Spindle Tool

In your screenshot current_tool is set to 2, but tool_altered is FALSE, so iocontrol has not had a signal that the tool number has changed.

The first update of current_tool, when the toolchanger is initialised, will prompt iocontrol to set the tool number to that value, so as to initialise Linuxcnc and Axis.

Thereafter you must send a signal that the tool number needs changing, by setting tool_altered to TRUE.

You will have to add a bit out pin to your component to do this

Have another look at post 28183 on this thread for the logic in a bit more detail

Just noticed

I set the tool in post-gui.hal net Spindelwerkzeug => iocontrol.0.current_tool

The net command links a SIGNAL and 1 or more pins

HAL will create a signal called Spindelwerkzeug and link it to iocontrol.0.current_tool if this is what you input.

Should be net new-tool-signal Spindelwerkzeug => iocontrol.0.current_tool

OK

I will try this tomorrow

Hello ArcEye,


I'm right back from testing, and it works.
thanks a lot. Hopefully it will implent in the next Linuxcnc version also.


hello andypugh,

i saw the different, hopefully this will not be a problem?

Thanks for your help

Glad it works for you, I doubt if if it will be adopted for all the previous reasons, but it is open source so we can go any route we choose to.

The standard variable separator in C is an underscore, largely because it cannot be confused with a mathematical operator.
Also programmers are lazy and all the constants which are upper case can easily be written with the shift depressed.
Whatever!?

Hello ArcEye,

the last days I had off.
this still works.
Many thanks.

Hope we will found a solution withe the coming new version.
But one question.
When I do Txx
then some lines work
M6
the tool will change.
But how can I see the tool is selected?
I mean the tool number and a strobe signal?
My next project may be a chain toolchanger, and i want to move the tool from the chain ( this needs a while )
and when M6 occurs just change.

Hi

Glad it still works for you.

It is quite common in large machines to have complicated and quite slow tool carousels and for the next tool required to be prepped in advance by a Tn command

The default connections for hal_toolchange as set up by stepconf, just connect iocontrol.n.tool-prepare to iocontrol.n.tool-prepared, effectively bypassing the preparation stage.

You just need to separate these and connect to your component. When the tool-prepare signal is received, tool-prep-number holds the tool number to be prepared.
Do what ever you need to to get this tool ready for the next toolchange and then set the tool-prepared signal TRUE, to signal you are ready.

The attached screen shot shows a sim where I have your iocontrol binary in use

I changed to Tool 1 by setting iocontrol.0.current_tool to 1

I then did a MDI command 'T2' and you can see that tool-prep-number is now 2.

Hopefully that explains it.

Hello ArcEye

today I find a big Problem.

some times it will do no toolchange and the G-Programm will continue.

I tested now in MDI T12m6
and nothing changed in the io controls.
Any ideas?

Sorry,
I changed the toolchange.comp anf forgot the signal tool_altered

Thanks
Thomas

No Problem - if I don't write it down I forget everything!
