loading LinuxCNC on old smithy 1240

Its clear that the correct firmware was found most times LinuxCNC was launched
It really seems like some more basic issue.

Can you run a latency test?

The problem seems to be with loading motmod. What is your actual "loadrt [EMCMOT]...." line now?

this is what we had changed it to
loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD traj_period_nsec=[EMCMOT]TRAJ_PERIOD  num_joints=[KINS]JOINTS

and from ini file

[EMCMOT]
EMCMOT = motmod
SHMEM_KEY = 111
COMM_TIMEOUT = 1.0
BASE_PERIOD = 250000
SERVO_PERIOD = 1000000
TRAJ_PERIOD = 1000000



 

I changed the loadrt [EMCMOT] line back to what it was
loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD traj_period_nsec=[EMCMOT]TRAJ_PERIOD key=[EMCMOT]SHMEM_KEY num_joints=[KINS]JOINTS

and the gui comes back up, but it is full of "red Lights" although the start button now works it won't let the home button become active.
I'll attach a pic

 

Has a line-break been introduced by accident into that line?

What are the "red lights" ?

I don't believe there was a line break inserted. Attaching pic again, hopefully it works this time

Does it come out of e-stop?

The 8i20 side panel is all red because the 8i20 HAL (postgui hal) was disabled. You can try uncommenting that.

yes, it came out of estop. I'll look for postgui hal.
are you on chat tonite?

I enabled that line, it came up with 2 green lites this time, but when I tried it again to make note of them, it won't start gui again

OK, so enabling the original line
loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD traj_period_nsec=[EMCMOT]TRAJ_PERIOD key=[EMCMOT]SHMEM_KEY num_joints=[KINS]JOINTS
gui comes up and 2 lites are now green "C" and spindle at speed
