When machining the part on the subspindle, there is a positive z

[StefansB]

Hello, why is there a positive z on the subspindle?

It is expected to crash!

Is it because I posted both sets at the same time?

What post processor are you using?

The Setup (in Fusion) for both spindles is the same, it's required that the post processor handle the inversion of the Z axis (and related arc moves). My Doosan Lynx is similar to your machine (as far as Z needing to be negative for retracts)

[StefansB]

I use Doosan postprocessor.

I don't understand how the setup should be the same and how, for example, can the arc movement be applied to the facing operation?

Could you share your Fusion file?

Already attached

oops, thanks. Didn't notice it.. 🙈

Are you using the generic Doosan post, or one of your own modification? Using the generic Doosan post, I'm getting this code (in the location indicated in your photo):

G1 X40.2 Y0. Z-1.766 F0.134
G0 X37.643
G1 X36.531 F0.1
Z0.234
X38.531 Z1.234

I am using doosan postprocessor with last update.
But look at the code below, there is Z positive.

What are you using for a machine? When posting out as a Doosan Lynx(with Y), I get the same exact code as what I posted above. Are you setting any user properties?

[StefansB]

I use on post settings safe retracts and home positioning.

Move to Z-home positions - WCS

Z-home positions 400

Right, well aware of the Simulation limitation. I was asking about which machine you were selecting here:

But your response above gives me the settings I needed to know. For now, I would avoid those settings. I'll get this logged and we'll update the post processor.

We've opened up CAMP-2693 to fix this issue. If you wish to continue using your Post Processor with the non-standard Z home positioning, you would need to edit your post. You can do this by:

1: "Comment" out the following lines in "onSectionEnd":

  /*if (getSpindle(PART) == SPINDLE_SUB) {
    invertAxes(false, false);
  }*/

(Notice how it has "/* and */ in there? That's what you need to do)

2: modify the following code in onSection (at line 2091 in the latest version).

  // invert axes for secondary spindle
  invertAxes(getSpindle(PART) == SPINDLE_SUB, false); // polar mode has not been enabled yet

Thank you for finding the solution and quick response.
