Hello,
I am having trouble connecting my Ortur master 2 laser with lightburn. I am currently using the latest trial version of lightburn.
It was working fine for days until I woke up one morning to use it.
Under “console” I am getting the message “waiting for connection”.
Under “laser”, I am getting the message “ready”.
I am using a windows 10 laptop.
To troubleshoot so far, I’ve tried to make sure that all the plugs are connected. I unplugged and reconnected a few times. I uninstalled and reinstalled grbl… I turned off computer and back on.
Any suggestions would be helpful at this point because I can’t get it to start up again.
I assume you tried to find the laser, by clicking “devices”, under the LASER tab? The tried to discover your laser? Also, swap out your USB cable. Let us know.
I just set up a Mega2560/RAMPS combo with Marlin and ran into issues that I did not recognize at the time may be the same as what you are having… I spent 3 days debugging…
DTR
I found that if I issue an old school DOS MODE command for the port your engraver is on and enable DTR all works.
Further testing indicates that in order for my workaround using MODE COMx DTR=on you must set the DTR switch in Device Settings to OFF (thats the default but if you have been struggling like I was all bets are off as to what you might have tried!!)
Also GRBL seems to use 115200 baud and marlin seems to default to 250000 baud and I have shot myself in the foot multiple times when switching between them…
Hi guys, I had the same problem with connections Arduino Due CNC Protoneer v3. The new versions after 1.0.0.0 have a problem with stable connect, maybe some from @LightBurn may check logs. The old version of LightBurn working right, more description is here:
