Hi Newbie here, I have been looking in forums but can’t seem to find an answer. I have just recieved a Falcon2 and installed LaserGrBl as well as Lightburn. The laser engraver works fine with LaserGrBl, even with the limited softwares ability. I downloaded and entered the profile for the falcon2 into lightburn and put a simple design ( a small circle). The software recognises the falcon 2 and frames as expected, I have then sent it to the machine and started it. The head moves to the correct position and continues to move as if it as engraving or scoring, am I missing something really stupid?
Are you sure you’re not just framing? Can you make a screenshot and tell where you have clicked?
Hi, thank you for the reply. Yeah I have pressed start, not frame. The head follows the pattern of the project but just the diode doesn’t fire on. I’ve updated the firmware on the frame, as well as the laser head. I have now downloaded Falcon design space, to try that. It does the same as lightburn! I process the job, I frame it to make sure its in the correct position. I then press start (after checking power and speed settings) and the head follows the shape I’m trying to engrave but the Laser doesn’t come on.
As I said previously, it burns and cuts under LaserGRBL, so its seems the diode is ok, the hardware is definetly communicating with all three pieces of software, but 2 of the 3 softwares don’t fire the laser.
I have read somewhere about the S setting should be 1000, which it is. I also clicked on the layer to make sure the constant power mode is selected. When I first boot up lightburn with my machine (Creality falcon 2) here is the printout from the console:

Not sure if this helps? I’m not familiar with G-Code unfortunatly.
If it says GRBL there you probably have a standard device selected and not imported or selected the .lbdev file for the Falcon 2. Try to import the file with the laser profile again.
Hi Sebastion, thak you for the reply. I deleted the device and then re selected GRBL-M3. Lightburn is now firing the laser as I would expect. I’m not sure how to get around this in Falcon Design Space though. I would prefer to use FDS rather than Lightburn if I’m honest.
