Spindle scaling factor

I have now tried the following in my .hal file, but still does not work:
loadrt mux8 count=1
addf mux8.0 servo-thread
net gearbox1 mux8.0.sel0
net gearbox2 mux8.0.sel1
net gearbox3 mux8.0.sel2

setp hm2_5i25.0.7i77.0.1.analogout2-scalemax mux8.0.out

setp mux8.0.in1 400
setp mux8.0.in2 800
setp mux8.0.in4 1600

net gearbox1 hm2_5i25.0.7i77.0.0.input-07-not

net gearbox2 hm2_5i25.0.7i77.0.0.input-14-not

net gearbox3 hm2_5i25.0.7i77.0.0.input-15-not


then I get the following error:

rivol-gun-drill.hal:419: value 'mux8.0.out' invalid for float

please. can someone help me? basically: when pin 07 then output scale must be 400, when pin 14 true, then output scale must be 800, and when pin 1600 is true, then output must be 1600

sorry. here's the files.

I tried analogout 2 = 400 and 400.0
analogout2 is float in, and mux8.0.out is float out

what about

net spindle_scale hm2_5i25.0.7i77.0.1.analogout2-scalemax mux8.0.out

because AFAIK setp only works with numeric constants, not named signals like mux8.0.out

I suspect what the problem might be.

hm2_5i25.0.7i77.0.1.analogout2-scalemax might be a parameter asignment (help me if I'm wrong)
so to setp hm2_5i25.0.7i77.0.1.analogout2-scalemax 400 works fine,
hm2_5i25.0.7i77.0.1.analogout2-scalemax (spindle_9)output-scale works because it is a constant,
hm2_5i25.0.7i77.0.1.analogout2-scalemax mux8.0.out will then not work because it is a float(it can vary while program runs)(help me if I'm wrong)
so: my conclusion: the way that the firmware is done, might not allow this.
but then again, when I look at hal-show, hm2_5i25.0.7i77.0.1.analogout2-scalemax is a float in, and Mux8.0.out is float out. I need to crack this tonight...
Peter: I think you might be able to help with this one?
I tried
net spindle_scale, then it comes with other errors. says pin "hm2_5i25.0.7i77.0.1.analogout2-scalemax" does not exist.

Ahh yes the XXXXX.analogout2-scalemax are parameters, not pins so
cannot be changed dynamically (this is a driver choice, not related to firmware)

So you will probably have to use the scale component in series with the analog_out signal
to accomplish what you want.

Note that the scale component multiplies by the scale value instead of divides so the
mux input constants would be inverse's, for example

setp hm2_5i25.0.7i77.0.1.analogout2-scalemax 1600

setp mux8.0.in1 4
setp mux8.0.in2 2
setp mux8.0.in4 1

net sg scale.0.gain mux8.0.out
...

thank you for everyone's input. muchly appreciated
