my spindle is max 12,000 rpm I tried slowing it down spindle speed and feed rate to 30 but same result. I understand the acrylic melting and sticking to the bit. But I haven't seen this inconsistency of cut on the other sides.. which leads me to believe its not only the bit. I am using a bit that is 2 flutes i believe and is an upcut type (not entirely familiar with all the different types) So I've noticed this same defect on my other cuts so it leads me to believe that there is some kind of hardware/controller issue... I've reached out to the manufacturer... hopefully they can help. I've worked with this machine for 2 months so still working out the kinks, I've used the CARVEY machine before this with much better results. Thanks for all the thoughts+1 to the other comments. I cut quite a bit of acrylic, from 1/8" to 1/2" thick, using a 1/8" o-flute bit. I realize that you are using a 1/16" bit. I run my 1/8" with a 30" per min feed and the lowest speed on my makita router, which I believe is 10000rpm. I would not push a 1/16" as fast as you are. You may want to slow down your feed rate on that bit. Is it an o-flute or a standard 2-flute bit? If you are getting any heat, the acrylic will melt and pull the bit off the line.
Of course, if you have had good results with your process in the past and if this problem is recent, just disregard all of this.
