Laser moves diagonal after every cut

I just installed the latest update. I did not change any setting from the previous version. Now after every cut, every engraving the laser moves diagonal towards bottom left for about 15 mm… 2 secs, (sometimes up to 6 seconds travel before it goes back to burning). When engraving 200 + lines I loose 400 seconds of work time. Just annoyed at this useless move which was not there before. Any idea what the cause can be? Made a clip but can’t upload it here.
Now a simple 1.5 min project to engrave takes me 15 minutes.

thanks

Also, Using current position as a start, I frame the work which is perfect, I start the project and it sometimes just runs out of bounds or flys away across the board.

Can I revert to old version easy??

Sorry better at woodworking than running the machine and figuring out the why’s of electronics

Yes, please see:

I can second this, I had the same effect. Though for me, the laser moved fully to the front-left, touching the limit switches and crashing the job due to the hard limits. I even exported the gcode files and the commands to move front-left are included there.
I did a clean install and the issue was solved (I think, I have to check again). I remove the LB preferences folder before installing again.

Thanks misken I will give it a try. Although I run on Mac IOS and I have no clue where the preference folder is..

Found it. wish me luck hehe

Before nuking the preferences, remember you can export your config as a bundle to back it up if you wanted to go back to an older version…

Thanks, should have done that before updating, although every time Updated before all my setting were as the last version. Thought this time would be the same. They seemed the same so either bug in program or something happened that I am not aware of.

Likely not - but after you open with the new version, you get defaults for the new values that may interfere with older versions. Normally it shouldn’t, but you never know. Better safe than sorry when it comes to a working configuration is my motto.

If problem still there after re install, what would I need to post here to help out figure what happened

Can you confirm this went away when you re-created your LB config from scratch in 2.0?
Do you still happen to have your previous config available, so I can try and fix the upgrade path that added these unwanted moves?

to be honest I am not the best at programming. I found the pref folder and copied it to my desktop then deleted from the original folder and just re-installed. So all I have in the backup folder are the files I copied as I didn’t know about the config export. I will fire up LB and see what is in there.
I will paste the $$ here if that is what you mean or need?

ok I am not sure what happened here but this is all I get from $$ request

Ah, if you don’t feel comfortable doing extra steps, I’m happy if the fix was to just re-create the preferences folder.

If there’s nothing specifically private in it, we would appreciate a copy of it (you can email it to support@lightburnsoftware.com if you don’t want the whole world to have access to it), and if you can include your current preferences bundle (File->Bundles->export bundle) that would also be appreciated.

No worries, I can do the extra steps and don’t mind showing the world lol… let me see if I can find

Ah, ok. So you’re using a GRBL device, and you sent the $$ before the connection was active.

Please try enabling this, in device settings → gcode tab → Fetch Settings on Connect


It will output your device settings and also let LightBurn parse a number of helpful values.

ooooh, that’s interesting. I didn’t notice before that your G54 workpiece offset is set to somewhere odd on your machine…

That could affect things with LightBurn 2.0. If you home your machine, can you send a ? in the command line and parse the output back here?

and that is with a Skapeoko 3XL paired with Tech 64watt diode

?

ok

How curious. You’re using a laser diode on the Shapeoko XL, is that right?

yup that is correct
