Scale issue (y difference)

Good morning,
I draw a 5cm x 5cm square on ligthburn and my laser (Atomstcak x24) engraves a 5cm x 4cm rectangle. The rotary is inactive. Can you help me ?

Check the machine (firmware) settings, which values are set for the steps/mm for each axis.

Thanks, but there is no firmware for this device, all settings are on lightburn

That’s impossible :slight_smile: Every machine needs to have a controller running and that uses a firmware for its function. You can access the firmware settings by choosing Edit->Machine Settings in LightBurn. Open the outputs section and search for x and y steps/mm values.


Yes that’s right. Thanks for your help.
