Hello! I recently unboxed my Creality Falcon 2 40watt. I initially started with a TF card for the .gcode and just switched to using a 16FT usb-c cable to connect with the machine. Lightburn does recognize the machine and COM port. I am able to use the “move” function on lightburn and the laser head does move and even get correct “home” with the exception of 0.03 on each axis.
The main issue I am having my machine will not move at the command of lightburn from the “home” position.

ALARM:3
Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.

When I try to run a gcode it gives me an error saying the cut may be out of bounds. All the settings were pulled from the machine into lightburn.
Look for drawing remnants outside the laser workspace.
Use Crtl-A to see if there is something out there.
If you are using Image or Fill modes, you might be going out of bounds with the overscan setting.
Controllers vary on how they report the position after a Home cycle. This is not necessarily a problem. Use Absolute Coords for reliable positioning accuracy and repeatability.
Yeah, Alarm 3 is funny that way. If you can, upload your Lightburn project file (.LBRN2) so we can take a look at it. It will also help if you enter $$ in the Console window and tell us what you see for $130 and $131.
