Hello there,
I am completely new to laser engraving.
I got the TTS 55 Pro since some days.
Unfortunately the laser stops working after receiving this:
“Guru Meditation Error: Core 1 panic’ed (Unhandled debug exception). Debug exception reason: Stack canary watchpoint triggered (LED task)”
I tried to google, but can’t find answers to it.
I hope somebody can help me.
Thanks a lot,
Sven
Not familiar with TTS 55 Pro firmwre but try
a) $RST=* in console to make sure you are in defaults
b) Update firmware if necessary
c) Make SURE you are using GRBL controller instead of GRBL LPC or M3
d) Make sure you do not have gcode cluster enabled
This said, that error is a kernel error sort of thing so the controller software itself is crashing, seems firmware related
See if your firmware and the latest at their page match
Thanks for your answer.
Everything should work fine.
But I still receive following message from the console:
Guru Meditation Error: Core 1 panic’ed (Unhandled debug exception).
Debug exception reason: Stack canary watchpoint triggered (LED task)

Does that help any further?
I wouldnt be able to help much more but maybe someone else can
I would advise taking that same data and contact the manufacturer i am pretty sure they might have seen it before and have a direct solution
To me is a firmware issue and as it says in the debugger is crashing the firmware kernel kinda thing. Why i wouldnt know
