Tool Table was created by babinda01

Hi
I am playing around with a new GUI, and am fiddling around with the tool-table. My question is, can I add addidtional fields, that I can use within my gui, but which won't affect how LinuxCNC reads the table?

For example can I add the following enteries, without disturbing Linuxcnc when it reads the table in:
S10000
F300
M8
N7

Thanks

I assume you wish to save these entries to a file?
presently you would need to save these entries to a separate file.

There has been work to eliminate this limitation but nothing has been finished.

Hi Chris
Thanks for your help. I was hoping to be able to use just the one tool file, nevermind. I will write a master tool-table within my application and then create the LinuxCNC tool-table from that.

I have modeled most of my tool-table from a Siemens 828, and so I want to be able to set spindle info, feeds, coolant parameters etc within my table.

Regards
Andrew

Hi Chris
Thanks, the 2 tooltable method seems to be working for me. Attached is a screenshot of my first rough attempt which seems to be working.

beautiful!
Wanna build some widgets for qtvcp

i am not sure if you are referencing gladevcp widgets for your work (or if you are using python) but I will warn you if you use your tooltable to actually edit linuxcnc's tooltable file, you will want to add code to make sure the OS doesn't cache the data.

gladevcp uses this:

        # Theses lines are required to make sure the OS doesn't cache the data
        # That would make linuxcnc and the widget to be out of synch leading to odd errors
        file.flush()
        os.fsync(file.fileno())
        # tell linuxcnc we changed the tool table entries
        try:
            linuxcnc.command().load_tool_table()
        except:
            print "Reloading tooltable into linuxcnc failed"

Hi Chris
I suppose at about this point I need to admit/confess to being a "Windows Person", please dont think any less of me.

I am using a split screen (2 seperate monitors on the one pc) approach like the new Mazak, and DMG Mori CELOS controls (

).

I have used your GScreen basic tutorial to make quite a simple UI that gets displayed on the top Monitor, this ui is pretty well just Gremlin and the GCode window. The lower monitor is then displaying my app which is written in B4J, and which connects to the LinuxCNC python interface via websockets.
In this way I can have my tool setup screens, workpiece setting screens, probing screens etc etc. as well as a simple 2.4D cadcam system that I wrote quite some time ago.

As soon as its finished I will be posting most of it - possibly without the cadcam portion.

Regards
Andrew

That's a unique way of doing it. Cool!
I'm glad GScreen and the tutorial was useful to you.
I'll be interested to see a video or pics of your system.

Welcome to the dark side (linux) lol

We did develop a tool database schema (and as it is a database you can easily add extra fields)
wiki.linuxcnc.org/cgi-bin/wiki.pl?ToolDatabase
I got it working, but it never made it into a "real" LinuxCNC distribution.

I've seen your tool table database schema Andy. Its not something I need but I did wonder if it could not be ported to one of the python SQL database engines rather than using SQL Lite. This might offer a tighter integration to the LinuxCNC code base.
