10:36 AM skunkworks: in halcmd - how can you tell thread order?
10:37 AM skunkworks: *function order
10:38 AM cradek: I bet show thread shows them in order
10:39 AM skunkworks: hmm - could be - but they happen to be in alphabetical...
10:39 AM skunkworks: oops - never mind.
10:39 AM seb_kuzminsky: try removing one of the early ones and adding it back in
10:39 AM skunkworks: I was doing a show funct
10:40 AM skunkworks: not show thread
10:40 AM skunkworks: that makes more sense now
10:40 AM skunkworks: I think the reason why the offset componant isn't working the way I think is because of thread order
10:41 AM skunkworks: in my mind - the offset should happen without motion knowing (pretty simple componant)
10:41 AM skunkworks: I think I have the update-feedback and update-output in the wrong location - causing the issue
11:53 AM jepler: after installing security updates on forum, it requests a reboot. bouncing it now.
01:00 PM seb_kuzminsky: thanks for taking care of the forum...
01:20 PM skunkworks: ah ha! I guess I misunderstood what offset was actually doing. I finally got sim working the way I would like. could not figure out what was limiting the rate change of the offset command. turns out it was the limitation of the max velocity of the software step generator.
01:20 PM skunkworks: lowering the base period - increased the correction speed
01:21 PM skunkworks: now i have to figure out why the pid version of this setup I am playing with has such a slow correction. like <1ipm.
01:22 PM skunkworks: I thought it would be limited by the stepgeneration limits - like the software stepgen but I must have something f-up
01:22 PM skunkworks: the axis is responsive and works correctly - but adding an offset moves the axis at an unbelievably slow correction
02:03 PM skunkworks: I bet it is pid.N.maxerror
02:05 PM skunkworks: hmm - do I feel energetic enough to setup a test config here?
04:36 PM skunkworks: funny how it is obvious now.. Putting a limit3 in front of the step change - fixed all the problems.
04:49 PM seb_kuzminsky: oh that makes sense
04:51 PM skunkworks: chopping it up - allowed me to get the speeds I was expecting
04:51 PM skunkworks: (to the limit of the stepgen)
05:40 PM skunkworks: It is really awesome that I can test real hardware with my laptop.
05:40 PM * skunkworks thinks life is good
05:47 PM skunkworks: http://electronicsam.com/images/matsuura/20171002_171412.jpg
05:49 PM hazzy: Where the sidewalk ends!!! lol
05:49 PM hazzy: Great technical material
05:50 PM skunkworks: isn't it? :)
05:50 PM hazzy: yes :D
05:51 PM hazzy: Every shop/lab should have a copy!
05:51 PM skunkworks: I think I would have to pry it away from the kids
05:52 PM Tom_L: sam, what is that board to the left?
05:52 PM skunkworks: 7i92
05:52 PM Tom_L: mesa obviously... but which one
05:52 PM Tom_L: those are small
05:53 PM Tom_L: 2 25 pin connectors?
05:53 PM skunkworks: and some lambrusco..
05:53 PM Tom_L: db15 & dual row
05:53 PM Tom_L: 25*
05:53 PM Tom_L: heh
05:53 PM skunkworks: yes - 2 'printer ports' worth of i/o
05:54 PM hazzy: My father confiscated "Where the sidewalk ends" when I was little because it is all i read :(
05:54 PM Tom_L: i should try one of those one day but all my daughter cards are 40 pin
05:54 PM Tom_L: does it support sserial too?
05:54 PM Tom_L: i'm sure it does...
05:55 PM cradek: hazzy: my parents recently found my copy and gave it to me
05:56 PM cradek: in the front cover in my kid handwriting it says Birthday 1982 Mom and Dad
07:20 PM skunkworks: wow - 82 - I would have been 9
07:22 PM hazzy: I would have been -11 :D
07:25 PM skunkworks: heh - I am getting old. didn't used to be.
07:26 PM skunkworks: Tom_L, daughter boards that plug in have smart serial options
07:38 PM Roguish: you guys are just kids.....
07:40 PM * hazzy is the little kid
07:43 PM hazzy: Roguish: I just added a categorized widget chooser: https://i.imgur.com/Zt5f2av.png
07:43 PM Roguish: probing is key.
07:47 PM skunkworks: I could not live without my probe
07:48 PM skunkworks: hazzy, liking the looks of hazy
07:49 PM skunkworks: hazzy
07:51 PM skunkworks: I think 'mach' people will like it also
07:54 PM skunkworks: (if you could just get them to try linux...)
07:58 PM hazzy: skunkworks: thanks! I am having too much fun working on hazzy! (to the detriment of my bank account :D )
07:58 PM skunkworks: the homeshopmachinist forum was upgraded last week. - they scrapped it and went back to the old forum. lost a lot of post.
07:59 PM hazzy: Mach people will always be Mach people, I don't know what is it but they always seems very defensive
07:59 PM skunkworks: hazzy, thank you.
08:01 PM skunkworks: there are so many things I want to test... But family, work, and side work takes up too much.
08:02 PM skunkworks: hazzy, a lot of mach people are going to path pilot. if there was a non pathpilot solution that they liked... Linuxcnc is a bit easier to configure.
08:03 PM skunkworks: (Because of tormach)
08:03 PM skunkworks: it is hilarious when they go to path pilot and see how stable it is.. they could have had that 5+ years ago with linuxcnc
08:04 PM skunkworks: it would require wizards though. like native cam or such.
08:08 PM hazzy: I must admit I was a mach person :shudder:, then I started using PathPilot and realized the versatility of LCNC, so I though I would try and make a interface to learn more about the project
08:10 PM hazzy: That was during summer break of 2015. When I graduated last December I took the project back up
08:10 PM skunkworks: again - your conversion is top-notch
08:10 PM skunkworks: well - when you don't know any better. ;)
08:45 PM skunkworks: wow - the last time I got something from emc-users is 7/31..
08:45 PM skunkworks: you would think I would have noticed that.
08:50 PM hazzy: My subscription lapsed about the same time, I never noticed until Andy PMed me to ask if I was still subscribed
08:51 PM hazzy: I was starting to get a little worried about Gene Heskett being so quiet :D
10:03 PM skunkworks: funny - same here.. but he showed up on irc
