Hey guys! Me again...

after the last thread I made I've been using Probe basic and been loving it, even made a few parts and had no issues. until today I figured I would actually set up my tool setter and touch probe since that is the whole reason I switched to probe basic in the first place. but have ran into a strange issue that my google-fu has not been able to bring anything up on. 

I'm just trying to probe the spindle nose on the tool setter, but when I send the command to perform the probe the Z axis doesn't move. The DRO starts counting off as if it is moving but nothing on the machine is actually moving and pressing the tool setter manually with my thumb for example also does nothing and then after a few seconds the machine says that it never triggered the probe (Obviously)

Just wondering if anyone has experienced this behaviour before? and where I should try to look and what I should be looking for? I'm getting ZERO error messages it just doesn't work :\ If I have set up the probe wrong thats fine I can trouble shoot that later but it seems odd that the machine never even moves to find the probe but the DRO thinks the machine IS moving...

Thank again for your wisdom guys.

not had this experience and probe daily on my machine running the latest version. sounds like your machine is not properly setup. if your configuration files are setup correctly according to linuxcnc docs and you are seeing probe input activation in halshow than probe basic only needs to have the probing and tool setting parameters correctly entered in order to function as expected. i would start with you config files and get that sorted first!

I'm not sure where I'm going wrong, My machine appears to be set up correctly because its working and not giving errors. its just not probing. 
I have tried to find people with the same issue and watched and read a few guides on setting up a probe with linuxcnc etc but the problem I'm finding is that everyone seems to be using a completely different set up and doing it in various ways that don't seem to work for me and it a lot of it is based of assumed knowledge. 

Below is my Config files if anyone could have a quick look and see if anything obvious stands out I would greatly appreciate it.

I have gone up and down the probe basic site trying to check my work but the only real mention to anything probe related is commenting out the (# net probe-in  =>  qtpyvcp.probe-in.out) in the post_gui_hal which I did and other people setting up Probes in other screens are adding custom xml files etc which I'm assuming is already pre built in? 

Thanks again.

More info, I've been playing around and figured out the probe triggering (as in switching states in HAL_METER from false to true) Just has a wire crossed over.

But the behaviour is still the same I press probe there is no machine movement but the machines DRO in probe basic starts counting down slowly as if the Z axis is going down. Only now I can trigger the tool setter or probe (I have them in series with each other as they are NC) and the DRO stops.

I've also noticed that no matter which direction I select to probe for example X+ direction probe, its the Z DRO that starts counting down, same if I click Z- probe or Y- probe or any of them.

net probe-in => motion.probe-input
net probe-in <= parport.0.pin-11-in-not

this should be all you need for the input in your main hal
