Stumped with 7i76e and cheap 500W spindle wiring

Hello,

I am new to Linuxcnc and thought I would get my feet wet with a simple cnc router build.

Motion is working mostly fine (not sure on the dual Y yet but all motors move) and I am having trouble with the wiring to TB4 to the spindle power supply.

The spindle power supply has 2 choices for speed control, 0-10V or a potentiometer which is also 0-10V. I also have a relay I want to tie to enable to fully cut power to the spindle.

TB4 PIN 1 - Spindle power supply potentiometer 0V (GND)
TB4 PIN 2 - Spindle power supply wiper
TB4 PIN 3 - Spindle power supply potentiometer +10

TB4 PIN 6 - relay board ttl input.Relay board to spindle power supply On/Off

If I attach the supplied potentiometer and jumper the on/off terminals I have speed control of the spindle. If I wire the above linuxcnc seems to show it is enabling and supplying a speed voltage to the TB4 pin 2. I do not seem to be getting a voltage on TB4 Pin 2 and nothing on TB4 Pin 6 Spindle Enable+

Any suggestions would be appreciated.

Does TB4 pin3 measure 10V relative to TB4 pin1?
Did you look at the 7I76 spindle hal pins with halshow?

Note that the ENA- and ENA+ pins are just the two connections of a switch
they do not supply any voltage

Pins 1 - 3 read 10V, pin 1-2 reads 0V. Hal was built with pcmconf and has configuration for the spindle. I changed one entry while testing as per a different post where the pcmconf makes a mistake. Attached hal and ini.
In linuxcnc I opened Hal meter and monitored Spindle.On,Spindle.forward and spindle.out. Spindle.out was as per the rpm setpoint. My spindle is 12000 rpm and I am not sure how to properly set the scale as of yet.

I will change the relay to include GND to ENA- (relay board is set to active low), thank you for the help

net spindle-enable => pid.s.enable
.......


net spindle-on => hm2_7i76e.0.7i76.0.0.spinena
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
should be:
net spindle-enable => hm2_7i76e.0.7i76.0.0.spinena


# ---setup spindle control signals---

net spindle-enable <= spindle.0.on

Thank you very much for your help. It is all working now.
