The C axis (for cutter angle) will just be another axis on the machine, so EMC, itself, needs no change. What does need to be done is create a filter program that takes in G-code with XY commands, figures out the cutter angle and adds in a C command word. For any G01 moves, the calculation is trivial. For instance :
Input file, currently at X0 Y0 : G01 X1 Y1 Output file: G01 C45 X1 Y1 So, it sets the cutter angle first, then performs the linear move. For arc moves (G02, G03) it has to preset the cutter angle for the start of the move, then program the cutter angle to follow the changing angle of the cut move. Input file, currently X0 Y0 : G03 Y1 R0.5 Output file : G01 C0 G03 Y1 R0.5 C180 This is assuming C=0 is with the knife pointing toward +X, Positive C is counterclockwise, and that I got the arc direction right.
