[00:07:21] <Jacky^> damn sony !
[00:07:26] <Jacky^> http://esupport.sony.com/perl/news-item.pl?mdl=DSCV1&news_id=95
[00:08:49] <Jymmm> Jacky^: That sounds pretty good of Sony to do that. They even cover the shipping costs. And usually it'll be replaced with a better unit.
[00:09:08] <Jacky^> Jymmm: bought a camera 2 week ago :(����������
[00:09:15] <Jacky^> E.400
[00:09:23] <Jymmm> Jacky^ Ok, so return it
[00:09:31] <Jymmm> and get another one
[00:09:51] <Jacky^> yes, need to understand if work or not before
[00:10:06] <Jacky^> .. but may be accelerated if they are exposed to hot and humid environments
[00:10:14] <Jacky^> what they mean ?
[00:10:38] <rayh_emc2> SWPadnos: not stepgen running on my system here.
[00:10:40] <Jymmm> Jacky^L Take it into a hot steam shower running in the bathroom
[00:10:41] <Jacky^> want to know how many time of warranties it have..
[00:10:48] <Jacky^> :(
[00:13:20] <SWPadnos_> rayh_emc2: not stepgen? are you using a USC or a UnivPWM?
[00:13:28] <rayh_emc2> ah. sorry swp I guess there wouldn't be one
[00:13:45] <SWPadnos_> no - jmk called them ppmc.0.stepgen<n>
[00:13:49] <rayh_emc2> USC is all I've got running here at the moment.
[00:13:51] <SWPadnos_> ok
[00:14:12] <SWPadnos_> I'm seeing problems as well, but they may be AXIS related - I'll switch to tkemc and see if they persist
[00:15:40] <Jacky^> Jymmm: other interested models PowerShot A60, PowerShot A70, PowerShot A75, PowerShot A300, PowerShot A310, Digital IXUS V3, Digital IXUS II, Digital IXUS IIs di Canon; FinePix S2 Pro Digital, FinePix A303, F410 e F700 di Fijifilm; Dimage 7i, 7Hi, A1, Xi, Xt, X20, S414 e F300 di Konica Minolta; Coolpix SQ, Coolpix 3100 e Coolpix 5700 di Nikon, nonch� le F717, U10, U20, U30, U60, DSC-V1 e la serie P di Sony.
[00:15:46] <Jacky^> gulp
[00:16:29] <Jacky^> a lot of brands other
[00:16:43] <SWPadnos_> and video - it's not just still cameras
[00:17:14] <Jacky^> do not bought that gift for christmas
[00:17:33] <Jacky^> buy
[00:19:03] <rayh_emc2> I wonder if it could be a problem with my ini. Shouldn't though.
[00:19:20] <Jacky^> rayh_emc2: :)
[00:19:42] <SWPadnos_> not sure - I'm not positive that everything is correct there (at least in the cvs ini/hal files)
[00:19:57] <rayh_emc2> last commit message Added an enable pin to the PPMC step generators, and updated the .hal file to us...
[00:20:14] <SWPadnos_> yep - they're there - I see it with halcmd
[00:20:48] <SWPadnos_> (btw - halcmd -kf gives you an interactive mode - type commands, get answers, doesn't bomb out on error)
[00:21:41] <rayh_emc2> Right. I used that in a tickle script but forgot to shut it down before closing emc.
[00:21:59] <rayh_emc2> It left all the kernel modules
[00:25:33] <SWPadnos_> well - I'm not getting feedback either, but if I change to encoder input, it works fine
[00:25:42] <SWPadnos_> I'll see if any steps are being output
[00:25:56] <SWPadnos_> hmmm - hold on a sec - that reminded me of something
[00:27:36] <SWPadnos_> ok - let me try with my test setup - I can send those files to you if you like
[00:28:09] <rayh_emc2> I can see the enable signals change when tkemc comes out of estop and to machine on.
[00:28:27] <SWPadnos_> yes - that happens
[00:28:37] <SWPadnos_> there are some scale variables that may be wrong though
[00:28:39] <rayh_emc2> Need to drive SO to town for a few. Yes send the files.
[00:29:09] <SWPadnos_> ok - can I dcc them to you now (they're short)?
[00:46:55] <jtr> emc/sreq
[00:47:38] <jtr> oops, sorry - reading about dcc and had something in the buffer.
[00:56:53] <Jacky^> uhm founded ice on mars
[01:12:40] <rayh_emc2> I'm back
[01:13:02] <rayh_emc2> SWPadnos_: I don't think I've got dcc setup right on my net.
[01:13:12] <SWPadnos_> ok - I decided to fiddle a bit anyway
[01:13:14] <rayh_emc2> I get the message that someone is trying to send me files
[01:13:25] <rayh_emc2> but I don't seem to be able to respond.
[01:13:29] <SWPadnos_> I never tried actually
[01:15:30] <SWPadnos_> just testing
[01:17:25] <rayh_emc2> connection refused
[01:17:35] <SWPadnos_> ok - I'll email in a little bit then
[01:17:58] <SWPadnos_> something may have gotten broken in the last commit, or my board has gone south
[01:18:45] <rayh_emc2> I do see the velocity commands in ppmc.0.stepgen ramp up when it tries to move.
[01:19:16] <SWPadnos_> I'm not seeing any step output at the moment
[01:19:36] <SWPadnos_> then again, I am seeing odd noise on the power supply line, so I need to do some hardware testing
[01:22:38] <rayh_emc2> axis.0.motor-pos-cmd ==> Xpos-cmd changes with jog but pos does not.
[01:25:09] <rayh_emc2> shouldn't Xpos-cmd be connected to ppmc rather than pid
[01:25:19] <SWPadnos_> yeah - the stepgens aren't outputting anything - I'm trying to figure out why
[01:25:38] <SWPadnos_> no - pid, these are servo-like
[01:25:50] <rayh_emc2> oops. I'm reading the wrong signal
[01:26:39] <rayh_emc2> float -2.50000e-04 Xpos-fb
[01:26:39] <rayh_emc2> ==> axis.0.motor-pos-fb
[01:26:39] <rayh_emc2> ==> pid.0.feedback
[01:26:40] <rayh_emc2> <== ppmc.0.encoder.00.position
[01:27:41] <SWPadnos_> ok - that's one count (probably) on the encoder
[01:28:01] <rayh_emc2> I keep getting a following error that causes estop
[01:28:04] <SWPadnos_> if you look at param ppmc.0.encoder.0.count, you should see -1
[01:28:15] <SWPadnos_> oops - encoder.00
[01:28:59] <SWPadnos_> oh so much better - plugging the scope into the same power strip as the USC and emc computer ;)
[01:29:14] <rayh_emc2> 05 float -W -2.50000e-04 ppmc.0.encoder.00.position ==> Xpos-fb
[01:29:14] <rayh_emc2>
[01:29:47] <rayh_emc2> 05 s32 -W -1 ppmc.0.encoder.01.count
[01:30:11] <SWPadnos_> yep - as I thought - one count of startup glitch
[01:38:00] <SWPadnos_> OK - I see that the step outputs are going - now to transfer some of the stuff from my test .hal file to an actual emc hal file
[01:51:45] <rayh_emc2> Hi Pete
[01:51:59] <petev> hi ray
[01:53:17] <Jacky^> night
[01:53:24] <Jacky^> Jacky^ is now known as Jacky^afk
[01:53:25] <rayh_emc2> catch you later.
[01:56:32] <skunkworks> I played with emc2 + axis tonight. No problems (still getting used to the interface). One comment is that I think the cone should stay the same size on the screen. when you zoom in the cone gets bigger and bigger. Just a comment - axis is awsome.
[01:57:08] <skunkworks> awesome
[01:59:13] <SWPadnos_> hey rayh_emc2, is the default jog speed is 1 IPM or 1 IPS?
[01:59:19] <jepler> skunkworks: we've considered a change like that. Right now, the cone's size is relative to the size of the g-code loaded.
[01:59:25] <jepler> SWPadnos_: 1 IPM I think
[01:59:29] <jepler> well, it comes from the inifile
[01:59:35] <SWPadnos_> ok - I'll look
[01:59:46] <jepler> though for all I know emc2 is different
[02:00:18] <jepler> jog_speed = float(inifile.find("TRAJ", "DEFAULT_VELOCITY"))
[02:00:22] <rayh_emc2> ipm
[02:00:32] <jepler> this is what AXIS uses to find the value to put in the jog message
[02:01:03] <rayh_emc2> Right and the user should set it higher if they want reasonable manual jogs
[02:01:11] <SWPadnos_> ok - I think I'm hitting a rapid bug in emc2, because I can do a g1Z1F1 without trouble, but a g0z1 gets following errors
[02:01:24] <SWPadnos_> maybe related to the jogging bug
[02:01:41] <fenn> SWPadnos: is default accel somewhat less than max accel?
[02:02:04] <SWPadnos_> yes - somewhat less
[02:02:14] <fenn> ok nevermind
[02:02:23] <SWPadnos_> but I'm just using a USC with step outputs looped back to encoder inputs - no machine hardware
[02:02:27] <skunkworks> I have not had any following errors sinse I have stopped using the jog at high speeds - Thanks axis ;)
[02:06:14] <SWPadnos_> interesting - default accel is 15, max accel is 20
[02:06:32] <SWPadnos_> hmmm - hold on
[02:06:45] <skunkworks> and I keep the max velocity less than ((1/base_period)/2)/input_scale <- think that is right
[02:06:49] <skunkworks> steppers
[02:11:03] <rayh_emc2> rayh_emc2 is now known as rayh-away
[02:31:13] <wb9mjn> Hi All...can somebody send me a file to see if the changes I just made have effected anything ?
[02:36:20] <SWPadnos_> yep
[02:37:23] <SWPadnos_> seemed to work
[02:37:40] <wb9mjn> OK...I m back to where I was...Can you accept a file ?
[02:37:51] <SWPadnos_> from some people ;)
[02:37:56] <SWPadnos_> go ahead and try
[02:39:45] <wb9mjn> Did you see a request yet ?
[02:39:56] <SWPadnos_> yes, and I accepted
[02:40:10] <wb9mjn> Ok..but the IP address was a 172.X.X.X ?
[02:40:20] <SWPadnos_> it's showing 0% complete though
[02:40:26] <SWPadnos_> yes - (
[02:41:05] <wb9mjn> Ok...still messed up...but I have upgraded my firewall/dsl box software...which I read is neccassary to eventually get DCC working...
[02:41:07] <SWPadnos_> ok - it shows it as failed now
[02:41:07] <wb9mjn> Thanks!
[02:41:13] <SWPadnos_> sure
[03:08:57] <wb9mjn> Just did some more firewall adjustment...
[03:09:04] <SWPadnos_> failed again
[03:09:07] <wb9mjn> Still not working...
[03:09:07] <cradek> you can try me
[03:09:09] <SWPadnos_> but faster this time
[03:09:11] <cradek> oh
[03:10:13] <wb9mjn> I have the DCC ports setup in the firewall now...now all I need is a client that will go out and fetch the real IP address and send the packets with it..
[03:10:29] <wb9mjn> Which according to what I read, mIRC does that or something similar...
[03:10:55] <SWPadnos_> I was getting addresses that look real - not common NAT (192.168.x.y) addresses
[03:11:10] <wb9mjn> Oh ? What was the address ?
[03:11:24] <SWPadnos_> and I note that the address in the send request and the acceptance are different
[03:11:34] <SWPadnos_> [DCC]Got DCC File Transfer offer from “wb9mjn” ( of “dm6nov05.jpg” (689 KiB) [Accept] [Decline].
[03:11:39] <SWPadnos_> [DCC]Accepted DCC File Transfer of “dm6nov05.jpg” from “wb9mjn” (
[03:11:53] <wb9mjn> No...that 172 is my LAN block here ...
[03:12:01] <wb9mjn> Its not a real address...
[03:12:09] <wb9mjn> So, it still has that problem...
[03:12:30] <SWPadnos_> ok, but the was different
[03:12:44] <wb9mjn> The address I m using right now is
[03:13:01] <SWPadnos_> I wonder where the 216 addr came from
[03:13:08] <wb9mjn> me too...
[03:13:36] <wb9mjn> That s probably the freenet node...
[03:13:53] <wb9mjn> Once the transfer is accepted, its probably out of their...
[03:14:31] <wb9mjn> Or that is your address ?
[03:14:40] <SWPadnos_> nope
[03:15:03] <SWPadnos_> wait - yep ;)
[03:15:20] <wb9mjn> Anyway....I have mIRC downloaded...I guess I ll try it...but after a month it costs money...hi..
[03:15:29] <SWPadnos_> you'd think that I would actually remember the address, since I'm paying extra for static
[03:15:44] <wb9mjn> back in a bit...
[03:15:46] <SWPadnos_> ok
[03:20:02] <wb9mjn> I m back...
[03:20:09] <wb9mjn> on mIRC...
[03:20:20] <SWPadnos_> ok
[03:20:52] <cradek> how does mirc get your outside address when it changes?
[03:20:54] <wb9mjn> Gotta figure how to do a transfer now...
[03:20:59] <cradek> ha
[03:21:10] <wb9mjn> And also how to turn on the localhost ? feature..
[03:24:37] <wb9mjn> I think it might be dfaulted on...Cradek, ready for a file ?
[03:25:06] <cradek> sure
[03:25:30] <cradek> yay!
[03:25:42] <wb9mjn> Yep it worked...That is a picture of my Y drive!
[03:25:58] <SWPadnos_> what am I, chopped lilver? ;)
[03:26:02] <SWPadnos_> liver
[03:26:47] <SWPadnos_> ooooohhh - shiny
[03:26:56] <wb9mjn> Its trying to you now...
[03:27:04] <SWPadnos_> I see some 80/20 extrusion there as well
[03:27:26] <wb9mjn> Wierd,,,I never got confirmation of the send ?
[03:27:34] <wb9mjn> Did you get it SWPadnos ?
[03:27:38] <SWPadnos_> I never got anything from you - only from cradek
[03:27:43] <wb9mjn> Ok...
[03:27:45] <SWPadnos_> you don't love me any more
[03:27:45] <cradek> I sent it to him
[03:27:52] <wb9mjn> Ok...
[03:27:59] <wb9mjn> I m trying to send to SWPadnos...
[03:28:14] <wb9mjn> Yea, the plate was raw bar stock....
[03:28:25] <SWPadnos_> or swpadnos_ ?
[03:28:32] <wb9mjn> So, I fly cut it flat...as it was convex as it was made by DM...!...
[03:28:55] <SWPadnos_> is that stainless flex conduit?
[03:29:02] <wb9mjn> Then I put in the additional counter bore and idler bearing...
[03:29:58] <wb9mjn> Nope, its just Tyco pastic waterproof conduit..
[03:30:08] <SWPadnos_> bummer
[03:30:30] <SWPadnos_> a friend has some nice stainless flex sheathing, that I think is liquid tight
[03:30:36] <SWPadnos_> I've been looking all over for it
[03:30:44] <wb9mjn> Yea, on the 8020...I bought about $300 bucks worth of it...Used some for the lathe table, and the rest on the
[03:30:46] <wb9mjn> mill...
[03:31:29] <wb9mjn> The pulleys are original from the DM, but the motor just happened to have a pilot bushing that fit
[03:31:33] <SWPadnos_> it's cool stuff. I have about 50-75 feet or so of the 1010 (used to be a trade show display)
[03:31:40] <wb9mjn> the belt slot in the DM plate....
[03:31:49] <wb9mjn> That is 2020 there...
[03:31:57] <SWPadnos_> yep - I see the two slots ;)
[03:32:01] <wb9mjn> Want to see the whole thing ?
[03:32:17] <SWPadnos_> sure - if cradek doesn't mind being a go-between ;)
[03:32:39] <wb9mjn> It actually cut meta for the first time tonite!...
[03:32:51] <SWPadnos_> cool
[03:33:04] <cradek> why can't you send to one another?
[03:33:12] <SWPadnos_> NAT -> NAT ?
[03:33:26] <cradek> should be fine...
[03:33:27] <wb9mjn> Takes a long time for some reason..but think we can now...
[03:33:36] <cradek> huh, strange
[03:33:39] <cradek> you're both fast for me
[03:33:49] <cradek> 14 secs to receive from wb, 4 to send to SWP
[03:34:05] <SWPadnos_> yeah - I was just going to ask you what your connection is (but I think I already did, some time ago)
[03:34:23] <wb9mjn> I m using an ADS 3M/.5M connection...
[03:34:26] <SWPadnos_> DS3 or some such lustful thing
[03:34:42] <wb9mjn> ADSL...
[03:34:54] <SWPadnos_> of course upload would be slower - it is *A* DSL
[03:35:01] <wb9mjn> Right...
[03:35:03] <SWPadnos_> I'm on 2.0/0.5 here
[03:35:08] <SWPadnos_> or 2.0/0.25
[03:35:37] <SWPadnos_> cool - you even have a chip shield
[03:36:00] <SWPadnos_> what's the work envelope? It looks like you have a fair amount of Z travel
[03:36:02] <wb9mjn> I actually knew what ADSL meant some time ago, as I helped calibrate Westell's T1 Test Sets when they made some of
[03:36:16] <SWPadnos_> heh - no offense intended :)
[03:36:36] <wb9mjn> the first ADSL equipment for - get this - Video on Demand....Telco execs were braindead back then (1994)...
[03:36:57] <SWPadnos_> still are, I think
[03:37:30] <wb9mjn> The traves are 7.6, 6.1 and 7.5 (xyz)...
[03:37:44] <cradek> I recall wanting 'net bandwidth already in 1994
[03:37:51] <SWPadnos_> ok - I thought the Z looked disproportionately large
[03:37:51] <cradek> but most people had never heard of it
[03:38:10] <wb9mjn> If I would have had a work table integrated into the motion table, it would have be 10 inches on the Z ...
[03:38:12] <cradek> although 33.6k dialup was still pretty fast
[03:38:18] <SWPadnos_> yeah - the only broadband was 128k ISDN, or a T1 (or higher)
[03:38:36] <SWPadnos_> or fractional T, for almost as much as a full T
[03:38:46] <wb9mjn> The Tslot (work) table is a precision european thing, with DIN 508 tslots in the x and y...all hardened...
[03:38:49] <cradek> our whole office was on a leased-line 28.8k fill-time modem connection
[03:38:59] <cradek> full
[03:39:04] <cradek> AND WE GOT USENET OVER IT
[03:39:15] <wb9mjn> I had counter bores added into the corner bolt holes, to be able to bolt it to the motion table...
[03:39:16] <cradek> totally unbelievable
[03:39:16] <SWPadnos_> talk about fill-time ;)
[03:39:43] <wb9mjn> I was on 9600 baud Ham Radio back then, hi !
[03:39:57] <wb9mjn> It worked ... but that was SLOWWW...
[03:40:21] <cradek> I think I was still getting news and email over uucp at home...
[03:40:34] <cradek> through work
[03:40:44] <cradek> not sure about the exact years here
[03:40:50] <wb9mjn> Yea, and Westell was cranking out these ADSL units back then trying to horn in on Cable TV...
[03:40:58] <cradek> funny
[03:41:02] <cradek> that sure hasn't worked out
[03:41:24] <SWPadnos_> kind athe opposite, in fact
[03:41:39] <wb9mjn> Well,,,it kinda has...allot of the work that went into it is resurfacing as mesh WIFI companies...
[03:42:11] <wb9mjn> Just because of the restrictive FCC rules, nobody could take a risk on Ham Radio with it...
[03:42:16] <SWPadnos_> all I want is the same thing they get in Japan - 100Mbit @ $35-50/month
[03:42:25] <SWPadnos_> and Korea
[03:42:29] <SWPadnos_> and Vietnam
[03:42:32] <SWPadnos_> and Taiwan
[03:42:35] <SWPadnos_> etc...
[03:42:42] <cradek> I'm thrilled with my service here
[03:42:53] <cradek> I get ~ 6Mb for ~ $50
[03:42:54] <wb9mjn> The packet satellites are quite unique in their capabilities too...Anywhere on the world, need a medium sized file..just stick
[03:43:05] <wb9mjn> up a quadfilar helix and wait a day...
[03:44:43] <wb9mjn> One of our ham packet guys ended up as a cofounder of one of the major cable tv internet access companies...
[03:44:56] <wb9mjn> Except he left before the big bucks flowed in...
[03:45:13] <SWPadnos_> I hate when that happens
[03:45:34] <wb9mjn> Went back to Tellabs...and had the startup put there cable access buisness out of buisness...
[03:46:00] <wb9mjn> He is really kickin himeself...
[03:46:53] <wb9mjn> Allot of the protocolls for home access over wired networks (PPP is one) were written for Ham packet radio originally...
[03:47:52] <wb9mjn> Anyway...the milling machine is all servos...does about 240 in/min...can do XYZ full travel simultaneously in about 3 seconds...
[03:48:09] <SWPadnos_> that's pretty quick
[03:48:11] <wb9mjn> Wonder if Les is up ?
[03:48:34] <wb9mjn> He was the one who wanted to see this...hi...
[03:50:12] <SWPadnos_> interesting to note that you have more Z travel than a Bridgeport (assuming the quill is CNC'd)
[03:50:53] <wb9mjn> Would like to have more, but that s going to be it...would like more X, but those linear bearing tables only came in
[03:50:55] <wb9mjn> one length...
[03:51:13] <wb9mjn> Its sticking the motor out the enclosure already , too...
[03:51:23] <SWPadnos_> yep
[03:51:39] <wb9mjn> When the guy had this on Ebay he misled everybody saying it had a 9 by 6 X and Y ...
[03:51:44] <SWPadnos_> the machine operating envelope goes way up when you increase the range
[03:52:14] <SWPadnos_> that's the table size, right? not motion envelope
[03:52:25] <wb9mjn> It actually only had 6 by 4 with the original cheapo asian Tslot table, with horribly modified NEMA 34 steppers...
[03:52:33] <SWPadnos_> odd
[03:52:49] <wb9mjn> The original stepper mounting was totally poor enginnering...
[03:52:59] <wb9mjn> No...the travels...
[03:54:06] <wb9mjn> SO, there was allot of competition, as people were thinking it had the same table travels as the $20K benchtop machines out there...
[03:54:23] <SWPadnos_> yep
[03:54:24] <wb9mjn> Anyway, I gave up on the original tables...
[03:54:33] <SWPadnos_> it's not too far off, but still wrong
[03:55:47] <wb9mjn> Well, area wise it was being sold 225 percent of what it was !
[03:56:15] <wb9mjn> Anyway...the stepper drive was a R/L drive...with big massive heat sinks in the back...
[03:56:20] <SWPadnos_> the table doesn't have to be as big as the travel - a Bridgeport has more Y travel than the table depth
[03:56:27] <wb9mjn> with monster power resistors mounted to them...
[03:56:43] <SWPadnos_> ugh - now that's cheap design
[03:57:17] <wb9mjn> And it was all just screwed into the blue box...no sub-panel...
[03:57:43] <wb9mjn> So, first thing I did was pull all that out but the power transformer, and add in a sub panel...
[03:58:24] <wb9mjn> Then put the SCR spindle drive back in, an Opto 22 board, and 4 Gallil servo amps...
[03:58:38] <wb9mjn> Then wired it all to the feed-thru panel...
[03:59:19] <wb9mjn> Need a bigger Z servo motor...it gets a little warm...
[03:59:23] <wb9mjn> Z and Y are fine...
[03:59:32] <wb9mjn> X and Y,,,that is...
[03:59:58] <wb9mjn> Then about 1/2 way through the project, Abdul came out withthe MotenC-100...so went with that...
[04:00:09] <wb9mjn> Its been working well...
[04:00:20] <SWPadnos_> heh - you're creeping toward that $20k benchtop here ;)
[04:00:52] <wb9mjn> No..more like $12 K....the mechanicals are bolted together, not cast like in the $20 K machines...
[04:01:10] <wb9mjn> Probably have spent close to $8K...
[04:01:23] <wb9mjn> Half of it being the original purchase...
[04:01:56] <SWPadnos_> including tooling and stuff, or just the machine
[04:02:03] <wb9mjn> Really got zapped by bad description....The original column did have a nice 5/8 ths ball scree though...
[04:02:14] <wb9mjn> Just the machine...
[04:02:45] <wb9mjn> Only tooling I have are a few cutters, a drill chuck, and some R8 collets...
[04:02:51] <SWPadnos_> hm - I think I've got about the same into my Bridgeport, and I'm pretty sure I have all the parts I need (just not the time)
[04:03:31] <wb9mjn> Yea...I noticed if I would have bought something that weighed a ton (litterally) it would have been cheaper !
[04:03:46] <SWPadnos_> heh - all but the delivery (that was a PITA)
[04:03:50] <wb9mjn> This machine only wieghs about 300 pounds...
[04:04:16] <wb9mjn> Including the blue box, and the steel stand with the 8020 reinforcement....
[04:05:20] <wb9mjn> But, its been an adventure, hi...
[04:05:40] <SWPadnos_> that's about what my table weighs
[04:06:26] <wb9mjn> Yep...the tool table wieghs about 30 pounds, and the motion x/y table also about 30 pounds (aluminum)...
[04:06:53] <wb9mjn> The column is cast iron about 50 pounds, and the foot is steel also about 50 pounds...
[04:07:46] <SWPadnos_> I think my X ballscrew is around 50 pounds
[04:08:00] <SWPadnos_> hm - maybe 35
[04:08:28] <wb9mjn> All three ballscrews are on the machine are 5/8 ths...with double nuts...
[04:09:03] <SWPadnos_> that should be plenty for that length
[04:09:53] <wb9mjn> At least I got the 6 inch Y travel...and enough Z to play with .... only the X was under the goal I wanted...
[04:10:20] <SWPadnos_> AHA!! I think I found the stupid following error problem
[04:10:49] <wb9mjn> Have some more gaurding to do and I m reworking the X table limits so they do not stick out as far...
[04:11:41] <wb9mjn> If somebody can get one of these DM 6 s for under 1.5 K, its good hobby rebuild project...So far tht s my opinion..
[04:12:28] <wb9mjn> But for $4 to 6 K one should be able to get better (brigeman XT ?) ...
[04:13:04] <SWPadnos_> woohoo - 180 IPM rapids!!! no following errors in G0 mode!!!
[04:13:15] <wb9mjn> What was the problem ?
[04:13:16] <SWPadnos_> (no machine attached, of course)
[04:13:22] <wb9mjn> Oh...
[04:13:25] <Jymmm> SWPadnos: Now, turn on the power supply to the drivers.
[04:13:29] <SWPadnos_> the stupid PID blocks had their output limited to 1
[04:13:54] <SWPadnos_> I changed that to [AXIS_n]MAX_VELOCITY
[04:13:58] <Jymmm> * Jymmm actually can get 100IPM
[04:14:03] <Jymmm> 180 IPM
[04:14:18] <Jymmm> hell, I can get 200 IPM
[04:14:22] <SWPadnos_> I'll be able to get 170 if I want, but I thikn that wouldn't be the greatest on a Bridgeport
[04:14:24] <wb9mjn> Want to see a picture of my 240 ipm machine lymm ?
[04:14:37] <Jymmm> wb9mjn sure, why the fuck not
[04:14:39] <SWPadnos_> if I switch to Rutex drives, I'd be able to go *really* fast
[04:14:41] <wb9mjn> Its smaller than a brigeport...
[04:14:45] <Jymmm> * Jymmm hates fucking computers - damn POS
[04:14:55] <Jymmm> all of em
[04:15:23] <Jymmm> wb9mjn url?
[04:15:37] <wb9mjn> I m trying to DCC to u...not working....
[04:15:40] <wb9mjn> Or is it ?
[04:15:43] <Jymmm> can't dcc
[04:15:46] <wb9mjn> Ok...
[04:16:27] <wb9mjn> Its a D and M 6...vocational ed machine from the 70 s...rebuilt it with servos, and a new X/Y linear bearing table..
[04:16:43] <Jymmm> wb9mjn go get an acnt on flickr.com
[04:16:59] <Jymmm> wb9mjn if you already have a yahoo acnt, you can just login
[04:17:18] <wb9mjn> Not tonite...time for me to go to bed...
[04:17:34] <wb9mjn> But another day...spent allot of time today figuring out DCC through DSL !
[04:18:27] <wb9mjn> I like the idea of the servo loop going through the computer SWPadnos...makes it easier to work on...
[04:20:12] <wb9mjn> That s why I chose the MotenC-100 when it came out over the Rutex...
[04:20:32] <SWPadnos_> emc is the only control software (available to hobbyists) I know of that does that
[04:21:01] <SWPadnos_> all the other stuff, including everything for Windows, is open loop - even if it's using servos and encoders
[04:21:03] <wb9mjn> Do you need features not in EMC ?
[04:21:23] <SWPadnos_> there are some convenience features in DeskCNC and Mach
[04:21:38] <SWPadnos_> things like loading an image, and being to engrave it
[04:21:53] <SWPadnos_> that can be done on emc, but it's several "manual" steps
[04:22:11] <wb9mjn> There is software to convert images into 3d engrave G codes, no ?
[04:22:29] <SWPadnos_> yes, but not "integrated" - no big deal for me, but less convenient
[04:23:03] <SWPadnos_> also, DeskCNC comes with a STL-> G-code converter
[04:23:04] <wb9mjn> Anyway...time for bed...night all...
[04:23:17] <SWPadnos_> load up a model, select some machining methods, and start cutting
[04:23:21] <SWPadnos_> night
[04:40:06] <CIA-5> 03paul_c * 10emc2-auto/wiki/ (30 files in 20 dirs): "Auto update wiki from a cron job. Thu Dec 1 05:30:01 GMT 2005 "
[04:47:35] <CIA-5> 03swpadnos * 10emc2/configs/ (ppmc_io.hal ppmc_motion.hal): Changed a bunch of parameters to be loaded from appropriate [AXIS_n] sections of emc.ini. Added some comments on how to use the PPMC hal files.
[11:33:12] <wb9mjn> Anybody awake ?
[11:33:25] <alex_joni> * alex_joni is barely awake
[11:33:53] <wb9mjn> Morning Alex_joni....I m actually an hour late waking up...on vacation...
[11:34:12] <wb9mjn> Aren t you in Europe ?
[11:37:16] <alex_joni> I am..
[11:37:27] <alex_joni> it's 14:30 over here, but I am kinda sick
[11:37:33] <alex_joni> so not fully awake :(
[11:38:03] <wb9mjn> Sorry to hear that....I get a flu shot each year...but even so, had the flu last spring...
[11:38:15] <wb9mjn> Its 06:30 here....
[11:39:00] <wb9mjn> Figured out how to do DCC here...so can send pictures now !
[11:39:45] <alex_joni> what kind of pictures ? :)
[11:40:25] <wb9mjn> I have a picture of the Ydrive on my machine, and the machine itself....which is no longer a virgin, it cut metal
[11:40:31] <wb9mjn> for the first time last night!
[11:41:25] <alex_joni> great
[11:41:33] <alex_joni> put some on frappr ;)
[11:41:39] <wb9mjn> Can you recieve DCC pictures ? Want to see them ?
[11:41:42] <alex_joni> sure
[11:41:51] <alex_joni> http://www.frappr.com/emctheenhancedmachinecontroller
[11:42:23] <wb9mjn> Not really done far enough for Frapper yet...
[11:42:33] <wb9mjn> Getting there....
[11:42:43] <alex_joni> ok ;) dcc them over
[11:43:16] <wb9mjn> Here comes the Ydrive...
[11:43:53] <alex_joni> nice
[11:44:41] <wb9mjn> That was the original DandM 6 drive plate for the NEMA 34 on a cheap asian table...I had to flatten it, they used
[11:45:02] <wb9mjn> bar stock which was somewhat convex (bulged out on both sides)...
[11:45:40] <wb9mjn> Luckily, the slot in the bar stock was the same size as the pilot boss on the servo motor...So just had to put in throuh
[11:45:50] <wb9mjn> holes to secure the motor....
[11:46:31] <alex_joni> nice
[11:46:52] <wb9mjn> On the top is the 5K encoder...on a comon shaft as the timing pulley...Made that part from SDP timing pulley bar stock...
[11:47:30] <wb9mjn> Turned down one end to 3/8 ths , and counter bored the other end for the table drive shaft, and left the pulley teeth
[11:47:43] <wb9mjn> in the middle...That was the trickiest part of it...
[11:48:16] <wb9mjn> In the end, the runout on the tip of the shaft was less than .001 ...
[11:48:58] <wb9mjn> To tension the belt, I added the bearing pocket and idler bearing...
[11:49:25] <wb9mjn> Here comes the whole machine...
[11:51:10] <wb9mjn> The recent acquisition was that European (DIN 508) Tslot table..its hardened, and I could not get bolts in from
[11:51:37] <wb9mjn> below...So, I had to have the threaded holes in each corner EDM counter bored, so I could drop in bolts from
[11:51:39] <wb9mjn> above....
[11:51:43] <alex_joni> looks nice
[11:52:15] <wb9mjn> Luckily, found a local small EDM shop whould could do it....West of Ohare Airport there are all sorts of small
[11:52:24] <wb9mjn> machine shop companies....
[11:52:58] <wb9mjn> The Tslots are 12 mm standard...
[11:53:37] <wb9mjn> The X/Y table are linear bearing tables, same size and kind for each...Rather than mount in the usual way,
[11:53:57] <wb9mjn> I bolted the two travellers together to make a saddle...
[11:54:48] <wb9mjn> That was tricky, as it required removing the travellers, then reinstalling them..In order to get them back on I
[11:55:35] <wb9mjn> had to use a piece of tubing to keep the first few bearing balls from poping out due to imperfect hand-fed initial
[11:55:38] <wb9mjn> alignment....
[11:57:03] <wb9mjn> Each table was so close in allignment to its traveller, that the other traveller would not fit....
[11:58:10] <wb9mjn> Anyway...its been a long project...I think I started in fall of 2003 ...
[11:58:16] <alex_joni> probably I'm too sick to get what you're talking about :)
[11:58:23] <alex_joni> but I'm happy for you that it works :P
[11:58:38] <alex_joni> and that you seem happy with it
[11:58:51] <wb9mjn> Oh...the linear bearing tables have a part that moves, the traveller, which is driven by the ball screw...
[11:59:04] <alex_joni> yeah I know..
[11:59:15] <alex_joni> but I'm too dizzy to follow it more than that :)
[11:59:18] <wb9mjn> Normally, these tables are mounted so that the traveller bolts to the table above....
[11:59:42] <alex_joni> don't waste your time trying to explain ;) it's not bad explaining..
[11:59:50] <wb9mjn> But, in normal X/Y milling machine service the two travellers make a saddle...
[11:59:59] <alex_joni> it's just I've got a major headache, and my head is refusing to think ..
[12:00:13] <wb9mjn> between the Y table, and the X table...ok...
[12:00:52] <wb9mjn> Anyway, the original machine was all NEMA 34 steppers with R/L single step drives...I tore that all out and
[12:01:16] <wb9mjn> replaced it with a servo system...Using Abdul's MotenC-100...
[12:02:14] <wb9mjn> The R/L drive had a 2 foot by 6 inch heat sink ! The Gallil servo amps only need to be bolted to the panel for
[12:02:19] <wb9mjn> heat sinking....
[12:05:48] <wb9mjn> Anyway...let you go get some recuperation there.....
[12:18:07] <les_w> morning!
[12:19:30] <cradek> sure is
[12:19:36] <cradek> and an early one at that
[12:19:44] <cradek> I mean, hi
[12:19:48] <les_w> haha
[12:22:53] <wb9mjn> Hi Les...want to see some pictures ?
[12:23:17] <wb9mjn> Running mIRC now, and have my firewall set to let DCC through...
[12:23:30] <wb9mjn> Snowing here...
[12:23:42] <wb9mjn> good day to make limit switch brackets...hi..
[12:24:22] <les_w> yeah. Snowing huh? may have to be up your way in a bit. the tools works have summoned.
[12:25:30] <les_w> Corp headquarters is in glenview, but I would prob stay in Schaumburg near where I lived
[12:26:35] <wb9mjn> Are you getting that DCC request ?
[12:26:47] <les_w> no
[12:26:48] <les_w> hmm
[12:27:01] <les_w> hang on
[12:27:28] <wb9mjn> Hmm...oh well...Its been working with several other guys on here...
[12:28:00] <les_w> I may have a problem on this end since I replaced the router
[12:28:11] <wb9mjn> Ok...
[12:28:44] <wb9mjn> Mirc has a way of finding out the real IP address and using it...
[12:29:03] <les_w> i'm using that
[12:29:30] <wb9mjn> Think the problem is there, now...supprised you did not at least get the request as previously..
[12:30:07] <wb9mjn> Anyway...it cut metal for the first time last night...
[12:30:15] <wb9mjn> Try to send me something les...
[12:30:21] <les_w> k
[12:31:55] <wb9mjn> skunk, want to see some pictures of my machine ?
[12:32:00] <skunkworks> sure
[12:32:40] <skunkworks> I may not have ports open in my router - what would I need open?
[12:33:01] <wb9mjn> I accepted your send request Les...
[12:33:11] <les_w> k
[12:33:47] <wb9mjn> Connection failed less...Looks like the problem is in the me to you direction...
[12:34:02] <wb9mjn> 1024 to 5000 is what they recommend skunkworks..
[12:34:10] <les_w> yeah. checking some things here
[12:34:27] <skunkworks> wow
[12:34:29] <skunkworks> hold oin
[12:34:30] <skunkworks> on
[12:34:59] <wb9mjn> What is your internet connection there skunkworks ?
[12:35:13] <skunkworks> cable
[12:35:53] <wb9mjn> Ok...welp, i m on DSL, and had to switch to mIRC for DCC to work...it has the capability of ferreting out the
[12:35:59] <skunkworks> those ports should be open to my machine now - anything I need to do to mirc?
[12:36:05] <wb9mjn> real IP address....
[12:36:23] <les_w> my mirc found mine ok
[12:36:28] <les_w> just checked
[12:36:28] <wb9mjn> Ok...mIRC was defaulted in the way it needed to be...here goes...
[12:36:34] <les_w> everything looks fine
[12:37:22] <wb9mjn> trying you again Les....
[12:38:25] <wb9mjn> I m not familiar how cable does the IP translation....
[12:39:03] <wb9mjn> Skunk timed out,,,trying it again...
[12:39:13] <les_w> nothing here yet
[12:39:25] <wb9mjn> Les timed out...resending...
[12:40:03] <wb9mjn> Wierd...oh well....
[12:40:52] <wb9mjn> Cradek, alex_joni, SWPadnos_ and lymm all got these pictures...
[12:40:57] <wb9mjn> ok...
[12:41:11] <skunkworks> oh sure - blame it on us ;)
[12:41:17] <wb9mjn> LOL...
[12:42:50] <wb9mjn> Anyway...
[12:43:16] <les_w> starange
[12:43:22] <les_w> dtrange
[12:43:24] <wb9mjn> There are lots of web resources out there to figure out DCC...just do a google skunk...
[12:43:27] <les_w> grr
[12:43:40] <skunkworks> les - let me try to send you a picture
[12:43:45] <les_w> time for a new keyboard...or glasses
[12:43:49] <les_w> k skunk
[12:44:07] <wb9mjn> skunk, try to send me one too..sometimes the problem is unidirectional...
[12:45:11] <wb9mjn> Apparently, identd protocoll needs to work too...as well as the ports for DCC...
[12:48:25] <wb9mjn> Nothing happening on this end...
[12:48:56] <les_w> I had dcc server unchecked
[12:49:04] <les_w> trying to send
[12:49:43] <wb9mjn> Got the request Les...
[12:50:19] <wb9mjn> It bombed out...lost connection...
[12:51:42] <les_w> timed out
[12:51:49] <les_w> i'm googling this
[12:57:27] <skunkworks> tried to send wb9mjn a picture
[12:57:57] <les_w> going to restart here
[12:58:47] <skunkworks> wb9mjn - could you try to send me a picture one last time
[12:59:06] <rayh-away> rayh-away is now known as rayh
[13:00:42] <les_w> was reading up on the mirc site...it says dcc problems are usually caused by the sender
[13:00:47] <les_w> trying some stuff
[13:02:05] <les_w> the send request is done on the normal irc channel....that's why we see the request box
[13:02:31] <alex_joni> morning rayh
[13:02:35] <les_w> but if it cannot find both ip addresses or one is wrong it times out
[13:03:09] <Jacky^> hi
[13:03:17] <les_w> hi jacky
[13:03:27] <Jacky^> this coulb be an issue for who use ipv6, maybe..
[13:03:45] <Jacky^> ipv4 should work
[13:04:06] <rayh> Hi Alex
[13:04:11] <les_w> what we don't have is someone that has a dcc system known to work
[13:04:30] <les_w> so we can find who has the problem
[13:05:08] <Jacky^> i think who use a tunnel broker could have some issue
[13:05:20] <les_w> http://www.mirc.com/faq6.html#section6-9
[13:05:46] <Jacky^> anyone know ports used for dcc ?
[13:06:02] <wb9mjn> Hi Jacky...1024 to 5000 ...
[13:06:12] <Jacky^> tcp ?
[13:06:16] <wb9mjn> Attempting a send skunkworks...
[13:06:16] <Jacky^> only ?
[13:06:24] <wb9mjn> Yes jacky...I think so...
[13:06:30] <Jacky^> well..
[13:06:50] <Jacky^> going to portfoward these ports on my internal pc ..
[13:06:51] <wb9mjn> There may be ports needed for identd, but I did not have to open them here...
[13:07:42] <wb9mjn> Morning Ray..want to see some pictures ?
[13:09:12] <rayh> You bet but remember my dialup is s l o w.
[13:09:22] <wb9mjn> Ok..send you the small one first...
[13:09:25] <rayh> I do need to test getting dcc past my firewall.
[13:10:15] <wb9mjn> Did you get the request ray ?
[13:11:23] <Jacky^> les_w: try to take this file from me
[13:11:31] <les_w> ok jacky
[13:11:41] <wb9mjn> Timed out ray..
[13:11:57] <rayh> I never even saw the offer.
[13:12:05] <Jacky^> 15:04 DCC SEND request sent to les_w: tux.jpeg
[13:12:15] <wb9mjn> Ok..probably the firewall zapped it...
[13:12:19] <rayh> I did see offers from swp yesterday
[13:12:21] <les_w> hit my ingnore list jacky
[13:12:26] <les_w> let me fix that
[13:12:32] <wb9mjn> hmm...
[13:12:36] <Jacky^> ok
[13:13:00] <Jacky^> of course we are all registered to the server I suppose
[13:14:42] <les_w> I am
[13:14:47] <wb9mjn> you have a point there...Do not remember setting the password into mIRC..but it worked last night...
[13:14:59] <les_w> hmm I am set to accept *.jpg
[13:15:10] <Jacky^> ok ..
[13:15:15] <les_w> your file was .jpg jacky?
[13:15:31] <Jacky^> jpeg, but ive jpg also
[13:15:35] <Jacky^> wait a sec
[13:15:43] <les_w> ah
[13:15:54] <les_w> try the .jpg
[13:16:30] <Jacky^> les_w: ok
[13:16:35] <Jacky^> it work
[13:16:44] <Jacky^> try to send one to me
[13:16:51] <les_w> perfect...no problem
[13:16:54] <les_w> ok
[13:19:17] <rayh> wb9mjn: I don't see the note "is identified to services"
[13:19:20] <rayh> for you
[13:19:42] <les_w> timed out jacky
[13:19:45] <wb9mjn> Might be the problem this morning...
[13:19:53] <wb9mjn> Looking into it...ray...
[13:19:59] <Jacky^> les_w: strange ive not received any request
[13:20:12] <les_w> very strange
[13:20:24] <les_w> others are getting the request
[13:20:31] <les_w> that I send
[13:20:38] <wb9mjn> The other software logged in automatically...this software is not set up right, or does not automattically login..
[13:20:47] <Jacky^> actualy ive 1024 to 5000 tcp ports forwarded to my local IP
[13:21:13] <Jacky^> wb9mjn: could you please try to send a file to me ?
[13:22:06] <wb9mjn> Im logging out and back in...will try then...
[13:22:29] <wb9mjn> Ok, Im back now...
[13:22:34] <wb9mjn> Here goes...
[13:22:57] <wb9mjn> Requesting...
[13:23:28] <Jacky^> nothing
[13:23:33] <les_w> ah
[13:23:39] <les_w> so I might be ok
[13:23:40] <wb9mjn> Tried all three of you there...
[13:23:45] <Jacky^> les_w: yes
[13:23:59] <wb9mjn> But nothing happening so far but the request...
[13:24:22] <Jacky^> looking at irssi config ..
[13:24:35] <Jacky^> Ive autoaccept dcc = false
[13:24:35] <les_w> send to me again wb9
[13:25:01] <Jacky^> but i should be able to manually accept using /dcc get nickname ..
[13:25:09] <les_w> right
[13:25:16] <wb9mjn> There you go Les...
[13:26:03] <les_w> arg nothing....no accept request....but jacky's was fine
[13:26:08] <les_w> blah
[13:26:19] <wb9mjn> Still had a problem with the password...
[13:26:21] <alex_joni> why don't you guys use e-mail?
[13:26:24] <wb9mjn> Will try again...
[13:26:26] <les_w> heh
[13:26:58] <les_w> yay
[13:27:06] <wb9mjn> Les's file got throug...
[13:27:25] <wb9mjn> SRI about that...new software is wierd, and has poor help file...
[13:27:56] <wb9mjn> That is the Y drive Les...here comes the whole machine..
[13:28:41] <rayh> wb9mjn: connection refused. I am seeing the offer though.
[13:28:46] <les_w> other way now
[13:29:03] <wb9mjn> The trick to the Y drive was making a custom pulley with the shaft for the encoder and a counter bore for the table
[13:29:28] <wb9mjn> drive, all in one piece...from SDP timing belt pulley bar stock...You can see the tip of the part
[13:29:31] <les_w> what kind of mill is that?
[13:29:50] <wb9mjn> coming out of the encoder....down inside it has pulley teeth...
[13:30:18] <wb9mjn> It is a 1970's vocational ed machine...with allot of rework...hi..
[13:30:29] <wb9mjn> Called a DandM 6 ...
[13:30:39] <les_w> originally cnc?
[13:31:02] <wb9mjn> Yes...but a very crappy implimentation...Nema34 steppers, R/L drive...
[13:31:37] <les_w> send timed out.
[13:31:40] <wb9mjn> Very poor X/Y table and mounting to it...The bar in the Y drive was originally screwed to the Y axis with two 1/4x20 cap screws...
[13:31:49] <wb9mjn> spaced about 1 inch appart...
[13:31:51] <les_w> heh
[13:32:10] <Jacky^> 15:24 DCC aborted receiving file Ydrive.jpg from wb9mjn
[13:32:13] <Jacky^> ouch
[13:32:23] <wb9mjn> And it was convex by 1/8 an inch...So, i face milled it, so it would fit flat on the linear bearing table end cap..
[13:32:24] <Jacky^> websys: can retry ?
[13:32:31] <Jacky^> ops wb9mjn
[13:32:43] <wb9mjn> I did a few times Jacky...want me to start again ?
[13:32:52] <Jacky^> damn tab completation ;P
[13:33:05] <Jacky^> wb9mjn: yes, if you can
[13:33:21] <wb9mjn> The servo motor pilot fit in the original belt slot....
[13:33:49] <Jacky^> ok ok, work
[13:33:56] <wb9mjn> So, just screwed it on...used timing belt bar stock for the top pulley, the same size as the original pulley...
[13:33:57] <Jacky^> the prob is another.. 15:26 DCC can't create file /home/james/.irssi/dcc/Ydrive.jpg: No such
[13:34:00] <Jacky^> file or directory
[13:34:24] <Jacky^> ive not created that dir :)
[13:34:42] <wb9mjn> Needed to add the idler bearing, as the belt would skip...
[13:35:09] <wb9mjn> The encoder is 5000 line, or 20000 steps, directly connected to the table drive screw...
[13:35:55] <les_w> screw pitch?
[13:36:14] <wb9mjn> All screws are .2 inch pitch double nut 5/8 inch diameter ...
[13:36:52] <les_w> that is 10 times the encoder resolution I am using
[13:36:54] <wb9mjn> The X and Y work well...need to do some work on the Z to get the encoder in the screw shaft, counter balance the wieght and
[13:37:06] <wb9mjn> maybe a bigger motor...
[13:37:50] <les_w> I just use a bias voltage rather than counterbalance on z
[13:38:03] <wb9mjn> The motor runs too hot for that....
[13:38:14] <les_w> when the machine is off the servo is shorted...that plus friction keeps it from falling
[13:38:22] <wb9mjn> So, either counter balance, or get a bigger motor...haven't decided yet...
[13:38:42] <wb9mjn> It has a brake for falling...it needs it on occaision too...
[13:38:59] <les_w> tiny amount of bias current
[13:39:03] <les_w> 100 ma or so
[13:39:47] <rayh> ah I can send to wb9mjn
[13:39:53] <wb9mjn> Because of the friction, it does not quite make it to nominal..and the current will ramp up..
[13:39:55] <wb9mjn> Yep...
[13:40:18] <wb9mjn> Got some relay ladder logic here...
[13:41:02] <les_w> so this is step-servo?
[13:41:06] <les_w> geckos?
[13:41:09] <rayh> I can receive from wb9mjn
[13:41:22] <wb9mjn> All servos, with MotenC-100 / EMC implimentation...
[13:41:33] <les_w> ray let me try a send to you
[13:42:17] <Jacky^> 15:34 DCC received file Ydrive.jpg [89kB] from wb9mjn in 00:00:06
[13:42:18] <Jacky^> [14.75kB/s]
[13:42:23] <Jacky^> good :)
[13:42:26] <wb9mjn> Uses Galil amps...48 v, 10 amps, motors are 36 volt, amps regulate down by gain setting...
[13:42:36] <les_w> full servo...cool
[13:42:39] <les_w> emc?
[13:42:43] <les_w> must be
[13:43:00] <wb9mjn> Yep...
[13:43:13] <les_w> What box are you using? And what is your servo update period?
[13:43:31] <alex_joni> and what emc ;)
[13:43:34] <wb9mjn> servo update period is 1 ms...with each axis set to a quarter ms...
[13:43:44] <wb9mjn> Using RC_46....
[13:43:52] <alex_joni> ok
[13:44:07] <wb9mjn> Oops...Ray really does have a slow wire...
[13:44:27] <wb9mjn> The PC is a 700 MHz Pentium...
[13:44:57] <rayh> Yup! And the wires are cold today.
[13:45:11] <les_w> have you tried to see how fast you can update the servos?
[13:45:23] <wb9mjn> That makes those electrons flow fast Ray...metal has less resistance when its colder...
[13:45:26] <alex_joni> wb9mjn: what servo card are you using?
[13:45:39] <Jacky^> well no need to portforward any port then , I portforward 1024-5000 but dcc used port 57666
[13:45:45] <wb9mjn> MotenC-100, which is a PCI card, its working well...
[13:45:53] <alex_joni> wb9mjn: nice
[13:46:00] <rayh> I switched my firestarter to permissive on outgoing. That seemed to do the job.
[13:46:38] <wb9mjn> Abdul had is introductory pricing just about the time I was deciding if I was going to do a Rutex or EMC servo ..
[13:49:21] <wb9mjn> The X table also has a custom pulley/encoder shaft on it...in the direction away from the picture view..
[13:50:22] <wb9mjn> The encoders have the flex mounting...so, no shaft coupler needed..the custom puleys are accurate within .001 ... thanks to the
[13:50:33] <wb9mjn> schaublin lathe I did them on...
[13:51:09] <les_w> so CYCLE_TIME is set to .00025 for each axis?
[13:51:23] <wb9mjn> There is one shaft coupler between the X motor and and screw...also made custom mounting NEMA 23 adapters for the
[13:51:25] <wb9mjn> motors...
[13:51:33] <wb9mjn> That s right Les...
[13:52:13] <les_w> tried any faster? when does it lock up/go nuts?
[13:52:17] <wb9mjn> This machine does not have allot of momentum...and PC is handling that speed...talked to a ham guy who works
[13:52:47] <wb9mjn> for Bosch/Rexroth/whichever company they bought this week, who is local..and he said the whole machine should have
[13:53:05] <wb9mjn> less than a msec sampling for the 3D ...
[13:53:52] <wb9mjn> Nope...it does go nuts about 1 in 20 times when it jumps doing a home...
[13:53:56] <rayh> wb9mjn: You need a small bag of blue swarf to throw on that bed before pics.
[13:54:00] <les_w> I think the axis cycle times are non cumulative. If all are set to .00025 the whole 3 axes are done in that time
[13:54:04] <les_w> I think...
[13:54:12] <rayh> I always carry one for shows.
[13:54:22] <wb9mjn> The galil amps do not shut off as cleanly as I would like when a limit is hit, and jump again when its released..
[13:54:53] <wb9mjn> The .00025 is so I can do a rotary axis eventually...
[13:55:17] <rayh> The jump on powerup may be a command from EMC. If the shutdown rolled past commanded.
[13:55:25] <les_w> Need data on servo rates with other than an stg card
[13:55:29] <wb9mjn> LOL, Ray...it actually has some aluminum swarf on it this morning...
[13:55:59] <wb9mjn> To do the home, i run the axis into the limit, reset, then hit home....
[13:56:21] <les_w> no index pulse?
[13:56:29] <wb9mjn> The problem is limit related...I do not have the limits wired into EMC, just the amps...If I push a limit when the axis is
[13:56:40] <wb9mjn> stationary and in the middle of its travel, it will jump...
[13:56:46] <wb9mjn> about .1 inches...
[13:57:00] <wb9mjn> Yes, all the axiis have indexes...
[13:57:24] <wb9mjn> To hit the same index each time, i start from the limit stop...
[13:57:38] <rayh> Does the limit kill power to the amp or do they have limit inputs?
[13:57:45] <les_w> I use a separate home switch that enables index detection
[13:57:53] <wb9mjn> It homes on the index, reversing off the limit...The amps have limit inputs...
[13:58:17] <wb9mjn> The Estop kills power to the amps, though...
[13:58:49] <les_w> yeah, my home switch is about 0.1 in before the limit switch
[13:58:59] <les_w> works great
[13:59:28] <wb9mjn> Wanted to bounce off the limits automatically, and find the index, but the jump makes that problematic...

[14:00:01] <Jacky^> :P
[14:00:05] <wb9mjn> EMC2 ...
[14:00:07] <les_w> hmm well if you can bounce the switch...it isn't really a hard limit?
[14:00:41] <Jacky^> may mirc dont show ascii art good at all
[14:00:58] <wb9mjn> The motor jumps when the limit is hit...then stops...Yea, and on occaision, it will oscillate..but that is rare..
[14:01:04] <les_w> heh...yeah. What is it?
[14:01:45] <wb9mjn> It says EMC2...
[14:01:50] <Jacky^> yeah
[14:02:04] <les_w> For industrial stuff the limit switches have to be wired to the separate estop. Computer is not involved.

[14:02:25] <Jacky^> :)
[14:02:40] <les_w> haha
[14:02:43] <Jacky^> correct showing depend on client I think
[14:03:04] <wb9mjn> Computer is not involved in this...just amps and limit switches...But not an estop...
[14:04:01] <wb9mjn> I think Galil did that to put some counter torque into the motors to help brake the axis when the limit is hit..
[14:04:13] <les_w> yeah. A little different here. Limit switch disables the amps, disconnects and shorts the servos thru a 10 ohm resistor
[14:04:16] <wb9mjn> but my machine is so small it actually reverses the axis...
[14:05:01] <wb9mjn> Yep, I remember Les...do not have a 500 lbs travelling down the ways here...
[14:05:09] <les_w> heh
[14:05:19] <les_w> neither do I.
[14:05:27] <les_w> I have 1000!
[14:05:29] <les_w> haha
[14:05:33] <wb9mjn> LOL...
[14:09:51] <wb9mjn> Time to get some stuff done here....going into standbye...
[14:10:04] <les_w> yeah me too
[14:10:08] <les_w> later
[14:10:33] <Jacky^> les_w: later
[14:11:21] <Jacky^> bye wb9mjn
[14:42:54] <Jacky^> One day Ima go to New York to a bigga hotel. I go down to eat some breakfast. I tella the waitress I wanna two piss toast. She branga me only wona piss. I tella her I wanna two piss, she say go to the toilet. I say you no understand, I wanna two piss on my plate. She say you better not piss on the plate you sonna ma bitch! I don't even know the lady and she calla me sonna ma bitch. Later, I go to eat soma lunch at Emma's Restaurant, the waitress
[14:43:08] <Jacky^> ma lol
[14:46:37] <wb9mjn> Oops...just ignore me...
[15:05:05] <rayh> going to reboot for a test.
[15:34:01] <Jacky^> leodict translates via dict.leo.org
[15:34:09] <Jacky^> this could be a nice script
[16:33:46] <CIA-5> 03swpadnos * 10emc2/configs/core_servo.hal: Changed PID limits to be [AXIS_n]MAX_VELOCITY, and Pgain to 100 - this should fix many of the following errors people were getting with jogs / g0 in emc2.
[16:35:04] <skunkworks> Sweet
[16:35:16] <skunkworks> That is what I was looking for
[16:35:38] <SWPadnos_> it may not help, but then again it might ;)
[16:35:44] <SWPadnos_> are you using core_servo?

[17:04:14] <alex_joni> that's a NICE error message :D
[17:04:16] <ValarQ> :)
[17:04:20] <jepler> try "merkin"?
[17:04:33] <Jacky^> it was loaded .. uhm
[17:04:42] <jepler> or is it spelled "'merkin"?
[17:04:51] <cradek> that's the british spelling
[17:05:32] <Jacky^> uhmm i think under all, some key is needed..
[17:05:39] <Jacky^> like for google api
[17:06:54] <Jacky^> jepler: im testing some script http://scripts.irssi.org/
[17:07:14] <Jacky^> found someone very funny :P

[17:59:52] <alex_joni> hey anders, long time no see
[18:00:04] <alex_joni> in the mean time there's a ppmc driver for HAL ;)
[18:57:59] <Imperator_> Hi all
[18:58:15] <Jymmm> hola Imperator_
[18:58:33] <Imperator_> Hi Jymmm, whats up ?
[18:58:53] <Jymmm> Imperator_: Nada, just working on some designs.
[18:59:06] <alex_joni> hello
[18:59:11] <Imperator_> same here :-)
[18:59:14] <alex_joni> how's the mesa?
[19:01:06] <Imperator_> Hi Alex
[19:01:32] <Imperator_> i study the FPGA beginners tutorial on the Xilinx side at teh moment
[19:01:40] <alex_joni> nice ;)
[19:02:02] <Imperator_> counter is running
[19:02:09] <alex_joni> nice
[19:02:11] <Imperator_> and PWM stuff removed
[19:03:26] <Imperator_> maybe on the weekend i can test my 840D
[19:08:54] <etla> imperator: you are modifying the mesa code ?
[19:19:33] <Imperator_> etla: yes
[19:19:46] <etla> how fae have you got ?
[19:19:49] <etla> far
[19:20:08] <Imperator_> encoders are working now
[19:20:24] <etla> are you writing completely from scratch or based on the mesa code ?
[19:20:28] <Imperator_> that was not that difficult, because i had only to change the pinout
[19:20:38] <Imperator_> based on mesa code
[19:21:04] <Imperator_> i removed PWM and changed the counter pins
[19:21:30] <etla> you want the torque command as 16-bit parallell for your DACs ?
[19:21:45] <Imperator_> yes
[19:21:58] <Imperator_> torque or velosity
[19:22:23] <Imperator_> for teh first velosity, the rest is done by the amp
[19:22:26] <Imperator_> the
[19:22:35] <etla> does the dac then just have a 16-bit mux for the different axes ?
[19:22:49] <Imperator_> yes
[19:23:00] <etla> so you need 2-3 bits for the mux also
[19:23:01] <Imperator_> two adress lines and 16 bit data
[19:23:17] <Imperator_> DAC7744
[19:23:20] <etla> only 4-axis machining then...
[19:23:42] <Imperator_> enough
[19:23:57] <Imperator_> but our hardware can expanded to 8
[19:24:26] <Imperator_> on the counter board, there are six inputs at the moment
[19:24:46] <Imperator_> but i think i remove the two optional inputs
[19:25:03] <Imperator_> we are using that lines for the limit and ref switches
[19:25:09] <etla> you have rs422 decoder on the counter board ?
[19:25:44] <Imperator_> 26ls32
[19:26:28] <etla> did you make your own optoisolator board also or are you using the mesa optoisolatorboard for I/O ?
[19:27:23] <Imperator_> we have a 16 Input and 8 output board
[19:28:44] <Imperator_> it is at the moment directly wired to one of the 50pin connectors. we want to use there a bus, so that you can use many of that io boards
[19:29:22] <etla> yep, sounds good, again data+address format.
[19:29:29] <Imperator_> http://www.peters-cnc-ecke.de/forumupload/uploadFiles/3686_115677871897_16i8o.jpg
[19:29:37] <Imperator_> is that link working ?
[19:29:56] <etla> yes
[19:30:15] <etla> thats the I/O card ?
[19:30:56] <Imperator_> thats the io board, but the Phoenix connectors are missing on that picture

[19:32:22] <etla> nice work. do you work at a university or school where you can do this ?
[19:32:59] <rcsu> really nice photos :)
[19:33:05] <Imperator_> have worked in a university up to this summer
[19:33:18] <Imperator_> but that is done at home
[19:33:32] <Imperator_> rcsu: thx
[19:33:48] <etla> do you have pics of the ad board and counter board also ?
[19:33:57] <rcsu> ideal to place it into a web shop
[19:34:05] <Imperator_> :-)
[19:34:22] <alex_joni> that picture screams EBAY all over
[19:34:58] <Imperator_> on the picture with al that components, that are two boards, they are cutted now so that are four
[19:35:39] <Imperator_> too expensive for ebay
[19:36:06] <rcsu> that only depends on your source for the material
[19:36:13] <etla> I hope you are going to publish the plans !
[19:36:28] <Imperator_> when it is working
[19:37:20] <rcsu> no one sees them for review ?
[19:38:12] <rayh> Nice looking stuff martin.
[19:38:26] <Imperator_> Hi rayh, thaks
[19:38:38] <Imperator_> have bought components for 400 EUR
[19:39:02] <etla> are you making 20 boards ? :)
[19:39:55] <Imperator_> not enough for 20 Boards, the DAC is 50 EUR by itself
[19:40:25] <etla> oh, sorry I did not realize that. sounds a bit pricey, much cheaper in volume I guess
[19:40:55] <Imperator_> maybe, but we want real industrial quality
[19:41:33] <Imperator_> if it is running well, then we have to think on how to test it !!
[19:41:33] <etla> what machine(s) are you planning on driving ?
[19:42:14] <Imperator_> something special
[19:42:38] <Imperator_> with a polymer concret frame
[19:42:38] <etla> test the whole thing or just boards separately ?
[19:42:52] <Imperator_> just the boards
[19:42:55] <etla> heh, DIY VMC
[19:43:09] <Imperator_> ?
[19:43:10] <rcsu> ?
[19:43:47] <etla> poly concrete frame cnc machine, or what were you saying ?
[19:45:42] <Imperator_> jep
[19:46:18] <wb9mjn> Poly concrete has better dampening characteristics than even cast iron...

[19:47:10] <Imperator_> http://www.peters-cnc-ecke.de/forumupload/uploadFiles/1298_110779439075_IMG_1668.JPG
[19:47:23] <rcsu> bah
[19:47:26] <Imperator_> http://www.peters-cnc-ecke.de/forumupload/uploadFiles/1298_110779439075_IMG_1695.JPG
[19:47:53] <wb9mjn> Do they use iron rich granite for the agregate, like on railroad tracks ?
[19:47:58] <Imperator_> with a bit colour:
[19:48:02] <Imperator_> http://www.peters-cnc-ecke.de/forumupload/uploadFiles/1298_110779439075_IMG_1680.JPG
[19:48:12] <Imperator_> was not enough
[19:48:41] <etla> what epoxy are you using ?
[19:48:46] <wb9mjn> Is that high temp epoxy, to give enough open time to do the large casting ?
[19:48:48] <Imperator_> it is silicat
[19:49:00] <wb9mjn> silicat ?
[19:49:07] <Imperator_> sand
[19:49:17] <wb9mjn> Yes, but what is the matrix ?
[19:50:15] <Imperator_> normal epoxi with a hardener that has 2h open time
[19:50:41] <wb9mjn> Ok...looks red like West Systems stuff...
[19:50:59] <Imperator_> dont know the real english names for that stuff
[19:51:00] <etla> how do you think the thermal properties will scale to something bigger ??
[19:52:14] <Imperator_> i dont whink that i will get some thermal problems, because there are only 8% epoxi in there
[19:52:22] <Imperator_> think
[19:52:58] <etla> so you are actually going to build a machine from scratch using this stuff ??
[19:53:28] <Imperator_> im busy with the electronic at the moment
[19:55:00] <etla> yah, gotta start somewhere
[19:55:20] <Imperator_> :-)
[19:56:13] <etla> do you have motors and amps already ?
[19:59:35] <Imperator_> Siemens Simodrive, yes
[19:59:51] <Imperator_> and some Alsthom DC Servos
[20:00:32] <Imperator_> Alsthom Parvex servos
[20:01:13] <etla> ok, my latest plan is to use the IR IRMCK201 to build an AC servodrive for the surpluscenter motors
[20:01:53] <Imperator_> thats a heavy thing
[20:02:34] <etla> yeah but using the irmck takes care of the motor control algorithm
[20:02:40] <etla> so I don't have to do it
[20:03:22] <Imperator_> motorcontroler != servocontroler
[20:04:28] <etla> well, the servodrive would accept an analog torque command, use the iramx integrated powerstage, have the current feedback etc.
[20:04:40] <etla> but the most complex things are done in the irmck
[20:05:53] <etla> so hopefully it won't be that hard to get it to work
[20:06:42] <CIA-5> 03alex_joni * 10emc2/tcl/bin/ (8 files): some efforts toemc2ify the tcl bins
[20:20:39] <CIA-5> 03alex_joni * 10emc2/tcl/bin/genedit.tcl: changed that the editor pops up, only when run outside of tkemc, when run from tkemc the proper function gets called anyways

[22:08:24] <Jacky^> come sta male mo
[22:08:26] <Jacky^> ops
[22:45:36] <alex_joni> where is everybody?
[22:45:52] <Jacky^> who ?
[22:47:59] <CIA-5> 03alex_joni * 10emc2/src/emc/iotask/ioControl.cc: fixed a stupid bug I just stumbled upon. a fp was closed that wasn't open
[22:48:04] <alex_joni> everybody..
[22:48:18] <Jacky^> im watching TV
[22:48:48] <Jacky^> a political program :/ not much interesting
