MESA 7i76EU - Pinzuordnung (z.B. Endschalter)

Category: Deutsch

Hallo Raspll,
danke für deinen Post! Jetzt wird mir einiges klarer.
Ich arbeite mich gerade durch das Handbuch um HAL und INI händisch anzupassen.
Genau aus dem von dir beschriebenen Grund.

But If I don't select "7i76 Modus 2 I/O card" my settings are lost after closing and reloading Pncconf. 
Do I have to select Modus 2 anyway even If I change locale to UTF-8 EN_US ?

ok, after searching for the missing tab i found this post  
After enabling the option „Show advanced config pages“ I could modify the value "0: 7i76 Modus I/O Kart..". After modification the tab 7i76 I/O (SS#0) is available, now.

Use the LinuxCNC ISO written to USB to boot the PC in English language, start PncConf to make the config, save it on the hard drive or another USB.
Or change locale to UTF-8 EN_US

You should get a screen like this:

 

If not. it may be that you have hit a locale bug in pncconf and may have to
temporarily set the locale language to  en_US to work around the issue.

MESA 7i76EU - Pinzuordnung (z.B. Endschalter)

Category: Deutsch

Hallo,
ich bin gerade am Umbau einer ISEL CPM3020 von IMC4 auf MESA 7i76EU. Die Kommunikation von LinuxCNC zur Karte funktioniert.
Aktuell hänge ich an der Konfiguration der Referenz- und Endschalter fest. Ich versuche via Pncconf die Pins festzulegen, finde aber im Menu "Mesa Karte 0" nur Zuordungen für TB2/TB3, P1 und P2. Bei P1/P2 könnte ich die Schalter zwar anlegen, dann bekomme ich aber Pin Nummern die m.E. mit den Field I/Os nichts zu tun haben sondern nur mit den I/O Expansion connectoren. Ich habe trotzdem mal darüber die Schalter konfiguriert, das Ergebnis sieht in der HAL Datei dann wie folgt aus (Leerzeilen entfernt):# externe Signaleingänge
# --- MIN-HOME-X ---
net min-home-x     <=  hm2_7i76e.0.gpio.017.in
# --- MAX-X ---
net max-x     <=  hm2_7i76e.0.gpio.018.in
# --- MIN-HOME-Y ---
net min-home-y     <=  hm2_7i76e.0.gpio.019.in
# --- MAX-Y ---
net max-y     <=  hm2_7i76e.0.gpio.020.in
# --- MIN-Z ---
net min-z     <=  hm2_7i76e.0.gpio.021.in
# --- MAX-HOME-Z ---
net max-home-z     <=  hm2_7i76e.0.gpio.022.in


Eine Konfigurationsseite für TB5 oder TB6 zur Konfiguration der Field I/Os kann ich nicht finden. Wo ist mein Denkfehler?

I have had loong time before network tunning done this ... it is basic stuff for latency reduction at any hardware

I will do the kill of EEE and I will share the resaults in comming weeks .. thanks for hint !

Mesa Configuration Tool

I did not get a working stepper configuration out of MesaCT with a 7i76eu. I have posted the output and my working config here forum.linuxcnc.org/configuration-tools/5...erated-configuration

The output was supposed to be on the 02 stepper but it was connected to the 00 stepper. The feedback loop was not closed and it was not set to be in velocity mode. Look at the two configurations.

7i76eud.bin firmware did the trick. Interesting this firmware does not show up in the MesaCT list when using the Configuration Tool. It was in the /lib/firmware/hm2/ folder but it was not showing up in the drop down list.

MesaCT and 7i76eu Issues with generated configuration

Category: Configuration Tools

It could be that I am an imbecile. However when I used MesaCT as installed per the instructions here using apt gnipsel.com/linuxcnc/mesact/install.html#install-with-apt. I did not get an anywhere near working configuration out of the tool. The stepper configurations were very incomplete. The feedback loop was not closed in fact the PID output was not even sent to the mesa stepper driver. 

I will post up my configuration files from the output shortly.

If you don't have an added parallel daughtercard, you should normally not change the
installed firmware.

The default 7I76EU firmware is 7i76eud.bin, to re-install:

mesaflash --device 7i76eu --addr [card_ip_address] --write 7i76eud.bin --reload

where [card_ip_address]  is either 192.168.1.121 or 10.10.10.10 depending on how you
have the card setup.
