Hi,

Just to let you know. Cam has a deb installer for a few days now.
It's usefull for plasma, milling and laser machines.
The program can be modified with qt. For example add a save_file_as button somewhere.

github.com/grotius-cnc/cam/releases

As an FYI installed this per release instructions on Debian 11.  No menu item showing, even after reboots.  Also the command (assuming it is cam) is not being found in the command line search path.   Looks like it is installed to /opt.

Suggested additions to release notes:
1. make the sudo install commands that have a long list not have hard returns in the line.  I did a copy and paste and didn't discover there was problem until later as I had missed the errors that the second two lines were missing the apt install command as the copy/paste had treated the text as 3 distinct lines with line-returns at each end.

2. note where the install is being placed. That way if menu's don't appear you know where to look.  I just happened to get lucky that /opt was the first spot I stated hunting.

Still a great tool with a lots of potential to give a "simpler" yet powerful alternative to the likes of SheetCam.

As a side note, still not able to run under Debian 11.   Getting errors such as:
./cam: error while loading shared libraries: libTKPrim.so.7: cannot open shared object file: No such file or directory

Probably some search path issues but I have no idea where to start fixing it.

Cheers - J.

Hi Joco.

Ai. LibTkPrim is a opencascade lib. If you install this deb package it should work, normally :
github.com/grotius-cnc/oce/releases/tag/1.0.1

If not, you can follow the readme install instructions for build from source : github.com/grotius-cnc/oce

Still a great tool with a lots of potential to give a "simpler" yet powerful alternative to the likes of SheetCam.

It is certainly powerfull. I remember, i coded it in a few day's for you.
Currently busy coding something else, a boston dynamic dog.
But i will take a look in the near future to give it some
extra functionallity.

Thanks for your feedback.

I went back over the install instructions diligently.  Different error now.
./cam: symbol lookup error: ./cam: undefined symbol: _ZdlPvm, version Qt_5

So the libs are being found but something not right.  What version of QT5 am I supposed to be using?

Key system data:
    Qt Info
        Qt Version:     5.15.2
        Qt API:         PyQt5
        Qt API Version: 5.15.2

    System Info
        Description:    Debian GNU/Linux 11 (bullseye)

        Kernel:         5.10.0-9-amd64
        Version:        #1 SMP Debian 5.10.70-1 (2021-09-30)
        Ram:            4 GB

Cheers - J.

Hi,

This will install an extra qt in the /opt/ dir.
github.com/grotius-cnc/Linux-Pro/release...1.0.0/qt-creator.deb

Try if it's solved.

It could be that i compiled cam with CONFIG += c++20 is the actual problem for you.
That should then be c++ 11 to avoid any errors.

That fixed it. Must be the compile flags are too close to the "edge" :-)

Hello Joco.
Install your modified program, since it allows you to have entries when the compensation is in the computer, that is something that was missing in dxf2gcode, when I saw that the entries were graphed I got excited but when generating the g code, I observe that the entries are after the generation for example of a circle not be generated before? Could you help me please.

@ Grotius
I want to use dxf2gcode for plasma cutting, I'm using qtplasmac, and I want to implement some features such as reducing the speed to 60% when cutting circles, I know I can implement using <holes> but I only want to use it for circles and not for all arcs. Yesterday I made some test cuts with the new version where you can modify the inputs and outputs.
