G02/G03 X?Y?I?J?

[Bazzst1975]

Hi all, first time posting here, please be kind

 

Here's my problem:

when I run a program with G02/G03 X Y R, everything is fine,

but if I use the I and J code machine goes in "Alarm 21 wrong plane....."

The machine is a Kira 40HB with Fanuc 21 control.

This programs run perfectly fine on a Makino.

Change the programs to R would take alot of time, so if I can find the way to get the machine to read the I and J code it would be great.

I think, but I'm not sure, one o more parameters need to be switched on to enable the control to read the I and J code.

Any help please will be very much appreciated.

 

Cheers

Do you have a G17 callout before your first

G02 or G03??

Assuming your using Mastercam, since you are on a Mastercam forum, why dont u just change the output in the Control Def. to output Radius (under 'Arcs') instead of Delta to Center...? Easy fix, repost and done.

 

Welcome to the Forum!

My guess is he has a proven Makino program he needs to run on the Kira

Guys,

Thank you all for your posts.

 

Yesterday when I came across the problem I didn't have time to look at it carefully.

 

I tried a few things today and found that actually the problem is different.

The machine read without problems I and J codes in G02/G03 cycles.

 

The problem is it doesn't aloud a Z movement in G02/G03 mode. This even if I use the R code. And that's what my programs do.

 

The alarm is "021 ILLEGAL PLANE AXIS COMMANDED"

 

Yes gcode I do have G17 at beginning of program.

And yes, those are proven jobs on a Makino that I now need to run on a Kira. The Kira machine is a 3 axis horizontal with an index table.

I think the machine is capable to execute a Z movement in G02/G03 and it would save me lots of time avoiding to repost the progs.

But maybe I'm wrong??

To be more clear,

 

here's part of the program:

X119.829Y-30.36

Z1.

G1Z0.F800

Y-26.64Z-.314F2200.

G2X112.014Y-26.568Z-.994I-3.829J8.64

The machine should be able to machine a helix.

You might want to talk to the manufacturer

or review the paramter settings in the control.

Helix arcs may be disabled.. It may just be a

matter of changing a 0 to a 1 in a machine parameter.

Thanks gcode.

That's what I think too.

Been putting pressure to the manager to get in touch with the dealer were the machine was bought, but not getting much help.

 

Would you know whic parameter # please?

not a clue.... there are thousands..

You need helical interpolation option

[Bazzst1975]

Thank you very much guys,

 

it's all sorted! :-)

Hey Bruce, how you going?

 

yeah mate, good old F....
