5i25+7i76 Spindle control issue

5i25+7i76 Spindle control issue was created by johnjsb
I can't seem to get the spindle working after a few days of wondering around the net. I had to jumper the enable pin on the spindle controller and the direction doesn't work. when i issue a m3 it turns clockwise looking from top of spindle(correct cutting direction). when i input m4 spindle stops with 0v on tb4-pin2. either m3 or m4 gives 5v on spindle_ena+ pin6 (which needs to be ground) and 5v on spindle-dir+ pin8(which needs to be 0v for ccw m4). m3 with s5000 gives me 9.07v at 5000rpm so thats good. Please help i think there needs to be more code here with some kind of -not or -invert somewhere.
here is my hal file:
here is my .ini as well:

Here are some links to what i am using for controller and the mill.

How is the 7I76 wired to the motor controller board?
it should be:
7I76 TB4 pin 1 SPINDLE- --> Motorcontroller GND
7I76 TB4 pin 2 SPINDLE OUT --> Motorcontroller AVI
7I76 TB4 pin 3 SPINDLE+ --> Motorcontroller +5V
7I76 TB4 pin 5 SPINDLE ENA- --> Motor controller GND
7I76 TB4 pin 6 SPINDLE ENA+ --> Motor controller START/STOP
7I76 TB4 pin 7 SPINDLE DIR- --> Motor controller GND
7I76 TB4 pin 8 SPINDLE DIR+ --> Motor controller F/R
it should be:
7I76 TB4 pin 1 SPINDLE- --> Motorcontroller GND
7I76 TB4 pin 2 SPINDLE OUT --> Motorcontroller AVI
7I76 TB4 pin 3 SPINDLE+ --> Motorcontroller +5V
7I76 TB4 pin 5 SPINDLE ENA- --> Motor controller GND
7I76 TB4 pin 6 SPINDLE ENA+ --> Motor controller START/STOP
7I76 TB4 pin 7 SPINDLE DIR- --> Motor controller GND
7I76 TB4 pin 8 SPINDLE DIR+ --> Motor controller F/R

7I76 TB4 pin 1 SPINDLE- --> Motorcontroller GND
7I76 TB4 pin 2 SPINDLE OUT --> Motorcontroller AVI
7I76 TB4 pin 3 SPINDLE+ --> +10Vdc Power Supply
7I76 TB4 pin 5 SPINDLE ENA- --> Floating didn't know it had to be used i thought these were just inverted signal

7I76 TB4 pin 7 SPINDLE DIR- --> Floating

so the 2 i left floating need to be grounded? i was under the impression they were outputs.

7I76 TB4 pin 6 SPINDLE ENA+ --> Motor controller START/STOP
7I76 TB4 pin 7 SPINDLE DIR- --> Floating
7I76 TB4 pin 8 SPINDLE DIR+ --> Motor controller F/R
so the 2 i left floating need to be grounded? i was under the impression they were outputs.

The 7I76 spindle enable and direction outputs are floating switches (optocoupler outputs). Each is a independent isolated switch so you always need to use both + and - connections of each.

It is worth bearing in mind that in the case of many of those mills (with the KBIC motor controller) the speed-adjust pot sits at +100V.
I _think_ that the Mesa 7i76 spindle control is happy with this situation, and that you probably don't need the SC2, but you would want confirmation from PCW on that matter.

I believe the KBIC controller is for the older model mini mill, never the less good info on that controller. i happen to have one around here that i was going to use for a lathe conversion so thats nice to know. This controller is a brushless controller with a add on board that gives a proper signal.
