I’ve been using my laser setup for a couple years now successfully (Shapeoko 3 XL with Endurance 10w laser attached) . Just today when I tried to start a job, things acted normal until about 1 second into the job when the laser shut off all the motors stopped. Lightburn showed the job continuing, but there were no lines of Gcode showing in the console. One thing I did notice is that all the GCode console text is now red, when before it has been black.
I am planning on replacing the current laser with another newer module and in doing so was looking at the parts that I need. I was checking to see if the JST plug on one of my radio control airplane LiPo batteries is the same as the PWM output plug on the Carbide 3d controller board. Not thinking about the voltage, I stupidly plugged the battery into that port for a couple seconds to check that it fit (the laser and the CNC were turned off). This is not the battery output wire, but the control plug for balance charging it, but there are still 8V measured on the wire. I’m wondering if I might have messed something up on the board when plugging that in for a moment. Things have been working fine until that point. I think I might have inadvertently done somethings pretty stupid.
Most led laser modules will handle the full 12V on both the input power and the pwm. If that’s where you plugged it, probably not. Some of the modules specify ttl for the input of the pwm and that is limited to 5V…
Assuming a failed led module, how could your controller know that and stop the machine? If it did stop the machine, why would it not report that error to Lightburn?
If you plugged 8V into a 5V board (controller) that could be an issue.
It probably isn’t lightburn stopping your machine if it’s still streaming data to the device.
If there is red text, it usually indicates Lightburn got some kind of error. Can you ‘scroll’ back and look for a reported error. When this happens, lightburn quits sending data to the device.
This isn’t making sense to me… can you add some more information? Like does it otherwise operate, homing, frame. Can you do just a box?
The laser works fine. Every time, the job starts and the laser and motors run for 1-3 seconds and stop. Lightburn shows no new code in the console, but acts like the job is still running. When I stop the job, then it automatically homes the machine. I’ve tried just doing a box and it changes nothing.
I tried it with a different computer running Lightburn and it does the same thing, except that the text in the console is still black, not red.
I’ve got a 3d printer that can run the laser, too, so I’m going to try and see if it works on that. That will narrow down whether it’s a Lightburn or CNC problem.
This is the code that I see when I try to laser a test file
