Good idea! I guess, you have a case too?
Maybe you should fix the screw with a threadlcoker (Schraubenfix).
Is there any gCode to control the sensivity? Or do I have to adjust the flame detector sensivity in Luban , save it and then I can use the latest preferenceses in LightBurn?
I would assume adjust the sensitivity in Luban and it should remain stored as a setting. I donāt actually have a 20/40W laser or the Ray. Theyāre terribly expensive and I just canāt budget that in. 
So I can only try helping where I can with experience/knowledge of other setups. It does make it hard to help others without actual access to the hardware.
fyi:
I have added the control information for the Flame Detector into my wiki.
M2002 T5 PXX
And I have verified that the Power Mode output gcode for the 40W from Luban to SM 2.0.
M2000 L23 P0
M2000 L23 P1
I think I see the discrepancy. The photo you posted of the 40W module does not have the module adapter on it from the Quick Swap kit. Iām using the QS adapter from the kit so I think my module is mounted at a different height than yoursā¦
Hi Skreelink, can you point me to any SNAPMAKER or LUBAN information that will have more information about the flame/fire detection?
I got that error today, and google search led me to this postā¦ Youāre always full of good info, but I am wondering if there is some repository of glossary/lookup terms to educate myself.
thanks!
There isnāt much info outside of bright lights (such as a window with direct sunlight shining in) can set it off and I found a gcode to set sensitivity here;
Specifically for the Artisan, but it may work with the 2.0 (you didnāt say which machine you had)
M2000 L16 P10 I assume the P10 adjusts sensitivity matching up with what you can do on the touchscreen, Which I found here how to;
Settings > Maintenance > Laser Calibration Parameters > Fire Sensor Sensitivity

; !!!! If you agree and setup your settings then comment in the line M1999 below by a semicolon !!!
; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
; this will restart your machine as long as you do not admit
M1999
In the repository the above is listed and Iām being a little dense. Iām not sure what to do here? Do I comment this line āOUTā or āINā. The reason I ask is that it is already IN, so is this supposed to be commented out in the repository? What does M1999 actually do?
Still being dense, Iām trying to get my z-value. Following the link in your guide is odd. It has you lower to the work surface using the sensor, then if you have a quick swap, unlock the module and manually lower to surface. This makes absolutely no sense to me. Is there anyway you (or anyone else) can give me an easy way to obtain my z coordinates?
Last question from a complete noobā¦ I canāt get this running over a network so Iām just going to use the thumbdrive to get my job to the SM. Is there anything special I must do?
Appreciate your guide and hope someone can get me up and running. Thanks all!
Your first question is already answered by the header
; 1) see gcode reference guide for SnapMaker https://snapmaker.github.io/Documentation/gcode/G000-G001
It protects your head running into the bed, if you do not follow the calibration guides. Afterwards, you have the edit the values in the code corresponding your machine.
As a result:
- Calibration
- take over your own z value
- deactivate M1999 (Its a DAU-Stopper to protect user from damage ā English: dumbest assumable user German: DĆ¼mmster anzunehmender User
)
Btw, DAU is not you, as you did well by asking what to do.
Make your calibration as by SnapMakerās guidelines for your machine.
Afterwards, you can even read your z-Index from your machineās display.
BTW, what kind of laser have you mount?
re: Flame sensor
The latest firmware Snapmaker2_V1.19.0 now has the option to disable the flame sensor under laser settings.
" * Added disable option for 20W/40W Laser Fire Sensor Sensitivity
- Disable fire sensor sensitivity option will erase the sensitivity value"
Prior to that, I just covered it with a piece of pinched off heat shrink tubing.
Thank you for the quick reply.
Iām have the 40w mounted to a quick swap kit on an A350T machine. The value Iām getting is nowhere near yours, so Iām feeling a bit reluctant to even try it. Shouldnāt our Z values be at least close in value (assuming you didnāt modify your set up)?
I reread the calibration document and think I might have an idea on what I did wrong. Iāll try again.
Again thank you very much.
There are many different ways to mount the 40W module!
- without any quick snap on rail ā fixed with screws
- with quick snap on rail but nothing on 40W => a kind of luck to have same z- value
- with quick snap on rail : 40W with screws as shown above (a good idea, which I also practice)
- with quick snap on rail and with quick snap on module
- with the bracing kit, as far as I know

To disable, use this:
; Flame sensor off
M2002 T5 P4100
