Thanks for your input. I did realize today that I am doing this a little backward. These letters were supposed to go to waterjet but my manager gave them to me at the last minute. I had to program and cut immediately and, since I'm new to this kind of depth, I wasn't able to come up with the...

So, I tried the 400 ipm at 18000. It seems to be cutting nicely... still a lot of heat on the bit though. The spindle is getting pretty warm as well and that's the part that concerns me. I guess I just don't know how much heat is too much for the tool or the spindle. It's hard to say what is...

Sweet! Didn't see the video link the first time around. I'll try it out! How did you find this video. Looks like it was made by Onsrud? Thanks again!

Yes, that's inches per minute. I used a speed/feed calculator that got me to 432 ipm at 16000 rpm. I kept adjusting from there because I was still getting a lot of heat built up and not very large chips.

Does anyone have any tips on cutting 1" acrylic letters with a 1/2" bit. I have been adjusting my feeds and speeds to try and eliminate all the heat on the bit. Right now I'm at 475 ipm with 14000 rpm. I've been adjusting to get a larger chip hoping that will cool the bit but the more I...

I think that the city we are dealing with requires that there be zero light transmission through the background and that is why my company is going with blockout. Do you ever run into issues with your plotter cutting two long runs differently? It's the same file ran on two different materials.

Sometimes it is necessary to put blockout behind vinyl graphics so that only the logo or copy is lit at night. In the past I have had trouble getting the cut vinyl to line up with the cut blockout. It seems like the plotter feeds the two materials differently because when I do long runs, the...
