I’m trying to get colors on a stainless steel tumbler. The only way I can get colors to show up is when I have the rotary disabled. What do I need to change in the rotary settings ?
my guess is its tryint to turn the tumbler with the rotary instead of moving the galvo in that direction and the rotary does not have the required resolution to get enough lines per inch in there to actually make it look like the colors you want.
Disabling the rotary makes it use the galvo system to precisely move the laser to where it needs to be for the color effect.
But i couldnt tell you if theres a setting for that which somehow moves the rotary only a little and then lasers entirely with the galvo head before doing another larger rotation and repeating that till its done.
I haven’t tried, but can you “Run Whole Shapes” on the test grid?
Galvo/ rotary doesn’t work that way. It turns the tumbler one “Split” increment, then fills that split with the line interval. Splits can be equal to or greater then line interval. (Maybe even less, haven’t tried)
I think the issue is the nature of the test grid itself, on the flat it fills each square individually, with rotary it fills each slice (depending on optimization settings) so heat profile and power density (Maybe same thing) are different, and precise control of heat is what gives the stainless the colors.
Have to experiment a little bit more, and then when you go to the actual artwork probably find you have to change up the parameters again.
