Picture engraving help
@judy2478 Just remember the "centers" will match.
Where you set 0,0 is the center on the laser and aligns to the center of the image (total pixels, so your design must be centered in the image). If it's off then perhaps your image has more white space on one side or you aren't finding center of the item (if it's rectangular you can draw lines from corner to corner and the intersection will be the center).
@judy2478 Let me explain the basics.
Set resolution to match the laser spot size, typically 0.15 to 0.20 (it depends on the laser power and focus).
Set laser min to 0 and laser max to 255 (using my firmware and default parameters).
Use feed rate to adjust the burn, increase to lighten and decrease to darken (start at 1000).
How do you know what the lazer spot size is?
@thomas75 If you set resolution to 0.2 and see white lines in the engraving then you can either de-focus the beam slightly to make it larger or reduce the resolution a little, like 0.18 or 0.16 etc.
The higher the value the faster the engraving, and on larger engravings you really don't want to use less than 0.2 but on small detail maybe 0.16 or even 0.14 would be perfect.
@Zax Ok thanks,Its really hard to do a photo burn and get it to come out right.
Forgot to ask,when you are doing a photo do ya use photo mode?
@thomas75 No, in fact it should tell you not to manually enable it. Photo mode is a "work around" that is rarely needed but will enable automatically if T2Laser determines it would help.
