Hi All,

I've recently acquired a Robodrill with a Fanuc 16i-MB controller and have already hit some problems. I have tried searching the forum, but can't quite find what I need or answers were sent via PM so I can't see the resolutions.

Problem 1:
Helical interpolation - I get the "Alarm 021 - illegal plane axis command" despite the format of the G2/G3 movement looking correct and G17 active. I see talk of this being either a missing option or just a parameter change and need to work out which is the case for me. All threads I could find on this ended in a secret pm!?

Problem 2:
Jerky movement is 3D surface machining - I need to use High Speed Machining (G05 I believe?), but the controller does not recognise it? Does this mean I don't have this option or just another parameter? How can I find out?

Any help would be very much appreciated!

Best Regards
Aussie CNC
