Alarm sound after update

  • Just updated the firmware to latest and laserweb is latest version. All work great except one thing. After a job is finished, the laser head homes as normal but then emits a solid (doesn’t stop until unit is turned off) constant alarm sounds, not the  usual few beeps when job is finished. any ideas, tried a few jobs all had same result, had to power off em2 to shut off alarm.

Hi Cameron,

I had the same problem. Domenic tipped me off to the solution here:

You just have to change the last line of all your existing gcode files which you use to the updated homing command:

“M911G4P0.5M912G4P0.1M911G4P0.1M912G4P0.05M911G4P0.1M912” (without quotation marks)

That is, replace the existing last line with that one. I used notepad++ to edit the gcode but you can use any kind of basic text editor.

Hi Jeremy, It happens on newly generated files, I am not using existing gcode files.

I see in the settings tab there is a Gcode area down the bottom see details below but could I just paste and replace that code you have, to the Gcode end area

It has a

GCODE END

with this code in there
