5X post issue

[gcode]

I'm running a 3+2 high speed core ruffing toolpath

on a hugely expensive piece of titanium.

The post is a modified X3 gen5X.

I have the tolerance page set to default settings

and I'm getting random K-.0001 in the code

with no coresponding Z so the control is alarming out.

Any ideas,

I'm thinking I need to tweak a torlerance setting,

but this is not the time and or part for experiments

 

This is 3X code on a 5X plane

Tom, it looks like it is throwing G18/G19 plane code (K value)in with the G17 plane arc. that would bother me more than the alarm. Not quite sure what would cause it tho. Do you need XZ or YZ arcs? You can disable in control def... should get rid of the K.

Just thinking out loud..

[gcode]

Spooky stuff.. a 2" high feed, 10" deep

in a 30 x 20 x 8 block of TI is no place for an arc error..

We shut off XZ and YZ arcs.. code looks better

The operators are still jumpy though

That is a big hunk to be proving a marginal post... Looks like we gots two crazies here.

Hope it works out for ya.

have you tried posting using a different post and see if results are same/different?

[gcode]

I tried both my double rotary posts and got the same results.

I've been using this post for three years..

building it over with a new gen5x with every release.

This is the first time I've encountered this problem and its unique to one toolplane in the

file

Just curious, when you right click in your view manager and select info, what kind of matrix numbers do you get for top plane?

Should be all 1's and 0's.

[gcode]

The Top Plane is OK.. and we're running this

style of toolpath in a half dozen different planes

Only one is causing problems.

We disabled 3D arcs on the transition page and it solved the problem.

Hey Tom,

How is that Highfeed working in Ti with that kind of stickout? What kind of speeds and feeds can you get and depth of cut? We have a deep pocketed Ti part here I am trying to get them to try one.

 

Thanks,

Corba did some highfeeding on Ti 10-2-3. 9.7 gage length with 2" dia. We were doing .041 per tooth .045 depth of cut with 220 sfm.
