Pretty new to all the detailed jargon about diode lasers and LB. ???
Q: if ONLY the laser is powered on, through the basic 3-axis, GRBL 1.1f controller, …and the drive motors are NOT connected, (wired up) should LB be able to find the laser ?
At this time it doesn’t connect. I haven’t tried the “Marlin” (?) type as yet.
I’ve probably missed something in filling in the blanks during set-up.
Thanx for any posting.
LightBurn only directly communicates to the controller. So as long as the controller is connected and powered then LightBurn should be able to communicate with it, assuming that your computer has the necessary drivers.
What controller are you using? I assume this is something different than the Sculpfun S9 that’s in your profile. If this is Sculpfun S9 then the device type should be GRBL.
LightBurn doesn’t always successfully detect laser but should assuming the controller is powered, connected, and has the right driver. If you’re on Win7 as per your profile then you’ll almost certainly need to install a driver for this to work. Windows 10 and up usually do not require explicit driver installation.
Many Thanks for the reply. Previous setup used Mach3 and separate breakout board and controllers.
So adapting it to suit LB is a new thing for me. The controller is a no-name 3-axis unit with laser and router port… indicates that it is compatible with grbl 1.1f. (also new to me)… but I am still re-pinning the motor wires to fit, and will have to test them for correct motor direction.
I will see about an appropriate driver per your suggestion,… as I haven’t tried that yet.
Again thank you, and I will post progress as it happens.
Cheers

Do you have a link to a description of the controller? Most of these will generally use a handful of different drivers, typically CH340.
So Sorry… the best description was off of the Amazon ad.
Couldn’t find any tech details, or even the manufacturer.
Came packaged with no additional info…
I have read about the CH340… and will see if that helps.
- Name:Updated USB Port 3Axis GRBL 1.1f Control Board V3.4
- Input voltage: 12-24VDC (recommend 24VDC)
- Support software: GRBL Contol/Candle(3 axis)/Universal Gcode Sender;Support System:Windows XP/7/8/10
- Support XYZ three-axis control, spindle.Support stepper motor: 12V, maximum current of 2A or less is recommended within 1.5A and additional heat. (Any stepper motor 42, 57);Support spindle:24V 2A Support Spindle PWM speed (0%-100%)
- Master chip: atmel 328P (arduino nano)；
If this is Arduino Nano based then for sure it’ll be the CH340. If you’re having any trouble with it LaserGRBL is bunded with the driver and you can install from the menu.
Just to let you know… your advice was rock solid.
After a bit of fiddling, was able to download and install the ch340… and LB came up with the “ready” note when I opened it up.
Just have to wire up the nema 17s, and limit switches, and should be able to make some smoke.
Can’t thank you enough for your advice and help. Looking forward to the first (of many) projects
Best Regards
Ray
