If you do not program I or J the controller will assume that the value for them will be 0 (zero), i.e. no need to program I0.500 J0 as J0 is assumed.
I would suggest that your problem is that you may not have the helical move option on your control, thus explaining the reason for the Plane error.
Even if you do not have the helical move option, you should still be able to program arc moves on the XZ or YZ planes using the G17 G18 G19 plane selection commands. |
