Yeah if Milton came ashore as a cat5 I am pretty sure it would be quite a while before you all would've been hearing
from me. I am just dumb struck at the mess Helene had become and still is.

Great to know you survived. In the end, as far as hurricanes go, Milton's Category 3 was a bit of a Fizzer. Shame about the storm surges and flooding though!

it is called Analog servo interface , this card will explain

If you are not already using ClassicLadder, and don't want to bother adding it, it can all be done in hal as well.

I think I'd attack this something like this.

loadrt and2 count=2
loadrt xor2 count=1
loadrt siggen num_chan=1
addf and2.0 servo-thread
addf and2.1 servo-thread
addf xor2.0 servo-thread
addf siggen.0.update servo-thread

setp siggen.0.frequency 2

#Yellow Light
net yellow-in1 <= halui.machine.is-on => and2.0.in0
net yellow-in2 <= halui.program.is-idle => and2.0.in1
net yellow-out <= and2.0.out
net yellow-out => hm2_7i76e.0.7i76.0.0.output-01 #(or what ever your output pin is for the yellow light)

#Green Light
net green-in1 <= halui.program.is-running => xor2.0.in0
net green-in2 <= halui.program.is-paused => and2.1.in1
net flash <= siggen.0.clock => and2.1.in0
net green-flash <= and2.1.out => xor2.0.in1
net green-on <= xor2.0.out => hm2_7i76e.0.7i76.0.0.output-02

#Red Light
net red-on <= halui.estop.is-activated => hm2_7i76e.0.7i76.0.0.output-00 #(or what ever your output pin is for the red light)


(I just have a big red light on each of our machines that turns on when they are not running a program.)
 

 

I have a question which may be version related.  This line:
net yellow-in1 <= halui.machine.is-on => and2.0.in0
gives me the error:
/usr/share/linuxcnc/hallib/qtplasmac_comp.hal:21: Pin 'halui.machine.is-on' was already linked to signal 'yellow-in1'
when I try to run this in version 2.9.3

Could anyone give me some insight into why, and maybe a way to make it work?  I am a total newbie at HAL coding.

I found the error!

After two days of checking, measuring with the oscilloscope, calculating number of pulses by measuring the frequency and pulse duration,  I was questioning my sanity.
I also throughly tested the other axis which are fine, so I compared the axis in all the files and found my error.which should have been set to
I changed the value and had to invert the axis. Everything is running smoothly now.

you need to net the pins with a name, so something like:

hello guys

Today I had a problem, suddenly my computer didn't read the ethernet port and I didn't see any lights on the ethernet port on my computer.
so I conclude, my ethernet port is damaged.

the light on the mesa 7i76e's ethernet port is running. and I tried ping 10.10.10.10 from my LAPTOP and as a result, it worked. Mesa 7i76e is not damaged.

So my suspicions about the Ethernet port on my computer are even more certain.


My question is, can I use a USB to Ethernet adapter on my computer to run LinuxCNC?

Is it reliable? or is it a no no?

Thanks in advance for any help

7i76e_7i76x1_Dpl.bit is the firmware needed for a 7I76E and multiple THCADs

The load resistor for Ohmic sensing determines the sense current
I would not use higher than 25K

Note the if you use a lower value you need to make sure that you do not exceed
the resistors power rating with the open circuit plasma voltage.

Next I want to add ohmic sensing. With a Thad. 

I have downloaded the Firmware files from mesa. There are many files in the hostmot2 folder but have no idea which file I need to flash unto the 7i76E mesa board. What is the file name?

other question is about the serial resistor between positive and Thcad recommended is 390k but in one of the threads 25k is recommended can I freely experiment with resistors? Or does it need a high value to protect the Thcad?

It may be fixable but hard to say without further testing

Hello All,

i hope that my question is in the correct corner.
I want to play with home made Component for my hal Files. I have seen en read lots of it. but in te terminal command i can not locate for example the and2.ko file. i can  see the  and.so file. but that is a compiled file i read.

i have the standard debian 12 preemptrt iso installation withe e MESA 7i76E card

i have also update my system to the latest version.  do i have to instal somthing more ?
do someone 1 suggestion.

 

had a home switch come loose and short something now i have a power fail on my 7i76e, think this can be repaired or am i looking at a new board?
 

tied the 24 volt and 5 volt commons together all is well.

Thanks for the help.

jim

no.
