Simulate g-code toolpaths from external CAM?

[Russ4262]

Harvie,
Thanks for checking back.

Any news on this?

I see the bug report created by

@Sliptonic

is still in the Mantis bug tracking system. I don't know what progress has been made since last summer.

Honestly, I think developers have been working on other transitional issues related to Qt 5 and Python 3 updates. I do know @Sliptonic is still hard at work on the PathWB tool set in general.

We'd be glad to have you code with us.

Hi guys. Have you looked again into the simulating of 3rd party g-code?

Update: ah sorry, didn't noticed there is second page of comments in this topic

It's funny you mention this as I started looking into it last week.

I Will fix the segfault, but the main cause is because there is an operation without any tool assigned.

When i don't use preprocessor, the g-code gets imported but nothing else happens. So i tried with latest 0.19-development appimage, and when i used the "pre_gcode" preprocessor it looks like it's trying to create some job using the g-code, but it ends up giving some python errors and the import fails.

You should definitely be using 0.19. Create your job first then try to import using the gcode_pre. This hasn't gotten a lot of testing so bugs are possible (likely). Please paste the python errors. If it's a long backtrack, create a pastebin and paste the pastebin link here.

news on other fronts;

I've been talking with the camotics people about improving the integration between camotics and freecad. I've done an initial experiment using their camsim command line tool. There's a branch on my repo here: https://github.com/sliptonic/FreeCAD/tr ... e/camotics
With it installed, you get a new button on the toolbar if camotics is installed. Select a job and press the button and it will do the simulation externally and import the resulting .stl mesh to the freecad project. This is a first step. Next, we'll look at building a proper API that FreeCAD can talk to a running camotics instance through.

So cool!

Please paste the python errors.

I just tried to import g-code again using gcode_pre. using latest development appimage on archlinux. and it printed following error:

Code: Select all

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/tmp/.mount_FreeCAQiabq6/usr/Mod/Path/PathScripts/post/gcode_pre.py", line 118, in insert

<class 'NameError'>: name 'QtCore' is not defined
Traceback (most recent call last):

When using <none> preprocessor, the import does not fail.

latest development appimage on archlinux.

That isn't a version. Please paste your FreeCAD info.

Please keep an eye on this PR: https://github.com/FreeCAD/FreeCAD/pull/4477

I am trying to open gcode file. I'm starting FreeCAD from AppImage, then select "File->Open", located gcode file and clicked the "Open button". Next I select pocessor "gcode_pre" and clicked the "OK" button.

As a result I get an error message box saying:

Code: Select all

'NoneType' object has no attribute 'sendMsgToViews'

Also there are error messages in FreeCad's Report view:

Code: Select all

23:24:30  Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/tmp/.mount_FreeCAjsga5o/usr/lib/python3.10/site-packages/shiboken2/files.dir/shibokensupport/feature.py", line 139, in _import
    return original_import(name, *args, **kwargs)
<class 'ModuleNotFoundError'>: No module named 'gcode_pre'

  File "<string>", line 46, in <module>

What am I doing wrong?
