Hello, I recently began to use Lightburn (its great)with my ortur laser master. Although I have gotten it to work, for a bit, I have never been able to set a Origin point (when I click the button nothing registers), or click “Return to Origin” because everytime i do, I get a busy message (next to the green progress bar). The only way I can reconnect it is turning the laser off, and on.
Now, if I click on “return to home”, or after a print, I run into the same problem. And get a “the laser is busy” message that pops up (i closed the program, and opened lasergrbl, to do an engraving, and tried to connect the laser to my computer and got a prompt “Access to ‘COMP3’ is denied”)
Does this sound like the controller is defective? Or do I have to change a setting somewhere?
Well, now I can’t do anything, I accidently clicked “use Laser” in the consol window, and now its completely locked out, can’t do a single print with any program. Is LightBurn locking my machine out?
Did you try restarting Ortur, and Lightburn
When you do and connect, can you click “Show alL” in the console window then type in $# and post the output?
How did you configure your machine? Homing front left? GRBL 1st option?
Regards
Thank you for your reply,
Here is what comes up after typing “$#” (also, if you notice the green progress bar, that won’t go away)
Yes I did set the machine up as you said, front left is my home position.
I just tried lasergrbl and the consol is now saying the same thing “reset to continue” like lightburn, and hangs up the laser.
That seems to be the problem.
Not exactly sure how, asking @LightBurn for help but you have a offset on your EEPROM
The G54 values are a offset . which means the machine thinks is at 400x430 when in fact its at 0x0
This causes any job to go right into the rails, triggering soft limit or even hard limits issues. (aka head into rails)
Can you type in console the following
G10 L2 P1 X0 Y0
Press enter
Type $# again
At G54 line it should be empty
Then try to see if troubles persist?
Regards
Woohoo!! Thanks a lot! Took care of the problem. I got all this written down, just in case.
Thanks again!
With the Ortur laser you shouldn’t have gotten a “Use Laser” macro. I suspect that when setting up the device, LightBurn asked if you had an XCarve, a Shapeoko, or “something else”, and you picked one of the first two, but the Ortur laser is not an XCarve or Shapeoko, it’s “something else”.
I’m not sure how to make this so people don’t choose these options in error. GRBL devices are a pain in the butt, because CNC-style machines use negative coordinates, and lasers use positive coordinates, but there’s no way I can find in the firmware to determine which is which, so I have to ask the user, but most users don’t actually know. Asking if you have an XCarve or Shapeoko seemed pretty straightforward, yet people keep getting it wrong. Not sure how to address this.
Thanks for your reply,
Yeah, I tried all the options lastnight, and this morning, and Xcarve was the only one that allowed me to make multiple prints without hanging up the laser (not just the first option I picked). I love the software, though it seems it has a mind of its own at times. However, the gcode that ortur gave me to plug into the consol worked perfectly.
The problme seems to be that using xcarve or shapeoko then sets a permanent offset to the eeprom
shouldnt this be a Prompt, or a warning? or would this add even more sand in the cogs?
I dont mind it, as long as i understand HOW and When, that way we can advdise costumers not to do so.
I will try to replicate my end.
When you go through the ‘Find my Laser’ setup process, it finds a GRBL device, and pulls some information from it. None of these devices have any uniquely identifying markers that I’m aware of. If there was a flag I could check for negative workspace that would help, but I don’t believe that there is.
I could check the workspace size, and if it doesn’t match the known sizes for XCarve / Shapeoko, I could skip that question. What I really need is a way to identify that a machine uses negative workspace, and go from there. I have some ideas to try.
You think theres a flag firmware Engeneers can code in to help?
Not sure how expansive GRBL is in terms of flags
I could inquire internally if you think is doable.
In order for it to work for everything it would have to be in GRBL itself, not just your specific version. I should be able to determine the workspace sizes for the XCarve and Shapeoko machines, and not ask the user at all if it’s not one of those preset sizes.
I can also clear any workspace offsets, home the machine, then do a G0 X0 Y0 and ask the user which corner it went to. If it’s front-left, they don’t need the macro. If it’s rear-right, they would. I would need to add a bunch of code to the auto-config tool to manage that though.
I understand. Also after some thought a Tag would only adress Future machines and firmeware updates not past ones.
I am getting faster at identifying the problem but if it could be avoided somehow would help
Probably it affects not only Orturs but other GRBL machines if on wizard user checks Xcarve/Shapeoko
Even if then in future they reconfigure Lightburn right, the G10 is persistant so needs to be manualy cleared.
Funny enough that could cause some issues. Customers with the Little ortur at times miss judge which is the front and the back of the machine.
Ortur logo = Front left
Where at times they use the motherboard as Front left
So i guess that could cause issues too.
Just thinking out loud and adding some thoughts on the input i been collecting
I have seen that one too. 
Silly question but, is there a way to “import” a machine configuration as well as settings into Lightburn.
A method that would be GUI based rather than drill into the folders structure
We could attach config presets maybe?
This way we would bypass that mm/min mm/sec issue as well we discussed earlier and mostly have a default for Ortur machine preset
EDIT: Maybe in the start wizard, add a Import button that would allow it?
You can Import / Export from here.
Will it also import Lightburn settings?
Thing is at that stage user already went past the wizard, at first use.
This imports only the settings for the device itself, and the latest versions of LightBurn start the user on this screen, not the automatic finder.
Any advice on creating this import files. Some pitfals to be aware regarding for example PC/MAC
Windows versioning etc?
