Using a Masuter Pro CNC w/ the 40w laser, and have purchased Lightburn for running the Laser. Very new to using lightburn, as in got it today for the machine I got last week. XY home on the machine is front left, and that is the machine origin as well. Have set up Lightburn with those settings. problem I’m having is that when I have tried to do a test, it keeps trying to go to the back right to start, as if that is the origin. It does this no matter where I’ve set the origin in the device setup. Any thoughts? thanks in advance.
EDIT - when i have the machine at its home position, and I tell it to “get position” it returns a value of X -377/Y -377. Is there a way to set that to zero to make that home? I have tried setting the start from absolute coordinates, and it doesn’t help.
Please post a screenshot of your entire Lightburn screen with your project loaded and the Cuts/Layers Panel and Laser Panel visible. Also post a screenshot of the Device Settings Window (Wrench and Screwdriver icon).
Adding to what @thelmuth said, enter $# in the console window and report back what it says next to the G54.
here’s another shot of the move screen, with the machine homed showing what it thinks the position is.
I have very limited knowledge with CNC machines but I see 2 things in device settings. First, disable pointer offset. Even though it has a zero value don’t need to confuse things. Second, and I’m only guessing here, what happens when you enable CNC Machine in top left under working size?
Enabling CNC setting changed the XY values to positive x377/y377. Had it frame the test, and it did it in the top right corner of the machine. Sending it to origin sent it to the top right corner.
You need to get your machine reporting 0 ,0 when it’s homed. Have you homed the machine since enabling the cnc machine toggle in your device settings? Maybe this will help:
If you test out all the arrows in your move window, does your machine move in the correct direction? If not, you may need to change your $3 value, axis direction:
Forget the origin button for now. Where does it go when you click home?
IF it Homes in the front-left corner, enter
G10 L2 P1 X-377 Y-377
You only need to enter this one time. The controller will remember it. It will put Origin in the same location as Home (ignore any small non-0 values)
Mike, Tim -
thanks for your help. it’s homing properly now, origin is where its supposed to be, and controls are working properly.
thanks again.
