A long overdue post probably because I wanted to write something a bit more in depth for it. In the last batch of LRP items I cut for Eldritch I also cut this cupboard door blank. It's a simple square with low power lines running out to the corners, the problem was the engraved squares indicating the inner panel. If I were to engrave these normally the whole thing would take 2 hours to do. This is because the laser would move from left to right across the whole panel, spending most of it's time doing nothing in the big blank expanse. Vertical engraving is time consuming.
It made me think about what the laser actually does during the horizontal engraving. It cuts a line, moves down by the scan gap amount and then cuts another line. It would be possible to draw this pattern and get the laser to behave the same while it was cutting rather than engraving. To speed up the panel the vertical engraving was drawn in exactly the same way, so instead of engraving the whole height it would draw a series of lines from top to bottom. The final pattern took just 20 minutes to 'engrave' instead of the 2 hours a normal engrave was going to take. The other significant advantage is that it allowed me to 'engrave' the inner ring with more power than the other 2 rings.
Eldritch got these things a long time ago so I was able to find pictures of all the fancy foams now they've been latexed
