[05:41:28] <pink_vampire> hi
[05:42:08] <pink_vampire> i have a question for the developers
[05:42:59] <pink_vampire> Is there a way to send a signal to pin9 in the lpt each time that any of the the axis move?
[05:44:43] <pink_vampire> any of the the drivers get pulses, I need to get 1 logic in pin 9, when non of the drivers get pulses pin 9 go to 0 logic.
[05:45:10] <pink_vampire> Something like that can be done with linux cnc??

[06:31:25] <seb_kuzminsky> pink_vampire: there's probably a couple of ways to do that
[06:32:00] <seb_kuzminsky> if you're using steppers with software step generation you could OR all the step outputs together and send the result to pin 9
[06:34:25] <pink_vampire> seb_kuzminsky: I need it and "move/dont move" (like on off)

[12:18:30] <jthornton> linuxmint 17.3 with rtai
[12:21:22] <skunkworks> I would guess your missing the correct apt source. I am assumming there isn't one for linuxmint
[12:21:48] <skunkworks> you would grab the deb from linuxcnc.org.. I don't know where it is yet..
[12:21:56] <jthornton> I have it somehow on two other mint pcs
[12:22:17] <jthornton> just found this googling deb
http://linuxcnc.org wheezy base
[12:36:50] <skunkworks> jepler, this morning I got this
[12:36:51] <skunkworks> http://pastebin.com/1rWahXph
[12:37:06] <skunkworks> (the following errors is me trying to run a program)
[12:38:11] <jepler> hm2/hm2_7i92.0: error finishing read! iter=148384927)
[12:38:42] <jepler> I wonder why that got printed twice
[12:38:50] <jepler> I wonder why nobody has fixed that stray ")"
[12:39:19] <jepler> anyway, before the branch that's what you'd get with a single failed read. once in this state, there's a HAL pin you have to reset to resume trying to communicate.
[12:39:34] <skunkworks> ok
[12:39:45] <jepler> so after this has happened, the following error is not unexpected -- the motors shouldn't actually be turning
[12:39:55] <jepler> this is pin hm2_7i92.io_error or something like that
[12:40:30] <jepler> anyway, with my branch this should only occur after a "large number" of errors communicating with the board in a cluster
[12:41:37] <jepler> .. but I assume yo've run this setup for much more than 140 million base periods (1.7 days at 1ms) in which case it's a surprising result
[12:42:52] <skunkworks> I know it has run for a week..
[12:43:33] <skunkworks> no realtime error.
[12:43:46] <skunkworks> which is what I would have expected.
[12:44:54] <skunkworks> heh
[12:44:57] <skunkworks> So many matsuuras out there with arcane yasnac controls. Like it.
[12:44:57] <skunkworks> When is your conversion kit going on the market ?
[12:53:04] <skunkworks> pcw_home, could the ethernet boards run poe? ;)
[13:01:54] <jepler> my branch lowers the maximum time it will wait for a packet to get back from "way enough to cause a realtime error while waiting" to 60% of the servo-thread period
[13:02:14] <jepler> but even if there's an occasional packet that takes between 60% and 100% of servo-thread period to get returned, you wouldn't expect a cluster of them
[13:24:25] <skunkworks> The servo thread tmax is 794us
[13:24:44] <skunkworks> if there was a bunch in a row at that delay?

[14:05:48] -!- skunkworks_ has quit [Read error: Connection reset by peer]
[14:29:10] <pcw_home> skunkworks: on hm2_eth before jeplers patch, a "error finishing read" really means a lost packet (I think it waits 200 ms or something like that)
[14:30:06] <pcw_home> by which time of course everything's bolluxed up
[14:35:05] <pcw_home> I have a test setup with the read timeout threshold set so theres a timeout 100s of times a day and its been fine
[14:35:07] <pcw_home> (still doesn't work with sserial however)
[14:37:00] <pcw_home> is it possible the 7I92 lost power?
[14:38:38] <pcw_home> I should probably put a "cold start cookie" somewhere so this can be checked
[14:39:06] -!- racicot has quit [Changing host]
[15:02:01] <skunkworks> hmm - I don't know - it is running off a wall wart..
[15:02:05] <skunkworks> I could try a different one
[15:02:20] <skunkworks> or - now I could use usb. let me try that.

[15:55:14] <jepler> I should also try leaving mine running for a few hundred hours
[15:56:11] <jepler> I am dreading trying to figure out how to deal with lost packets when it comes to the serial devices.
[15:58:02] <pcw_home> I think the easiest thing (for almost all modules) is to not process the rx data (or use the stale data)
[16:02:30] <pcw_home> (when a packet is lost, or times out)
[16:04:03] -!- Komzpa has quit [Ping timeout: 240 seconds]
[16:10:10] <pcw_home> I think the problem sserial is that the RX data is all Zeros if timed-out which causes havoc in the control register data parsing
[16:15:55] <jepler> I still have the sserial boards so I can test this
