Darkened edges on mugs

[niftythings]

Has anyone else had the issue where the edge of the engraving on a mug/H2O bottle or the like, is darkened, almost looking burned, or the laser didn't go deep enough? We have tried to adjust by moving the image/text over to the left but if you go too far it does it on the left hand side. Just curious if anyone has figured out a solution.

Anyone? Anything? Have also sent a question into customer service with no reply yet.

Does this problem appear only on some specific mugs or water bottles, or is it all ZHZO items? One thing to try is re-calibrating the Z-axis; instructions can be found in this document, #4 (pages 8 & 9). http://www.laserengravings.info/Lase...er_Support.pdf

Hey Tim,
We have tried that, and it doesn't seem to be product specific. It tends to be hit and miss with the image and wording. I just did a ZHZO39 and it was a butterfly with a name below it and it did it right on the edge, leaving it black, like it isn't engraving all the way through. If you'd like I can send you photos of what is going on.

Thanks, Jessica
