Perfect, thanks

Yes you can use just one output

Hello all, I am trying to configure `output_sink` and `output_source` pins for my Mesa 7i76eu and I am running into some surprising behavior. My goal is to put `hm2_7i76e.0.7i76.0.0.output-11` into sink mode. 

Long story short, putting `setp hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF` and `setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800` in my HAL file after loading `hm2_eth` does not seem to have any effect, output-11 remains in sourcing mode. I spent some time debugging this and found some surprising results.

The first thing I did was attempt to setup the pins manually without changing anything in my HAL file. For this test, my HAL file did not set `output_sink` or `output_source` at all. On a fresh power cycle of both my computer and the mesa card, the following works correctly (causes output-11 to sink when TRUE).

```
halcmd setp hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF
halcmd setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800
halcmd setp hm2_7i76e.0.7i76.0.0.output-11     TRUE
```

I can toggle output-11 back and forth between TRUE and FALSE and it appears to work just fine. The strange part is that if I set output_source = 0x0000FFFF output_sink   = 0x00000000 (going back to the default value), `output-11` remains in sinking mode, it does not switch back to sourcing mode. The only way I can get it to switch back is if I power cycle the Mesa card.

The second thing I tried was setting `hm2_7i76e.0.7i76.0.0.output_source 0x0000F7FF` and `setp hm2_7i76e.0.7i76.0.0.output_sink   0x00000800` as part of my postgui HAL, the thinking being that maybe there is some timing issue for when you configure the output pin modes. This does seem to work as long as I do a power cycle of the Mesa card and computer, but it feels like a bit of a hack.

I'm using this setup to control activation of a wireless probe receiver which needs `output-11` to sink to ground in order to activate the probe, so my main worry is that I'm just hiding a timing related issue by doing this in postgui and will end up running into a crash down the line. If anyone has some insight into how `output_source` and `output_sink` are supposed to work, that would be appreciated!

Thanks!

Please see attached file

Can i just use one Mesa output for all three driver or do i have to use three outputs? One for each driver. In the LinuxCNC configuration i can set enable for x, y and z axis.

And the PC MUST be set to 10.10.10.nnn where nnn is anything from 1 to 254 but NOT 10.
So yes, the PC set at 10.10.10.11 will work.

Hi all,
I am a newbie to cnc and to linux so please be patient with me. I have seen some posts where using the 7i76eu board can be set to using ip address of 10.10.10.10 I see some guys say changing w2 and w3 manual says w13 and w14 default is 192.168.1.121 with both down. and both up 192.168.1.121+ use fallback configuration. Some guys say w3 and w3 off to set ip to 10.10.10.10. I am confused many say i should be using 10.10.10.10 and hve pc to 10.10.10.11. Does the 7i76eu magically change the ip with w13 and w14 in the default down and the w2 and w3 in down position, or do you have to do something else in progaming also.
This my seem stupid to some of you more experienced users but I am confused!
Thanks for any help

Im Moment ist ENA bei mir auch nicht verdrahtet und die Treiber sind ständig an... mich nervt dieses Motorgefiepe wenn die Maschine nicht aktiv arbeitet. Das ist im Moment noch häufig der Fall, weil ich Einstellungen/GUI/Probe Basic teste. Ein bischen mehr Sicherheit ist ja auch ganz gut.
Danke für deine Antwort

Meine Verdrahtung nun im Anhang

Ich habe die Enable Eingänge an den Motoren einfach frei gelassen die Maschine muss (eh) "festgehalten" werden, wenn der jeweilige Motor sich nicht dreht.

Bei meinem DM860H (noname), geht der Motorstrom aus, wenn ENA+ (5V) und ENA- (GND).
Das funktioniert also prima ohne Enable, ist aber wahrscheinlich so, wie Mücke schreibt.

Moin Mücke,
vielen Dank. Werde ich testen.

Hey, 

ich habe zwar nicht die gleichen Treiber, aber ich habe einfach 5 V draufgegeben und der Treiber war gesperrt. 
Demnach müsste nur ein digitaler Ausgang deiner Mesa-Karte auf ENA+ gelegt werden und der entsprechende GND des digitalen Ports der ESA auf ENA-. 

Wenn der digitale Port dann HIGH ist, müsste der Treiber gesperrt sein.

Errors with limits have nothing to do with what Linux or version of LinuxCNC you are using, the are a setup issue, namely just invert them in hal or in the wizard.

Hi, I am a newbie and I am having the same issue. I tried the bundled package with debian 12 Linuxcnc 2.9.4 iso and installed it. After starting the pncconfig and trying to run the board I got errors with the limit/estop/probe input on TP6. I set those to not used and I could get pulses on the board for movement. If I try to reset those inputs I get the errors again. I am going to try Bendandsends idea of individual install of debian 12.13.0 and Linuxcnc 2.9.8 and see what happens. I do not understand what you mentioned Tommylight when you said already replied to that from Bendandsend. Thanks for all you help I am frustrated now and appreciate all of the help to get this solved

Great and thanks for your quick replay. I´ll check

Does 7i76EU have field power?

hi. after running pncconf wizard, I cannot load linuxcnc because of error below, i was trying to setup sn04-p2 type proximity sensors on tb6 pins 0,1,2 and probe and estop on 4,5. Any ideas to resolve please? (note, im new to mesa and linuxcnc) thanks
