I take it that turbocad cam will only code incremental on an arc

for me absolute is easier to read

same arc, one is incremental and the other is absolute. If it is possable to to absolute let me know. It's not stopping me from doing any projects I just would like it the other way. It's like, the the grass is always greener on the other side of the road.

I guess I dont really have a response. My experience with CNC has been limited to TCC.  For me it works, so I dont question it. In other words, I cant read it, yet. But I am doing some studying.
