I have a generic, knock-off laser that came as a bonus to a 3D printer. 1w, 445nm, uses g-code/nc through an SD card and the 3D printer’s interface (not sure if it’s Marlin). What would be the procedure to control this with LB?
Hook it up.
Open Lightburn.
Power up laser.
Select com port in Lightburn.
Create a manual Device type as GRBL (NO SUFFIXES).
Confirm an active connection has been made in the Console window.
This should get you started.
Thank you Mike. This laser connects only to the 3D printer via a tiny 2 or 3 pin control-board connector (and therefore not to a laptop), and the 3D printer also does not connect to a laptop. Files go through an SD card inserted directly into the 3D printer. So no obvious way of connecting the laser directly to LB.
Once you get your design, Click the Save Gcode button and save as an .nc file and write it to the sd card…
Make sense?
Yes, makes sense. But in order to have the “Save GCode” option, LB forces you to either physically connect a device that it recognizes, or manually input your own device. If you input your own device, it still makes you choose a type of device. I assume that that choice matters as far as whether or not your files will render correctly when lasering.
My co2 doesn’t run on gcode, so it has to know the controller and the flavor of code you are using. You will have to give it something to go on. It uses lots of information related to the machines configuration…
You will have to figure that information out to be successful. I don’t know the controller on that or anything else, so I can’t really help you there…
How do you create the code for the 3D printer now? Upload (drag & Drop to the reply box) about the first 20 lines of the file you send to the printer, using .TXT as the file extension. Like @jkwilborn might be thinking, your 3D printer may be using a proprietary program format.
You can create GCode files with Lightburn, but we need to confirm that is what your printer uses. If we get past this, then we can tackle getting your system operational with Lightburn.
