programming for y-rail lengthening

[Chamy34 (CHAMAYOU)]

Bonsoir, I’m French, bad at English, so I use a translator.
I’ve just bought a Sculpfun S30 Pro Max.
Being an aeromodeller, I want to cut balsa or plywood into 1m boards.
So I’ve fitted the 935mm Y-rail extensions (which only give 900m of useful cutting).
I’ve made sure that the new dimensions are 370mm X 900mm, but to exceed 400mm of Y travel I had to deactivate soft limits and hard limits.
But when I do an autoguider home, the laser stops its movement as soon as 400mm has been reached and displays:
ALARM:9
Self-guidance failure. Unable to find limit switch at search distance. Defined as 1.5* max_travel during search and 5* during localization phases.

I’m new to Lightburn and haven’t mastered $ GRBL.

Thank you for your help.

You have to change your laser GRBL setting $131
and follow this guide

Sculpfun Extension Kit setup and settings

Thank you very much, it was exactly that.

However, for my instruction, how do I access the GRBL setting ($…) as in your image?

Best regards.

In Lightburn Console Window type $$ enter

.
But you have it defined, did you click Écrire?

[Chamy34 (CHAMAYOU)]

yes, I did define and select write.
All is perfect now.

But I am curious.
My request was: how to reach this setting listing? This GRBL setting?

Regards

That one is from LaserGRBL.

Per @parsec, you would go to the console window in Lightburn and enter $$ enter to get the equivalent information if I’m understanding your question.

[Chamy34 (CHAMAYOU)]

Bonjour
I typed $$ in the console input window, but nothing happens. I can’t see all the $ settings.

Maybe you can only access them with LaserGRBL?

I only know how to access this window.

If you move the slider up you can see the rest of the Console output.
