[15:12:02] <micges> cradek: can you shortly describe on what are you working at locking-rotary branch?
[15:12:26] <cradek> it is done except for homing
[15:12:44] <cradek> it is for machines that need to unlock or lift the rotary axis before moving it, then lock it again afterward
[15:13:10] <cradek> a rotary axis of this kind is used for indexing only, not coordinated motion, so it can only be moved alone
[15:14:10] <cradek> there is a hal loopback for the axis, axis.N.unlock -> axis.N.is-unlocked
[15:14:30] <micges> cool
[15:14:52] <micges> I think I have already machine for tests :)
[15:15:10] <cradek> the only reason I haven't merged is because homing should know to unlock, then home the joint, then lock
[15:15:24] <cradek> I did the work already of passing the option into homing
[15:15:33] <cradek> all that it needs is two more states in the homing state machine
[15:15:51] <cradek> neat - you also have some machines that need this?
[15:16:11] <micges> probably yes
[15:16:33] <micges> I have 5 axis machine with rotary moved by hand and locked by hand
[15:17:10] <cradek> interesting
[15:17:36] <cradek> if I remember right, skunkworks's machine will also need this for the B axis
[15:18:09] <micges> soemthing like this machine: http://www.youtube.com/watch?v=Z7hJr64VF30
[15:18:17] <cradek> I would be happy if you wanted to fix up the homing state machine and then we could merge this
[15:18:26] <cradek> ok I will look later - no flash here
[15:18:41] <micges> ok
[15:19:02] <cradek> bbl
[15:19:13] <micges> bbl
[16:01:49] <skunkworks> * skunkworks raises his hand
[16:02:00] <skunkworks> that is awesome!
[16:03:03] <skunkworks> for my b axis to rotate - it actually lifts the table.
[16:09:33] <micges> skunkworks: got any pics of your machine?
[16:23:09] <skunkworks> micges: http://www.electronicsam.com/images/KandT/oldkandt.JPG
[16:24:47] <micges> skunkworks: when did you take this photo? ;)
[16:25:50] <skunkworks> heh - that is the photo from the manual ;)
[16:25:58] <skunkworks> 69ish maybe
[16:26:20] <skunkworks> http://www.electronicsam.com/images/KandT/DSCCurrent.JPG
[16:27:15] <micges> cool: simmilar to my
[16:27:18] <micges> machine
[16:29:00] <skunkworks> do you have pictures?
[16:30:03] <micges> not yet
[16:30:18] <skunkworks> you need to work on that. ;)
[16:31:08] <micges> heh
[16:32:40] <cradek> skunkworks: are you going to get rid of the entire old control box?
[16:35:13] <skunkworks> already gone.
[16:35:33] <skunkworks> we have two of the electrical panals that we are going to use for electronics.
[16:36:13] <skunkworks> 2 of these.
[16:36:15] <skunkworks> http://www.electronicsam.com/images/KandT/conversion/mainelectricalbox.JPG
[16:36:29] <cradek> nice size
[16:37:24] <cradek> looks like you could put a handy knee mill or something in place of the old control box
[16:37:58] <skunkworks> ?
[16:38:29] <cradek> am I seeing it wrong - the old control looks as big as the machine
[16:38:54] <skunkworks> oh - right.
[16:39:00] <skunkworks> yes - it was huge.
[16:39:17] <skunkworks> it will probably be where tools and maybe a desk ;)
[16:39:18] <cradek> I meant are you able to get rid of the whole control box and use those little ones instead?
[16:39:26] <skunkworks> yes
[16:39:29] <cradek> heh, nice
[16:39:46] <cradek> how long until an axis moves?
[16:40:14] <skunkworks> we have all the pullys now - soon I hope.
[16:40:36] <skunkworks> getting wiring figured out - lots of wires ;)
[16:41:08] <cradek> have you figured out whether you can get a usable signal out of the accupins?
[16:41:39] <cradek> I bet Jon E's board isn't strong enough to drive them - but maybe he could make you something.
[16:43:13] <skunkworks> we are planning on sending a set of accupins and head to him - he thought he could maybe boost the power if needed
[16:43:22] <cradek> neat
[16:43:36] <skunkworks> it would be cool to get that working again.
[16:43:37] <cradek> hm, I've got a crazyass resolver I've been meaning to send him too
[16:44:48] <cradek> yeah it would be really slick to have another dual feedback machine - our first try sure seemed to work great
[16:45:29] <cradek> maybe others are doing it, but I don't know about it if so
[16:49:22] <skunkworks> heh
[16:49:30] <skunkworks> yes - it will be neat.
[16:49:59] <skunkworks> I thing the way the inputs/outputs are adding up - we are probably going to use 2 mesa cards. (2 servo interface cards also)
[16:50:37] <cradek> yeah I even used two on jr - I/O gets used up fast on a complex machine
[16:51:39] <cradek> I'm happy I used the opto22 stuff - it's huge, but you can pick whatever I/Os you want, and you get LEDs on them
[16:51:47] <skunkworks> yes
[16:52:10] <cradek> did you know john k has a zillion modules right now? if you're planning on using them, you could stock up.
[16:52:42] <skunkworks> http://www.youtube.com/watch?v=c_BasGaFqHk
[16:53:19] <skunkworks> I bought a few from him. (30 some outputs and 11 inputs) we have a ton of inputs
[16:54:05] <cradek> yep that looks like the boards I have
[16:54:30] <cradek> oh that's new - you just got it going - neat
[16:55:01] <skunkworks> goofing around
[16:55:14] <cradek> the featured videos I get are "Deadly Quake", "Video of Chile", and "Sniff My Butt"
[16:55:24] <skunkworks> eheh
[16:59:26] <skunkworks> it has been flashing like that for a few days.. seems to be stable.. ;)
[17:00:52] <cradek> heh, looking at the old mazak video, I sure am glad I have a mechanical spindle orient
[17:02:32] <skunkworks> yes - we do also
[17:03:44] <skunkworks> did you see the video recently - he oriented the spindle the same way - but must have had less backlash. pretty quick
[17:04:42] <cradek> no - do you remember whose it was?
[17:07:19] <skunkworks> hold on - let me look - he said he hacked the mazak orent to get it to work ;)
[17:07:54] <robh> skunkworks, u mean my video?
[17:07:57] <skunkworks> http://www.youtube.com/watch?v=UlW1s2BNixo
[17:08:01] <skunkworks> yes - there we go
[17:08:05] <skunkworks> Hi rob
[17:08:10] <robh> http://www.youtube.com/watch?v=UlW1s2BNixo
[17:08:14] <robh> aah u found it
[17:09:58] <skunkworks> * skunkworks is the search master.. ;)
[17:10:08] <robh> i think if u could run the drive in closed loop vector for postion mode u could control it alot tighter
[17:11:00] <cradek> neato
[17:11:56] <skunkworks> I think that is quick enough
[17:12:42] <cradek> yep, looks great
[17:13:55] <robh> just running drive in frequency mode, as vector wount let me get to 8k
[17:14:24] <robh> i have encoder feedback for vfd which helps keeping speed i found under load
[17:14:26] <cradek> that is sure a simple tool changer motion
[17:14:51] <skunkworks> too simple... hmmmm ;)
[17:15:38] <cradek> neat video - I love it - looks like a very successful retrofit of a complex machine.
[17:15:49] <robh> next machine has random so much quicker tool change
[17:16:18] <cradek> yours isn't bad if the tools are in order... but with no prep it would be slow if they aren't.
[17:16:29] <robh> we are very pleased with the refit, our thanks goes out to you guys for putting your time into a grate bit of software
[17:16:30] <cradek> random is nice.
[17:17:05] <cradek> I can spot my rigid tap cycle anywhere, with that little downward motion back to the original height
[17:17:29] <robh> hehe makes a nice dog leg in the move
[17:18:01] <robh> but it picked up the marker pulse so quick which makes a big diff
[17:21:27] <cradek> bbl, off to build a staircase
[17:23:03] <CIA-2> EMC: 03jepler 07v2.4_branch * rff4f97372f11 10/src/po/fr.po: French translation update
[19:37:00] <skunkworks> building staircases rates right up there with trim.. (not something I go out of my way to do)
[21:02:40] <alex_joni> http://www.linuxcnc.org/images/fbfiles/images/Screenshot1.jpg
[21:05:44] <cradek> that looks perfectly useful, and I don't see why it's desirable to have it inside AXIS
[21:06:05] <cradek> yay for windowing systems where you can have more than one application
[21:06:20] <alex_joni> heh
[21:06:34] <alex_joni> I can imagine he has a space issue (judging by the screenshot)
[21:06:44] <alex_joni> but resizing axis would be just as good
[21:07:09] <micges> alex_joni: how is it cross on view done?
[21:07:32] <cradek> this guy hacked it into gqcam
[21:08:10] <micges> oh
[21:08:32] <alex_joni> yup
[21:08:37] <cradek> alex_joni: since about 1985 windowing systems can overlap windows! :-)
[21:09:01] <alex_joni> cradek: yes, but focus on the window underneath is not very common
[21:09:15] <alex_joni> unless you can set an always on top for the other window
[21:09:26] <cradek> umm X has always always had that
[21:09:39] <alex_joni> cradek: sorry, wrong wording..
[21:09:49] <alex_joni> not very common for people using non-X
[21:09:53] <cradek> put the camera view on top, move the mouse into the other window
[21:10:24] <cradek> sucks to be them, then - too bad only the privileged can afford to run X
[21:10:47] <cradek> sorry, I'm being that way again
[21:11:21] <alex_joni> heh, just let it all out ;)
[21:11:51] <cradek> I think the camera thing is cool - I'm glad he found a way to do it
[21:12:16] <cradek> I think it's unnecessary to add it to AXIS, and unnecessary things should be avoided.
[21:12:20] <cradek> that's all :-)
[21:12:29] <alex_joni> I agree completely with that
[21:12:54] <alex_joni> but if he feels like hacking AXIS to integrate that, there's no-one stopping him either
[21:13:05] <cradek> no of course not
[21:13:21] <alex_joni> yay, bought a new handsfree for my cell
[21:14:25] <cradek> you kids first wanted your phones without cords, and now you're too lazy to even bother to hold the phone up.
[21:16:22] <alex_joni> http://www.chipchick.com/2009/12/sony-ericsson-mw600-review.html
[21:16:58] <alex_joni> I like to talk on it in the office, with my cell plugged into mains
[21:16:59] <cradek> bizarre
[21:17:12] <alex_joni> less cell radiation too, fwiw
[21:17:13] <cradek> why not plug a headset directly into the phone?
[21:17:20] <alex_joni> cables get into my way
[21:17:21] <cradek> this seems to be wireless for no reason
[21:17:32] <cradek> but this has the same number of cables (one to each ear)
[21:17:33] <alex_joni> oh, loads of reasons
[21:17:50] <alex_joni> I had a previous model
[21:18:00] <alex_joni> also wireless, but with a bit longer cables
[21:18:05] <cradek> oh you can leave the phone plugged in, on the desk, and not be tied to it
[21:18:10] <alex_joni> right
[21:18:23] <alex_joni> or deep in your pocket in the car
[21:18:35] <cradek> hmmm
[21:18:43] <cradek> ok :-)
[21:18:45] <alex_joni> you also see who's calling on the display
[21:19:23] <alex_joni> I keep the phone in my backpack while riding a bike, and love using it for listening to music
[21:19:51] <alex_joni> anyways, tried the cable headphones these last 2 days (since my other one stopped working)
[21:20:02] <alex_joni> they're such a hassle :)
[21:21:03] <alex_joni> * alex_joni stops spamming the channel :/
[21:21:45] <skunkworks> wait - you can mouse over a window in x and it will be the active window even though it is behind?
[21:22:24] <alex_joni> skunkworks: sure you can, although in ubuntu that's not enabled by default
[21:22:43] <cradek> skunkworks: you're making me cry
[21:22:50] <alex_joni> that was the original X way.. but people coming from windows prefer click to focus
[21:23:00] <alex_joni> so that's the default these days
[21:23:24] <skunkworks> heh
[21:23:30] <alex_joni> cradek: I think it's just like with clothes or shoes
[21:23:30] <skunkworks> is it easy to change?
[21:23:42] <cradek> system / preferences / windows / [ ] Select windows when the mouse moves over them
[21:23:45] <alex_joni> it'll get back in fashion after 30years or so
[21:23:59] <skunkworks> that seems like a neat idea... ;)
[21:24:32] <cradek> skunkworks: yeah it's nice. you don't have to bring a window to the top unless you want it at the top.
[21:28:30] <skunkworks> there have been times when I wanted to jog emc while keeping halscope up.. duh
[21:28:46] <cradek> welcome to the future
[21:29:25] <cradek> dang I never made the connection
[21:29:55] <cradek> is THIS why people think everything needs to be in one application window? they're used to Windows-like keyboard focus?
[21:30:23] <skunkworks> yes
[21:30:29] <cradek> it's so irritating to me (and I change it so fast) that I forget other people use it that way
[21:30:54] <cradek> jeez
[21:30:55] <alex_joni> cradek: you'd be surprised :)
[21:31:08] <alex_joni> I've seen people who only use maximized apps
[21:31:26] <alex_joni> they can't imagine resizing a window.. just switching from one to another
[21:31:52] <cradek> I bet mac makes you raise the window to the top, too
[21:32:05] <cradek> I bet it's what makes the titlebar thingy switch to be your app
[21:34:02] <cradek> I've used nothing but X for > 15 years...
[21:36:22] <skunkworks> it is all clear now isn't it ;)
[21:36:48] <cradek> I'm still sad though
