4rth axis help

[duckdogers]

hi guys I keep on getting error on op4 while the other 3 post ok.not much experience with  rotary so any help will be appreciated.Running this on a hass machine

Mastercam's Default "Back" view has the X and Y rotated from "TOP".  By using "BACK" you are telling the machine to rotate the part in two axis which your machine is not capable of doing.  Instead, create a new View that is rotated about X with the Z point towards the face that you want to cut.  See the attached program.

PART.MCX-7

thanks john.Question-after the part gets rotated what happens to other planes,does the top not become the front

[JayM]

No, for 4/5 axis work your WCS should be fixed for all operations, think of it as your G54 work offset on your machine.  The Toolplanes are what create rotations in Mastercam, you will have one toolplane for each position that you want to rotate to.  Those toolplanes should have the same origin as the WCS just point Z at a different position from the WCS.
