7i96s, 3 axis mill conversion, servo spindle, probe basic almost full function

Hey guys. I wonder if someone could assist me in nutting a problem in my configuration. I know the layout of the config has more than one problem, and i plan to learn better how to fix this myself, however as long as i have the axis' dialled in and the servo spindle controlled through the software i am a-ok with not having spindle orientation and extras setup until I better understand the Hal configurations. 

I have been running Probe Basic as a 3 axis stepper driven mill configuration, 3 homing switches for a year using the standard mill motor spindle and that has worked fine. I have just installed a Servo Motor to drive the spindle and now for some reason I am getting a joint following error when homing any axis. 

I have had the servo spindle working in a test file, (both Axis and probe basic GUIs),but when combined together in the previously working Probe Basic config I have issues. 

I have a feeling it might be something that is related to the post-gui file, as in an attempt to chase errors I was getting I have consolidated a not task that was conflicting, and I have reached to end of my limited knowledge.

I am working regularly to better understand the control flow within linuxcnc, but for now, if i was just able to get a minimal running configuration sorted I could at least use the machine whilst i gain that better knowledge. 

Thanks very much,
Bruno

Seems i have found a fix, for now. In my ham fisted attempt at merging a basic 3 axis Probe Basic configuration with a config containing a  step/dir driven servo for use as a spindle  I had left out the following... or at least a number of the following things 

addf pid.x.do-pid-calcs       servo-thread
addf pid.y.do-pid-calcs       servo-thread
addf pid.z.do-pid-calcs       servo-thread
#addf pid.s.do-pid-calcs       servo-thread
addf spindle-pid.do-pid-calcs       servo-thread
setp [HMOT](CARD0).dpll.01.timer-us -50
setp [HMOT](CARD0).stepgen.timer-number 1

I have attached the quickly update HAL and will work on making it less of a mess and more readable before asking a couple more questions about the possibility of getting spindle orientation working. Have been working on the HAL tutorial and had halcmd up and running with the -kf parameter to show where all my signals are linking to, so will attempt to become more conversant in what is happening with the configuration i have chopped together Thanks
