[22:44:51] -!- Roguish has joined #linuxcnc-devel
[22:46:35] <Roguish> pcw_home: having serious problems with my setup. the watch_dog is biting me all over. no clue why. had a 5i22, then tried my 5i24. same thing. is this OS related?
[22:47:04] <Roguish> have never had this problem before.
[22:53:14] <pcw_home> WD bite is usually latency related
[22:54:35] <pcw_home> could be hal file related also (wrong WD timeout setting vs servo thread)
[23:07:58] <Roguish> there's a WD timeout setting?
[23:08:35] -!- ve7it has quit [Remote host closed the connection]
[23:09:08] <pcw_home> yes, in the hal file
[23:09:16] -!- ve7it has joined #linuxcnc-devel
[23:10:44] <Roguish> OK, found it. not sure how to set it. it's in the hostmod2 driver section. timeout_ns
[23:21:48] <Roguish> pcw_home: so like this? loadrt hostmod2 timeout_ns=10000000 that's 2x the default of 5000000
[23:24:35] <Roguish> pcw_home: I have SERVO_PERIOD=1000000
[23:27:20] <pcw_home> Yes thats OK
[23:27:35] <pcw_home> what latency do you get on your host?
[23:28:22] <Roguish> not sure right now. haven't checked for a while. it's an asrock q1900m board
[23:28:38] <Roguish> most everything extra turned off in the bios
[23:29:19] <Roguish> running master pre-empt
[23:31:01] <Roguish> i've also been getting spurious other errors like limit switches tripped when nothing is near them. and lots of ferrors, even though i've retuned for the 7i40. a fairly soft tuning. not too aggressive.
[23:33:05] <pcw_home> maybe a noise issue, does the problem go away if motor power is off?
[23:33:30] <Roguish> no idea.
[23:34:15] <Roguish> been running from a launcher. i'll run from a command prompt. can see more errors.
[23:34:32] <pcw_home> If you can try that, it would determine the source of the problem
[23:34:34] <Roguish> are the 7i40's noisy?
[23:36:05] <pcw_home> the probably have faster output switching than the LM18200
[23:36:22] <Roguish> i have pwm_frequency = 40000
[23:36:33] <pcw_home> and much better ground connections to the host
[23:37:05] <pcw_home> so if you have a ground loop of some kind it will cause more issues
[23:37:43] <pcw_home> (better ground connection because all 24 flat cable grounds are used)
[23:37:43] <Roguish> motor power lines are not shielded.
[23:38:46] <pcw_home> you might need to shield them + use a common mode choke (giant ferrite bead) on the motor
[23:38:59] <pcw_home> and perhaps power supply lines
[23:39:01] <Roguish> what do you think the servo period and pwm_freq ought to be
[23:39:43] <pcw_home> servo period maybe 2 KHz PWM 20 to 40 KHz
[23:41:09] <pcw_home> you can get a ground loop if your motor power ground is tied to ground somewhere in the power supply (like a PC power supply)
[23:41:18] <Roguish> 2 KHz == 500,000 ns
[23:41:35] <pcw_home> yes
[23:42:33] <Roguish> I disconnected the PS grounds. I had a wire from the neg term to a common terminal for all the power supplies. I disconnected those.
[23:43:47] <Roguish> Peter you're juggling conversations......
[23:43:53] <pcw_home> Does sound like a ground loop (if the problem goes away with motor power off its a noise issue)
[23:44:39] <pcw_home> I do have some common mode chokes about the size of a walnut
[23:46:22] <Roguish> https://www.amazon.com
[23:49:22] <pcw_home> Yeah those are worth a try (mine are not split so you need the thread the wire through)
[23:50:59] -!- ve7it has quit [Remote host closed the connection]
[23:51:00] <Roguish> thanks. thats' ok. in the middle of machining for an important client. all the problems have cost me way too many hours. i'll get some chokes or find some shielded power cables.
