Probe Basic Help

wow, ok that was way easier than it should have been. all I ended up doing was deleting all the HAL files I had under [HAL] in the ini file, except the postgui_halfile and the one from my axis file. and it fired right up.

Thank you everybody!

EDIT:
After getting it running I noticed there are so many features. Thanks to everybody who worked on this GUI it really does enhance the linuxCNC experience.

a few questions. 
1. after changing to incremental jog mode, how do you get back to continuous jog mode?
2. how do I connect the spindle encoder to the "DRO" on the GUI? my pins are all there in the HAL file, but im sure there is another file that needs one or more of the hal pins
3. when I am setting up my tool table and touching tools off, I have seen many people use the spindle nose as the reference, that being the case - Why do they do this? does my G59.3 have to be the machine home coordinates, otherwise itll miss the probe? what is the purpose of having the nose being the first thing you touch off?

a few questions. 
1. after changing to incremental jog mode, how do you get back to continuous jog mode?

in the ini:

INCREMENTS = JOG .1in .01in .001in .0001in

having the JOG entry in the increments ini line adds a jog button that is built into the increments widget. see the below thread for anything else you may have missed!

2. how do I connect the spindle encoder to the "DRO" on the GUI? my pins are all there in the HAL file, but im sure there is another file that needs one or more of the hal pins.

The darker (left side) spindle rpm dro in the lower main panel is the actual spindle speed taken from linuxcnc "speed" status. in the gui it is pulling data from linuxcnc STATUS: spindle.0.speed and is a float value.  you should be able to connect your hal to feed this.  you can see the dro widget rule for the readout below as well as the docs link to set you on the path on how to accomplish this:

The spindle nose creates a repeatable gage line that all tools are offset against.  because this never changes it ensures that all the stores offsets remain accurate.  once the height has been established and stored in the touch off settings  on the offsets page as (SPINDLE ZERO), you should be ok providing your tool setter is permanently mounted and your home switches are accurate.  if they are not, you should remeasure the spindle zero height and enter prior to measuring new tools all while in the same running instance of linuxcnc.  G59.3 is where the tool touch off position is stored.  this is done so the user can see and verify the stored position in the offsets table.

the purpose for using the spindle gage line verse using the probe as a master tool, is to avoid those with large tool libraries having to remeasure all tools if the probe is crashed and a new tip installed which will effect its new tool length and as such any tools measured against the previous length offset of the probe.  by the probe being a single tool with its own offset against the spindle nose, if it is changed and updated the new offset will still be accurate in relation to all other stored tools.  this is the best way "in my opinion at least" to accomplish keeping everything consistent and compartmentalized to eliminate globally impacting the tool library in the event of a mishap.  if this isn't the way you would like to have the touch off, the macros i wrote are in the subroutines folder and can be rewritten to suit.  the button is tied to the macros file name and the other entries can be manipulated in the subroutine as you desire.

hope this helps!

im not exactly following what youre saying here, in the pyVCP on a normal Axis GUI the hal pins
"net spindle-vel-fb-rps         =>  abs.0.in
net spindle-vel-fb-rps-abs abs.0.out"

are assigned to

" spindle-fb-rpm-abs-filtered       =>   pyvcp.spindle-speed
net spindle-at-speed        =>    pyvcp.spindle-at-speed-led"

and that shows up in the VCP.

do I use these same pins and just assign them to different values? or am i missing this completely?

sorry misunderstood, thought you were editing the gui itself for your desired needs.. here is an example of the spindle section hal from my machine, should help!

our hal files look to be almost identical but im still not getting and data to the Probe_basic DRO for the spindle.

i feel like my connection between the correct hal pins and what you showed me earlier is not correct.

here is my hal and ini file.
