falcon 10w burning ovals that should be circles

hello,

I had a rotary chuck on my falcon, now that i want to go back to flat work, it is engraving the circles as ovals

Check the steps per mm. Probably the X and Y axis are not the same.
Enter $$ in the console to show the parameters.

thank you. I found it by dumb luck. the $101=80 was not right

I watched a good video on youtube from the LaserGuy. It showed how to calibrate your machine in Lightburn using a piece of basswood. You cut a 150mm by 150mm square, use digital calipers to measure the square then, input the measurements into the calibrate axis section of the machine settings.
The next 150 by 150 should be almost spot on…

Cheers,
