Poor engraving quality

Machine: 6040 home built

Board: C3d Laserboard

Firmware: Stock Smoothie firmware

Problem/ Question: Hello I’ve recently had c3d laserboard, got it all installed and running
But the engraving quality is quite bad. I could do with a bit of help diagnosing the problem.

As you can see there’s all jaggys and lines on the image. Thanks

Forgot to say that I’m using the latest Lightburn

We’ll need a lot more information about your setup.

Please provide pictures of your board, machine, and wiring.

Did you change any settings in the board config? And so on. Please tell us what you’ve done.

Got it sorted now. Put Grbl - lpc on board and changed line interval. Thanks

The stray lines on that design look like you had Smoothie clustering enabled without having the firmware that supports it.
