My 7i76e Connection Sheet

Whats wrong with connecting to TB3? Its there for this purpose. I use it.

a year ago  i work on a mile machine  and that time  it work it move  i work with mesa 7i76e.
i have 2 setups   a big one in the workshop (way to cold now) and a smale one (coosie warm) to experimenting  in house   
it stay  there  unused   no time   and now i pick it  up again  
the one in the workshop stil work  
when i take the laptop  in house  i got  an error  when i take the laptop again to the workshop  with the same config work  
what can be the reason  
i got these error message  the last lines  

hm2/hm2_7i76e.0: registered
hm2_eth: hostmot2 ethernet driver unloaded
hm2: unloading
removing hal_lib, rtapi, and real time os modules
removing nml shared memory segment 

debug file information

note: using posix realtime
./sin20220818.hal: pin 'hm2_7i76e.0.7i76.0.0.output-00' does not exist 1552
stopping realtime threads
unloading hal components
note: using posix realtime

someone had an idea  how i can solve thise problem  ?

Typically, that error means that the 7I76E does not have field power

for noise reason i didn't switch it  on and that was critical  thx  it work  now

Hi, I'm having a similar error code when trying to run LinuxCNC

Note: Using POSIX realtime
".custom.hal:81: Pin 'hm2_7i76e.0.7i76.0.0.enc0.count' does not exist"
3999

(The 3999 number changes everytime we try to start up the program)
This only happens when we use a specific code in our custom.hal to control the axis' with a MPG controller.
We've already checked the field power TB1 (pin 5 +24V pin 8 GND) and when we measure P3 there is a 5V available.
The Custom.Hal we used is below.

loadrt mux8 count=1

# For velocity mode, set to 1

These are the loadrt lines that show up in the main Hal file.
We haven't fully configured the spindle encoder yet, because we were trying to figure out how to move the axis' with the MPG, is it possible that the encoder needs to be fully functional before we can use the MPG for the axis'?

Thanks in advance

You would need mode 2 on the 7I76Es I/O section to enable the MPGs:

sserial_port_0=20xxxx

Thanks for the help we got the MPG to fully work after changing the mode to 20 and reconnecting some loose wires.
