I have been doing a lot of 2-3 inch diameter variable engrave “Tests” at 2500 speed full power and 1355 LPI and a customer wants one 10 inches in diameter. After several tries spending a long time thinking about it, the GFUI kept coming back with “you’re kidding! right?”.
So first I dropped off everything but the engrave trying to ease the job, and it still laughed at me, so I dropped the LPI in half and it still refused but I refused to take no for an answer and just tried over and over.
Eventually, it decided to submit and gave a time of 51/2 hours.
Now looking at it I see it will need two passes
What is everyone else’s longest single-pass time?
Ended up about 10 hours of Glowforge time, was two passes.
