Need Help Setting Up a 2nd Spindle

I am trying to configure LinuxCNC for use on a rose engine with 2 spindles + 6 other axes.

Everything works for Spindle0 & the other 6 axes of movement (X, Y, Z, B, U, & V), however I cannot get Spindle1 to work. Any ideas would be greatly welcomed!

I've copied the key items I believe are needed below.  The complete versions of the HAL and INI files are attached.  (The include files for the spindles had to be renamed to be .ini for attaching them, but they are actually .inc.)

hal fileloadrt [KINS]KINEMATICS
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS num_spindles=[TRAJ]SPINDLES
loadrt hostmot2
loadrt hm2_eth board_ip="192.168.1.121" config="num_encoders=0 num_pwmgens=0 num_stepgens=8"

loadrt pid names=pid.x,pid.y,pid.z,pid.b,pid.u,pid.v,pid.s0,pid.s1

(other sections are also configured for SPINDLE 1, and are setup fundamentally the same as they are for SPINDLE 0)
 ini file[TRAJ]
SPINDLES = 2

# [JOINT_7]
# SPINDLE = 0
# TYPE = ANGULAR

[SPINDLE_0]
(this works as expected, so I've not added the details here)

[JOINT_6]
SPINDLE = 1
TYPE = ANGULAR

[SPINDLE_1]
(the rest is setup just as with SPINDLE_0)
 Side Note: Please don't refer me to RoseKins.  I tried that and it will not meet our needs.

The attempts to run the spindle are by using:

M3 S10 $0 <=== that works
M3 S10 $1 <=== does not work

# net machine-is-on => hm2_7i92.0.stepgen.07.enable

AFAICS, nothing sets hm2_7i92.0.stepgen.07.enable true so it can never run.

try removing the comment (#) :

net machine-is-on => hm2_7i92.0.stepgen.07.enable
