Trying to move from UCCNC to Linuxcnc and using 7i96s but having trouble

Good news.  Having some success.  I have xyz moving and i have spindle brake and mist toggling on and off in halshow(which i have learned to use); I even got my mist working but grok says i have it backwards and i hope i have not damaged the board because wired 24 v + to solenoid    and solenoid - to output +    and out - to   ground.  It did not work when i wired it solenoid - to out - 

I have a huanyang gt 7.5 kw vfd  it is different from the non gt and its pins i had been using with uccnc are
s1    s2   grnd(may have been +10 the wire pulled off as I was looking at it)  Ai1 and comm     I am going to the shop soon and will post my files I will see if i get any led light on the board when I m3 if there are any.  Is there someone else who has wired a gt vfd that could tell me what worked for them.  Also ready to do encoder wiring. what pins would those be? Thanks in advance and i will be posting soon.   In uccnc  I had a custom button to put the spindle brake on when changing tool because i have a quick change nut on my Bridgeport series 2.

Got it .  Spindle running and all axis running now just need to tune axis and get limits and encoders set up this is amazing after so many days I think this is going to be worth it because I have more of these conversions to do and I have learned so much it is amazing.  Without even tunning the spindle is behaving really well with no feedbac yet.  I was having trouble in uccnc wtih overshooting and taking awhile to get settled.  Has anyon e noticed smoother operation with linuxcnc vs other s when they switched?  The exciting thing for me is the prospect of ridgid tapping.  .  My liimit switches are only two wire.  Is this going to work?  I have a threee wire home swithc set up hall sensor

Yes, many of my clients and friends, that is the first thing they notice when the machine starts moving after switching from Mach.

My liimit switches are only two wire.  Is this going to work? 
 
Yes.

I have a threee wire home swithc set up hall sensor
 
Might be to late but, LinuxCNC can use a single switch for Homing and min/max limits, per joint/axis, so you do not need separate switches for limits and home.
3 axis machine = 3 switches total <<<< example
You can also use any combination of switches as you need/want.

If you have the limit switches, keep them. It does make for a safer machine. I used seperate min/max/home on my first machine but my next one I used a combined home/min limit switch only with no max limit.

I have been trying to get the encoder working for the past 1.5 days.  It is an amt102-v  5 wire a b index.  It worked well in uccnc but all i get when m3 is at speed light comes on.

Can you post your current hal/ini files?

There are basic steps to verify encoder operation

1. Run halshow

2. Select the watch tab and then the 7I96S  encoder position pin and verify that it
increments by 1 for each forward turn of the spindle

If not you need to check the scaling, encoder connections etc
