I have been laser etching wine glasses and currently do not have a z-axis. Limited to a relatively flat (vertical) region of the glass. Ready to add the z. Have stated on a software solution where I store various glass profiles and select at etch time. Would prefer a non-contact distance sensor and let the application do the figuring.
BTW - I suspect the laser is much more forgiving than a cutting tool. Do you do multiple passes?
HI
Yes I do multiply passing , setting it to about 8 passes 3mm just to divide up, then when I think it looks okay I stop the cutting.
For this example it only had 3 passes.
I would all so like to make my ovn distance sensor so I can level out the curves there are in the bottle.
It could be nice if T2Laser could read a surface profile in x,y,z and do the math in that case we would be able to drill on every surfaces

A surface profile scan would only require that it reads the z- distance censor in a x,y resolution by 1x1cm grid (maybe less 0,5x0,5cm grid)
