Good morning,
I recently started using the custom Gcode version of Lightburn.
I’ve encountered some problems…
I wanted to bring this issue to your attention:
I set the activation of tool 1 with the M3 S{*power} command.
The activation of the second tool with the M4 S{*power} command.
The problem is that power points to the power set on the first tool!!
Is it possible to have a command that points to the power set on tool two? For example:
M4 S{*power2}!
Is it already possible to do this? I haven’t found any documentation on this…
Thanks in advance for your support.
Regards
I see what you mean, and I’ll look into it.
I am curious though about the need to have S{power} be put on the same line as the M3/M4 though, as normally the power is part of the Cut Move.
Hi,
Thanks for your support…
Maybe it’s my fault; I still don’t fully understand how everything works, but I think there are some anomalies and differences in the code generation compared to the “normal” version. This morning, if I generated two simple squares, one with tool 1 and the other with tool 2, the power S wasn’t set for the second one… so I added M4 S{*power}. And I noticed that S{*power} was pointing to the power set for tool 1.
Now I may have solved it, but I’m still unsure!
They are two simple squares, the first with tool 1 (cutting), the second with tool 2 (engraving only).
As you’ll see (following your advice), I added a servo control that closes the valve that regulates the air flow. The M8 control turns on the air compressor.
Now it seems to work even without setting S{*power} for the second tool!
Do you have any suggestions? Did I set something wrong?

I would need to run some tests on my side, as I haven’t personally used variables in the Gcode profile yet.
Noticed one thing though:
You are using an older Pre Release version, but 2.0.04 has officially launched.
Please see if the latest full release behaves differently:
(In case your license key expired for free updates, you can temporarily deactivate it under “Help > License Management” and reactivate the free trial.)
Just ignore that second ‘Max Power(%)’ edit box and only use the first one. (I don’t think it is supposed to be showing).
And you shouldn’t need to include the “Sxxxxx” after the M3 or M4 for “Tool On”, since the power value only needs to be used in the ‘Cut Move’ area.
Good morning.
Thanks for your help!
I’ll definitely continue testing and using the custom version.
So I’ll try following your advice and see what happens!
I’ve also noticed other strange behaviors, checking “automatic instrument status,” “variable laser power,” and other things. I’ll run more tests and update you if necessary!
Ciao
Hi,
I also downloaded the latest version…
Here’s the problem I was telling you about!!
As you can see, two simple squares: the first for cutting, the second for engraving only! It seems to be pointing to the power set on tool 1!!

As you can see here:

G1 X158.5S500 F2000
At the moment I can solve it by putting the same power on both boxes (P1 & P2)… But I think there is a problem to solve!
I wanted to show you this too…as you can see from the pictures, I made a red box and you can clearly see that it points to the tool 1 power! I hadn’t noticed before!
Good morning,
I’m continuing to use the custom version… and I have to say that there are several problems, “bugs,” or anomalies regarding the code and other issues… I’ve worked around some of them by adding commands in the various dedicated sections, but that’s not a good or proper solution.
There is also a problem with the tabs and also with the layer settings that magically change by themselves and reset to tool 1, even if I save tool 2 as default…
I wanted to ask if you have any updates on this matter, or if I should report this in a more specific place. I’m available as a tester if you need me?
Thank you
Greetings
