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 lo…

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.

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 t…
