Laser just keep going to the right

LightBurn Software Questions
1

Hello everyone,

I am trying my best to learn these codes, but I am having an issue I just can’t seem to find an answer to. When I try to use the laser, not matter if it is a simple square or something complex, the laser just keeps moving to the right and will run into the sides of the CNC and continue to try to move. It won’t laser or anything. I feel like it is trying to home the device, but I think I have that turned off. Below is what I have for codes. Any ideas?

$0=10
$1=25
$2=0
$3=3
$4=0
$5=0
$6=0
$10=1
$11=0.010
$12=0.002
$13=0
$20=0
$21=0
$22=0
$23=0
$24=25.000
$25=500.000
$26=250
$27=1.000
$30=1000
$31=0
$32=1
$100=250.000
$101=250.000
$102=250.000
$110=500.000
$111=500.000
$112=500.000
$120=10.000
$121=10.000
$122=10.000
$130=200.000

What kind of “the laser” do you have?

If it’s a machine intended for CNC use, chances are it is set for negative workspace, with the origin in the rear-right. LightBurn wants positive work coordinates, with the origin in the front-left.

All your GRBL settings look like they’re defaults - the acceleration values are very low ($120 & $121), the maximum speed is 500 mm/minute ($110 and $111), and the size is 200 x 200 mm ($130 & $131). If this is a new controller in an existing machine, you’ll likely have some things to change here. Read up on GRBL configuring here: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration

And the most common GRBL setup things in LightBurn are here: https://github.com/LightBurnSoftware/Documentation/blob/master/CommonGrblSetups.md#common-grbl-setups

Answer back with what kind of machine you have and there might be more specific things I can point you at.

I have a J tech 4.2W on an X-Carve platform

Ah, then you’ll need a workspace offset, described in the 2nd link above, but you’ll also need to set up the controller. As I said, those all look like default GRBL values, not specific to the XCarve. You should find someone who has one already who can give you their settings, as that will go a long way to getting you running.

I don’t know if this helps you with what is going on,but I just switched to the Easel software for the CNC, and attempted a 2.5" circle and it made it 25"

That’s one of the things I meant when I said:

This time I have the codes I got directly from X-Carve.

$0=10
$1=255
$2=0
$3=3
$4=0
$5=0
$6=0
$10=1
$11=0.020
$12=0.002
$13=0
$20=0
$21=0
$22=0
$23=3
$24=25.000
$25=750.000
$26=250
$27=1.000
$30=1000
$31=0
$32=1
$100=40.000
$101=40.000
$102=188.947
$110=8000.000
$111=8000.000
$112=500.000
$120=5000.000
$121=5000.000
$122=50.000
$130=740.000
$131=790.000
$132=100.000

Everything seems to be moving correctly now. However I have no laser that is coming out during cut. I checked and I have the fire button enabled. Any ideas?

In the device settings, check to make sure that your S-Value Max is set to 1000, to match the $30 setting in the controller. Assuming that’s correct, the laser should be working. If it’s not, it isn’t the fire button - that’s only for focus / framing. During a job, it’s the Max Power setting for the color layer you’re using for the shapes. If that’s not zero, you should see a beam.
