Hello everyone,
I am looking for definitive, clear, step-by-step guidance from anyone who has successfully integrated LightBurn with a Makera Carvera Air to run the laser module. My AI assistant completely failed, ran me in circles for days, and left my machine settings scrambled, so I need to reset my workflow with real human expertise.
Here is the exact description of my hardware, software, and setup:
• Machine: Makera Carvera Air (Kickstarter Campaign Edition). This model features the manual Lever-Based Quick Tool Changer, NOT the larger original Carvera with the 6-slot Automatic Tool Changer (ATC).
• Laser Module: Official 5W Integrated Laser Engraver Add-On.
• Active Workspace: 300 mm (X) × 200 mm (Y) × 130 mm (Z).
• Host Laptop: Acer Predator Helios Neo 16 running Windows 11.
• Software/Firmware Versions: Running Carvera Controller App v0.9.14 connected via USB (COM3) to the motherboard running flashed Firmware Version v1.0.7 (GRBL core framework).
• Active Fixture: A multi-slot 3D-printed card jig bolted to the bed grid, with the work piece positioned at the front-left corner quadrant (Anchor 1).
• Goal: Establish a reliable, repeatable process for engraving an anodized aluminum business card.
I need an expert to give me clear, step-by-step instructions for the following three areas:
1) How to correctly configure LightBurn for the Carvera Air:
- What should the exact Device Settings be (Width, Height, and Origin point location)?
- Which options under Z Control (Enable Z Axis, Relative Z Moves Only) need to be turned on or off?
- What "Start From" mode (Absolute Coords, User Origin, or Current Position) must be used in LightBurn to align natively with the Carvera Air's firmware spacing?
- How do I prevent LightBurn from outputting automatic tool changer macros like 'M6' that cause the Carvera firmware to trigger safety interlock pauses?
2) How to set up and configure the Carvera Controller App (v0.9.14):
- How do I correctly map the Work Coordinate System (WCS) for a front-left corner fixture (Anchor 1) so it coordinates properly with the file?
- How do I handle settings like "Scan Margin," "Auto Z Probe," and "Auto Leveling" in the "Config and Run" sidebar specifically for a laser project on this version of the app?
- How do I fully clear out cached coordinate offsets or tool changer pause buffers from the motherboard memory so I am starting fresh?
3) A simple roadmap of the exact interface steps to run the job:
- A walkthrough of exactly which buttons, tabs, icons, and terminal commands to click or use in the Carvera Controller dashboard to load the file, run a safe red-light perimeter trace to visually verify the card placement, and safely execute the laser engraving.
I want to completely understand the relationship between LightBurn's output and the Carvera Air's custom GRBL backend language so that I can safely run these projects without errors or frame collisions. If you have this exact configuration working, please share your workflow settings.
Thank you!
As far as I know, you’re the only customer that has this type of machine. It’s very unlikely that all the functions are available via Lightburn.
Try this thread and see if it helps. That said, I think you understand why I doubt anyone here could really answer all of your questions. Check the date of the post. MillMage might be more operational, but it’s really for machining with mills.
Good luck.

This might work, if the controller board supports lasers as well as spindles. My 3018 CNC machine had a GRBL board that allowed swapping out the spindle for a laser.

I’ve had this Carvera Air since the Kickstarter Campaign, with everything that could possibly come with and, and many extras that they threw in during the Campaign. I was in the first 500 to purchase the machine… unpacked it… then it sat on my bench as I was busy doing other stuff… and waiting till they sorted out all the glitches with the softwares, etc… I want to start using it, but using AI 
to get it up and running is impossible!! I don’t know if it’s me or AI … more me than AI to understand how it works. I’m more of a hands on type of person, or clear step by step instruction follower… once I start to understand something, then I kinda get it. 
I just need someone to come and make sure that everything is set up and configured correctly and to give me a few lessons with some basic projects to grasp the works of it. The videos on YouTube are either so outdated or not for my specific Carvera Air edition of machine.
You bought into what is called the Bleeding Edge of Technology. That makes you a Pioneer. It also means there will not be much support, that is specific to your machine.
Ask lots of questions, and surely someone will try to help you move forward. Experiment, then tell us what worked and what did not. If you encounter something with which you are not familiar, say so. The only dumb question is the one you did not ask.
