Remap unused buttons to do manual tool release and rotate carousel (have ATC)

Hi,
I've got a wired probe that I keep outside of the milling enclosure due to the risk of coolant and chips getting into the cable hole.
I've got a 16 carousel tool changer, and have setup VERSA probe, the changes/touch-off's all work super, controlled via classic ladder.

Workflow:
-When getting setup to run a program
-I swap out the current tool for the probe tool, via air solenoid to release the tool, I do my probing and then remove the probe, .
-I also need to load/unload tools and I can only do that in one position on the carousel.

Ask:
Create 3 software buttons (instead of physical) to do: Tool Release (momentary), Carousel CW(momentary), Carousel CCW(momentary).
I don't use the following buttons (pretty sure I won't down the track either):
-Laser Off
-Ref Laser
-Tool Sensor
-Touch Plate
-Go to Sensor
-Ref Camera
And was wondering how hard it would be to: rename them, change to momentary get a hal signal for them and connect them with an "or" to move the carousel and release the tool. 
Ideally it would prevent them from being used if the spindle was running or it was in the middle of a program or a tool change.
I've been using sim_pin in a separate window to do this, but I'd like to drive it from the UI.

Thanks in advance,
Cam.



 

What version of linuxcnc are you using?

I'm going to guess 2.9 and qtdragon_hd.
please rename and add this file to YOUR CONFIG FOLDER/qtvcp/screens/qtdragon_hd/qtdragon_hd_handler.py
If something goes wrong you can erase/rename the file and everything will go back to the original.
You should get 3 momentary buttons and 3 HAL pin:
Component Pins:Owner   Type  Dir                 Value  Name  
702  bit   OUT                 FALSE  qtdragon.atc_ccw  
702  bit   OUT                 FALSE  qtdragon.atc_cw  
702  bit   OUT                 FALSE  qtdragon.atc_release

Hopefully that gets you what you need. 

Hi Chris,

Correct its 2.9.2 qtdragon_hd
Awesome thx for that will give it crack over the weekend and come back.

Cheers,
Cam.

Confirming the version is:LINUXCNC - 2.9.2-112-g54bca16afd
I downloaded, added it to the directory, renamed it to "qtdragon_hd_handler.py.new", renamed the old one to "qtdragon_hd_handler.py.orig" and did a soft link "ln -s qtdragon_hd_handler.py.NEW qtdragon_hd_handler.py"

It came back with the error below, a couple of things
-the file I downloaded is 54 lines long (not a checksum but incase it was chopped off)
-I'll give it a go without the soft link and see what happens

try without the soft link - just name the file qtdragon_hd_handler.py

I just had a play with the files and removing the soft links with no joy.
The only file in the directory containing the name "handler" is the new one you supplied.

So just to check I've done things right:
-downloaded the file from the browser (could use curl if that's an issue)
-moved the orig file out of that directory to a temporary spot (mv qtdragon_hd_handler.py ~/.)
-moved the downloaded file to that directory with the same name as the orig: qtdragon_hd_handler.py

Looking at the tail of the file I download doesn't look complete but I've not done any python - just started readying the doco.

please rename and add this file to YOUR CONFIG FOLDER/qtvcp/screens/qtdragon_hd/qtdragon_hd_handler.py

I think the file should have been copied into this directory:

Boom that was it!!
Buttons are on the screen, will have a go at hooking them tomorrow.

Thx all

Ahh Phill saw it right away!
Let us know how it goes.
