Bug Report - Missing G69 in Hurco Post Processor (Autodesk Fusion Library)

[laromosrl]

Hello,

I would like to report a malfunction found in the Hurco post processor available in the official Autodesk Fusion library.

Specifically, at line N49877 G0 B0. C62100., the machine returns an error.

At this point, a workplane transformation defined with G68.2 is still active, and no G69 command has been issued to cancel it. This results in a machine control error, as the repositioning command B0 cannot be executed while the tilted plane is still active.

The correct sequence should include a G69 command before repositioning, to deactivate the active plane transformation.

Request: Please check and correct the post processor so that it properly outputs G69 after each use of G68.2 and before any movement command that implies a return to a standard plane.

I kindly request the necessary modification to the post processor.

Best regards.

Hello @laromosrl ,

Thanks for your feedback! You are right, I just checked and found that it is an issue in the current library post.

I've fixed the problem in the attached postprocessor. Could you please try it to see if it solves your problem?

I will also update the library post with the necessary changes, the update will be available next Monday.

Thank you!
Achim

Yes, the post now correctly generates the G69 code.

Thank you.
