I just added a 4th Axis to my Shop Sabre CNC machine. I need some help getting MadCAM/post processor setup up correctly. I was able to get MadCam set up so that it would generate what looks like a good toolpath as well as the simulator looks like it's doing what it should. The problem is that when I generate the G-Code it is not rotating the 4th axis. It puts a value of "W0.0000" on every line. The value should be somewhere between 0 and 360. Here's a sample of the first few lines of output:
G80 G90
M3
G0 X0.0000 Y7.7832 W0.0000
G0Z3.0825
G0Z3.0625
G1 Z3.0000 F" "a" feed"
Y7.7883 Z2.9954 F W0.0000 200
Y7.7936 Z2.9899 W0.0000
Y7.7981 Z2.9844 W0.0000
Y7.8018 Z2.9789 W0.0000
Y7.8046 Z2.9735 W0.0000
Y7.8067 Z2.9681 W0.0000
Y7.8078 Z2.9627 W0.0000
I have it set up for simultaneous 4-axis output, I have not tried indexed output to see if that works instead. Any ideas?
