Had the same issue, need to wire the "orange block" so that your inputs and outputs have power. You should see a yellow light only with only Ethernet or 5v power..... and a red or green light with field power.

I think it's just the bottom one on that orange block that needs 24v and the top one needs ground but that's from memory.... please check the manual

Hello,

I am using Mesa 7i76eu card to operate my 3 axis CNC mill. I connected the stepper motors and they work, I can move them with linuxCNC. Now I tried to connect PNP proximity sensors to use as homing switches, but they are not working. At first I was also getting an error when starting linuxCNC, but i noticed that is because W1 jumper fell out while wiring. I set the W1 jumper back to its original left position but the pins are still not working. I also noticed that i have a CR11 LED light turned on indicating field i/o fault. Does anyone have an idea what could be the problem.

Success!
I moved that line to my posthui.hal and now everything works.

Thx for the support. 

Its not easy to add a 3rd MPG to a 7I76E/7I76EU isolated I/O
But it would be easy to add 3 or 4 to the parallel expansion port
of a 7I76E,7I76EU,7I96,7I96S,7I95,7I95T etc as long as the MPG
just has 5V signals

Another easy way to add 4 MPG inputs to almost any card and simplify cabling
is to add a 7I73

 

I have never run this sort of mill- it originally had 3 handwheels, one for each axis, i dont know the resolution of them, but i doubt they were 100ppr, im thinking more like 200-500 to do half thou or 2 tenth motion(assuming 1 rotation was .1"), at least thats what would make sense for me.

i have another question: can a 3rd mpg encoder be added to the firmware of a 7i76e?

Also thanks a lot for the help, and this forum. amazing place!

Update / Wednesday 5:52PM: 
finally found the root cause for this behavior.
Its line 25 in my pendant.hal

# --- ESTOP-EXT ---
net pendant-estop     <=  hm2_7i76e.0.7i76.0.0.input-29

when I comment it out, everything is fine. 

Now I just have to understand whats going on with this signal.

Regards
Sebastian

OK, I am one step closer.. I created a "virgin" configuration.. that worked fine and didnt show this error. Than I started copying my old config file by file into the new folder to narrow down when this error would be introduced.

And - believe it or not - it happens as soon as I include my pendant.hal file.

Here is a screencast. Its 100% reproducable.


As soon as "G54" is highlighted in the top left corner, everything is fine. When its "off", I always get this popup...

Does this make any sense to you?
this is my config.

Thanks for the tips! 

I applied it to my setup and realized that the net pdnt.spindle.is-on whb.halui.spindle.is-on spindle.0.on"
"net pdnt.spindle.is-on => hm2_7i76e.0.7i76.0.0.output-11" 

In my Hal file. Everything is working now. Thanks!

Pretty sure this is all you need
net spindle.0.on hm2_7i76e.0.7i76.0.0.output-11
or this
net solenoid-bearing_air spindle.0.on hm2_7i76e.0.7i76.0.0.output-11

Ah, even easier. Thanks!

Like so ( I would also like to use manually using code, thus mapped to motion pin)?
net solenoid-bearing_air spindle.0.on hm2_7i76e.0.7i76.0.0.output-11 <= motion.digital-out-05

Hello everyone 
I want to create a new screen for a machine that i am working on 
Qtdragon seems ideal for me but i need to modify it by deleting some sections that i don't need and adding other sections and buttons i already installed glade and also qt creator. 
The board that am using ( mesa 7i76e) is in the machine and it's a bit far from me i couldn't use it for now so i can't create a project using my board configuration 
So i need to create a modified qtdragon template or modifying the .ui file of the qtdragon template 
When i create sim project based on qtdragon i couldn't find where i should make the modifications (.ui file doesn't exist in my project directory)
Anyone has an idea how to do that ? 
Thanks in advance

thanks for the hint with the wiki! -). I just added this under "Misc stuff".

Thanks.

I soldered both resistors in the + und - Line inside the plasma source and also connected the 2 torch-start pins of the plasma-source with the Spindle enable + and Spindle enable - -Pin of the Mesa 7i76e-board.

When I power up the plasmacutter it instantly fires although the torch is not activated in plasmac. When I remove the 2 wires from spindle enable +- then the plasmacutter doesn't start when powered up.

When I measure between s-en+ and e-en- with a multimeter there is no connection but the plasma fires when started. Maybe somebody has an idea ? Do I need an additional relays ? With the hypertherm powermax 1000 G3 on the same mesa-card this didn't happen ?

Maybe sb has an Idea?

Okay so I ordered a 7i76eu board a 10.9 touch screen a vandal resistant keyboard and mouse and a little fan less pc. 5v powersupply and a 24v powersupply. A incremental ebay linear encoder. I also programmed a little python program that will act as a gui.  

You could consider adding this to the Wiki too.
