Guru meditation error after homing Sculpfun S10

[4ctive (Ben)]

I got the following output in the console after homing my Sculpfun S10:

Guru Meditation Error: Core 1 panic’ed (LoadProhibited). Exception was unhandled.

There is nothing that went wrong or any other problems. After homing is completed the laser sets its position to 0, 0 and waits for input. So I just noticed this output in the console window and was wondering if there is something wrong.

I’m not a Mac person, but don’t know what Guru Meditation is used for in relation to Lightburn ?

@4ctive

noticed this output in the console window

In Lightburn … ?

Yes in Lightburn. Sorry, forgot to mention that

[jkwilborn (Jack Wilborn)]

I don’t recognize the name of the software that failed on you. It sounds like the firmware on your laser is telling you this…

Doubt there is any fault with Lightburn, I’d check with Sculpfun…

Maybe @JohnJohn has seen this before…

Hang in there…

John should be relaxing so we can start beating him up again on Monday …

[4ctive (Ben)]

Monday is totally fine
I also reached out to Sculpfun and will report if I get something from them.

Guru Meditation Error:

Guru Meditation Error is shorthand for one of the dual core 32 bit microcontroller cores crashing.

The xTool was infamous with this issue, if the write protect switch was on.

@4ctive

Core 1 panic’ed (LoadProhibited)

The Console window only tells the truth and relays messages back and forth.
LightBurn is behaving as expected. The S10 is a vivid shade of confused.

If you were homing, that should have been allowed and shouldn’t have been too data-rich. Have a look for a write protect or write enable switch on the edge of the control board of the S10. If the engraver was expecting a minor amount of settings data and got a homing sequence that could do it.

Are there Limit switches waiting for a nudge from the laser head when it arrives home on your S10? The head should be homing toward switches. if it’s not, you have to add or move switches, change homing behavior or have current sensing motors.

Please enter $$ in the Console in LightBurn and copy and paste that report into a reply here. Hopefully we’ll see something weird in the settings contributing to this.

I will have a look for the write protect. Thanks for that info.
As I said, the coming works all well and after the homing, the laser is at position 0,0. The head is homing towards the right direction for both axles and is touching the switches twice (first time with more speed, then the second time very slowly), I think thats how its meant to be.

This problem is a known bug in the original S10 firmware. The homing function is not implemented correctly. After homing, the firmware crashes and reboots. Fortunately, this has the effect that the position is reset to 0,0. So, no issue in operation. If you don’t like this behavior, flash a new firmware (the one that is provided here is fixed: Firmware Update & Settings - Diode Laser Wiki

Thank you very much. I got the same answer from the Sculpfun support.
I did update my firmware yesterday (I chose the one provided from Sculpfun itself). Everything is fine now, as you said.
