Error 021 Fanuc with generated NC code from Edgecam

Hi,

I generated codes with Edgecam, but I get the Error 021 Illegal plane axis from the machine. It's on Fanuc 18i-MB.

This is part of the generated code:

Hope someone can help me with this.

Thanks

On what line do you get the error, if it is after the Z2.0 at the start then the machine does not like the G17 code. The G17
is on the same line with the J0.0 and the J is for the Y-axis different than the G17 call out?

You have some serious problems in this post. Do you know how to modify the post? If so you need to sort out the plane switching and arc commands. If not, get a professional in.

I get the error after the z2.0 indeed. Could it be that K in the G2 code? G17 is just XY-plane if I'm correct.

What do you mean with problems in this post? Is it the actual thread or do you mean the code?

I have to agree with Steve, your post has lots of problems. Or the coordinate system setup? The program is cutting in the x,z plane?

It starts with a movement in xy and z plane with a helical movement and then going to only cutting in the xy-plane

It is not a 3D arc. It is helical motion. So, K-word in G02 block is not correct.

Thank you, that was the solution! I found an option in the postprocessor to turn of the 3D arc. I had to turn on "Suppress Pitch in Helical Moves" in the options

Hope it helps others too.
