Hello, i am new here and have a Little Problem with my construction.
Sorry for my bad english.
first i have a simple Question, how is to use the Focus Z Bottom? it is the Right at the Laser Movement.
now to my Problem, i have a Tronxy X5S based 3D Printer with 5W Laser for engraving and cutting.
How can i say Lightburn, that he have first to move my Z Axis to a specific High that i have optimal Laser Focus. If i Move it Manualy and take off the Z Axis it works. But Some Times i have peaces that have different highs that i want engraving. So i Need an Offset of the High of the Object aditional to the Focus High. Now i tryed to work with the Z Offset in the Layer Setting.
If i choose only the Fill Option ti works good. But if i coose any Line Option at engraving the
sometimes the Z Positon driving to 0 and than back to the Offset High.
Why he do like this? How can i fix this Problem?
Thanks for help and i hope you understand this Problem
For better Understanding i put a sample of the gcode here.
And i marker the orders in blod. They dont be needed, why Lightburn make this?
Need only at start of the Gcode one G0 Z41.
The reason is that LightBurn is cautious. Since you appear to be using a Z offset, not a material height, I cannot assume that the offset is “safe” to leave on at all times. If you were engraving the bottom of a bowl, for example, I would move to the start, lower the Z, do the engraving, lift the Z, then move away. If I moved the Z down and then moved the controller, you would hit the side of the bowl.
There is an option coming for GCode devices to optimize z moves, but it’s not done just yet:
