8. Highest speed for X and Y axis 60 IPM.
9. Highest Speed for Z axis is 40 IPM.
IPM - inches per minute...............feedrate
Actualy it's a vague statement. You could have your machine setup for a higher velocity and the gcode will limit the feedrate when machining.
Not seeing the gcode it is not clear what the heck is being said.
But then you also have ....
Mach 3 needs to be set to arcs.
Only you would know as we don't have the "photo"
Suggest you do some reading on CNC before running programs made by others that you can't relate to.
