7i76e: MPG and Analog inputs with pncconf?

How do you connect that code to halui?
Can you make a HAL pin in the .axisrc file?

Chris M

Yes, you can create a component and connect it in .axisrc

Cheers, Phill

I have modified the hal file to usw ilopass for the mpgs:

this is working, but only for "jogincr.in00" the other increments 01,02 do not work anymore.
these worked before i added the ilowpass.

what is going wrong with my new hal?

You might need to make all the jogincr numbers (in the mux16) 100x smaller to compensate for the 100x scaling of ilowpass.

i edited the second newest hal file, not the last one. this was my problem, now it is working.
@andypugh: i made the jogincr numbers smaler.

the maschine gos very smooth now with the mpgs!

## The above line is to be able to jog without homing ##

i added these two lines for x and z axis (joint 0 and 1). but i'm still not able to move the machine until it is homed.
Where can I find documentation on the subject?

Do you have this in the [TRAJ] section of the INI?

NO_FORCE_HOMING = 1

Yes i've this in my ini:
"[TRAJ]
COORDINATES = XZ
LINEAR_UNITS = mm
ANGULAR_UNITS = degree
DEFAULT_LINEAR_VELOCITY = 2.50
MAX_LINEAR_VELOCITY = 25.00
POSITION_FILE = position.txt
NO_FORCE_HOMING = 1"

Hi

I'm just trying to import some analog value from MESA 7i76e into LinuxCNC.
I thought the input was working on 4..20 mA signal, but I probably is detecting only the voltage source

Somebody can tell me the range ? I guess 0 to 24 Volt , what I'm actually using now...

However I'm trying to get the corresponding value from the HAL meter, but probably I'm not reading the right signal...

From the HAL-meter , Parameter Tab, I look at
hm2_7i76e.0.7i76.0.0.analogin0

but I get simply a fix value, even if I change the voltage from 0 to 20 VDC

Some inputs ?

From the 7i76 manual

ANALOG INPUTS
All field input pins are capable of reading the input voltage. These are not highly
accurate or high resolution but can be useful for things like potentiometer inputs. Input
resolution is 8 bits and input full scale value is 36.3V. Accuracy is +-5%. Software process
data modes 1 and 2 allow reading the analog voltage on inputs 0 through 3, in addition to
the 32 digital bit inputs

Have you set the smart-serial software mode correctly? (loadrt hm2_hm2_eth .... sserial_port_1="200xxxxx" or similar?
(I think you probably have, as I don't think that the pins will appear in HAL otherwise)

Is the hm2_7i76e.0.read function definitely running?

(halcmd show thread will show this, the exec time number should be different every time you call it)
