qt_dragon_hd - manual tool change and remap

How does one disable hal_manualtoolchange and where would I find damnu-cnc.hal?  I'm trying to work my way through a similar issue, but I'm very new to this.  I can get myself to where the t1m6 command moves to my change position spot and triggers a, "tool changed?" pop up.  Next it goes to where my tool setter position is and starts moving the spindle towards it.
 
From there though I can't trigger the tool setter.

Do you have an automatic tool changer? Other wise you need the pop up dialog so you can change tools.
Or are you talking about disabling AXIS's manual tool change program so you can connect to QtDragons pop up?

Sounds like the toolsetter electrical signal is not being detected by linuxcnc.
You should be able to use halmeter or something like it to confirm that pressing the toolsetter changes the motion.probe-input pin.

damnu-cnc.hal is a file particular to Suspension's configuration - yours will be called something else.

I don't have an automatic tool changer. I don't know if I'm trying to disable AXIS's manual tool change program, but I've just read that I need to disable hal_manualtoolchange.

If I enter t1m6 get the spindle to go where I want to change the tool and then make the change. I get a pop up that asks me to make the change. I select ok, and then the spindle heads to where my toolsetter should sit and starts traveling in the -z to make contact.

I'm currently doing this without any actual tooling in place and am just triggering the toolsetter to get some kind of response. That's not happening.

I too think the tool setter's signal isn't reaching linuxcnc but I'm not sure how to use halmeter to confirm it. If I select motion.probe-input pin (which says 'false') should depressing the button move change that to true? Currently it does nothing. Should it be defaulting to true and the pressing returns a false? I've used a voltmeter to check that the normally closed toolsetter does in fact open when its pressed.

I've included the following in my HAL file:

net probe-in => motion.probe-input
net probe-in <= hm2_7i96s.0.inm.00.input-09

And I've triple checked that my signal line is going to that input.

Thank you for any input

use halmeter to watch the motion/probe-input
Should normally be false.
Press your tool setter with your finger - halmeter should now say true

I'm assuming you are using a switched type tool setter not a electrical contact one ('touch plate').

Also if you could post your config files...

I'm using a switch type toolsetter.

I switched the polarity of the wiring from the diagram that came with the toolsetter, and now my halmeter for the pin sits at true, turning to false when I press the button. This is progress, it used to do nothing but stay false. It was contributing to my confusion with the halmeter as that was the first time I'd used it and nothing was happening when I pressed the toolsetter.

I think this has resolved my current issue. Stay tuned for tomorrow, when there's something else I can't figure out how to do.
