Losing my mind - mirror acrylic flashback

[nickstock]

Have you tried using these?

Suspended ablation

@takitus, thank you for that link! It got me thinking of something similar - but rather than a hold-down, a rise-up: [IMG_1204] I used some scrap acrylic, but it could be any material less than 4 mm thick. The eensy risers elevate 3mm, which is plenty high enough to avoid flashback, low enough for my magnets to still work well, and be easy to pluck out afterwards. I’ve attached the .svg (or at least I think I did…) [riser]

I use them all the time now when cutting pretty much any acrylic to avoid potential flashback (tell tale jagged cuts at the bottom of the acrylic - especially noticeable on 1/4). With the autofocus feature on the GF elevating things with these little doodads has been a godsend. HTH.
