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. 

Gruß Mücke

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

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

Debug file information:
Note: Using POSIX realtime
./3020f.hal:31: Pin 'hm2_7i76e.0.7i76.0.0.input-00' does not exist

Yes, the PNP connection is correct for a 7I76E field output (With appropriate series resistor)

Note the the default operational mode for Step drive enable inputs is disabled when powered
(which is the exact opposite of the desired operation from a safety standpoint)

Unless you can reverse this (so they are enabled when the enable input is powered)
You may need to add an external relay.

Hi,
I would like to connect the ena+ and ena- inputs of my Leadshine DM856 to a Mesa 7i76e. If you look at the attachments... which circuit should I use? I would say PNP... but is that correct?

Moin,
ich würde gerne die ena+ und ena- Eingänge meiner Leadshine DM856 bei einer Mesa 7i76e beschalten. Wenn ihr euch die Anhänge anseht... nach welcher Schaltung muss das geschehen? Spontan würde ich nach PNP sagen... nur ist das richtig?

You are trying to control a hal pin, so you will want to use a HalButton from the custom widgets tree. the halpin will have the pinBaseName property you need to set for the button's connection to your licht net. see image below for references:

 



the button color can be style in the stylesheet (see image below) using the following color connections:
Code:
.HalButton { background: qlineargradient(spread:pad, x1:0, y1:0, x2:0, y2:1, stop:0 rgba(226, 64, 64, 255), stop:0.446154 rgba(204, 0, 0, 255), stop:0.764103 rgba(225, 67, 67, 255), stop:1 rgba(249, 142, 142, 255)); } .HalButton:checked { background: qlineargradient(spread:pad, x1:0, y1:0, x2:0, y2:1, stop:0 rgba(154, 231, 153, 255), stop:0.0974359 rgba(92, 243, 81, 255), stop:0.446154 rgba(52, 251, 35, 255), stop:1 rgba(154, 231, 153, 255)); }

 



The button probe_basic_postgui.hal file connection code is as follows:
Code:
loadrt time loadrt not addf time.0 servo-thread addf not.0 servo-thread # *** Time items required for Probe Basic to run *** net prog-running not.0.in <= halui.program.is-idle net prog-paused halui.program.is-paused => time.0.pause net cycle-timer time.0.start <= not.0.out net cycle-seconds qtpyvcp.timerseconds.in <= time.0.seconds net cycle-minutes qtpyvcp.timerminutes.in <= time.0.minutes net cycle-hours qtpyvcp.timerhours.in <= time.0.hours #  ---manual tool change signals--- net tool-change-request     =>  qtpyvcp_manualtoolchange.change net tool-change-confirmed   <=  qtpyvcp_manualtoolchange.changed net tool-number             =>  qtpyvcp_manualtoolchange.number # *** Probe graphic simulation trigger push probe tip *** net probe-in  =>  qtpyvcp.probe-in.out net probe-in  <=  qtpyvcp.probe-led.on # *** Set line below for actual spindle readout from your hal file *** net spindle-rpm-filtered scale_to_rpm.out  =>  qtpyvcp.spindle-encoder-rpm.in # *** custom gui hal widget connections *** net licht  <=  qtpyvcp.licht-button.checked net licht  =>  hm2_7i76e.0.7i76.0.0.output-02

once done you should have something that works like this gif below, but for your physical light:

After some days of trial and error i don´t know further

I created a button "Licht" in QtPyVCP. This light button should switch on my hm2_7i76e.0.7i76.0.0.output-02 from my Mesa 7i76e. In my probe_basic_postgui.hal and tried to implement this function with no success. See postgui Liine 28 and 29.

In addition it would be nice when the "Licht" button is read when off and turns into green when on. The Power on button in the basic GUI turns into green when on.
 

Code:
[code]Debug file information: .... /home/cnc/linuxcnc/configs/Fräse_Probe/probe_basic_postgui.hal:28: Pin 'qtpyvcp.licht.out' does not exist Failed to load POSTGUI_HALFILE with error: 1 .... [code]

I have it working now. I had my serial cable wired wrong. (I had the polarity of the RX and TX wires wrong.)

It's supposed to be a 7i85 not a 7i85s. I'll have to check it in the morning.
I'll also have to check the piece of patch cable I used. It's possible the cable could be suspect.

Yes, it may be a cable issue.

Just verified that:

7i76eu_7i76x1_7i85x1d.bin from the distribution zip file.

md5 checksum:

485114d3d22390a7e5b44d77588981c5  7i76eu_7i76x1_7i85x1d.bin

Works correctly with a 7I85 on P1 (all 5 sserial ports on the 7I85 work correctly)

Is it possible you have a 7I85S rather than 7I85?

Yes, it was sleeping for days before it received the kiss of life!
