I’ve been searching the threads for tips on 1/2" acrylic and most of the notes were from back in 2017.
- I’ve seen that @scott.wiederhold recommended cutting with the following settings:
.433 focus height
3 passes @ 100% power, 120 speed
I know that there have been changes to the GF, so I’m wondering if these setting still hold?
Also I’m planning to engrave some text, reversed into the back of the plastic (making a plaque), and I’m wondering if it makes sense to maintain the material height of .433 focus or a true .5 focus height. (Yes, I could do a bunch of test and waste expensive material, but figured I’d ask first!!)
I saw posts on defocusing to polish the engraves, but in those cases it wasn’t engraved text. Is that recommended for text or just patterns??
I’ve typically preferred SD engraves over HD engraves, any thoughts on this with 1/2" acrylic?
Lastly, I know folks have commented on removing the backing paper first in some cases. Does this apply to the acrylic? Will it be better to remove the paper before engraving and cutting?
