something else is happening.
I have in my .hal file (changing the analog pins):

loadusr -Wn Therm 
/home/linuxcnc/linuxcnc/configs/ARM/BeagleBone/BeBoPr-Bridge/ReadTemp.py 
-n Therm --num_chan 2 -t 1 1 -a 5 6

further:
# PID for Extruder 0 temperature control
net e0.temp.meas    <= Therm.temp0

and:
# PID for Bed temperature control
net bed.temp.meas    <= Therm.temp1

now when I slide the POT meter, both the temperature bar as well as the 
bed temperature bar in Axix rise, although not the same values......
