Actually rather than link and unlink pins shouldn't the spindle selection logic
be done with logic components (like AND OR etc)

Yes, except that they only deal with bit values, not floats, so cannot pass the actual value from motion.spindle.speed-out directly

I realised after I had shut the computer down, that in fact the OUT pin is motion.spindle.speed-out, so you can attach 2 IN pins to the linking signal anyway and feed both spindles from it.
No need to unlink and relink at all

net spindle-vel-cmd [second-spindle]-spinout <= motion.spindle-speed-out => hm2_5i25.0.7i77.0.0.spinout

I was thinking of the enable logic to select which spindle is enabled

Yes you are right of course, I was purely thinking of the speed command :whistle:

I would do this with a mux component. (well, actually, two of them acting as a demux)

In fact, the way to do it might be to set things up so that M3 works one spindle and M4 works the other. This will only work if there is no requirement to run the spindles in reverse, or both at the same time if using simple HAL logic to twiddle the connections.

Looking at www.linuxcnc.org/docs/html/remap/structu...p_remappable_codes_a

I think I would be tempted to remap M31, M32, M41, M42 to control the separate spindles.

I don't know if it is possible to require an "S" argument to the M31 command, but it is possible to remap S itself to do something cleverer, such as set the speed of the last-referenced spindle.

Had to take a break awhile with this but now Iḿ on it again.
As I said before, the analog out is not the issue anymore, I got it to do as I like and its not a problem that its on, on both analog outputs at the same time as this is not what starts the spindle.

To add some logic seem to be the best solution and as usual I got stuck on the basic things:

net spindle-cw => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-02
net spindle-ccw => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-03
newsig spindle2enable bit
sets spindle2enable 0
newsig spindle1enable bit
sets spindle1enable 1

loadrt and2 count=2
addf and2.0 servo-thread
addf and2.1 servo-thread
net and1in0 and2.0.in0 <= motion.spindle-forward
net and1in1 and2.0.in1 <= spindle1enable
net spindle-cw <= and2.0.out

This what I got so far but I get the error that spindle1enable does not exist although I can see it in halmeter?

You have defined spindle1enable as a signal, but then later you are trying to use it as a pin.
The format of the "net" command is

net signalname pinname1 pinnname2 … pinnnameN

If signalname doesn't exist then it is created.
pinnames all must already exist. And only one output pin can be connected to any one signalname.
(it is slightly confusing that physical output pins are input pins in HAL, because they accept, rather than output, a value)

I think you code needs to look something like
net spindle-cw => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-02
net spindle-ccw => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-03
loadrt and2 count=2
addf and2.0 servo-thread
addf and2.1 servo-thread

net spindle1enable => and2.0.in0
net spindle2enable => and2.1.in0
net all-spindles-on and2.0.in1 and2.1.in1

net spindle1out and2.0.out => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-02
net spindle2out and2.1.out => hm2_[HOSTMOT2](BOARD).0.7i77.0.0.output-03

sets spindle1enable 1
sets spindle2enable 0

Thanks, now its working as I want it to :)

Here are the final code if someone else want to do the same thing:

#Settings in INI:
[SPINDLE]

MIN_LIMIT = 0.0
MAX_LIMIT = 3000
SCALE_MAX = 3000

[SPINDLE_2]

MIN_LIMIT = 0.0
MAX_LIMIT = 24000
SCALE_MAX = 24000

#HAL:
#Spindle 0-10v
setp hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout4-scalemax [SPINDLE]SCALE_MAX
setp hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout4-minlim [SPINDLE]MIN_LIMIT
setp hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout4-maxlim [SPINDLE]MAX_LIMIT
loadrt abs count=2 #2 behövs endast om 2st spindlar
addf abs.0 servo-thread
net spindle-speed-scale motion.spindle-speed-out => abs.0.in
net positive-only-spindle-speed-cmd abs.0.out => hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout4

setp hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout5-maxlim [SPINDLE_2]MAX_LIMIT
net positive-only-spindle-speed-cmd => hm2_[HOSTMOT2](BOARD).0.7i77.0.1.analogout5

#Dual spindle on/off CW/CCW
#and2.0 = Spindle 1 CW
#and2.1 = Spindle 2 CW
#and2.2 = Spindle 1 CCW
#and2.3 = Spindle 2 CCW

loadrt and2 count=4
addf and2.0 servo-thread

net spindle-cw <= motion.spindle-forward
net spindle-cw => and2.0.in0 and2.1.in0

sets spindle1enable 1
sets spindle2enable 0



#M101 Enable spindel 1
