Engraving larger image

[Pineguy (Ernie woodburn)]

GRBL Diode, 15W. Have this image to burn. Just playing with the settings but it keeps burning the wide border on either side. Must be a setting somewhere.The image stops right at the C and the N.

Here are my settings:

$32=0

To start, Common GRBL/GCode Setups - LightBurn Software Documentation

Have a review of that and let us know how you progress. We can go from there.

$32 was 1 but I made it 0 because my vectors were coming out oblong. That solved that issue. Could it have caused this issue?

I put it back to 1 and it’s moving super fast now. Cant get an image even when I go down to .150mm @ 100%

$32 is the Grbl setting for Laser Mode. Here is the complete list of each setting and what it does: Grbl v1.1 Configuration · gnea/grbl Wiki · GitHub

The link I provided explains the settings required to have LightBurn work as designed.

@Pineguy

…vectors were coming out oblong.

This sounds mechanical. Check everything is snug and nothing is binding. If you draw a 100mm x 100mm square, what size is produced when cut?

[Pineguy (Ernie woodburn)]

Problem solved…I updated my firmware.

Glad to hear you got this sorted.

You should properly configure your machine, or you will continue with problem.

Did you go through Lightburn Common Grbl Settings?
Also is one for a CNC3018 type, not sure what you have.
Might also check out the docs on Coordinate and Job Origin.

You have Lightburn set for ‘inches’ and grbl controller set for mm.

$13=1 for inch

$32=1 for laser mode

$110 through $112 are maximum rate or X, Y and Z axes.
$120 thought $122 also seem overly aggressive, these are max acceleration.

$130 through $132 is for the max travel in your X, Y and Z directions. Doubt these are the proper values. Most of us don’t have a z axis that can run 500mm, maybe yours can…

Here is a ‘old’ grbl register values and what they mean. These are from a pre 1.0 grbl release, so $32 is not present. Hope it helps.

Good luck

Sorry missed Ricks answer…
