This is kicking my butt, my otherwise awesome settings for cutting 1/8" acrylic (for a near flame polish ready edge) are destroying my 1". I'm getting chatter and melting (air bubbles) on the edges.
Having trouble figuring out what direction is warm and cold to move in, right now I'm doing 4 passes 18k / 140 with ramps and a .3 offset and another, final single pass without offset. I broke it up to get some extra retraction, I am having pretty gnarly chip buildup though none of it seems solid.
For shits and giggles I threw on my micro drop mister and I'm not seeing much of an improvement.
This is the bit I'm using, new as of a few hours ago.

Any pointers?
