Not burning bottom edge of file

I just purchased a Yora 6550 15w laser. Works great doing ceramic tiles with one issue, the bottom edge doesn’t burn. It shows up in the preview, but doesn’t burn. Any guesses? Here are some pics of the preview and finished product.


It is burning it, it’s just burning it all in the same place, which is why you have that long dark line on the bottom of the name.

Most likely your Y axis belts are loose, and when the motor reverses direction at the bottom when it starts engraving, it has to take up all that looseness before the laser head starts to move again.

Thanks! I will go give that a try!
