I have read previous posts without successful resolution
Traversal lines are burning and unable to resolve.
I am running GRBL on Just Lasers 15000mW Laser Cutter And Engraver.
Macbook Pro running Monterey 12.0.1 (21A559)
Issue has occurred since software upgrade to LightBurn 1.0.06
Unsuccessful actions trialed
Updated software / restarts etc.
Toggled constant power mode in Cuts / Layers
Typing command line $32= in Console
Toggled on/off Enable Laser Mode in Device Settings
S Value is set at 1,000 MAX in Device Settings (though I don’t fully understand this and the correlation controller power) and have attempted lower settings (but burn and traversal both adjust vs prevention of burning traversal).
Hi there, this is an existing set up that has been working prior to software update ie. traversal lines have been burning only since update.
When opening a file and selecting device Console displays:
Grbl 1.0b [’$’ for help]
Your GRBL may not support Variable Power Mode (M4).
If your laser does not turn off between cuts, switch to the GRBL-M3 device.
I can/have manually created the GRBL-M3 device.
Issue then is that I cannot connect to this device.
I can only maintain a connection with the GRBL set-up (which causes the traversal issue)
I am using USB connection.
I have been experimenting further and have managed to gain a connection with GRBBL-M3 device on Macbook Pro. Seems a bug if there is more than one device profile set-up in LightBurn.
A continued (intermittent) issue is that connection is not persistent; ie. I have needed to do a system and hardware reboot on a few occasions as I receive a ‘disconnected’ device status that cannot be resolved when changing to a new file. I cannot always replicate this issue / not consistent.
Full reboot and recreation of device profile seems to resolve but is annoying to have to do this.
On updating I was unable at all to connect to this, and could only connect with GRBL (with the transversal issues). I have subsequently updated the Mac OS to Monterey 12.01.
I am currently running GRBL-M3 (1.1 or earlier).
I tend to think this has nothing to do with the LightBurn version. You should downgrade to confirm. You may want to hunt down all LightBurn preferences and also delete them. Not sure about the location on Mac but File->Open prefs folder should reveal it.
