I'm not sure of what you mean by the CAM system or if it is relevant to what I do. Possibly someone can explain. I write Java code that exports g-code files to run a small CNC router or CNC desktop mill. I am considering adding a lathe like attachment bolted to the table (essentially a small

On a machine with a rotary A axis, if I run G91 A360 X10 F100 the machine moves 100IPM on the X and the A axis completes a 360 degree rotation at the same time. If I then run G91 A360 F100 the machines takes almost 2.5 minutes to complete the rotation, because it is only running 100

Its definitely set to angular. Len For your check, make sure the 4th axis is set to angular as the first thing to check in the .ini file. -- Monitor 25 network devices or servers for free with OpManager!
