I don't understand this error, can you help?
Attachment 491236
Is because is in line with G80 or M09? Should I modify my post processor?

You don't appear to have a feedrate programmed, G00 is blockwise I think so won't work in next line.Quote:

If I add G00 or G01 before Z in that line it works without F.Quote:

So I guess I need to modify my post processor.
Or, it is safe to delete that Z on line N93 completely because at the end of peck drilling it is exactly on that Z height at witch is starting? (N8 G43 Z25. H01)
To answer myself, yes it is safe.
The question is why PlanetCNC is bothered by that Z there, if it is standard on Fanuc?
We don't need to reinvent the wheel.
Because NIST RS274/NGC G-code standard clearly says that "It is an error if axis words are programmed when G80 is active".
Did it move to the Z25. position then to the Z0 position, ??? if it did then G98 is moving it to that Z25. position and the G53Z0 is moving it to the Z0 position.Quote:

This is not standard for Fanuc format; this has just been made by a postprocessor that someone has created.Quote:

Yes, it move to Z25, the next Z0 you refer is G53 Z0 so it will be in machine coordinate. (upper Z position)Quote:

I was just curious why it is not allowed to have that Z move, and PlanetCNC already answered to that.
Yes, that is the best thing to do, the Z25. was a redundant any way.Quote:

N22 Y10.25 ( After this last move had finished it would move to Z25. because of the ( G98 ) in the first line of the canned cycle.)
