Engraved a Zippo lighter today, my 5th item on the GF.
Measured depth/height from inside floor to topside of crumb tray honeycomb.
Removed the crumb tray, then zero’d out my calipers, and measured the thickness of my standoff including the Zippo (0.204" in my case).
Taped the Zippo in place, then taped a template cut from regular old manila folders (0.040" thick).
Imported my artwork, and set the engrave to:
750 speed / 8 power 225 LPI 1 pass - For Manila Template Focus (You won’t use this, but 0.244")
Then after nudging around the artwork to get it centered on the Zippo, I removed the template and bit the bullet.
First pass was:
750 speed / 8 power 225 LPI 1 pass - Test Engrave (still no going back though) Focus (0.204")
Looked good, though the soot/smoke from burning off the matte coating had me worried that it was going to be messy
Did a repeat of the first pass, looked better.
750 speed / 15 power 225 LPI 1 pass Focus (0.204")
Reset params to the following:
750 speed / 15 power 340 LPI 3 Pass Focus (0.204") Engrave Params
Took about 14 minutes for the final high grade engrave.
