gCode Export Failure: "Error: Machine can only run metric parts"

[joeltbennettuk]

Hi. I have a strange issue here, I'm doing some CAM work for someone and they gave me a post-processor for their machine to work with, so I created a new machine for it and now when I'm trying to export gCode files with the Post Process, I'm getting ".failed" extensions on my files.

Here's a sample code output for one toolpath export attempt:

What is this? Am I being dumb?

Hi @joeltbennettuk 

It seems like a modified post could you attach the post file here . let me take a look at it

[joeltbennettuk]

Hi - I am attaching the cps file I was given to work with, and also a manual for the machine in question (High-Z T-1000 or something).

Please let me know if anything else is needed.

[joeltbennettuk]

I'll attach a couple more files here from the project in its current state that may or may not be helpful.

[joeltbennettuk]

Sorry to be annoying, but I can't find this issue anywhere else - I can send you the entire project if that would help.

Hi @joeltbennettuk 

Edit the post and search for the below section

and change the codes like in the attached code

  switch (unit) {
  case IN:
    //error(localize("Machine can only run metric parts")); // Block this line in the post
    writeBlock(gUnitModal.format(20)); //<< Add this line 
    break;
  case MM:
    writeBlock(gUnitModal.format(21));
    break;
  }
}

Hope it will work now !! 
Sorry for the delay in reply I missed the queue

Yeah I suppose that'd be best - someone might be annoyed about this floating around 😉

[boopathi.sivakumar]

You might wanna check the previous thread again I edited it.

No need for the model🙂

[joeltbennettuk]

Works perfectly now, thank you so much. I'm just going to attach the corrected post-processing file here in case anyone else needs it in the future.
