Create CNC Job from a Excellon Object

[Daniele Fornaciari]

Hi, on a Mac OSX 10.14.4 using Python 3.7.3 I have the follow problem: when I try to create a cnc job for drill from a Excellon Object nothing happen and in the status bar the follow text: "An internal error occurred. See shell"

in the shell:

[DEBUG] Using OR-Tools Basic drill path optimization.

This is the result of a file created inside FlatCAM (that I attached: newest_edit.DRL), but the same happens with an exported file (Gerber_Drill_PTH.DRL)

I tried the same also on a Windows10, but the same happens.

How to reproduce: download file, import in a new project select one and than select "Create GCode" Button

Hi Daniele,

I believe that the issue is related to a change that Google OR-Tools has done in the latest version (the API was broken) of their package coupled with the fact that just before the release I've done the upgrade without further checking.

I have already upgraded the affected part of code and the issue is solved and it will be available in the next version, 8.915. For now, the 8.914 x86 windows installer is working properly as it does not use the Google OR-Tools but a simple Travelling Salesman algorithm for drill path optimization. BTW, I did opened the file with no issue in my working version (which is not ready for publishing yet).

Best, Marius

Thanks, when you’ll push I will try it from Beta branch, so I can go forward with my project.

You can safely use the 8.913 version until I finish what I’ve started for 8.915. Use the provided file bundle instead of cloning the beta branch if using it in MacOS.

Solved in FlatCAM 8.915
