4th axis programming issues 840D

[markp]

Made a cylindrical part with 4 ports on my DMC103V 840D control. Ran into a few problems that I was able to sidestep and make the part but trying to figure out what the problems in the code were. Cylinder with 4 ports. Polar milling with 3 repeats.

Program runs fine until it hits N1546 A-24.1245 then stops with a 16905 (syntax) error. This is at the end of the port where the depth stops so no more Z moves. I removed the A moves that were on a line by themselves and the program would run.

Second problem is the repeats. After the first port, the program dances around, repeating the ports its already cut, after a few repeats, it eventually cuts all the ports but never stops, just keeps repeating, switching back and forth between various ports. Watched it for a while but I didn't see any real pattern to how it did this.

Seems weird that having A moves on a single line would error out.

Heres the code:
