- Setting up the focus as normal. Set the Work origin
- Lowering the laser head until it touch the bed
The -Z (focus) value will then be the high required above the bottle to be in focus. (made a note of this value)
3.Move the head all up to clear the bottle and then place the bottle on the Y-Rotary bed.
4 Lower the laser head to just touch the bottle. Set the Work origin.
5 Move the Z up the by the Z(focus) value. Set the work origin again and you are good to go.
if you already know the distance for your focal point the start at 3.
I engraved a company logo by taking an image (jpg file) rotate it 90DEG clockwise and then convert it to a SVG file. Upload it as Vector drawing
Got good results with
Jog Speed of 300
Work Speed of 300
and
power between 70% - 100% (depending on the color of the bottle)
Hope this helps
