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

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

Hi, I'm having a similar error code when trying to run LinuxCNC
Note: Using POSIX realtime

(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.

In the main hal file, the loadrt line, does it set the board to mode 1 or mode 2?
Same line, does it have number of encoders at anything but 0?
Normally encoder 0 would be the spindle encoder, are you using that for MPG?

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

loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS

loadrt hm2_eth board_ip="192.168.1.121" config="num_encoders=1 num_pwmgens=0 num_stepgens=5 sserial_port_0=00xxxx"
setp hm2_7i76e.0.watchdog.timeout_ns 5000000

You would need mode 2 on the 7I76Es I/O section to enable the MPGs:
sserial_port_0=20xxxx
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.
