You need to adjust your limits in the program as the defaults are blank. I'm not sure what the chip load is suppose to be on a 4 flute but assuming .002 you'd want to run 2nd pulley and 13IPM. There's no way you're going to get a decent chip load running at 10k rpm.
You could try 3rd pulley 22IPM but you're getting pretty close to .05HP according to Gwizard. So far I've found that right around .05HP seems to be the limit on my machine in terms of rigidity.
