving. So, it just burns a hole.
Is there a better sequence of steps to reset everything after a manual STOP?
Exiting LightBurn and restarting seems to work, but it seems like there might be a better way.
Thanks and stay safe!
Did you hit the Stop button in LightBurn itself? The behavior you’re describing is unusual - I haven’t seen that before. Which specific Ortur do you have? There might be a firmware update to fix that.
I do know that the v1.40 of the firmware for OLM2 had an explicit fix for pause/resume behavior. I don’t know if this is the same mechanism used in STOP. v1.42 was recently released as well so worth upgrading if you haven’t yet done so.
Ortur Laser Master Firmware
V1.40
Release Date: 04 January 2021Fixes:
-Pause/Resume issue been corrected. Laser Pause/Resume functions now work as expected;
-Corrected False positive [Check Limits] on Pro Motherboards (RJ connector/Vertical buttons boards);
Improvements
- GRBL Core Upgrade from 1.1f to 1.1h;
- Optimization of USB Driver Library. Attempt to address disconect issues/Alarm 3;
- Fan Delay ShutDown Function. Fan will Remain on from 30 to 120 seconds, based upon the length of time and maximum power of the just finished engraving.
- G-Shock Sensor Algorithm. New algorithm reduces the amount of false positives;
Yes, I hit the STOP button in LightBurn.

I thought that I was missing a step to reset things after hitting the STOP button in the software.
The way around it for me was to just quit and restart LightBurn. I stumbled through the projects that I needed for today (last minute gifts).
After tomorrow, I will take a closer look at the problem, unless there is a firmware that I can try first.
Thanks everyone for your prompt help.
You’re on the newest firmware for your model.
I’ve never had great luck running a job following a failed job or unplanned stop. I typically need to reset and restart my laser to recover. I don’t know if this is considered best practice, however.
Hi,
I found a similar problem right now.
I have a SculpFun S10 laser cutter/engraver (on Win10/64) and I have used LaserGRBL with this machine so far. I would like to switch to LightBurn (v1.4.05, during test period) and am testing it right now so, I am newbie in operating LightBurn of course.
Now I found a problem: after several successful jobs, in case of the latest project, pushing the Stop button on the screen during cutting job, I interrupted cutting operation. It was okay, the cutter head stopped, the laser light was out but the machine does not move afterwards. No homing, no manual moving. Even more, no matter how I restart the laser cutter or my PC, still not moving. This is strange because I did not change any parameter or adjustment in LightBurn.
But, at the same time, LaserGRBL can communicate and control the machine flawlessly, since that time as well. This means, probably, not the machine is sick.
What can be the problem? This is very important because I cannot use the software at the moment…
Should I reinstall the software???
Thanks in advance,
Attila
Make sure that you have the correct serial port selected in Laser window.
Thanks for your prompt reply!
This was one of the first things to check. As I wrote: nothing has changed.
(And I can use the machine with LaserGRBL via the same port now.)
Update:
I found very strange characters in the Console window (I have never seen these before):

Review the baud rate setting in Edit->Device Settings. I believe your machine should be configured to 115,200.
Thanks the tip, but the baud rate is exactly the value what you proposed.
The error phenomenon is that since I stopped the machine once during cutting by pressing the stop button, the laser cutting machine and the PC have not been able to establish a connection since then.
But:
1. before the error above appeared, I did several jobs and finished them with LightBurn without any problems, so it worked well.
2. I haven’t changed anything in the software since the error occurred
3. the LaserGRBL software can still connect to the machine and I can cut with it, even this moment.
I have just deleted the SculpFun S10 from devices of LightBurn to reconnect it, but the PC cannot find it again.
But with LaserGRBL it works smoothly, even now!!!
This must be an internal software bug in LightBurn, I’m almost sure because, as I wrote, one single parameter has not been changed!
My question is: since I’m using a trial version of LightBurn (and it’s only been two days), can I delete and reinstall the program without losing the trial period?
I’d give this opportunity a try before I forget about this unreliable LightBurn app, even though I really like it, and wanted to buy…
In Edit->Device Settings, enable “Enable DTR Signal”. Does that change the behavior?
