I recently purchased a desktop CNC mill. I am using bobcad v17 to write my programs. I am using Mach 3 to run my mill. I'm farely new to CNC and working to better my skills with programing. My issue is with G41 and G42. I can not get my mill to compensate for the cutter(which is a 0.25 endmil). Here is a partial of my program I wrote. Can someone tell me what I'm doing wrong.
