3D preview

Post by gpeck »

I am useing a 3D gorilla clipart from vectric for a 6x7 box top. After previewing cutting the rough cut with a .25 end mill. I set my finish cut at .04 below the survace for the finish cut. When I preview the finish toolpath it is not smoth like the model. Will it cut like the preview or will it carve smooth like the model. I am useing a .125 ballnose bit with a 7% stepover. I really do not want to start cutting, it is over a 2hour carve time. Thanks for any info... Gene

It will turn out like your preview shows. Aside from 0.04" lower, what settings are you using? What type/size of bit for finishing?

That is what I thought . I used a .25 end mill with a 40& stepover and a ballnose .125 with a 7% stepover, raster 0.0

Try a preview with a smaller finishing pass stepover. Maybe 4%? See if that looks better.

In V-Carve 8.5 with the same bits and settings except on the Finish pass I am using a .25 diameter (.125" radius) ballnose. I am getting total time of under 49 minutes (3 passes - 3D Roughing pass, 3D Finish pass, and a pocket pass around outside of model).

I did the same toolpaths on two other computers one is running win 7 and is 10 years old. The other one is running win 10 and is three years old, the preview came out great on both computers. The computer that has a bad preview is running win 10 and is only two years old. What is going on??? Thanks Gene

Are you using the same file on all computers? Is the preview quality setting identical?
