Post-Process failed due unknown reason

[MathieuHebbrecht]

Hi all,

It been a while since I needed your help to figure something out. Before I start I'd like to thank all of you for looking into my issue and helping me out.

I'm preparing a workpiece in foam. I have long each end mill so I can reach up to 45 mm. The overal length is quite long, I needed to alter a few parameters regarding retract en lead in heights. And now it won't compile and it generates post process files with .failed at the end.

In the file it refers to a log which I cannot find. So that was very helpful. 😕

Attached you find my drawing, can anyone take a look at it and tell me what is going on. I don't have a clue.

Also, I'm seeking some tips and tricks to mill foam. My current toolpath is very time consuming. Since it is foam I think I can go faster, only I don't know what I can do to make it go fast (apart from the feedrate of course)

FYI, post processor I'm using is UCCNC (for my step craft 840 CNC machine)

Thank you!

It's because you have coolant set to "Air". Do you actually have an M-code activated air blast, or is it manual? When you select each coolant type, it's looking to spit out an M-code that will control it. If you DO have one, we can modify the code to output the proper "M" and not simply fail

Wouw Seth, that was fast!

It was indeed that setting, didn't thought of it. How did you find it? By looking at the log? If so, where can I find the log?

When I posted it out, it was right there:

It "should" be at the location you were trying to post out to. I've heard of people not being able to find the file, not certain if there is a common denominator with them though, perhaps you are on a Mac?

[MathieuHebbrecht]

Yes, I'm on a mac...

Can you search to where the good code should have landed and see if it's there?

@innovatenate, I seem to recall the popping up before where the .failed.log didn't end up where it should be. Suggestions?

Mine are all showing up in the same directory that the NC file should be in. I tried looking around for an alternate directory, but didn't come up with anything. One solution may be to use Microsoft Process Monitor to record what is happening during the post process. Thes should allow you to capture where a file is getting written to (if its not showing up in the expected directory). 

Thanks,
