[01:07:35] <RyanS> archivist could it be possible that motor manufacturer went cheap inside the junction box and just used a generic terminal block. Perhaps it's just a matter of changing the terminal block for one with straps?
[01:54:13] <xxoxx> hi
[01:54:36] <xxoxx> can feed rate be tied to spindle encoder reading ?
[01:54:57] <xxoxx> manually control spindle speed, and thereby control the feed rate of the entire program ?
[01:55:27] <xxoxx> much like how old manual lathe works, except the XY axis is cutting a pattern
[01:56:08] <Jymmm> for knurling?
[01:56:35] <xxoxx> not just knurling
[01:56:45] <xxoxx> for general cutting, lathe and mill
[01:57:29] <xxoxx> basically could slow down even stop the program, just by manually dialing down the spindle
[01:57:50] <xxoxx> for retrofit lathes and mills
[02:28:58] <_DJ_> moin
[02:29:45] <Jymmm> Ug
[02:39:12] <_DJ_> hoi Jymmm :)
[02:40:10] <Jymmm> =)
[03:24:11] <archivist> RyanS, no, cheap means not extending the wires to the terminals
[03:42:21] <zoni1983> hi
[03:43:29] <zoni1983> anybody experience with pid tuning
[03:44:18] <zoni1983> i have 5i20 with 7i33
[03:46:33] <zoni1983> is any one there
[03:50:18] <kengu> hello. no.
[03:50:58] <zoni1983> need help with pid tuning
[04:00:39] <archivist> have you seen
http://gnipsel.com/linuxcnc/tuning/index.html
[05:03:19] <archivist> xxoxx, you have g33 for when you want geared behaviour
[05:04:17] <archivist> or what are you really trying to do, because you can tie axes together in hal
[05:07:05] <xxoxx> archivist, thanks. I think that's what I wanted.
[05:07:10] <xxoxx> thanks for the pointer
[05:10:15] <archivist> I do some strange stuff where arbitory gearing of axes by equation would be nice
[05:13:32] <xxoxx> yep... in my case e.g. hobbing, semi-manual patterns etc...
[05:16:04] <archivist> did you see the wiki page for hobbing
[05:16:53] <archivist> in that case it has been done with hal gearing and a pyvcp spin box to poke it into hal
[05:17:43] <archivist> I do patterns in gcode (calling subroutines)
[05:25:36] <archivist> xxoxx,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hobbing
[08:00:35] <Jymmm> Any suggestions on a mens digital waterproof sports watch? solar and atomic would be nice
[08:00:55] <jdh> G-Shock
[08:01:04] <Jymmm> that too
[08:02:05] <jdh> http://www.gshock.com/watches
[08:03:05] <jdh> timex iron-man also
[08:04:03] <Jymmm> I'm on amazon atm, 300+ casio (gshicks)

[08:06:58] <archivist> get cheap watches, you dont worry when they get damaged
[08:07:07] <Jymmm> archivist: =)
[08:07:36] <Jymmm> 3/4 in thick. lol
[08:07:41] <jdh> I've taken G-Shocks 250+ft deep with no problems.
[08:08:08] <Jymmm> jdh: But have you truned a corner and smacked it into something really hard?
[08:08:43] <jdh> nope, I haven't worn a watch in years in real life.
[08:08:52] <Jymmm> like a forklift
[08:09:46] <Jymmm> Yeah, me neither, but timer/stopwatch have been coming in handy lately
[08:10:10] <jdh> I have a bunch of those on my phone.
[08:10:42] <Jymmm> me too, but it doens't like my shower too much
[08:11:16] <jdh> I don't guess I need to know what you are timing in the shower.
[08:11:37] <Jymmm> and I dont carry my phone around the house. no no, just waterproof
[08:11:39] <jdh> get a Samsung Galaxy S4-Active, it is showerproof
[08:11:57] <Jymmm> is it? looking...
[08:14:36] <Jymmm> jdh: I don't think so, heh...
http://reviews.cnet.com/smartphones/samsung-galaxy-s4-active/4505-6452_7-35783536.html
[08:16:14] <jdh> ?
[08:16:24] <Jymmm> 1m
[08:16:35] <jdh> you have a shower deeper than 1m?
[08:17:10] <Jymmm> If I'm gonna pay $700, it's going smiwwing too!
[08:17:31] <Jymmm> underwater photography
[08:17:33] <jdh> they are 'free' with 2yr contract
[08:18:26] <Jymmm> Yeah, no thanks. I'd get an otter box instead
[08:18:52] <jdh> me too, but that all seems like a lot of hassle for just wanting a stopwatch in teh shower.
[08:19:09] <Jymmm> *sigh*
[08:19:25] <Jymmm> I want a watch that I can wear all the time.
[08:19:42] <Jymmm> not that I'm timing something in the shower itself.
[08:19:48] <archivist> who needs a stopwatch ,just count to 10 and change hands
[08:19:58] <jdh> ironman is a little lower profile.
[08:27:00] <Jymmm> DickTracy watch

[08:38:45] <Jymmm> jdh: oh gawd... A watch to compliment the galaxy phone

[08:39:20] <Jymmm> jdh: ...with facebook notification *rolls eyes*
[08:56:31] <MacGalempsy> morning
[08:57:46] <MacGalempsy> anyone fixin to hunker down for the snowstorm?
[09:15:24] <MacGalempsy> everyone have a nice thanksgiving holiday?
[09:19:01] <skunkworks_> Yes - no real issues
[09:19:07] <skunkworks_> how about you
[09:22:49] <MacGalempsy> was smooth sailing, not too cold in CA
[09:23:15] <MacGalempsy> but we returned and tomorrow or the next days is the beginning of a 4+ day cold streak
[09:24:24] <MacGalempsy> skunkworks_: no family knife fights this year?
[09:24:48] <skunkworks_> heh - no
[09:25:28] <MacGalempsy> thats always good
[09:59:24] <Jymmm> skunkworks_ just has family equipment fights
[10:00:19] <archivist> too heavy to throw
[10:01:06] <Jymmm> Nah, he just spins the tool changer up to 2000rpm then uses it like a sling
[10:01:31] <Jymmm> and on the K&T.... that's gotta hurt!
[10:04:07] <Jymmm> http://electronicsam.com/images/KandT/conversion/toolchangerspindle.JPG
[10:07:55] <Jymmm> skunkworks_: How did this happen?
http://electronicsam.com/images/KandT/conversion/testing/oops.JPG
[10:09:45] <dep> bonjour tout le monde
[10:10:34] * archivist passes a link to google translate
[10:10:55] <skunkworks_> Jymmm, actually - it was caused by the HD getting redirected sectors and the var file was coruped so the tool change position was wronge.
[10:10:57] <dep> hello
[10:11:11] <dep> i need help to configure my lathe
[10:11:27] <dep> i have a tool changer, I'm newbee
[10:11:35] <Jymmm> skunkworks_: Nice.... you should now sell it as "art" =)
[10:11:40] <Jymmm> ...digital art =)
[10:12:01] <archivist> dep just ask the actual questions
[10:12:41] <dep> sorry It's my first time on IRC
[10:13:08] <archivist> welcome to IRC
[10:13:26] <dep> TKS
[10:14:21] <dep> I retrofited an EMCO TURN PC 50
[10:14:47] <dep> i've changed all of elecronical parts ...
[10:14:53] <jthornton> you posted on the forum right?
[10:15:20] <dep> Yes, on linuxcnc.org forum
[10:16:35] <MacGalempsy> dep: have you made anything yet?
[10:17:26] <dep> for the tool changer, I have 3 pins, one output on N°6, and two input on N°10 and N°11
[10:18:05] <dep> the output give at the lathe the information to go to the next position tool
[10:18:40] <dep> and the input N°10 return that the tool changed
[10:19:06] <dep> and the input N°11 return just the position of tool N°1
[10:19:57] <archivist> dep you probably need to use classicladder to control the tool changer
[10:20:09] <dep> first: I don't understand how I can do the relation between G-code M6 T1 and the hard commande ....
[10:20:21] <dep> what is classic loader
[10:20:34] <dep> sorry Classicladder
[10:20:56] <jthornton> http://linuxcnc.org/docs/html/ladder/classic_ladder.html
[10:21:07] <jthornton> http://linuxcnc.org/docs/html/ladder/ladder_examples.html
[10:21:13] <archivist> often used to control tool changers
[10:21:49] <jthornton> and a lathe tool changer example
http://gnipsel.com/shop/hardinge/hardinge.xhtml
[10:22:18] <jthornton> and a lathe tool changer sim
http://gnipsel.com/linuxcnc/index.html
[10:22:25] <jthornton> scroll down on that page a bit
[10:22:44] <jthornton> dep got all that?
[10:24:29] <dep> Yes i'am reading this page and download zipfiles turretchanger
[10:24:49] <jthornton> that will keep you busy for a while I'm sure
[10:24:50] <dep> I never use some programm language
[10:25:16] <dep> i'm french mechanical man ;-)
[10:30:36] <dep> I think for the moment, i have put a push button on a front panel for manuel command to rotate the turret ... I'm so newbee to understand EMC2 programmation ...
[10:31:45] <dep> thanks you for your help, but I think I'm not competent for this job :-(
[10:32:53] <jthornton> well it will take some time to understand it all, but try the sample sim and open the ladder up and observe it while you press the tool change buttons
[10:34:21] <dep> how I can open the ladder in linuxcnc
[10:34:44] <jthornton> from the menu
[10:34:57] <dep> Ladder is like a grafcet no ?
[10:36:13] <jthornton> Classicladder can do grafcet but the examples use ladder logic
[10:37:10] <dep> I need to tick an option at the beginning of EMC2 congiguration to have ladder in menu no ?
[10:39:22] <jthornton> not in the example
[10:39:33] <jthornton> are you talking about the Stepconf Wizard?
[10:40:57] <Jymmm> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Sample_HAL_And_ClassicLadder
[10:42:23] <dep> yes stepconf wizard
[10:43:02] <jthornton> yes, I think there is an option to add Classicladder there IIRC
[10:44:39] <dep> Tks guys, I must to try that in my home...
[10:44:39] * jthornton goes back to work now
[10:45:02] <dep> I must to leave now, tks so much
[10:45:17] <dep> I hope I can do somethinks ...
[10:45:29] <dep> sorry for my poor english
[10:46:13] <archivist> our french would be much much worse :)
[10:46:43] <dep> ;-)
[11:48:59] <flughafen> I understand there are some german people in this channel?
[11:49:56] <cradek> sure, probably so
[11:50:54] <Spida> flughafen: ja
[11:51:07] <flughafen> are there any decent cnc kits in germany?
[11:55:35] <kengu> flughafen: you need to give a bit more information
[11:55:50] <kengu> but off if go..
[11:56:15] <flughafen> inexpensive kits < 3000€
[12:08:11] <mrsun> hmm getting joint 1 limit error when trying to use a microswitch for home+limits :/
[12:08:43] <mrsun> need to update the linuxcnc also i think, its like 4 years old now .. if there has come any updates that is :P
[12:11:30] <IchGuckLive> hi all B)
[12:11:53] <flughafen> morgen!
[12:11:55] <flughafen> oder abend
[12:12:07] <flughafen> ich kann nie mich errinern
[12:12:07] <IchGuckLive> hi that sounds German !!
[12:12:14] <IchGuckLive> ich sitz in kaiserslautern
[12:12:23] <flughafen> Nürnberg in ze haus
[12:12:39] <IchGuckLive> language here in english
[12:12:49] <IchGuckLive> whats up
[12:12:56] <flughafen> Nothing, whats up with you?
[12:13:01] <IchGuckLive> mill or turn or ?
[12:13:24] <IchGuckLive> im in good shape awaitning snow tomorrow
[12:13:25] <flughafen> I am fräs-less
[12:13:37] <IchGuckLive> so why you are hre
[12:13:58] <flughafen> was interested in some info on cnc kits in my heimatlands
[12:14:17] <IchGuckLive> oh there are alot of
[12:14:25] <IchGuckLive> from laser to plasma
[12:14:41] <IchGuckLive> from 3D printing to scuptunrn
[12:14:57] <IchGuckLive> lots of german do CAD CAM
[12:14:59] <flughafen> I'm not really into 3d printing, (at least not for 20+ years)
[12:16:19] <IchGuckLive> hard to tell if ther is no way to the goalline
[12:16:27] <archivist> kit to make what, often a lot of us retrofit something
[12:16:44] <IchGuckLive> PCB milling sculpt ...
[12:16:48] <flughafen> a cnc kit, not to retrofit, the whole frame/electronics/everythign
[12:17:02] <IchGuckLive> protos
[12:17:10] <IchGuckLive> or cnc-shop
[12:17:13] <archivist> flughafen, to make what though
[12:17:25] <IchGuckLive> querry in german
[12:17:34] <flughafen> ha
[12:17:41] <flughafen> i'd actually prefer to speak in english
[12:17:43] <IchGuckLive> hit my name
[12:17:50] <flughafen> ich bin deutscher aber in den usa aufgewachsen
[12:18:02] <flughafen> und mein deutsch ist sehr komisch
[12:18:27] <Loetmichel> flughafen: we germans dont mind
[12:18:40] <flughafen> so, I think it would be awesome if i could build a small engine , like a 2 stroke r/c engine
[12:18:42] <Loetmichel> our english is "strange", also ;-)
[12:18:44] <flughafen> ha
[12:19:15] <flughafen> whenever a german says "my english is terrible," it ends up being much better/nicer than listening to americans speak
[12:19:20] <archivist> flughafen, so you want a milling machine and a lathe
[12:19:47] <jdh> or at least a lathe.
[12:19:52] <Loetmichel> flughafen: tell me about it, my wife was english/german teacher (hischool) once
[12:19:53] <flughafen> why not a 4 axis?
[12:20:06] <flughafen> or is this what you mean?
[12:20:24] <IchGuckLive> flughafen: look into the querry given adresses
[12:20:30] <archivist> lathe for turning round stuff
[12:20:42] <Loetmichel> ... every time i am at hom and talking on the phone with some american/english suppliers i hear "WRONG!" yelled across the flat all five sentences ;-)
[12:21:17] <Loetmichel> s/all/every
[12:21:28] <archivist> usually german speakers english is very good except for one in here :)
[12:21:33] <flughafen> well, i know what a lathe is, but when you say lathe, do you mean, a 4th axis to a cnc? or a separate lathe?
[12:22:00] <IchGuckLive> flughafen: Drehbank
[12:22:04] <flughafen> ok, thanks
[12:22:07] <Loetmichel> flughafen: depends. i have a lathe that could fit as 4th axis on my mill ;-)
[12:22:11] <jdh> you could build it with just a lathe
[12:22:53] <archivist> lathe make better circular parts usually
[12:23:14] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=520 <- REALLY tiny ;-)
[12:23:34] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14058 <- thats me working on it ;-)
[12:23:51] <jdh> is that a sieg c1?
[12:23:58] <Loetmichel> c0
[12:24:07] <jdh> heh
[12:24:11] <flughafen> your beard and the material look the same
[12:24:19] <archivist> cant tell beard from swarf
[12:24:25] <jdh> acrylic?
[12:24:34] <Loetmichel> acrylics
[12:24:40] <Loetmichel> -s
[12:24:58] <Loetmichel> Plexiglas (r) to be precise
[12:25:05] <jdh> I turned a canister lid out of acrylic, it looked much the same.
[12:25:45] <jdh> I like that finger over the e-stop
[12:25:49] <Loetmichel> i milled a whole 5,25" USB-port insert from it
[12:26:36] <Loetmichel> jdh: better safe than sorry ... especially after having removed the shhield over the collet ;-)
[12:27:27] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12843 <- thats the end result
[12:27:28] <flughafen> ~does anybody here mill in their apartment?
[12:27:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10886
[12:27:47] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10883
[12:27:55] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10880
[12:28:02] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10877
[12:28:07] <Loetmichel> flughafen: here, i do
[12:28:10] <archivist> flughafen, does kitchen and small bedroom count :)
[12:28:16] <Loetmichel> much to the dislike of my wife ;-)
[12:28:33] <archivist> old free and single here to nagging
[12:28:39] <archivist> to/no
[12:29:51] <archivist> small lathe is in the kitchen, baby 5 axis mill in the small bedroom
[12:29:51] <flughafen> haha
[12:30:10] <Loetmichel> archivist: i really cant complain: my wife earns the big bucks over here, so she pays the rent and everything, and i have my owb room in the flat for working
[12:30:15] <flughafen> I have a garage, but it has no power(is this common in germany?) and the garage is too far away for an extension chord
[12:30:21] <flughafen> archivist: what 5axis do you have?
[12:30:22] <Loetmichel> and MY income is completle for myself ;-)
[12:30:38] <flughafen> I am married but we have separate bank accounts
[12:30:42] <archivist> flughafen, a fugly homebrew
[12:30:47] <Loetmichel> flughafen: my garage(s) have also no power
[12:31:00] <flughafen> i find this no power in the garage _VERY_ annoying
[12:31:06] <archivist> wire it
[12:31:24] <flughafen> by tapping into what?
[12:31:26] <Loetmichel> but they are just across the yard, so that will be remedied soon, as i get permission from the landlord to dig a bit ;-)
[12:32:05] <archivist> the garage here had no power, we extended off the house ring main
[12:32:27] <flughafen> archivist: the house must be 150m away?
[12:32:53] <Loetmichel> this is a 4 flat house over here, and three garages across the yard. And rented
[12:33:12] <Loetmichel> so i better ask the landlord before i start digging.
[12:34:02] <flughafen> I might consider moving, but that will ofcourse cost money too
[12:34:32] <flughafen> http://www.kronosrobotics.com/krmx02/index.shtml <- i was also consdering building this
[12:34:50] <archivist> machine tools dont like cold garages, best kept in the warm
[12:34:53] <flughafen> for the size and weight it's reasonably priced, like 1800$ for all the parts
[12:35:14] <Loetmichel> flughafen: looks a bit weak to me
[12:35:17] <flughafen> archivist: I sleep with my werkzeug every night
[12:35:22] <archivist> wrong machine for engine making
[12:35:58] <archivist> that is a router for wood and plastic work
[12:36:09] <Loetmichel> especially the "linear ways"...(shudder)
[12:36:46] <Loetmichel> i think even my construction of "linear ways" will be more rigid than that... ;-)
[12:37:11] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8884
[12:37:12] <archivist> that makes my machine almost pretty

[12:40:34] <Loetmichel> archivist: thats a nice half ton of steel ;-)
[12:40:54] <Loetmichel> ok, quarter ton )
[12:40:56] <Loetmichel> :-)
[12:41:16] <uw> what do people use here to make square holes
[12:41:23] <archivist> file
[12:41:38] <archivist> or broach
[12:41:45] <uw> i need to make a tool that uses a square hole for 1/2" ratchet
[12:41:59] <uw> file sounds like it would take forever
[12:42:06] <uw> broach eh
[12:42:14] <archivist> for a one off a file can be the easiest
[12:42:20] <sirdancealo2> a square drill bit, obviously
[12:42:44] <uw> hurhrurhru
[12:42:52] <archivist> they do exist
[12:43:10] <archivist> horrid but do exist
[12:43:18] <flughafen> uw:
http://www.youtube.com/watch?v=ALiqAXiTQBg
[12:44:05] <uw> flughafen, i've watched like 1000 videos with this tool / principal but cant find where to buy one
[12:44:21] <uw> it's a triangle thing that rides in a square guide
[12:44:49] <archivist> by the time you get one you could have filed the hole
[12:45:14] <uw> filing sucks and would take me 10hrs with the file i have
[12:45:39] <archivist> you could also use your mill/lathe as a shaper
[12:46:02] <uw> is that what you mean by broach method?
[12:46:08] <archivist> no
[12:46:28] <Loetmichel> uw: i mill it and file the corners with a triangle file ;-)
[12:46:32] <archivist> broach requires a high force press
[12:46:55] <Loetmichel> or drill into the corners beforehand and mill out the rest, depending on the "sharpness" of the edge needed
[12:49:40] <archivist> uw how many items are you going to be making
[12:49:59] <uw> probably 20
[12:50:16] <uw> maybe more
[12:50:29] <uw> i know i need 5 right now
[12:50:47] <IchGuckLive> @ all the new Kinect is best voted for cheep 3D full scanner
[12:51:50] <uw> i wish i had the device that cuts square holes like in the video above
[12:52:22] <uw> I was going to just weld cheap sockets on to the tool and use the square end from them, but thats kind cheesy
[12:52:22] <archivist> uw
http://www.ebay.com/bhp/square-broach
[12:53:00] <archivist> some require pulling some require pushing
[12:53:03] <flughafen> are there any MEs in here?
[12:53:18] <archivist> for what definition of me
[12:53:26] <flughafen> mechanical engineer
[12:53:34] <archivist> doing what
[12:53:39] <flughafen> anything
[12:53:43] <uw> thanks archivist can i hammer this?
[12:53:47] <uw> i dont have press
[12:53:56] <flughafen> only with mjolnir
[12:54:01] <archivist> uw I use a drill press
[12:54:09] <uw> oh...thats a good idea
[12:54:14] <uw> thanks
[12:54:19] <archivist> but that is ver bad on the drill press
[12:54:23] <Loetmichel> flughafen: no power?
[12:54:24] <archivist> very
[12:54:46] <uw> yea thats true
[12:54:54] <uw> well now i know where too look anyway
[12:54:57] <Loetmichel> these broaches CAN be hammered with a small 1kg hammer... but they thend to "dont like that misuse"
[12:55:08] <archivist> they break
[12:55:57] <archivist> I had made one for a special job and snapped it
[12:55:58] <uw> i should watch some broaching videos on youtube
[12:56:28] <uw> i dont want to spend $150 and break the thing 10secs into it
[12:57:15] <archivist> no hammering then
[12:57:36] <Loetmichel> uw: you CAN do the setup i did when making a "pipe spanner" out of brass tube fort M3 nuts
[12:57:57] <archivist> I have keyway broaches and they are very good for the job
[12:57:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11795
[12:58:01] <FinboySlick> uw: you can probably get a decent little press for less than the price of those broaches.
[12:59:17] <Loetmichel> just use a piece of mild steel pipe with a fitting diameter, press a hard square piece in it , hammer it out... weld the resulting "square drive" to your tool... harden, done ;-)
[12:59:48] <Loetmichel> i just used a steel nut for the wrench pictured ;-)
[13:00:10] <archivist> forge the square hole
[13:00:19] <archivist> when red hot
[13:00:34] <Loetmichel> would be an option also, right
[13:00:42] <uw> i thought about that Loetmichel but idk if it will be strong enough for the application
[13:01:09] <uw> i have like 10 spark plug wrenches that look just like the one in your picture
[13:01:53] <Loetmichel> uw: eat more black bread ;-)
[13:01:54] <uw> also is that a quad rotor
[13:02:02] <Loetmichel> uw: it is
[13:02:12] <Loetmichel> hexa actually
[13:02:25] <uw> LOL whats black bread?
[13:02:30] <Gabriel_56> uw: I have not followed the topic, but there is the possibility of milling two L-shaped blocks and bolting or welding them together, maybe with a matching profile if precision is important.
[13:02:35] <uw> and wheres DJAY
[13:02:49] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12997 <- full view
[13:03:03] <Loetmichel> uw: "schwarzbrot"
[13:03:30] <uw> Gabriel_56, that's not a bad idea. it is for putting a custom tool on a 1/2" rachet
[13:03:59] <Loetmichel> http://www.duden.de/rechtschreibung/Schwarzbrot
[13:04:39] <uw> Wer nicht gerne Brot zum Frühstück? ;)
[13:05:02] <uw> it looks like pumpernickel
[13:05:06] <Loetmichel> it is
[13:05:09] <Loetmichel> more or less
[13:05:42] <Gabriel_56> uw: ah ok, so probably it would be too bulky :)
[13:06:15] <uw> Maybe Gabriel_56 maybe not. I'm tossing around ideas
[13:06:23] <uw> i'll probably buy that broach
[13:06:31] <uw> i need these pieces by next friday
[13:06:32] <Loetmichel> you can also work a while as a mason or in the moving business to gain the needed power ;-)
[13:06:48] <Loetmichel> uw: whre are you located?
[13:07:06] <uw> Loetmichel, i'm in NYC area. are you near DEEJAY?
[13:07:24] <Loetmichel> if you call 500km "near": yes
[13:07:26] <Loetmichel> ;-)
[13:07:43] <Loetmichel> he's more or less "around the corner"
[13:08:03] <IchGuckLive> uw i will be in yonkers for 2 days after xmas
[13:08:14] <uw> i'm going to germany next year and i swear i'm going to visit him LOL
[13:08:40] <uw> IchGuckLive, very cool
[13:09:04] <IchGuckLive> O.O
[13:09:23] <Loetmichel> uw: still i would use a steel block, drill 4 2mm holes in the corners of the half" square, drill a big 12mm hole in the middle and then saw/file the rest
[13:09:37] <Loetmichel> should go fast and for 5 pieces its not too much work
[13:09:53] <archivist> he want 20 + parts
[13:10:14] <Loetmichel> uw: i already met him a few times on copter conventions
[13:10:20] <Loetmichel> nice guy ;)
[13:10:34] <uw> Loetmichel, i'm planing on making 20 parts but need 5 by next friday. i'm thinking i might as well get the broach
[13:10:52] <Loetmichel> if you think you need it, do so
[13:10:55] <uw> Loetmichel, LOL i really dont know him. I was only teasin ;)
[13:10:58] <Loetmichel> do you have a CNC mill?
[13:11:06] <uw> Loetmichel, yes
[13:11:18] <Loetmichel> so why not doing it with the mill?
[13:11:32] <archivist> you can mill most of the square and finish off with the broach
[13:11:36] <Loetmichel> the corner can (and should be) " a bit free" anyways
[13:11:48] <uw> the rest of the tool is made on the mill but the square part i'll have to manually do
[13:12:08] <Loetmichel> just cut about a third of the mill tool diameter diagonally into the corner, done
[13:12:17] <Loetmichel> and use a 2mm max mill bit ;)
[13:12:20] <archivist> using a smaller endmill, slowly can get into the corners
[13:12:35] <archivist> effin slow though
[13:12:50] <Loetmichel> let me see if i have a vid...
[13:12:55] <uw> the cnc part is done with 3/8" end mill so it could do some of it
[13:13:05] <uw> still it's the corners i need to take care of
[13:14:13] <archivist> milling part of the square will reduce the press force you need
[13:14:44] <Loetmichel> have no video
[13:15:10] <Loetmichel> but what i meant: the corner shouldnt carry any force anyway, so no loss if youi mill them out a bit
[13:15:38] <Loetmichel> like this (wait a moment, painting it...)
[13:15:52] <uw> archivist, Loetmichel that is not bad ideas
[13:16:13] <uw> i just have to add it to tool path then still buy broach
[13:16:18] <uw> but that's for me to figure
[13:19:07] <uw> yea thats what i think i'll just do
[13:19:12] <uw> mill out as best i can then broach
[13:21:25] <Loetmichel> UW: i menat like this:
http://www.cyrom.org/palbum/main.php?g2_itemId=14535
[13:22:18] <Loetmichel> drill the 4 corners, than mill out the square
[13:22:33] <uw> oic
[13:23:20] <uw> the smallest mill i have is 3/16" (like 5mm)
[13:23:56] <Loetmichel> hrhr
[13:23:56] <uw> id have to change mills too because the rest is in 3/8"
[13:24:06] <Loetmichel> i just bought a few 0,3mm ones ;-)
[13:24:17] <uw> lol how do they not snap
[13:24:23] <Loetmichel> they do ;-)
[13:24:35] <Loetmichel> and of course tungsten carbide
[13:25:17] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11933 <- 0.4mm on the right ;-)
[13:25:29] <Loetmichel> aehm.. onm the left, of course
[13:26:29] <Loetmichel> 0,3mm is tha smallest i can use on my mill, runout of the chinese spindle comes into play after that ;-)
[13:26:34] <Loetmichel> beyond that
[13:27:42] <FinboySlick> Loetmichel: Must take a while to face a 12"x12" plate with one of those ;)
[13:27:56] <Loetmichel> FinboySlick: would do ;-)
[13:28:23] <uw> haha
[13:28:29] <Loetmichel> especially as they are with a "drill tip"
[13:28:30] <Loetmichel> ;-)
[13:28:43] <Loetmichel> not flat head
[13:28:59] <uw> what in/s rate do you get with them LOL
[13:29:07] <Loetmichel> hmm
[13:29:10] <uw> .01
[13:29:12] <Loetmichel> calculating...
[13:29:14] <uw> or mm/s
[13:29:45] <Loetmichel> about 0,25in/sec
[13:30:00] <Loetmichel> F600
[13:30:01] <FinboySlick> That's not bad.
[13:30:16] <Loetmichel> and 24kRPM ;-)
[13:30:18] <FinboySlick> I guess that's pretty much a factor of how fast you can spin it.
[13:30:21] <FinboySlick> Yeah.
[13:30:40] <uw> lol 24k
[13:31:01] <Loetmichel> its "pedal->metal" for that chinese spindle
[13:31:18] <Loetmichel> i COULD run them with 60krpm and would still be in limits of cutting speed ;-)
[13:31:50] <uw> i'm sure those chi bearings would squeal with joy
[13:32:04] <Loetmichel> they would, no doubt
[13:32:53] <Loetmichel> it is surprisingly quiet at 24krpm, though
[13:33:27] <uw> thats good
[13:33:28] <Loetmichel> https://www.youtube.com/watch?v=jMXxjT4nNxg
[13:33:59] <uw> looks good
[13:34:08] <uw> I will subscribe to you on youtube
[13:34:50] <uw> i read mixed reviews on those spindles
[13:35:01] <uw> just subscribed
[13:35:27] <Loetmichel> i have two: runout less than 0,01mm, no problem so far after a year of use... sheer luck, i suppose
[13:35:56] <uw> the price is good and that one is probably the same one i've looked at on ebay
[13:36:02] <Loetmichel> and it can do aluminium without a problem
[13:36:06] <uw> I'm guessing
[13:36:38] <Loetmichel> https://www.youtube.com/watch?v=jzOtqYhpHIM
[13:37:06] <Loetmichel> (careful. LOUD)
[13:39:03] <Loetmichel> and in acrylics its even silent:
https://www.youtube.com/watch?v=QNLjMg0Nitk
[13:39:04] <uw> is that lovejoy c
[13:39:59] <Loetmichel> ?
[13:40:15] <uw> the previous video is that a lovejoy coupling
[13:40:21] <Loetmichel> hmmm
[13:40:47] <Loetmichel> google says yes
[13:40:56] <Loetmichel> didtn know they were called that
[13:41:09] <uw> http://www.ruralking.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/0/6/061420111.jpg
[13:41:15] <uw> i think thats a brand name
[13:41:25] <uw> idk what they are generically called
[13:41:35] <FinboySlick> Spider coupling I think?
[13:41:52] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12846
[13:41:59] <Loetmichel> was made for this spindle
[13:42:22] <uw> oic
[13:42:36] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12821
[13:44:31] <Loetmichel> hmm, three prongs... would have been a solution, also... but it works with two, so why bother? ;-)
[13:45:16] <uw> sure they both are acceptable
[13:46:08] <Loetmichel> this small "spindle" does 30krpm also
[13:46:16] <Loetmichel> but gets a bit hot then ;-)
[13:46:25] <Loetmichel> (using normal roller blade bearings...)
[13:46:45] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12840
[13:48:47] <FinboySlick> Loetmichel: Would it be worth looking into oil bearings (like in a turbo) for that sort of speed?
[13:49:00] <Loetmichel> no
[13:49:17] <Loetmichel> not for a spindle designated as a gift for a friend ;-)
[13:50:08] <Loetmichel> but i washed the bearings with gasoline, put in some thin oil, and swapped the PE spider for a rupper one-> 45°c at 35krpm... thats ok ;-)
[13:50:29] <Loetmichel> rubber
[13:51:06] <FinboySlick> Loetmichel: Now for a real challenge, get it to do rigid tapping at that speed ;)
[13:51:30] <Loetmichel> FinboySlick: 0,2mm threads: no problem ;-)
[13:51:59] <archivist> you cannot stop it fast enough to reverse out
[13:52:07] <Loetmichel> (may need a big brake on top, though) ;-)
[13:53:05] <archivist> getting the encoder read properly would not be trivial
[13:53:53] <Loetmichel> archivist. depends on the cpr ;-)
[13:55:09] <FinboySlick> I can just imagine engaging the break and the machine doing a 180° turn on its stand.
[13:55:35] <Loetmichel> FinboySlick: btdt
[13:55:37] <FinboySlick> Inertia, thy be a cruel mistress.
[13:55:43] <archivist> there is a video of a friction welder tipping
[13:56:04] <flughafen> archivist: i'd like to see that, ha
[13:56:15] <FinboySlick> Yeah, I was going to ask for a link.
[13:56:45] <Loetmichel> had some 3kW siemens AC servos (about 30kg each) and accidentally ordered them to do " ONE full turn, maximum speed"... while laying on a wooden pallet without any fixing
[13:57:41] <FinboySlick> Loetmichel: So the shaft did a half turn in one direction and the body did a half turn in the other direction? ;)
[13:57:43] <Loetmichel> first the lights in the company got dark, then they got VERY bright, then you'd see a 30kg motor about half a meter up in the air ;-)
[13:58:36] <Loetmichel> (nice effect that the indramat servo amps could do regenerative braking) ;-)
[13:58:52] <FinboySlick> Loetmichel: when you do something stupid here, you buy pizza for the staff... I wonder what sort of pizza that would have cost you.
[13:59:05] <Loetmichel> i WAS the staff ;-)
[13:59:28] <FinboySlick> So you should have treated yourself to a pizza!
[13:59:53] <FinboySlick> Loetmichel: BTW, are you sure you haven't moved to Sweden?
[14:00:02] <Loetmichel> i am, why?
[14:00:09] <FinboySlick> Loetmichel: You have too much sense of humour to be German today.
[14:00:24] <FinboySlick> You're breaking my carefully crafted stereotypes.
[14:00:37] <Loetmichel> i have to nuch sense of huor to be anywhere.
[14:01:10] <FinboySlick> See? Your German roots subconsciously prevented your brain from typing 'humour' right.
[14:01:16] <flughafen> haha
[14:01:24] <Loetmichel> you know what the germans say: "wenns nicht so traurig wär' würde man stundenlang lachen!"
[14:01:29] <flughafen> that's funny, and I know funny, I am a german
[14:02:02] <Loetmichel> "one would laugh all day if it wasnt so sad"
[14:02:31] <Loetmichel> i think life is much easier when laughing at things you cant change and change things you can ;-)
[14:02:54] <FinboySlick> Loetmichel: This is why we have clowns in government ;)
[14:03:57] <flughafen> yeah, maybe germans have no humor, but the mayor of nürnberg has not been caught smoking crack ;)
[14:04:13] <Loetmichel> flughafen: so what?
[14:04:49] <Loetmichel> coke, crack, H, whatever it suits their needs. as long as they are douing their jobs thats fine with me
[14:05:05] <Loetmichel> -it
[14:05:44] <FinboySlick> Hmmm... "as long as they are doing their job" is a tricky bit.
[14:11:08] <FinboySlick> archivist: Remember my 'crooked mill' problem?
[14:11:25] <FinboySlick> (how could you forget ;)
[14:15:04] <flughafen> i dont have any mill :(
[14:15:36] <FinboySlick> flughafen: Hehe, if you want to buy mine, feel free.
[14:15:53] <flughafen> for 50$?
[14:15:59] <FinboySlick> Might be a pretty steep shipping fee.
[14:16:01] <flughafen> it'll cost more to ship it to me than the mill itself ;)
[14:17:34] <FinboySlick> Holy crap, these guys are moving up in the world:
http://www.syil.com.cn/
[14:17:44] <FinboySlick> That's a bit of an upgrade from my mill.
[14:18:40] <flughafen> are servos generally better than stepper motors?
[14:18:47] <FinboySlick> Ah, no, they just built a fancy box around the crappy mill.
[14:19:06] <FinboySlick> flughafen: Yes, but they're also a bit more complicated to deal with.
[15:25:06] <FinboySlick> sheesh, harmonic drive gears are pretty darn expensive.
[15:39:47] <CaptHindsight> FinboySlick: can you use used robot parts?
[15:40:48] <FinboySlick> CaptHindsight: Sure. I'm just pondering a head-tilting mechanism for my mill. If I'm going to take it all apart I might as well improve it.
[15:41:00] <FinboySlick> I'd need something pretty thin though like:
http://www.ebay.com/itm/HD-40-120-900085-HARMONIC-DRIVE-SYSTEMS-GEAR-GEARHEAD-REDUCER-/281012526223?pt=LH_DefaultDomain_0&hash=item416da6dc8f
[15:44:54] <CaptHindsight> FinboySlick: whats your budget? What accuracy and repeatability? How much torque?
[15:46:28] <CaptHindsight> you might not be happy with harmonic drive specs for milling
[15:46:30] <FinboySlick> CaptHindsight: No idea. This is a long term idea, not something I plan to do this weekend. I expected the gear to be around 200 bucks. Obviously, as little backlash and highest repeatability possible. This is a 24k high speed spindle so I don't suspect it would need enormous torque.
[15:47:24] <mrsun_> yeah! got homing working for X and Y so far ! =)
[15:47:47] <FinboySlick> CaptHindsight: Could I use a dual-pinion spur gear to eliminate backlash?
[15:48:32] <FinboySlick> A bit like the do with spring-loaded rack/pinion setups on router tables.
[15:48:45] <CaptHindsight> be back in a bit
[15:55:10] <WalterN> yay, more work for the shop
[16:23:43] <Deejay> gn8
[18:35:41] <MacGalempsy> evening
[18:36:41] <Tom_itx> yes it is
[18:37:22] <MacGalempsy> hi Tom_itx. anything exciting happening?
[18:37:36] <Tom_itx> just a bit of wiring
[18:38:47] <MacGalempsy> on?
[18:39:42] <Tom_itx> the mill
[18:41:07] <MacGalempsy> pic of setup?
[18:42:06] <Tom_itx> just my sherline
[18:42:30] <MacGalempsy> nice. what kind of wiring?
[18:42:41] <MacGalempsy> .... are you working on?
[18:43:03] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[18:43:11] <Tom_itx> there's the new enclosure i'm working on for it
[18:43:18] <Tom_itx> tesing some boards
[18:48:47] <Jymmm> Tom_itx: Just be aware that most IEC connectors are not rated over 5A.
[18:51:41] <Jymmm> Tom_itx: And I do understand the reasoning for your placement of the power switch, but it's terminals are exposed at the edge of the door which may not be a good thing if anything was to fall in without you realizing it.
[18:52:48] <Tom_itx> yeah i plan to cover that
[18:54:22] <Jymmm> Tom_itx: If you can find some, 2-3" shrink tubing would work
[18:54:28] <Jymmm> diameter
[18:56:12] <Jymmm> Tom_itx: It's a shame that you can't show off the shiny gecko drives too
[18:56:13] <Tom_itx> PCW, 5v vfield results in undervoltage error on sserial on the 7I71 but not on the 7I84
[18:56:35] <Tom_itx> would a firmware update do anything for that?
[18:56:59] <Tom_itx> the 7i43 is running ver 41 iirc
[18:58:43] <PCW> the 7I43 firmware is not important the 7I71 firmware doesnt support 5V (its a little silly on a 48 output relay driver)
[19:00:01] <Tom_itx> probably so
[19:00:22] <PCW> I suppose its possible but a TTL device like the 7I69 might make more sense for a 48 x5V interface
[19:00:23] <Tom_itx> the docs indicate a field voltage from 5-28v
[19:01:07] <PCW> it may have been intended I will check
[19:01:37] <PCW> it may also be bad or funny since its a proto
[19:01:50] <Tom_itx> yeah i'm not that worried about it
[19:01:59] <PCW> though it seemed to work as AFAICT
[19:02:01] <Tom_itx> i just wanted 5v on the 7i84 for sure
[19:02:20] <Tom_itx> and that one is ok
[19:02:42] <PCW> the 7I84 and 7i76 and 7i77 have the 5V change
[19:02:50] <Tom_itx> where do i see the encoder list? in halcmd show pin?
[19:03:44] <PCW> I need to check if the per input threshold has been implemented (someone on the forum wanted 24V Vfield but 5V inputs on some pins)
[19:04:24] <PCW> yes or in axis "show hal configuration"
[19:04:31] <Tom_itx> with split vfield on the 7i84 that's quite possible
[19:04:42] <Tom_itx> run one at 5 and the other at 24
[19:05:06] <NickParker> wooh i got ssh working it looks like
[19:05:22] <NickParker> now to just reboot with the 6i25 in, and fix this silliness
[19:05:23] <PCW> Yeah the forum guy has a 7I77 and it does not support split VFIELD
[19:07:36] <Tom_itx> single encoder on the 7i84?
[19:08:05] <Tom_itx> i see enc0 enc1
[19:08:24] <Tom_itx> and 4 analog just above that
[19:08:59] <NickParker> awww hell. my ssh doesn't work with the 6i25 in
[19:09:07] <Tom_itx> unexpected realtime delay
[19:09:13] <Tom_itx> just idling
[19:13:16] <PCW> Tom_itx: may be more I/O than you can do practically with a 7I43
[19:14:22] <PCW> although if you ran out of time, i would expect a sserial error (last command not complete or some such)
[19:14:33] <PCW> NickParker: do you have a 5I25 or 6I25?
[19:14:39] <NickParker> 6i25
[19:15:10] <PCW> a 5i25 is not recoverable in that state (bogus bit file) without JTAG
[19:15:40] <NickParker> is a 6i25?
[19:15:42] <PCW> a 6I25 is recoverable without JTAG
[19:16:02] <NickParker> how do I recover it?
[19:19:01] <Tom_itx> PCW that was with the 7i84 only
[19:19:21] <Tom_itx> only happened once
[19:19:55] <PCW> actually its probably unrelated to sserial
[19:20:17] <NickParker> mmm I believe my bogus bitfile had sserial still in the ModuleID array
[19:21:56] <PCW> nothing you do with the pin file can break the bitfile to the extent that the PCI bus is broken
[19:21:58] <PCW> there is some likely some global thing wrong to make such a broken bitfile
[19:22:48] <NickParker> That's good to hear, I don't want to have to worry about jamming it again while working on the pin file.
[19:22:56] <PCW> like wrong or no ucf file association.
[19:23:07] <PCW> (check the pad report)
[19:23:45] <Tom_itx> i had that happen once when i tried copying a bitfile i'd done with an external editor that already had an entry in the hostmot file
[19:24:10] <PCW> if the ucf file association is wrong the tools will cheerful assign a random pinout
[19:24:26] <PCW> without warning
[19:24:27] <Tom_itx> to save time, i wound up reinstalling the zip and copying the modified bit file _BEFORE_ i made the file entry
[19:25:33] <PCW> the chances that a random pinout will do anything but crash the system are small
[19:25:58] <NickParker> so how do i undo it?
[19:27:02] <PCW> so if you have a bad bitfile you need to prevent it loading at power up
[19:27:04] <PCW> There is no graceful way to do this but short out the EEPROM pins at power up (6 and 7 are suggested)
[19:27:50] <PCW> 7 is 3.3V and 6 is clock (but has a series resistor so you are not shoring the actual FPGA pin)
[19:28:29] <PCW> do not accidentally short to the nearby bypass
[19:29:13] <PCW> then you can use mesaflash in the recovery mode to re-flash the 6I25 with a working config
[19:30:15] <PCW> or get a JTAG programmer widget (a few bucks for a parallel port model)
[19:31:14] <NickParker> That sounds much safer, and I wouldn't be surprised if my dad has a JTAG programmer around somewhere, I think I'll go that route.
[19:34:03] <Tom_itx> how do i figure out an IO to PIN map for the 84? the pdf mentions 16..19 are for the encoders, are they paired as 16-18 and 17-19 for the quadrature MPG?
[19:34:25] <NickParker> alright we don't own one. Can you recommend a workable (cheap) one online PCW?
[19:35:22] <PCW> 16 ia A0 17 ia B0 18 is A1 19 is B1
[19:35:37] <Tom_itx> thanks
[19:38:27] <PCW> NOt sure how good they are there are a lot on Ebay from 8.49 up
[19:38:37] <NickParker> Wait PCW was the EEPROM thing you were talking about just the "BRIDGE EEPROM ENABLE" section of the 6i25 manual?
[19:39:01] <NickParker> I'm happy to try that. You said it was an ugly route so I thought you meant shorting 2 pins on some tiny chip, not moving a jumper.
[19:39:30] <PCW> http://www.ebay.com/itm/LPT-JTAG-XILINX-Buffered-Parallel-Programmer-Cable-for-iMPACT-FPGA-CPLD-/271075614688?_trksid=p2054897.l4276
[19:41:07] <NickParker> moving W5 did not fix my issue
[19:41:18] <PCW> Yes thats the bridge chip EEPROM jumper but you need to disable the FPGA EEPROM which is different (the pins are not too tiny = .050 pitch)
[19:41:58] <PCW> I think the few times I've had to do this I used a pencil
[19:43:23] <NickParker> Alright let's try it. Where are these pins?
[19:44:09] <PCW> U2 pins 6 and 7
[19:44:56] <PCW> U2 is a M25P80 8 pin SO package on the top right side of the 6I25
[19:47:23] <NickParker> ok found U2. So I want a pencil line between the top right 2 pins on it. I assume down is the PCI slot and up is the 26 pin header?
[19:48:08] <PCW> top pins are 5,6_pencil_ 7,8
[19:48:30] <NickParker> ok. Yeah I just found a picture of the pins for this chip, matches what you say.
[19:49:05] <PCW> not a pencil line the pencil tip between the pins as you power up
[19:50:06] <PCW> if you succeed you should get at least one red LED staying on
[19:50:32] <Tom_itx> PCW if the encoder is open collector will i need pullups on those inputs?
[19:50:41] <Tom_itx> i did when testing on my avr
[19:50:48] <PCW> Yes
[19:50:51] <Tom_itx> ok
[19:51:08] <PCW> they have 22K pulldowns
[19:51:22] <PCW> so you need stiffer pullups
[19:51:26] <Tom_itx> alright
[19:51:43] <PCW> 2.5V threshold
[19:52:23] <NickParker> PCW: oh that makes it trickier. Once it's done booting I can move the pencil though I hope?
[19:52:52] <PCW> Yes only for the second or so that the system powers up
[19:53:25] <PCW> a tiny screwdriver will do as well if you are careful
[19:54:48] <NickParker> alright it worked
[19:55:13] <Tecan> dont forget the final step
[19:55:21] <PCW> Then have to figure out the recover option of mesaflash
[19:55:58] <Tecan> i always forget the last step
[19:56:10] <PCW> the final step is dont do whatever it is you did before
[19:56:24] <Tecan> profit
[19:56:53] <PCW> yeah that would be different :-)
[19:57:43] <NickParker> should mesaflash --scanpci be able to see it?
[19:57:46] <NickParker> it can't.
[19:58:02] <PCW> no
[19:58:56] <PCW> thats why you need the recover mode
[20:00:11] <NickParker> ok i did mesaflash --device 6i25 --recover (known good bitfile) and it turned off the red lights
[20:00:25] <NickParker> still can't see it though. should i try restarting?
[20:00:56] <PCW> yes it only loads the bitfile at power up
[20:01:51] <PCW> bbl
[20:02:59] <PCW> well it will reload after recover but the BAR register are not initialized to its invisible
[20:03:14] <PCW> really bbl
[20:09:48] <NickParker> ok so the restart didn't change behavior, i've booted with the pencil again
[20:10:43] <NickParker> when i do sudo ./mesaflash --device 6i25 --recover fallback.bit i get "Board Name:6i25 Access via XIO2001 bridge"
[20:37:59] <NickParker> ok it can see a tiny bit, because sudo ./mesaflash --recover fallback.bit --device 6i25 gets the message above but sudo ./mesaflash --recover fallback.bit --device 5i25 gets device not found
[21:10:39] <Jymmm> Tom_itx: BTW, the new controller looks nice. Just need s few hundred blinky lights and you can call it the Robototron 4000 =)
[21:12:50] <Jymmm> ~~~ Sheet Metal Gauge Size Chart
http://www.custompartnet.com/sheet-metal-gauge
[21:21:22] <pcw_home> ./mesaflash --recover fallback.bit --device 5i25 gets device not found
[21:21:24] <pcw_home> is not expected to work since only 6I25s have a recovery option
[21:23:56] <pcw_home> Did the recover write work? (prints file header and indicates written blocks)
[21:54:19] <NickParker> oh wait should i be doing --recover --write or just --recover (filename)?
[21:55:01] <NickParker> ./mesaflash --recover fallback.bit --device 6i25 got "Board Name:6i25, Access via XIO2001 bridge" and nothing else bac
[21:55:07] <NickParker> it turned off the red lights though
[21:56:56] <NickParker> however, behavior stays the same
[21:57:03] <NickParker> on reboot i get no video
[21:59:14] <NickParker> brb pcw_home
[22:15:55] <NickParker> back
[22:25:49] <pcw_home> I dont think it wrote, It probably needs --recover --write
[22:26:42] <Tom_itx> encoder worked btw. thanks for all the help pcw_home
[22:37:11] <NickParker> --recover --write worked.
[22:37:23] <NickParker> rebooted, fallback.bit verifies and --scanpci recognizes the card as 5i25
[22:46:10] <pcw_home> yeah --recover just enables the alternate flash write method you still need --write
[22:46:32] <pcw_home> I dont use that often enough to remember
[22:47:34] <pcw_home> Tom_itx: the MPG encoder is 1x by default (for 100 count detented encoders)
[22:48:12] <Tom_itx> i just grabbed an encoder i had in a box to test with
[22:48:22] <Tom_itx> 500 count but it worked fine
[22:48:47] <pcw_home> Pretty sure you can set 4X modes (and many others) but the modes are undocumented
[22:48:58] <Tom_itx> the sserial probably isn't fast enough for much of an encoder is it?
[22:49:23] <Tom_itx> where would i look for that?
[22:49:28] <pcw_home> depends on the count size
[22:49:49] <Tom_itx> i've got a few of these 500 count ones i may put to use one day
[22:50:44] <pcw_home> I think the 7I84 encoders are limited to about 30-40 KHz by the RC inputs and 50 KHz sampling rate
[22:51:46] <pcw_home> really just intended for MPG use
[22:51:56] <Tom_itx> i just watched it in hal config and it counted up and down so the quadrature is working
[22:51:58] <Tom_itx> yeah i know
[22:52:13] <Tom_itx> i planned to move most of my pendant stuff over to it
[22:52:28] <Tom_itx> nothing on it would strain it
[22:53:02] <pcw_home> you have to spin the dial pretty fast to get 30KHz on a 500 line encoder
[22:53:30] <pcw_home> what that 900 RPM?
[22:53:37] <Tom_itx> i thought about putting one on the spindle which goes to about 3500rpm
[22:53:52] <Tom_itx> but that would require one off the 7i43
[22:53:58] <pcw_home> Yep
[22:54:19] <Tom_itx> the 84 looks like a great all around card
[22:54:51] <Tom_itx> would i be safe moving limits to it?
[22:55:16] <pcw_home> Were really happy we chose to do our digital input with an A-D :-)
[22:55:38] <pcw_home> Yes, its intended for limits
[22:55:40] <Tom_itx> i can see how that would be very handy
[22:56:26] <pcw_home> for example the normal input threshold is 1/2 VField
[22:56:29] <Tom_itx> probably not fast enough for pwm or stepgen
[22:57:15] <pcw_home> The outputs arent (but we have run tiny unipolar step motor from one for fun)
[22:57:24] <Tom_itx> yeah
[22:57:36] <Tom_itx> it might run a reprap but i don't plan to do one of those
[22:58:17] <Tom_itx> what's that little 6-8pin sot chip that bridges the cat5 input?
[22:58:41] <Tom_itx> i held it up to the light and saw the gnd plane surrounding it all but that chip
[22:58:49] <pcw_home> a ADUM isolator
[22:58:55] <Tom_itx> that must be the bridge across it
[22:59:54] <pcw_home> the 7I71 and 7I84 I/O is galvanically isolated from the serial link
[23:00:06] <Tom_itx> i read that
[23:00:50] <pcw_home> so thats a dual isolator (TX and RX)
[23:01:23] <pcw_home> good to 10 MBaud
[23:01:48] <pcw_home> (though normal sserial is 2.5 MB)
[23:02:06] <Tom_itx> should handle anything we could throw at it
[23:02:35] <pcw_home> you can set the remote baud rate to 10MB and they will work (but SSLBP needs to be set to 10 as well)
[23:02:49] <Tom_itx> firmware update?
[23:02:59] <Tom_itx> i don't really see a need for that
[23:03:22] <pcw_home> eventually we will add baud rate search to SSLBP 2.5,10,115200
[23:04:00] <Tom_itx> i figured sserial is still a work in progress
[23:06:25] <pcw_home> Were pretty happy with most of it now but there are a number of improvement we would like
[23:08:07] <pcw_home> (one is splitting the RX and TX parts of the transactions and auto starting RX transactions based on the DPLL)
