LightBurn 2.2.01 Patch Fixes Crashes and Expands EZCad3 Galvo Support
LightBurn's first patch for version 2.2 focuses on stability and on EZCad3-based UV, fiber and other galvo lasers, with a handful of fixes for xTool, Creality Falcon and camera users.
LightBurn released version 2.2.01 on November 2. It’s a patch for 2.2 rather than a feature release, and most of the work targets stability and machines that use EZCad3 controllers, which covers many UV, YAG, CO2 and fiber galvo lasers.
What’s fixed
- Crashes and startup problems. The patch addresses LightBurn failing to start on some Windows PCs with Smart App Control turned on, crashes when importing CMYK JPEG images, and crashes on xTool, Creality Falcon and Duet machines if LightBurn is closed while a job is uploading.
- Cameras. Fixes cover camera previews freezing after a reconnect and a crash in the alignment wizard. The head-camera alignment check now zooms in on the camera’s view, and supported machines get a Continuous Jog toggle in the alignment wizard.
- EZCad3 galvo lasers. A long list of fixes covers false alarms, jobs that wouldn’t start, missing pulse and frequency commands, wrong scanner ranges on 18- and 20-bit galvos, and config files that failed to import.
Other changes
The Help menu’s Report a Problem option can now also be used to suggest a feature or ask for troubleshooting help, and bug reports can include your open project. Network discovery and galvo framing were added for Accelaser machines.
Should you update?
If you’ve had crashes in 2.2.00, or you run an EZCad3-based galvo, this is worth installing. One open issue to know about: one forum user has reported slower rotary jobs on two ComMarker Omni machines since moving to 2.2. LightBurn staff replied on October 23 that they were investigating, and this patch’s notes don’t mention a fix for it.
Version 2.2.01 is available from LightBurn’s download page.
