Tumblers with 2 watt ir

Trying to do some tumblers with the Ir laser. Does anyone have any suggestions on what settings to use?

Also what do people do for tapered cups?

What sort of tumblers? What’s their coating?

For Tapered cups/tumblers we tilt the rotary.

Here is a picture of the tumblers Im using for test.


See how its tapered at the bottom tilting I don’t think would work.

Start by using the default setting for painted metal, then adjust your speed or power as necessary.

I would use a slight tilt on the top part to maintain focal distance to the material as that part does have a tapper still. You will not be able to “step down” to maintain focus for the lower part, in one burn. You may try and use the top and bottom part for one burn but the bottom may go out of focus and lose clarity if it burns at all.
