I have a 10W laser. The flame sensor alarm went off about 3 minutes into a burn. I plugged in $30=0 in the console window. I restarted the burn and now it randomly stops in the middle of the burn. The timer in Lightburn is still counting as if the laser was still burning but nothing moves. I don’t see any alarms. Is there a way to run any kind of diagnostics on the machine?
Are you on fill or line mode?
Are you engraving a object (svg) or an image?
Do you have overscan enabled?
Is your object near the edge of the workspace?
Posting a screen shot of your preview page and your cuts and layers window and your workspace is really a time saver when you are asking us to diagnose a random issue.
It has stopped twice, once 3:15 into the burn, the second time was almost two hours into the burn. Both times was during a “fill” phase.
I’m burning a design i made in Lightburn (American Flag).
I have about 1/2" space around the entire work area.
I’m not sure about overscan, I don’t know where to turn it on, kinda new to this.
Double click in the cuts/layers window on the layer name (i.e. 00). Overscan in an option.
You can restart the burn and it should line up with the original…IF (big “if”) you don’t move the wood. A HOME command may help, too.
Go to Preview, drag the slider bar to make the laser replay go to the right moment in the burn, and press “start from here”.
Your speed is set at 6000. That is absurdly fast for a diode laser on a gantry.
The overscan setting helps the laser have to be to up to speed before engaging and for it to have space to decelerate before changing direction. The speedometer on my computer car goes to 140mph. That will never happen unless it gets driven off a cliff. Maximum THEORETICAL ability is vastly different than practical ability.
Overscan is shown on your preview page by the red smudge outline around your project. That shows where the laser head travels, while the black shows where the laser is turned on.
I bet your problem is the laser head is traveling past the boundary of the workspace due to speed and overscan.
Make your project smaller by 10%
Make your speed around 3000 mm/min
Try again. I like to use recycled cardboard for my rough drafting. It does not take much power, so be careful not to burn it up or leave a smoldering fire.
Amazon boxes (who has those?) make great donors for material.
If this is a GRBL controller, that parameter number cannot be correct. It should be $30=1000.
