This could be done in ClassicLadder, I have a Lathe Turrent example you might want to look at.
gnipsel.com/files/linuxcnc/configs/cl-turret-sim.zip

Or as I mentioned above use parameters to select the tool.

For example if T6 is issued then iocontrol.0.tool−prep−number has the value of 6 and you can test that 12 times to see what tool to load.

Thank you to again!

Could you give me an example of how it should look like? It's pretty hard to understand, how I need to set it up.

For only one tool would be enough- just to have a line where it has to go.

Thanks guys!

Using a remapped G-code
Code:
.... (Whatever preparatory unload code you need) (The following (DEBUG, are to check if the M6 is good or bad here) (DEBUG, before M6 the param is #<_selected_tool>) M6 (this sets an internal parameter to the required too number) (DEBUG, after M6 the param is #<_selected_tool>) M64 P[ #<_selected_tool> ] (fire the solenoid corresponding to the tool number) M66 P[#<_selected_tool>)] L1 (wait for the corresponding "loaded success" pin M65 P(#<_selected_tool>) (retract the changer) .....

Thank you for the fast answer :-)

So lets say,

Tool 01 = P01
Tool 02 = P02
....
Tool 12= P12

Is that they way I have to set the pins in the postgui?

Thanks all :-)

It doesn't need to be postgui. You can do it any any HAL file after motmod is loaded.

First you need to make sure that you have enough DIO pins:
linuxcnc.org/docs/2.7/html/man/man9/motion.9.html
(note the "num_dio" parameter. You need to change this in the main HAL file, bit that's OK, I think you can accept that you are finished with stepconf / pncconf now.)

Now connect the hardware inputs and outputs for P1 to motion.digital-in-01 / motion.digital-out-01 and so on

Then realise that I messed up, and almost certainly should have used #<_selected_pocket> in the G-code sample :-)

Ooookay, I'll give it a try.

I will upload the files after the test, hopefully I understand it all :-D

Sorry for all the questions, but I'm all new to linuxcnc.

Thank you again!

Just did a quick test for #<_selected_tool> vs #<_selected_pocket>
When no Tn has been issued 0.0 and -1.0
After a T1 has been issued 1.0 and 1.0

Why use selected pocket for a non random tool changer? But I guess it will always be the correct number... so long as the -1.0 does not cause a problem in the G code.

I created a simple subroutine from your steps on page 1, I don't see where the tool number is called? Can you put that in the subroutine? I just opened a show hal configuration watch window and added the digital output pins so I could watch them turn on and off.
Code:
o<toolchange> sub ; Where do you change the tool by number??? M64 P0 ;1. Unclamp tool G4P1 ; Pause M64 P1 ;2. Move down the tool-basket G4P1 ; Pause M64 P2 ;3.Spindle clean with air G4P1 ; Pause M64 P3 ;4. Move all tool arms up one output that moves all up at a time G4P1 ; Pause ; After you move them up do you turn off the output??? S200 M3 ;5 Spindle on at about 200 RPM while inserting a tool G4P1 ; Pause M65 P2 ;6.Spindle clean off G4P1 ; Pause M65 P0 ;7.Clamp tool G4P1 ; Pause M5 ;8. Stop the spindle G4P1 ; Pause M65 P1; 9. Move up tool-basket G4P1 ; Pause ; 10. DONE o<toolchange> endsub M2

Hey guys, sorry for the late reply!

What should I say?
Everything works just like it should, i am so happy, that you showed me, that there es another way to do it.

I will upload the subs tomorrow, maybe they can help someone some Day.

Next step is setting up all Switches for override and axis selection.
I will create a New topic for that, it must be done with mux...

Thanks All!
