I noticed some people complaining about the LaserCut english translations, you can open the language.ini file in notepad.exe and edit them as you wish. Just don't make them much longer from the original verisons if you can. I prefer Home / Z Home over Datum in the GUI for instance.
You can also edit the menus etc in Resource Hacker, it's pretty straightforward.
also if you screw up, just run lasercut53 and do ctrl+j create language file after selecting english., or use a backup of the .ini!
