I'm sure you can and it works. My point that I was trying to make is, as an example say, your pot is set at 50% and you move your slider in the gui to 100% the pot is still at 50% in it's physical position and not at 100%. They will be mismatched.

Hi OT-CNC
I can see in gmoccapy all trhre values I set via pots in realtime.

Nop
If I draw my pot-button the view in gmoccappy changes and also slider plus digital value changes according pot position.

Hi All,
So i am was trying to copy - paste the feed override script to my other machine that uses the same board.
Only thing is i got this error says scale already exist.
Also, i see in hall show that the analog input is called input-00 instead of analogin0.
this pin is also not float value.
mean while i am also setting up a mpg with 2 switches for counts and X and Z.
not working either.
mpg is based on this. changed the inputs for my mesa 7i76e
mpg example
base-thread also does not exist ...
any one got a clue?

7I76E analog inputs have these names:
hm2_7i76e.0.7i76.0.0.analogin0
hm2_7i76e.0.7i76.0.0.analogin1
hm2_7i76e.0.7i76.0.0.analogin2
hm2_7i76e.0.7i76.0.0.analogin3
You will need to include "sserial_port_0=20xxxxxx" in the config=" blah blah blah"
section of the hal file to enable the analog inputs (and the MPG encoder inputs)
The MPG example you show is for a parallel port, when using the 7I76E MPG inputs
you do not used the encoder component or the base thread, but rather use the MPG
encoder counts directly from the 7I76E:
hm2_7i76e.0.7i76.0.0.enc0.count
(first MPG counter)
hm2_7i76e.0.7i76.0.0.enc1.count
(second MPG counter)
hm2_7i76e.0.7i76.0.0.analogin0
hm2_7i76e.0.7i76.0.0.analogin1
hm2_7i76e.0.7i76.0.0.analogin2

thanks for the reply.
offcourse.....the serial, forgot about that. i changed it.
for now i removed the mpg stuff to get the feedrate knob to work first.
i get a weird debug, still the same.

okay this is weird,
i tried to build it up without the scale to find if its working.
this does not exist...

Looks like you are trying to "loadrt scale" twice.
That will not work, if you need more scale components, you need to
specify how many to instantiate (either by number or by multiple names)
in a single loadrt line
man scale

thats what i thought. thats clears it up more.
do you got a example how it should look like for a second scale line?

got it!!
in main hal file i got
and in my postgui_call_list.hal
gmoccapy.analog-enable does not exist, but instead it is gmoccapy.feed-override.analog-enable
in main hal file i got
loadrt scale names=scale.spindle,scale.feed
addf scale.feed servo-thread
and in my postgui_call_list.hal
setp scale.feed.gain 0.0417
net feed-override-raw hm2_7i76e.0.7i76.0.0.analogin0 => scale.feed.in
net feed-override-scaled scale.feed.out => gmoccapy.feed-override.direct-value
setp gmoccapy.feed-override.analog-enable 1gmoccapy.analog-enable does not exist, but instead it is gmoccapy.feed-override.analog-enable

Hi,
How would i need to modify the above HAL lines to get it to work in QTPyvcp ? I'm using the QTdragon GUI. I have connected a 10k pot to Analog0 on a MESA7i76E. Mode =1.
Do I just takeout the gmoccapy ? I want to use the pot to control feedrate .
Thanks.
