Just got an Ortur Laser Master 2, bought LightBurn and am having issues with it. At first it would cut fine but now I’m getting an Alarm 2 at or near Line 4. I’m not sure what Line 4 is so I can’t determine what is out of bounds. It homes fine, but won’t stream. I then thought it might be the firmware because the first time I added the laser, the software added it as GRBL. When I deleted it and tried to readd it to fix the problem, it said the GRBL needed was the previous version. 1.1 or something. So I went to the forum about updating the firmware, followed the directions and it won’t let me copy the OLF_000.bin over to the laser.
Putting this in console:
In the console window, type:
G10 L2 P1 X0 Y0
It’s in absolute coords. It’s giving alarm 9 now. The ortur is homing forward and to the right instead of forward and to the left like it should. I’m still getting alarm 2 near line 4.
The $23 setting needs to be flipped - If it’s odd right now, make it even by subtracting one. If it’s an even number, make it odd by adding one. That is toggling the bit that controls the X direction.
In the LightBurn machine settings (0.9.15) these are properly broken out into individual flags you can just flip with a switch.

$1=50
$2=0

@PlaneAndSimple have you firmware updated your machine
If direction of homing is wrong on stock settings, it might mean you applied a wrong firmware to the machine.
In fact by your $$ settings you can see you have 150x160 max travle set
Please let me know so we can arrange a firmware fix for you because clearly your firmware is incorrect for your machine.
I used MAC. Had trouble updating it so then I used Windows and had to go through hell to reset with the 0.0 file and then reinstall the updated firmware.
I updated it because I was having the alarm 2, line 4 errors. According to other posts on this forum, updating the firmware for the ortur was recommended.
Looks to me the firmware is 1.34
Alarm 2 tend to be wrong job origin.machine “thinks” it will hit the frame so triggers soft limits
besides that.
the problem it seems to me is you have a OLM2 400x430 and you firmware updated it with OLM machine firmware, which is 160x150
So for SURE you will have problems.
Any way you can contact me directly (Gil Araújo) on our Ortur User Group in facebook, we need to firmware update it propper. But you will need a WIndows machine for that purpuse
