Láser module course marks

Hello, I introduce myself! my name is Álvaro and I am from the Basque country
I have a problem with the laser, when I am going to engrave painted aluminum bottles, the path that the laser takes from the point of origin to when it starts to engrave marks the piece. Is it a configuration error? thank you!

Hi and Welcome,
Update the Firmware and luban to current version. This behaviour is known when using old firmware with new luban.
