I am new to using a drag bit so here is the question. I did an image that was done using the fill option. In areas the was filled the drag bit almost looked like it "tore" material on some passes so it left a very ratty. uneven finish. I used a .001 step over rate with a .028 down pressure on the bit. Should I be using a larger step over? Should I be blowing compressed air on the tip of the bit to reduce any build up while the tool is dragging. I did an image that was outlined with a .03 down pressure and it looked fine.
I am open to suggestions and any tips you might offer.

This is a duplicate post of

(actually the wording does differ a little).
You don’t specify the material so perhaps “tearing” is to be expected?

Re: drag bit question
What type of acrylic are you using. Cast is the preferred acrylic material. Gives good clean lines as opposed to some of the other “Softer” grades
