I'm having some problems cutting G2/G3 arcs on my rotary axis. Basically I am using Sheetcam to generate standard X,Y plane G-code, then using a text editor to replace all the Ys with As to use my A axis. Works fine until I,J arc centre words come up, then the REAL Y axis starts to move and not my A. I figured if I used the "G2 R..." notation this problem would go away - is there a setting that I can change to effect this, or does it require a different post? Currently I use the standard Mach2 post with no other problems.
Thanks
