[02:02:19] <DJ9DJ> moin
[07:11:42] <ReadError> i_tarzan has a wonderful connection
[07:15:48] <Loetmichel> ReadError: ... and rockstable ;-)
[07:52:26] <jymmm> I don't get it... how in the hell can aluminum powder be so explosive
[07:54:38] <Loetmichel> jymmm: get some rust mixed in and look in awe at the result ;-)
[07:57:56] <jymmm> Loetmichel: what happens?
[08:05:51] <Spida> *fump*
[08:06:30] <Spida> rust gets more oxygen to the aluminium
[08:06:49] <jymmm> exotheric reaction?
[08:08:29] <Loetmichel> google thermit
[08:09:39] <jymmm> Loetmichel: are you talking rust or iron oxide like in a hand warmer?
[08:10:50] <Loetmichel> milled rust will do
[08:10:54] <Loetmichel> rust powder
[08:11:16] <jymmm> ah, like thr dust produced form turn your brake drums
[08:12:01] <Loetmichel> thats the way nearly all railways welds their rails in place
[08:12:32] <Loetmichel> concrete form around the gap, thermit in, magnesium starter lighted on top, RUN
[08:12:50] <Loetmichel> s/form/mould
[08:13:45] <jymmm> Well, I'm not really looking for an explosive as much as a way to lower the auto-ignition temperature of materials
[08:14:01] <Loetmichel> itas not an explsive
[08:14:20] <Loetmichel> ist more like a oxygen lancet in powder form ;)
[08:14:56] <Loetmichel> VERY hot, sputtering molten steel.
[08:15:26] <archivist> I have some thermit here :)
[08:17:14] <jymmm> archivist: A microwave isn't fast enough to heat your morning coffee/tea?
[08:21:55] <archivist> my thermit has bronze/brass powder in it too, makes a brazed joint
[08:30:28] <jymmm> archivist: Don't like waiting for the soldering iron to heat up either huh?
[08:31:04] <Loetmichel> hrhr
[08:31:04] <archivist> since when has it been possible to braze with a soldering iron!
[08:31:19] <jymmm> it's a joke, eeesh
[08:31:22] <Loetmichel> archivist: with the right soldering iron: since ever ;-)
[08:32:13] <Loetmichel> i have an old one with defective regulation which gets red hot... should be enough for brass ;-)
[08:34:11] <archivist> red is not hot enough needs to be bright red
[08:34:20] <Loetmichel> hmmm
[08:34:28] <Loetmichel> dontz have a thermometer
[08:34:38] <Loetmichel> that cahn indicate more than 1000°c
[08:34:39] <archivist> I have :)
[08:34:55] <Loetmichel> but the one i have goes to blinking 999
[08:35:05] <Loetmichel> SHOULD be enough ;-)
[08:36:24] <Loetmichel> IIRC brass melts a t about 700°c
[08:36:52] <archivist> depends which brass http://www.engineeringtoolbox.com/melting-temperature-metals-d_860.html
[08:36:59] <archivist> 900+
[11:11:41] <archivist> just right for retrofit fleabay 160802140162
[11:18:14] <ReadError> lol
[11:18:16] <ReadError> no link?
[11:19:37] <Aero-Tec> got the lathe fixed
[11:20:30] <Aero-Tec> grounding problems and noise, needed to reroute some wiring
[11:20:33] <archivist> ReadError, you put the number in fleabays search in whichever countries version of fleabay
[11:22:47] <ReadError> 2000 pounds for a replacement eeprom ?
[11:22:51] <ReadError> jeeezeee
[11:23:08] <archivist> cnc users get ripped off
[11:23:48] <archivist> it is 10 miles from me but I dont have cash or space
[11:24:17] <ReadError> do you have the need?
[11:24:53] <archivist> not really, except retrofit and sell as a worker :)
[11:32:36] <Aero-Tec> 2000 for a eprom card
[11:32:48] <Aero-Tec> not just the eprom
[11:33:08] <Aero-Tec> so not as bad, still not good
[11:33:32] <Aero-Tec> you could borrow the money
[11:33:44] <Aero-Tec> fix it and sell for a profit
[11:34:06] <Aero-Tec> throw it under a tarp
[11:34:27] <Aero-Tec> work on it as much as you can and them cash in
[11:34:42] <Aero-Tec> would make a great convert to mach
[11:35:46] <Aero-Tec> looks like you can get it for $1500
[11:36:18] <Aero-Tec> should be able to get it running for 2500
[11:37:03] <Aero-Tec> should be work 10K or so
[11:37:08] <Aero-Tec> oops
[11:37:21] <Aero-Tec> used the mach work in a EMC forum
[11:37:28] <Aero-Tec> shame shame
[11:37:31] <Aero-Tec> lol
[11:38:38] <Aero-Tec> a dash of paint would help the sale along, could make it worth 20K
[11:52:16] <archivist> the m word...wash your mouth out!
[11:53:02] <archivist> it would be cheaper to retrofit probably and it would become a better machine
[12:19:58] <tjb1> Anyone using the CNCrouterparts linear carriages?
[12:22:36] <archivist> there was someone in here couple of weeks back making a machine with them
[12:29:21] <tjb1> Without the racks for my machine, Im at about 2,200 buying everything
[12:29:37] <tjb1> I would like to make the carriages since they are so expensive
[12:32:24] <archivist> what sort of cnc are you making
[12:34:09] <tjb1> plasma table
[12:34:30] <tjb1> I hate that…the draws he provided have dimensions but you can't dimension off the drawing because it has been scaled...
[12:35:22] <archivist> ok so a little play is ok so that would be suitable if you keep dirt off them
[12:36:27] <archivist> last user was intending to run on aluminium track, I think he will have problems
[12:37:05] <tjb1> http://a4.sphotos.ak.fbcdn.net/hphotos-ak-ash4/414905_3554298172111_1112377031_33394573_527938187_o.jpg
[12:37:06] <tjb1> thats mine
[12:37:34] <tjb1> Scaled the drawing and the bearings have a diameter of .8661
[12:38:47] <aj438393> Hi All, could someone tell me if the web registration for the forums are running correctly?
[12:38:56] <tjb1> Ah thats cool, the carriages just use abec 7 skateboard bearings
[12:39:27] <aj438393> Whenever i enter my details i get sent back to the same page with the form blanked and no error message or confirmation
[12:40:04] <tjb1> linuxcnc forums?
[12:40:09] <aj438393> yup
[12:40:24] <archivist> tjb1, if spatter lands on the track it could jamb your carriages have covers if possible
[12:40:46] <archivist> aj438393, use a better bame spammers have numbers in names
[12:40:47] <tjb1> Ill figure that out once I get it built
[12:40:54] <archivist> bame name
[12:41:25] <archivist> aj438393, there is some anti spammer detection probably catching you
[12:41:46] <tjb1> I was able to register
[12:42:06] <aj204> humm, is gmail emails in the banned list?
[12:42:16] <archivist> I dont think so
[12:42:24] <tjb1> archivist: do you think I need more supports for the extrusions or is 4 each enough?
[12:42:34] <aj204> sorry about the rubbish nick, was annoyed at all the hoops needed to get irc running on this machine :S
[12:43:00] <aj204> il go try my luck registering again
[12:43:27] <archivist> tjb1, probably as your carriage load is constant
[12:43:47] <tjb1> They aren't really meant to support the extrusions
[12:43:57] <tjb1> more of just hold them in place and allow shimming to square
[12:45:33] <aj204> meh, giving up on the forum registration for now :S
[12:45:56] <aj204> would this channel be suitable for asking software question about linuxcnc?
[12:46:28] <tjb1> yes
[12:46:43] <tjb1> I don't use it yet so I won't be of much help
[12:48:48] <aj204> Im having a stability problem when running linux cnc, it often crashes with a segfault or general protection fault
[12:49:18] <aj204> i cant find any post mentioning this when searching for segfault or protection fault so its not that common i assume...
[12:49:20] <cradek> what version?
[12:50:06] <aj204> 2.4.7 and 2.5.0 both running on ubuntu 10.4 downloaded from linuxcnc.org
[12:50:40] <aj204> the protection fault blamed python2.6 while the segfault blames Axis
[12:51:52] <aj204> Most of the troubleshooting tips centered arount timming issues, or video issues but unless the video issue :S
[12:52:08] <aj204> causes segfaults i dont think that would help
[12:52:18] <cradek> hmmm... have you tried running memtest?
[12:52:30] <aj204> ram issue?
[12:52:56] <cradek> if stuff is crashy on a certian machine but not others, often it's just bad hardware
[12:53:10] <cradek> memtest is sort of ok at finding hardware problems
[12:53:37] <cradek> I've seen it find bad ram lots of times, and bad cpu cache once
[12:53:49] <aj204> cradek: ok, so unlikely do be video driver problem
[12:54:22] <cradek> I wouldn't rule that out without further data
[12:54:42] <cradek> but do try memtest first
[12:55:25] <aj204> ok, will try that.
[12:55:56] <aj204> thanks for the advice
[13:00:46] <tjb1> I need a better source for bearings
[13:01:01] <tjb1> these skateboard bearings are about $.8 each
[13:01:38] <archivist> cheap enough
[13:02:01] <tjb1> Well I need to buy 48 of them
[13:02:10] <tjb1> They are only 22mx7mm
[13:03:40] <archivist> I know look for sellers on ebay selling packs of 10 like item 120913428909
[13:05:19] <tjb1> What is the ors?
[13:05:22] <tjb1> *2rs
[13:06:58] <archivist> the seal rs is rubber seal " well 2 sides, zz is shielded (less friction)
[13:07:11] <tjb1> Alright, thanks
[13:07:15] <tjb1> Found a 50 pack for $26
[13:08:28] <ReadError> im getting pretty dang good with solidworks+visualmill :)
[13:08:40] <ReadError> well not _good_, but fast
[13:09:05] <tjb1> Any more research on a tig welder ReadError ?
[13:11:02] <jthornton> aww aj left
[13:12:30] <tjb1> Whats it called when you have multiple wires together
[13:12:41] <jthornton> archivist, gmail is highly filtered if allowed at all as 99.97% of spammers use gmail accounts
[13:13:06] <jthornton> cable
[13:16:55] <tjb1> Thanks jthornton found it
[13:32:58] <Aero-Tec> back to the same problem on my lathe
[14:42:03] <frallzor> http://www.multicamnw.com/support/manual/onsrud_routing_guide.pdf seems like nice material if one is interested =)
[14:53:32] <mrsun> archivist, there? :)
[14:53:55] <archivist> hoo meee?
[14:54:07] * frallzor cuddles with archivist
[14:54:14] <frallzor> you better like it
[14:54:15] * archivist runs
[14:54:44] <mrsun> archivist, you had a southbend? .. what size is it? :)
[14:57:34] <mrsun> btw, 6.74mm of a threaded hole, does that match up any good with any metric or imperial threads?
[14:57:45] <mrsun> a set screw is missing on the lathe to guide the quill
[14:58:17] <archivist> a big ish one, cat number 81830 serial 96073 let me go into the garage to see size
[14:58:38] <anonimasu> mrsun: there is m7...
[14:59:12] <mrsun> m7 sounds strange, but its an old lathe so who knows =)
[14:59:30] <mrsun> archivist, was thinking if it was 4 1/2 inch or something so it matched some =)
[14:59:44] <anonimasu> i see them sometimes at work, rarely but they do exist
[14:59:46] <mrsun> and was about a set screw that is on the front of the whats it named, that the quill is sitting in
[15:00:06] <mrsun> right under int he front ... if its an ordenary set screw or something more
[15:00:37] <frallzor> M8 is 6.8mm
[15:00:45] <archivist> mrsun, mine is a 14 1/2 inch swing 6ft bed one
[15:01:03] <mrsun> frallzor, could be then =)
[15:01:04] <anonimasu> frallzor: might well be it
[15:01:24] <anonimasu> alot more likely, try a m8 first..
[15:01:58] <mrsun> is there any imperial that is close to size of an m8 ?
[15:02:07] <frallzor> 5/16
[15:02:10] <mrsun> feels stupid to buy a m8 set screw and then its imperial anyways :P
[15:02:27] <anonimasu> i made some shafts today measured at -0.001mm and -0.002 on a run of 10 of them ^_^
[15:02:29] * frallzor is looking at the back of his vernier caliper
[15:02:34] <frallzor> nice chart
[15:02:49] <archivist> mrsun, mine is similar to http://www.southbendlathe.com/historical_photo.aspx?id=35
[15:03:22] <mrsun> archivist, if there is a set screw right under where the quill is sitting, could you check if its just an ordenary set screw or something more for me? :)
[15:03:30] <mrsun> requires you to unscrew it tho :P
[15:04:07] <archivist> picture of where your screw is :)
[15:04:43] * frallzor bets a nickle on 5/16 inch thread
[15:04:46] <mrsun> archivist, ough
[15:05:01] <mrsun> what is that part calle don a lathe ?
[15:05:41] <mrsun> tailstock :P
[15:05:42] <mrsun> maybe
[15:06:04] <archivist> ah the anti rotation screw?
[15:06:13] <mrsun> archivist, yes
[15:06:39] <mrsun> seen pictures of it being like a "box" on the top and then threaded
[15:06:43] <mrsun> could make one of those i guess
[15:06:49] <mrsun> screw it in then put the quill in
[15:06:52] <mrsun> and it cant rotate out
[15:07:00] <archivist> will be a few minutes
[15:07:18] <archivist> I expect a parallel end to the screw
[15:08:21] <mrsun> gah i just ripped my little toe nail off
[15:09:57] <mrsun> but need to clean up the groove ... they have been running it without that part for a long time it seems, and the "tightening" nut has been the thing holding it from rotating, so its kinda butchered :/
[15:10:16] <mrsun> i dont get it how someone can abuse a machine so much
[15:11:08] <mrsun> http://www.practicalmachinist.com/vb/attachments/f25/1143d1201033599-need-new-tailstock-quill-south-bend-10k-lathe-a962-1-.jpg my guess is that its somethingl ike that on yours
[15:11:33] <mrsun> on mine its screwed from the tailstock so its not sitting int he quill
[15:11:58] <Tom_itx> anonimasu what's up?
[15:22:47] <mrsun> original south bend gears doesnt seem to fit my lathe :/
[15:23:10] <mrsun> got bull gear of 123mm and 70 teeth, south bend ones seem to have 126mm and 76 teeth :/
[15:23:22] <mrsun> or wait
[15:23:30] <mrsun> 123.7mm ... seems right at the od
[15:23:35] <mrsun> so why does the teeth not match :P
[15:23:58] <mrsun> no its mine that has 126mm and 70T .... and aouthbend 123.7mm and 76 seeth :P
[15:30:49] <archivist> the anti rotation is a pin with angled end, that is held in by a side set screw pics in a mo
[15:35:38] <archivist> mrsun, still assembled http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_05_20_southbend/IMG_1244.JPG
[15:36:13] <archivist> the bits http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_05_20_southbend/IMG_1246.JPG
[15:37:16] <mrsun> biig pictures =)
[15:37:20] <archivist> grub is .309" dia
[15:37:54] <archivist> no edits to make them more better, you gets the raw info
[15:38:04] <Tom_itx> tomorrow
[15:38:30] <archivist> after everyone else tries to look too :(
[15:38:54] <archivist> crappy 256k upload rate
[15:39:23] <mrsun> omg, you realy disassembled it for me :P
[15:39:32] <mrsun> oh it seems like a totaly different system on that one =)
[15:39:32] <archivist> yup
[15:40:00] <mrsun> i guess ill make a brass set screw that has a square on the top, or a slot
[15:40:15] <archivist> was thinking of painting the tailstock the other day, now I might actually do it
[15:40:23] <mrsun> archivist, heh win win =)
[15:40:34] <Tom_itx> if you do, don't repost the pic :)
[15:42:43] <mrsun> have to call that company that had stock spare parts for my lathe tomorrow and see what they got =)
[15:42:54] <mrsun> if they have a bull gear or hell, a whole spindle and what it would cost
[15:42:59] <mrsun> my guess is expensive :/
[15:43:04] <archivist> is this fast enough http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_05_20_southbend/IMG_1244_1000.JPG
[15:43:29] * Tom_itx hugs archivist
[15:43:32] <archivist> new spindle....new bearings
[15:44:38] <mrsun> bearings doesnt need changing
[15:44:57] <mrsun> if the spindle has the same OD :P
[15:46:46] <mrsun> if i had money i would go to them, check what they got and buy some stuff for the lathe ... missing alot of tools like follower rest, steady rest, one of the gears was totaly chattered, new leadscrew ... :P
[15:47:38] <archivist> directory has scaled and full size pics now http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_05_20_southbend/
[15:50:13] <archivist> the lathe needed some de rusting due to a leaky roof, roof was another job I did something about today
[15:50:27] <mrsun> =)
[15:54:17] <andypugh> Took the fire engine to Kew Bridge pumping station today. A friend took a bunch of photos. There are some lovely big steam engines (and some small red ones) http://flickr.com/gp/27565507@N06/410m9Z/
[15:57:53] * archivist loves a picnic up the water tower there :)
[15:58:20] <andypugh> I was wondering if they let folk up the tower, but I was a bit too busy to check.
[16:00:38] <archivist> down the bottom of the page http://www.collection.archivist.info/searchv13.php?searchstr=kew
[16:06:14] <archivist> some of my pics are not in public areas of kew
[16:14:51] <alex4nder> hey
[16:15:10] <DJ9DJ> gn8
[16:38:22] <Spida> win 30
[16:38:26] <Spida> oops
[16:39:24] <Aero-Tec> the motor growling one one dir and not the other
[16:39:42] <Aero-Tec> it also goes at slow speeds
[16:41:00] <Aero-Tec> it was not errorring the drives but that may have changed
[16:41:33] <Aero-Tec> it is so hit and miss now
[16:41:48] <Aero-Tec> works most of the time
[16:42:12] <Aero-Tec> just every so often it will act up
[16:42:50] <Aero-Tec> I like a problem that does not run and hide
[16:43:22] <Aero-Tec> it's broke, I fix, it stays fixed
[16:43:32] <Aero-Tec> nice and clean
[16:44:32] <Aero-Tec> hate not knowing if what you have done fixed it or not
[16:44:57] <Aero-Tec> all one can do is keep playing with if and hope it is fixed
[16:45:37] <Aero-Tec> this problem is hell on tooling, and parts
[17:25:08] <JT-Shop> ethernet?
[17:25:15] <JT-Shop> MDesade: ^^
[17:25:24] <Aero-Tec> I have never played with a smooth stepper
[17:25:41] <JT-Shop> isn't that some device for mack3
[17:25:52] <Aero-Tec> yep
[17:26:16] <Aero-Tec> and I never heard of a ethernet version ether
[17:26:32] <Aero-Tec> not saying they have not made one
[17:26:55] <Aero-Tec> I have not kept up to date on smooth stepper
[17:27:11] <JT-Shop> wonder what the ethernet part does....
[17:27:35] <JT-Shop> never heard of a G213V drive either
[17:27:37] <frallzor> same as the PP
[17:27:38] <Aero-Tec> I would guess it would be in place of a USB port
[17:27:58] <JT-Shop> evening frallzor
[17:28:01] <frallzor> but in realtime i guess
[17:28:04] <frallzor> unlike usb
[17:28:19] <frallzor> hello mr JT-Shop
[17:28:23] <JT-Shop> LOL
[17:28:59] <Aero-Tec> is MD still here?
[17:29:02] <frallzor> http://www.lolz.se/uploader/pics/IMG_3979.jpg looks worse on the pictures, but its better irl =)
[17:29:30] <JT-Shop> cool
[17:29:33] <Aero-Tec> cool, what is it?
[17:29:42] <JT-Shop> Aero-Tec: his nick is still alive
[17:29:46] <frallzor> just a random remote-thingy shape
[17:30:00] <frallzor> with lots of 3D-features
[17:30:20] <JT-Shop> frallzor: how did you hold it?
[17:30:43] <Aero-Tec> is that code for "it my top secret project that will change the world"?
[17:30:43] <frallzor> I had a 1/4" flat iron
[17:30:51] <frallzor> no biggie
[17:31:23] <frallzor> or not feet, but you get what I go for =)
[17:31:30] <frallzor> or is " feet or inch?
[17:31:41] <Aero-Tec> so it was bolted to the flat iron?
[17:32:06] <MDesade> yes, i am using MACH, but the hardware is mostly the same...
[17:32:08] <frallzor> ill go im millimeter instead, did all machining down so there was 0.5mm left holding it
[17:32:20] <frallzor> and then just a final cut of the 0.5mm
[17:32:41] <Aero-Tec> ok
[17:33:10] <frallzor> 6mm thick, maching down so 0.5mm holding it, then a final 0.5 cut, all done
[17:33:46] <Aero-Tec> hello MD
[17:34:03] <Aero-Tec> MDesade: calling md
[17:34:25] <Aero-Tec> see if we can get more info from him
[17:36:09] <Aero-Tec> back to the fight with my lathe
[17:36:20] <JT-Shop> who is winning?
[17:36:59] <Aero-Tec> right now the lathe
[17:37:10] <frallzor> hmm I set my tool at 32.5mm JT-Shop
[17:37:11] <Aero-Tec> the problem keeps coming and going
[17:37:12] <JT-Shop> yuck
[17:37:19] <Aero-Tec> but mostly it is gone
[17:37:27] <JT-Shop> electrical?
[17:37:51] <Aero-Tec> not sure, but most likely
[17:37:52] <frallzor> why does it something change to like 32.4 when homing the same way as I allways do
[17:37:59] <frallzor> *sometimes
[17:38:42] <JT-Shop> what changes?
[17:38:44] <Aero-Tec> both motors will work good one dir and growl in the other dir
[17:39:05] <frallzor> JT-Shop the home-value
[17:39:14] <JT-Shop> Aero-Tec: stepper?
[17:39:16] <frallzor> it should allways be 32.5 when offset
[17:39:22] <Aero-Tec> if the dir sig is high it may growl
[17:39:29] <Aero-Tec> servos
[17:39:38] <Aero-Tec> but step and dir
[17:39:46] <Aero-Tec> gecko drives
[17:40:07] <Aero-Tec> the encoders are solid
[17:40:34] <Aero-Tec> not loose and the wheel is solid on motor shaft
[17:40:59] <Aero-Tec> it work great most of the time
[17:42:25] <JT-Shop> frallzor: are you talking about when you do a G53 G0 X0 or something the DRO reading?
[17:42:26] <Aero-Tec> some time you hear that it is not real smooth, just a slight noise witch means it is missing steps
[17:42:49] <Aero-Tec> other time it is a growl, ton of missing steps
[17:42:59] <frallzor> nah when I run code I use my toolsetter and set the home position of Z
[17:43:04] <JT-Shop> Aero-Tec: are you using shielded wire for any part?
[17:43:22] <Aero-Tec> encoders are sheilded
[17:43:35] <frallzor> when I switch files now when using this new PP it somethings doesnt set the home Z as 32.5 rather other number
[17:43:36] <Tom_itx> on shielded wire do you leave the shield ungrounded on one end?
[17:43:39] <JT-Shop> shield drain is grounded only on one end?
[17:43:51] <Aero-Tec> thing is it can come and go
[17:44:09] <Aero-Tec> was tied to the neg of the 5 volt supply
[17:44:09] <Tom_itx> JT-Shop why is that important?
[17:44:17] <JT-Shop> frallzor: how are you reading the "home" value
[17:44:18] <Tom_itx> i've heard that before
[17:44:26] <Aero-Tec> now it is free floating
[17:44:34] <MDesade> hello Tom_itx
[17:44:38] <JT-Shop> Tom_itx: if you ground it on both ends you create a current loop and that will drive electrons nuts
[17:44:40] <MDesade> who is MD?
[17:44:41] <frallzor> its an offset from the toolsetter when it stops jogging
[17:44:49] <Tom_itx> JT-Shop ok
[17:44:51] <MDesade> Aero-Tec who is MD?
[17:44:59] <Tom_itx> i figured it was something like that
[17:45:02] <Tom_itx> MDesade ?
[17:45:05] <Aero-Tec> you
[17:45:09] <JT-Shop> Aero-Tec: not connected on either end or connected on one end?
[17:45:42] <Aero-Tec> not sure if the motor end is connected
[17:45:50] <Aero-Tec> can check
[17:45:53] <MDesade> ah, gotcha
[17:46:04] <frallzor> I want to blame the PP, its like it makes the bottom move
[17:46:05] <MDesade> ah, gotcha...
[17:46:07] <JT-Shop> power is flicking on and off !
[17:46:24] <Aero-Tec> MDesade: you were asking for help and we got talking it over and wanted more info from you
[17:46:35] <Aero-Tec> power is fine
[17:46:36] <JT-Shop> frallzor: see if the g code is what is moving
[17:46:52] <JT-Shop> Aero-Tec: no, mine is blinking
[17:47:00] <frallzor> i think the EMC PP is doing more than it really should
[17:47:16] <Tom_itx> out to do some wiring
[17:47:18] <JT-Shop> that I agree on
[17:47:26] <Aero-Tec> MDesade: you said your using smooth stepper, are you running mach?
[17:47:30] <Tom_itx> and make a test fixture to hold all this stuff
[17:47:31] <MDesade> Tom_itx you gave me some initial advice a few months ago, about converting that Smithy to a CNC... I sold that machine, bought a bridgeport series 1 CNC, gutted the electronics and motors, and rehabbed it from the ground up
[17:47:44] <Tom_itx> i did?
[17:48:02] <Aero-Tec> MDesade: also when did smooth stepper start making a ethernet version?
[17:48:04] <MDesade> Aero-Tec yes and yes. (i know this is a linux room, but i was asking about the hardware)
[17:48:10] <jdhNC> I have set all my home velocities to 0 (no home/limit switches wired up yet) but it still tries to do home movement. Is there something I am missing?
[17:48:21] <frallzor> I think ill stick to the mach2 PP for now, it seems to work the best =)
[17:48:26] <JT-Shop> Aero-Tec: make sure the shield and drain wire is connected to a solid ground on one end only
[17:48:56] <Tom_itx> MDesade sounds like a bold project
[17:48:59] <JT-Shop> jdhNC: do you have home sequence in your ini?
[17:49:05] <Aero-Tec> JT-Shop: will check that, thanks
[17:49:20] <jdhNC> JT: I've tried taking them out, no change.
[17:49:34] <MDesade> Tom_itx yeah, i'm 5 grand into this
[17:49:41] <Tom_itx> can't stop now
[17:49:46] <JT-Shop> pastebin your ini file for us to look at
[17:50:06] <Tom_itx> ok, i'm afk to work on my drivers and psu wiring
[17:50:10] <JT-Shop> wow 5k is a bunch to convert a knee mill
[17:50:14] <jdhNC> it will take me a minute
[17:50:30] <MDesade> Tom_itx yeah, it's going to work one way or another
[17:50:31] <JT-Shop> ok, I'll brb
[17:50:31] <Aero-Tec> MDesade: when did smooth stepper start making a ethernet version?
[17:51:07] <MDesade> Aero-Tec i'm not sure, best i can tell you, it's been a while...
[17:51:33] <Aero-Tec> last I hear they just had USB
[17:51:49] <MDesade> JT-Shop - yes, but that includes the price of the Bridgeport itself
[17:52:05] <Aero-Tec> there was talk of a ethernet version but it sounded a long way off
[17:52:41] <jdhNC> JT: http://pastebin.com/EJFxYHS1
[17:52:49] <MDesade> JT-Shop - AND, I'm not buying crap components. it's all NEW parts, new everything. new computer, new touchscreen. no hand-me-downs
[17:53:18] <Aero-Tec> what are you going to make with the new machine?
[17:53:40] <frallzor> doing an interesting test now JT-Shop, simple contour operation, PPed with both the EMC PP and the generic mach2 PP that also works
[17:53:56] <MDesade> Aero-Tec under MACH i can see the data going to the smoothstepper, however it is connected to CNC4PC's C32 breakout board, and i "think" that is where the problem is
[17:54:00] <Aero-Tec> you got plans? or are you just having fun with it?
[17:54:25] <MDesade> Aero-Tec it's for my business. we make a sprinkler timer.
[17:54:42] <Aero-Tec> cool
[17:54:51] <JT-Shop> frallzor: try the RS274 one too
[17:55:18] <MDesade> hehe, besides? every man needs one in his garage? don't all my neighbors have an industrial shop in theirs??
[17:55:21] <MDesade> haha!!
[17:55:27] <Aero-Tec> MDesade: so what is the problem exactly?
[17:55:28] <frallzor> the EMC one uses G1/G3 on every single move
[17:55:52] <frallzor> G1/G3/G1/G3 over and over again
[17:56:37] <Aero-Tec> do you have to use g1 and g3 all the time?
[17:56:55] <frallzor> well the Post Processor seems to think thats cool
[17:57:11] <frallzor> it switched between G1 and G3 every row
[17:57:14] <frallzor> *s
[17:57:34] <MDesade> Aero-Tec ok, so i load up some G-code and execute it. I see it sending the data to the smoothstepper in the MACH plugin. AND it's lights are blinking like it's receiving the data. the port 1&2 are connected directly to the C32 breakout board, which then connect to the Gecko G213V drives, and to the Keling NEMA42's
[17:58:22] <Aero-Tec> and does it move?
[17:58:23] <MDesade> the motors are not moving, and the C32 lights are not blinking on those 3x axis, meaning somewhere on that board, it is not moving the data to the drives
[17:58:26] <Aero-Tec> buzz?
[17:58:29] <MDesade> no and no
[17:58:54] <frallzor> JT-Shop RS-PP looks alot like the EMC output
[17:59:09] <JT-Shop> steppers are solid when powered up ie they can't be moved by hand?
[17:59:19] <MDesade> just holding still (you can feel the shafts are are their "holding current" since they move freely with no power)
[17:59:19] <frallzor> or pretty much the same minus the NXXX at every row atm
[17:59:21] <JT-Shop> frallzor: ok
[18:00:05] <MDesade> the pulleys are NOT connected to the table, so it won't move or break anything by testing it
[18:00:07] <Aero-Tec> some of the BOBs were having problems with bad optos
[18:00:20] <MDesade> ah...
[18:00:20] <Aero-Tec> cool that is good
[18:00:42] <MDesade> no amber or red lights on the Gecko's just a green power light
[18:01:39] <JT-Shop> MDesade: how is the system connected to each other bob > gecko?
[18:03:28] <MDesade> JT-Shop CNC4PC sells these RJ45 connectors specifically for the Gecko's, so i have 3x of those screwed onto the taps on the Drives, and then a 12 inch CAT5 wire to the C32 BOB which directly plugs into it's RJ45
[18:04:32] <jdhNC> geez.. it was the HOME= line I had typoed
[18:05:12] <JT-Shop> MDesade: the cat5 wire is for step and direction?
[18:05:51] <MDesade> Also, i have a 270K ohm resistor on the Gecko's to limit the current to 6amps, matching the current requirement for the Keling NEMA-42s
[18:06:41] <JT-Shop> when the gecko drive is powered up you should not be able to turn the stepper by hand and you say you can?
[18:06:54] <MDesade> yes: disable, step, dir and common. those 4 pins it from the BOB via the CAT5
[18:07:20] <MDesade> JT-Shop no, not with power. they are holding. without power, yes i can
[18:07:46] <JT-Shop> and the led is green on the 213?
[18:08:41] <MDesade> since i have the power supplies connected via a big disconnect and 240V, i can power off the motors and spindle VFD without messing with the computer
[18:08:54] <MDesade> JT-Shop the light IS green
[18:09:29] <MDesade> like i said, i "think" it's signal is not making it through the C32 BOB....
[18:09:34] <Aero-Tec> NEMA-42s only taking 6 amps?
[18:09:42] <Aero-Tec> that sounds wrong
[18:09:45] <MDesade> thus , even though this is a Linux room, it's the same hardware
[18:10:00] <Aero-Tec> they should be able to take the full output
[18:10:11] <MDesade> Aero-tec - ill send you a link, showing you how i have it wired? it's bi-polar paralell
[18:10:44] <Aero-Tec> did you try the smooth stepper forum
[18:11:04] <Aero-Tec> also the cnc4pc forum
[18:11:14] <Aero-Tec> they would be of more help
[18:11:14] <JT-Shop> MDesade: the led color on the 213 is?
[18:12:07] <JT-Shop> seems a complicated way to drive a gecko stepper drive to me
[18:12:08] <MDesade> http://kelinginc.net/NEMA42Motor.html
[18:12:18] <MDesade> JT-Shop GREEN!!
[18:12:40] <JT-Shop> ok, 213 is healthy
[18:13:10] <MDesade> JT-Shop actually, it's pretty simple? it's provides a quick disconnect
[18:13:13] <JT-Shop> I've blown optos on breakout boards connecting them up wrong before
[18:13:26] <MDesade> yeah, the problem is in the C32
[18:13:56] <JT-Shop> but you have the speed limits of a parallel port and for the same money you could get 10x better performace with a 5i25/7i76 combo
[18:14:42] <MDesade> JT-Shop as have I... however, they usually crack the plastic on their case, which visually everything looks ok, and i haven't gotten rough with any of this stuff. its all new
[18:15:19] <JT-Shop> ok the c32 has an enable line yes?
[18:15:31] <MDesade> JT-Shop. the smoothstepper takes care of a lot of the parallel issues.
[18:15:37] <MDesade> yes
[18:15:56] <JT-Shop> where is the smooth stepper in the chain?
[18:16:17] <Aero-Tec> the smooth feed the BOBs
[18:16:44] <Aero-Tec> some comp to smooth to BOBs to drives to steppers
[18:16:50] <Aero-Tec> from
[18:17:32] <robin_sz> ping?
[18:17:37] <robin_sz> did everyone die?
[18:17:40] <syyl_> peng!
[18:17:45] <robin_sz> obviously not
[18:17:46] <JT-Shop> phhhhhh
[18:17:47] <Aero-Tec> ping back
[18:17:53] <MDesade> the smoothstepper gets it's signal over ethernet, and in the MACH panel, i see it sending and receiving just fine
[18:17:58] <robin_sz> well, apart from Jymm's parrot
[18:18:14] <JT-Shop> MDesade: so you have $400 worth of hardware that still uses the parallel port?
[18:18:37] <JT-Shop> ok I forgot we are talking mack here
[18:18:37] * robin_sz listens up
[18:18:39] <MDesade> it seems to be blinking rapidly when i send G-code to it, and just isn't moving the motors...
[18:18:47] <MDesade> JT-Shop yes, that is the poop
[18:18:50] <Aero-Tec> Mesa boards would have been better and cheaper
[18:18:53] <robin_sz> yes
[18:18:58] <robin_sz> Mesa ftw
[18:19:08] <JT-Shop> Aero-Tec: for linuxcnc for sure but not for mack
[18:19:19] <Aero-Tec> true
[18:19:25] <JT-Shop> mack has to use workaround hardware like smoothsteppers
[18:19:28] <Aero-Tec> BTW mach3
[18:19:32] <Aero-Tec> not mack
[18:19:34] <Aero-Tec> lol
[18:19:38] <JT-Shop> who cares
[18:19:43] <robin_sz> I never had anything but deep fails with Mach
[18:19:46] <Aero-Tec> mack is the truck
[18:19:57] <JT-Shop> ok it's a truck too
[18:20:05] <Aero-Tec> I have had problem with mach as wel
[18:20:13] <Aero-Tec> thus my being here
[18:20:17] <JT-Shop> I never could get mack to run well
[18:20:35] <robin_sz> It cost me a lot trying to get it to run plasmas
[18:20:38] <robin_sz> it never did
[18:20:53] <robin_sz> the biggest problem (apart from realtime glitches)
[18:20:54] <Aero-Tec> I have had it go top speed through my part
[18:20:54] <MDesade> i tired the linux EMC, i couldn't get the newer version to run, but the older one did... i "think" i have it loaded still on another hard drive in my office
[18:21:00] <robin_sz> was the macros
[18:21:31] <robin_sz> some years ago, EMC was a complete pig to install
[18:21:35] <MDesade> however, i don't believe my issue here has anything to do with the software
[18:21:41] <robin_sz> these days, with the live CDs etc, its a snap
[18:21:43] <Aero-Tec> was doing a run, had made like 20 parts, half way through part 21 it tried to go though the part at full speed
[18:21:46] <MDesade> it's a hardware issue
[18:21:48] <JT-Shop> MDesade: you can run any version of LinuxCNC from 8.04 or 10.04
[18:22:07] <Aero-Tec> stalled every thing, big cutter so it did not break
[18:22:08] <MDesade> i couldn't get 10.04 to load properly, but 8.04 did
[18:22:14] <JT-Shop> MDesade: I agree it is a hardware issue
[18:22:38] <robin_sz> more likely, smoothstepper is not being correctly addressed by mach
[18:22:46] <MDesade> this is a ASUS intel Atom proc, 4 gigs of RAM, 128gig SSD, so it's got plenty of performance
[18:23:06] * robin_sz shrugs
[18:23:21] <MDesade> robin_sz no, i see all the lights blinking like it's getting the signal. it's NOT the smoothstepper.
[18:23:43] <robin_sz> and what is that signal telling it to do
[18:23:44] <JT-Shop> interesting enough you don't need mega computers to run a CNC machine a D525 for $80 works great
[18:23:51] <MDesade> i could prove it with my o'scope. but, again, its not software
[18:24:25] <robin_sz> so, let me get this right ...
[18:24:31] <MDesade> JT-Shop for whatever it's worth, i use linux wherever i can, but i ended up liking MACH3 better, so i ran with it
[18:24:40] <robin_sz> you have the ethernet smoothstepper?
[18:25:36] <robin_sz> and when you say "you see all the lights blinking" .. what lights exactly?
[18:25:39] <robin_sz> the shop lights?
[18:25:45] <robin_sz> the ethenet comms lights?
[18:26:03] <Aero-Tec> I got to go spend time with the lathe and see if I can track down the glitch
[18:26:07] <JT-Shop> MDesade: no problem if you like something use it
[18:28:06] <Aero-Tec> MDesade: one word of warning, lots of guys have had mach make wrong moves, break probes and probe tips, cutters and parts
[18:28:09] <MDesade> ok, cool. i just didn't want to start a big religious debate on linux vs windoze, etc. my love for the penguin is not the issue here
[18:28:17] <Aero-Tec> I am one of them
[18:28:27] <MDesade> LOL... fair enough
[18:28:55] * frallzor just made a girl cry over a joke
[18:29:03] <jdhNC> as an opinion, win* is not suitable for real-time.
[18:29:26] <Aero-Tec> I do really like the mach interface and easy of use and setup
[18:29:29] <robin_sz> well, you may do better on the Mach forum, afaik, there is no EMC driver for the smoothstepper, so we are unlikely to have any useful assistance
[18:29:46] <jdhNC> I'd like to have some of the mach wizards
[18:30:22] <robin_sz> Aero-Tec, yeah, the interface is nice, and highyl cofigurable, but the threadign sucks ... it used to lock up in macros .. and macros seemed to get confused as to order of exectution
[18:30:31] <MDesade> well, the issue is the CNC4PC breakout board, that can be used in EITHER OS environment. so, if any of you have used a C32 BOB, i'm all ears here
[18:31:05] <robin_sz> I thought is was smoothstepper?
[18:32:01] <MDesade> my experience with either MACH or EMC is: when you use a old POS computer, and try to have it do "realtime", there tends to be problems. however, if you BUILD a new PC, specifically built for whatever it's job is. it just works better
[18:32:29] <robin_sz> mine is the opposite
[18:32:48] <JT-Shop> mine is the opposite
[18:32:54] <jdhNC> same here, but
[18:33:02] <robin_sz> i find of fthe shelf old Dell's work fine for EMC, and its the "home built" attempts that never work
[18:33:08] <MDesade> the smoothstepper has two parallel ports. which connect directly to the C32. the signal is getting to the smoothstepper just fine, but i'm NOT getting the motors to move, and "seems" to be getting lost in the C32
[18:33:22] <jdhNC> are you sure you have a smoothstepper?
[18:33:26] <robin_sz> yeah, as I said, software issue
[18:33:45] <robin_sz> "the signal" as you put it is a ethernet signal
[18:33:54] <robin_sz> it has to tell the smoothstepper what to do
[18:34:02] <robin_sz> its telling it to do the wrong thing
[18:34:09] <MDesade> no
[18:34:16] <robin_sz> ok, then it all works, hurrah
[18:34:44] <jdhNC> you have a smoothstepper with a parallel port?
[18:35:03] * robin_sz asked him that way back up there
[18:35:19] <MDesade> when you send it a signal, regardless of HOW. ethernet, parallel, smoke signals? whatever, the lights blink faster and so on. so i can SEE the thing is getting the signal to move. the BOB has 3 LEDs per axis, and those are NOT lighting up
[18:35:31] <robin_sz> "the lights"
[18:35:40] <robin_sz> I asked you what lights
[18:35:54] <robin_sz> you did not answer
[18:35:59] <jdhNC> you are talking to a smoothstepper via a p-port breakout board?
[18:36:15] <JT-Shop> I think it is this one http://www.cnc4pc.com/Store/osc/product_info.php?products_id=366
[18:36:37] <JT-Shop> like I said a very complex slow way to drive a stepper
[18:36:44] * JT-Shop just shakes his head
[18:37:10] <robin_sz> well, he doesnt want to seem to tell us what it is
[18:37:15] <MDesade> JT-Shop yes, that's it
[18:37:24] <MDesade> and here is the BOB http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=255
[18:37:40] <robin_sz> so WHAT LIGHTS blink faster???????
[18:37:50] <robin_sz> the ethernet comms lights?
[18:38:40] <JT-Shop> MDesade: I assume you have to have some magic settings in mack for the smooth stepper to work properly
[18:38:45] <MDesade> robin_sz there are 4x LEDs on the ethernet smoothstepper. yes, 2x (i think) are ethernet comm LEDs
[18:38:57] <robin_sz> so, it is a software isssue
[18:39:00] <MDesade> JT-Shop yes, it comes with a software driver
[18:39:03] <robin_sz> the unit is receiving comms
[18:39:09] <robin_sz> but the instructions are wrong
[18:39:36] <JT-Shop> MDesade: what mode is the smoothstepper board configured for?
[18:39:39] <MDesade> ok robin, it's software
[18:39:41] <robin_sz> surely the best place to ask is the mach forum, they will have a confiuration tester etc?
[18:39:43] <MDesade> sheesh?
[18:40:01] <MDesade> JT-Shop what do you mean?

[18:40:23] <JT-Shop> the smoothstepper board is configurable for mode when you power it up
[18:40:42] <JT-Shop> btw, the hardware is mack specific
[18:40:51] * robin_sz nods
[18:41:06] <jdhNC> so, it is Mock->smoothstepper->C32->stepper?
[18:41:11] <JT-Shop> there is a jumper on the board for mode what position is it in?
[18:41:20] <MDesade> JT-Shop right, but what modes are you asking about?
[18:41:26] <JT-Shop> jdhNC: I think so
[18:41:42] <MDesade> jdhNC yes that is right
[18:41:47] <JT-Shop> http://warp9td.com/documentation/ESS-TroubleshootingGuide.pdf
[18:42:21] <jdhNC> I'd hate to be their support guy!
[18:42:22] <robin_sz> I would have hoped Mach3 was able to detect and check the heatlh of its attached motion controller
[18:42:53] <JT-Shop> MDesade: is it possible to just take the smoothstepper out of the loop to verify the health of the bob?
[18:44:26] <JT-Shop> it's so much simpler to just plug in a 5i25 to the pci slot and plug the 7i76 into it and wire up your drives and have 10x the performance of the smooth stepper for $200!
[18:45:20] <robin_sz> the C32 is just an expensive paralell port isolator .. you can check that easily with Mach, as its simple to assign pins and toggle them in Mach
[18:45:43] <MDesade> JT-Shop - ok, the IP address on it is a little screwy "out of the box" however, i DO have the IP all setup static, and it's ping-able and comms just fine. i have a netgear 5-port gigabit switch built into this whole panel that runs the bridgeport
[18:46:28] <jdhNC> speaking of mesa... for a 7i37TA, can I run +5vdc -NC switch->ibit+ on the 7i37, then ibit->4.7k->gnd? No issues with current?
[18:47:26] <robin_sz> I think from memory it can source 5ma
[18:47:33] <robin_sz> but Id have to check
[18:47:43] <pcw_home> No resistor needed
[18:47:43] <MDesade> JT-Shop good question. i need to purchase a couple of parallel cables to make that happen
[18:48:14] <pcw_home> 7I37 inputs are good from 3 to 24VDC
[18:48:18] <jdhNC> cool, that will make things prettier.
[18:48:51] <MDesade> if there was time, before the eclipse, i'd run to frys electronics and get a couple right now. but? i want to see this celestial event, as the last one was in 1994
[18:49:01] <pcw_home> if the red LED lights you have the input backwards
[18:49:20] <robin_sz> eclipse
[18:49:24] <robin_sz> tonight?
[18:49:27] <MDesade> yes
[18:49:31] <robin_sz> coo
[18:49:37] <JT-Shop> MDesade: so your jumper is on wakeup mode or bootp mode?
[18:49:39] <MDesade> in about an hour it starts
[18:49:40] <robin_sz> wonder if I can see it from uk
[18:49:50] <MDesade> JT-Shop wakeup
[18:49:57] <JT-Shop> ok
[18:50:26] <robin_sz> does mach not have a way to say "yes, I can see it and I am talking to it"?
[18:50:34] <MDesade> i was one a cisco CCNP, and setting an IP address and such is no biggie.
[18:51:44] <jdhNC> I worked at an answering service in college.
[18:51:59] <JT-Shop> I used to bury dead horses
[18:52:05] <jdhNC> you win!
[18:52:05] <MDesade> i'm hesitant to tell you how i have it here, as i'm sure i will get pounced on about "software" and such, but? my windoze box has two IP addresses
[18:52:15] <jdhNC> OMG!
[18:52:18] <jdhNC> so does mine!
[18:52:33] <jdhNC> sorry, that was uncalled for (but it does)
[18:52:43] <robin_sz> I am not foolish enough to allow my wondows box on the network :)
[18:52:57] <robin_sz> except on special occasions
[18:52:59] <jdhNC> robin: live a little!
[18:53:02] <MDesade> in windoze (or linux) you can setup a sub-interface where you have two IPs
[18:53:34] <JT-Shop> seems the "event" is on the left coast only...
[18:53:34] <robin_sz> even the kids machine is linux now, after the little pests installed so many virus that it would not evne boot
[18:53:54] <robin_sz> "ooh look, free game ... and its an .exe ... "
[18:54:06] <jdhNC> robin: good idea. My daughter used to do that all the time.
[18:54:07] <MDesade> so, since the Ethernet smoothstepper comes out of the box in wakeup mode with an IP of, i have my box setup as AND a sub-if of 10.0.0.X for my local LAN
[18:54:15] <andypugh> robin_sz: You gave them Admin accounts?
[18:54:52] <alex4nder> sick
[18:55:08] <alex4nder> ReadError: I got spindle on/off and coolant on/off working
[18:55:14] <alex4nder> it was surprisingly easy.
[18:55:22] <JT-Shop> nice
[18:55:42] <ReadError> ive uses a SSR in my RIMS
[18:55:46] <ReadError> works pretty simple
[18:55:57] <ReadError> feed 5-12v = on
[18:56:01] <andypugh> I wonder if it would be considered wasteful to use just the sserial parts of a 7i76 for spindle control?
[18:56:08] <robin_sz> you could do worse than fire up wireshark and try to see what crap is going backwards and forwards
[18:56:15] <alex4nder> ReadError: yup
[18:56:53] <alex4nder> these are the opto 22s that someone recommended to me the other day
[18:58:24] <Tom_itx> JT-Shop, not visible from your fort?
[18:59:20] <Tom_itx> 'in about an hour' does little good when i come back in and re'read the scrollback...
[18:59:21] <JT-Shop> no it will be over the hill... have to be standing in Donner pass to see it I think
[18:59:42] <Tom_itx> lunar?
[18:59:44] <JT-Shop> google eclipse today
[18:59:54] <Tom_itx> why when i can ask you?
[18:59:55] <Tom_itx> :D
[19:00:06] <MDesade> you guys are all over the pond in the UK?
[19:00:16] <Tom_itx> who guys
[19:00:18] <Tom_itx> not me
[19:00:33] <MDesade> JT-Shop for one
[19:00:44] <Tom_itx> no, he's my next door neighbor
[19:00:48] <MDesade> Tom_itx i am in phoenix, AZ
[19:00:50] <Tom_itx> one state over
[19:00:50] <andypugh> It's 0050 in the UK, only the wierd are still up. (like robin)
[19:00:57] <Tom_itx> ks
[19:01:37] <MDesade> Tom_itx BTW, I do appreciate (or did) your help a few months back, about that Smithy CB-1220-XL
[19:02:48] <MDesade> Tom_itx you also referred me to Keling, to buy the steppers/servos which they are a decent motor for the price. so, thank you for the vendor referral
[19:02:55] <andypugh> Time I logged, in fact.
[19:03:10] <Tom_itx> bye andy
[19:03:25] <Tom_itx> oh
[19:04:05] <MDesade> so, thank you is all i was saying
[19:04:18] <Tom_itx> np
[19:04:23] <Tom_itx> i wish i remembered
[19:04:30] <Tom_itx> i sorta do
[19:04:34] <MDesade> haha! it's no biggie
[19:04:36] <JT-Shop> MDesade: don't get confused by the mack knocks we all hang out here cause we like to help people with CNC
[19:05:17] <MDesade> fair enough... i figured you guys would at least know about the CNC hardware
[19:05:18] <jdhNC> personally, I like to be helped.
[19:06:00] <JT-Shop> yea, the gecko drives and breakout boards but not mack specific hardware like smoothstepper
[19:06:04] <Tom_itx> i help alot in avr and other channels, i can't keep track
[19:06:27] <Tom_itx> oh, JT-Shop i did have a question about the geckos
[19:06:40] <Tom_itx> when i set the pot... does that ever change?
[19:06:57] <Tom_itx> ie if i hook the driver up to a different controller
[19:07:06] <JT-Shop> no, once you set it for smooth running in the mid range you never mess with it again
[19:07:21] <Tom_itx> so it's set for the motor, not the input signal?
[19:07:26] <JT-Shop> it is between the stepper and the drive and has nothing to do with the controller
[19:07:31] <Tom_itx> good
[19:07:32] <JT-Shop> aye
[19:07:43] <Tom_itx> i may use this new setup on my old controller for a bit
[19:07:56] <Tom_itx> before i switch over to the mesa cards
[19:07:56] <skunkworks__> MDesade: does the bob have a charge pump?
[19:08:02] <Tom_itx> and linuxcnc
[19:08:10] <Tom_itx> i have both all set up
[19:08:47] <jdhNC> the axis arrow keys should move the table properly relative to the spindle, not move the table in the direction of th arrows?
[19:09:00] <JT-Shop> jdhNC: aye
[19:09:07] <Tom_itx> JT-Shop, the other question about it was; will i need to reset it if i rewire the stepper for parallel mode?
[19:09:12] <Tom_itx> it's in series right now
[19:09:13] <JT-Shop> think of the bit moving not the table
[19:09:36] <Tom_itx> but i plan to rewire them for parallel for the new drivers
[19:09:40] <JT-Shop> don't have a clue, I've only wired mine one way
[19:09:43] <jdhNC> that's a pretty simple concept that I had issues with due to my only other machine being a gantry router where it was thsame thing.
[19:09:47] <Tom_itx> JT-Shop, np
[19:09:53] <Tom_itx> i'll figure that out
[19:10:03] <MDesade> skunkworks_ yes
[19:10:44] <skunkworks__> is it setup correctly?
[19:10:50] * skunkworks__ has not clue really....
[19:10:59] <MDesade> i think so
[19:11:02] <JT-Shop> hi skunkworks
[19:11:14] <skunkworks__> Hey!
[19:13:03] <JT-Shop> MDesade: can you jumper the charge pump out to test the bob?
[19:13:16] <MDesade> i've tried both ways
[19:13:40] <robin_sz> pesky interweb
[19:13:44] <ReadError> so i didnt realize
[19:13:50] <ReadError> the company EMC made you all change the name
[19:14:12] <robin_sz> they did?
[19:14:16] <MDesade> really? they did?
[19:14:21] <ReadError> yea
[19:14:26] <ReadError> thats what wiki said
[19:14:29] <robin_sz> well well
[19:14:39] <JT-Shop> yea, they wanted top google hits
[19:14:43] <MDesade> wasn't it originally called "blue collar linux" and THAT changed to linuxEMC? now it's changing AGAIN??
[19:14:55] <robin_sz> no
[19:14:57] <JT-Shop> not that I know of
[19:14:59] <robin_sz> it was always EMC
[19:15:01] <ReadError> thats pretty lame of them
[19:15:08] <JT-Shop> EMC > EMC2 > LinuxCNC
[19:15:09] <MDesade> 13 years ago, it was
[19:15:22] <JT-Shop> and EMC was the name that NIST used
[19:15:24] <robin_sz> never heard of "blue collar linux"
[19:15:31] <robin_sz> it was EMC when NIST wrote it
[19:16:14] <robin_sz> it may well have been included in a distro called "blue collar linux" that I never heard of though
[19:16:34] <MDesade> back in the late 90's there WAS a distro called "blue collar Linux" and it got either renamed or absorbed into the linux-EMC tree
[19:17:08] <robin_sz> nope
[19:17:29] <MDesade> i don't remember if it was redhat/centos or slackware based....
[19:17:37] <robin_sz> emc is the NIST control package
[19:17:39] <MDesade> it's been a long time.... oh well?
[19:18:01] <robin_sz> and the current distro was put together by the guys here
[19:18:10] <robin_sz> there was the EMC BDI before that
[19:18:19] <robin_sz> by Paul Corner
[19:18:27] <robin_sz> who has disappeared afaik
[19:18:36] <JT-Shop> I never could get the BDI to work so I must be Brain Dead
[19:18:38] <robin_sz> I dont think we ever got all the build tools for that
[19:18:48] <robin_sz> I occasiaonally did
[19:18:57] <robin_sz> but not with a whole lot of success
[19:19:04] <JT-Shop> he got mad for some reason and forked off iirc
[19:19:24] <JT-Shop> speaking of forks... time to fire up the barbie here
[19:19:28] <robin_sz> yeah, it was long and involved
[19:19:29] <JT-Shop> see you guys later
[19:19:40] <robin_sz> buh byee
[19:19:46] <ReadError> why did NIST stop dev on it?
[19:19:58] <robin_sz> it had run its course
[19:20:08] <robin_sz> and tbh, it sucked a little
[19:20:20] <robin_sz> it was the guys first ever C++ project, and it showed
[19:21:18] <robin_sz> it badly needed re-writing ... and dumping of various bits, which has mostly happened
[19:22:06] <robin_sz> part of the problem was passing of messages in concrete data types, instead of a generic message containing a type, or at least casting it to a generic type
[19:22:24] <ReadError> i must say
[19:22:27] <ReadError> it works really nice now :)
[19:22:31] <robin_sz> so every time we wanted to add a new message to hte NML, we had to recode the whole thing
[19:22:39] <robin_sz> yeah, a LOT has happened
[19:22:57] <robin_sz> paul was very much agaisnt soemof the changes if I recall correctly and off he went
[19:23:08] <robin_sz> HAL was the last straw
[19:23:28] <robin_sz> there was much friction etc, but, thats how it goes sometimes
[19:24:19] <robin_sz> if I had known EMC corp wanted concessions, I could have lent you my tame patent lawyer :)
[19:24:40] <robin_sz> we could have had a few hundred K of development money out of them :)
[19:28:09] <jdhNC> the linuxcnc logo looks like crap with a .25 endmill in MDF
[19:34:55] <robin_sz> thats because it is supposed to be gut with a 50mm ball cutter into a 4 ton steel billet
[19:35:14] <robin_sz> :)
[19:35:57] <robin_sz> a friend is using the Vectric stuff to generate code for his router to great effect
[19:36:11] <robin_sz> seems a top qulaity bit of sofwtware for the money
[19:36:55] <ReadError> visualmill = mmmmmm
[19:36:56] <jdhNC> I bought a copy of cut-2d for my router
[19:37:04] <ReadError> i didnt like cut2d...
[19:37:07] <robin_sz> yeah, he has visual mill too
[19:37:15] <ReadError> visualmill is _awesome_
[19:37:22] <robin_sz> it is for milling
[19:37:23] <jdhNC> what's not to like, for 2d cutting?
[19:37:31] <robin_sz> its no use for the router thhough
[19:37:39] <robin_sz> cut2d has some limitations
[19:37:49] <ReadError> not as flexible as i would like
[19:37:55] <jdhNC> sure, it only does plain 2d
[19:37:57] <ReadError> you have 4 options, all very concrete
[19:38:12] <robin_sz> when we enquired they said "ah yes, thats deliberate ... you need cut 3d to get that option"
[19:38:12] <jdhNC> what would you add?
[19:38:29] <ReadError> ive cut about 4 different parts using visualmill
[19:38:32] <jdhNC> how many 2d ops are there?
[19:38:38] <ReadError> i can bang out a toolpath in 15 minutes or less now ;)
[19:39:05] <robin_sz> they dont include basic part nesting in cut 2d (minimum gap between parts, gap to edge)
[19:39:23] <robin_sz> yeah, its OK when you get used to it
[19:39:41] <robin_sz> stuff like edge pocketing
[19:39:57] <robin_sz> we do a lot of stuff where the DXF is a sqaure
[19:40:06] <robin_sz> with a line 20mm from one side
[19:40:10] <ReadError> i import into visualmill using igs
[19:40:13] <ReadError> works awesome
[19:40:38] <robin_sz> we need to cut the rebate, 20mm from the edge, then cut out the square
[19:40:45] <robin_sz> cut2d has trouble with that
[19:41:02] <robin_sz> we have to draw a 20mm wide oblong, machine that, then machine the square
[19:41:16] <robin_sz> ReadError, but no use for routing afaik
[19:41:30] <robin_sz> ReadError, wont do bridges for example
[19:41:52] <ReadError> i like the enter/exit strats
[19:41:59] <robin_sz> yep
[19:42:00] <ReadError> ended up with a much nicer cut
[19:42:09] <robin_sz> its awesome on our Haas
[19:42:35] <robin_sz> but cut2d works better for our router
[19:43:06] <robin_sz> the router has no trouble taking a plunge into 18mm ply .. 7hp gets the job done :)
[19:44:53] <jdhNC> the most annoying cut2d thing is that it won't cut a single line from a dxf
[19:45:20] <robin_sz> true
[19:45:25] <robin_sz> cut3d will though
[19:45:48] <robin_sz> we had exactly that issue
[19:46:05] <robin_sz> here was my last routing excercise
[19:46:07] <robin_sz> https://picasaweb.google.com/robin.szemeti/Solo
[19:48:08] <tjb1> Got my diy torch height control started :)
[19:51:08] <tjb1> Anyone use plasma cam?
[19:52:08] <skunkworks__> http://www.youtube.com/watch?v=IMUj0nmOt4A
[19:58:56] <MDesade> the eclipse has begun.. awesome sauce
[20:05:35] <r00t4rd3d> can you smell it?
[20:24:05] <tjb1> Is a 1/2-10 5-start have 2 turns per inch?
[20:24:08] <tjb1> *does a
[20:24:25] <ReadError> r00t4rd3d, cutting yet?
[20:35:03] <jymmm> solar eclipse
[20:35:12] <jymmm> now
[20:35:43] <jdhNC> cool. I can't see the sun
[20:36:04] <jymmm> =)
[20:37:21] <jdhNC> it has been dark for almost an hour though.
[20:40:31] <jymmm> I thin it's peeking now, brb
[20:41:24] <jymmm> almost
[20:43:31] <jymmm> JT-Shop: anonimasu 1LB $4 =) http://www.rutland.com/productinfo/black-furnace-cement.html
[20:45:22] <jdhNC> what do you do with that?
[20:48:29] <jymmm> make electric heaters
[20:50:03] <jymmm> jdhNC: I have around 100K of assorted gauges of Nichrome, going to use the cement to create a heating element for heat sealing plastic tubing
[20:50:10] <jymmm> 100K feet
[20:50:58] <tjb1> Got the initial height sensing done :D
[20:51:06] <jdhNC> that's a lot of wire for sealing a tube
[20:51:24] <pcw_home> neat eclipse. darkest I remember in the bay area
[20:51:27] <jymmm> jdhNC: Heh, it's really not that much as some of it is 36gauge
[20:51:44] <jymmm> pcw_home: yeah, waiting for it to peak
[20:52:04] <jymmm> jdhNC: I have some 40ga too
[20:52:09] <tjb1> http://pastebin.com/raw.php?i=10eeC4g2
[20:52:42] <pcw_home> really strange looking (Ive only seen one total eclipse :1979 in Washington)
[20:53:20] <jymmm> pcw_home: I only have UV goggles, so can't fully watch it
[20:54:30] <Tom_itx> it fell behind the trees but i saw a good part of it thru the welding goggles
[20:54:52] <pcw_home> just put a 1/8 hole in a piece of paper and look at the "pinhole camera" image
[20:55:15] <pcw_home> 1/8"
[20:55:24] <Tom_itx> yeah
[20:55:48] <Tom_itx> i think i've seen maybe 3 in my time
[20:56:41] <Tom_itx> one i recall, the birds went to roost
[21:02:01] <r00t4rd3d> ReadError, nope
[21:02:11] <pcw_home> The total eclipse I saw was stunning as the shadows cast by distant objects appeared razor sharp just before totality and at totality you could see the stars
[21:02:20] <jymmm> It's being sloooow
[21:03:07] <jymmm> had it been a full moon, it be over before you could snap the shutter =)
[21:09:49] <Aero-Tec> MDesade: so did you get your machine running?
[23:15:53] <Aero-Tec> dead here
[23:16:05] <Aero-Tec> any one home?
[23:16:06] <Aero-Tec> lol
[23:21:05] <MDesade> im back...
[23:21:32] <MDesade> i watched the eclipse, ate dinner, etc...
[23:21:54] <jdhNC> then loaded linuxcnc, got some p-port cables to teh breakout board and now everything is great!
[23:22:36] <Aero-Tec> MDesade: did you get your machine running?
[23:24:16] <Aero-Tec> jdhNC: what were you working on?
[23:25:16] <jdhNC> Aero: not me, I was being cruel and making fun of his easystepper/mach.
[23:25:52] <jdhNC> I did get my g0704 running and spindle control working.
[23:26:15] <Aero-Tec> I wish I knew if mine was fixed
[23:26:52] <Aero-Tec> spent a hour testing, look fixed, but has fooled me several time before
[23:27:01] <jdhNC> what problem?
[23:27:32] <Aero-Tec> will work great for some time, not one hiccup, then it will start again
[23:27:53] <Aero-Tec> motor growling in one direction only
[23:28:12] <jdhNC> brushes?
[23:28:15] <Aero-Tec> and loosing steps by the boat load
[23:28:19] <Aero-Tec> no
[23:28:22] <jdhNC> oh, stepper.
[23:28:25] <Aero-Tec> check them
[23:28:34] <Aero-Tec> servo
[23:28:43] <Aero-Tec> step and dir
[23:28:49] <jdhNC> servo loosing steps?
[23:28:49] <Aero-Tec> gecko drive
[23:28:55] <Aero-Tec> lol
[23:28:58] <Aero-Tec> yes
[23:29:14] <Aero-Tec> go figure
[23:29:35] <Aero-Tec> it would just loose steps but not fault
[23:29:47] <Aero-Tec> have no idea how that can happen
[23:30:00] <Aero-Tec> now if will fault out
[23:30:14] <Aero-Tec> guess I am fixing it?
[23:30:39] <jdhNC> did you swap drives/motors/pins and see if the problem followed it?
[23:30:55] <Aero-Tec> I have been changing grounds, moving power wire and such
[23:31:05] <Aero-Tec> I wish
[23:31:22] <Aero-Tec> it started like it was only one axis
[23:31:33] <Aero-Tec> but found out both will do it
[23:31:46] <Aero-Tec> and they some time act up together
[23:32:03] <Aero-Tec> some times on at a time
[23:33:04] <Aero-Tec> it can be running great and then one move growl, but the next a split sec later is fine, and it can be fine for a long time
[23:33:39] <Aero-Tec> or it can growl for a long time ether axis or both
[23:33:58] <Aero-Tec> but always when the dir sig is high
[23:34:08] <archivist> check signals with a scope to check if in spec
[23:34:13] <Aero-Tec> that is the only constant I can find
[23:34:20] <Aero-Tec> yes
[23:34:29] <Aero-Tec> did that
[23:34:36] <Aero-Tec> they look good
[23:34:57] <Aero-Tec> even when growling like hell the sigs look good
[23:34:59] <archivist> add pull up resistor to dir signal is it high enough etc
[23:35:04] <Aero-Tec> nice and solid
[23:35:29] <Aero-Tec> the encoder sigs are good when it is running good
[23:35:44] <archivist> looking right does not mean the right voltage
[23:36:38] <Aero-Tec> and horrible when growling
[23:36:56] <Aero-Tec> the sig levels look good
[23:37:26] <Aero-Tec> changed computers as still the same
[23:38:17] <archivist> what voltage, is it correct for the signal level specification, looking smooth is not the right answer
[23:39:09] <Aero-Tec> they should be 5 volt right?
[23:39:20] <Aero-Tec> or is it 3.3
[23:39:28] <Aero-Tec> or 3.6
[23:39:36] <Aero-Tec> I like the older stuff
[23:40:02] <Aero-Tec> there was a standard 5 volt and that was it
[23:40:09] <archivist> you would know what level if you looked in your drives manual
[23:40:15] <Aero-Tec> now days it is hard to tell
[23:40:24] <Valen> the wonderfull thing about standards
[23:40:28] <Valen> theres so many to choose from
[23:40:34] <Aero-Tec> lol
[23:40:35] <archivist> this tells me you have not checked
[23:40:57] <Aero-Tec> it looked to be 5 volts
[23:41:09] <Aero-Tec> but I did not check for sure
[23:41:24] <Aero-Tec> was using a x10 probe
[23:42:05] <MDesade> no, it isn't running as i couldn't get to frys to buy a couple parallel cables AND watch the eclipse
[23:42:08] <archivist> and is the setup time correct for the drive, time dir is set before the step is toggled
[23:42:14] <Aero-Tec> would have to work it out as my scope does not have on screen readouts
[23:42:55] <Aero-Tec> I got to get a better scope
[23:43:02] <Aero-Tec> hard to say
[23:43:07] <archivist> is the step signal wide enough for the minimum pulse period too
[23:43:15] <Aero-Tec> I did not look at the timing
[23:43:41] <archivist> all this you can do by learning to use ones scope and reading the drive manual
[23:44:23] <Aero-Tec> my scope is over 40 years old
[23:44:24] <archivist> one can check the screen calibration you dont need on screen display
[23:44:46] <Aero-Tec> 20 mhz
[23:44:54] <Aero-Tec> I know
[23:45:04] <Aero-Tec> got lazy
[23:45:14] <Valen> on screen readouts
[23:45:17] <Aero-Tec> it looked close
[23:45:34] <Valen> in my day we had to wait for the valves to wam up before the scope worked and we were HAPPY!
[23:45:38] <Valen> warm
[23:45:41] <jdhNC> I had an ancient tek 465b. it was huge.. sold it and got a cheap chinese color LCD that is much more useful for me.
[23:45:42] <Aero-Tec> I did not double check the voltage
[23:46:11] <Valen> mainly because i could skive off and read web comics while the scope warmed ;->
[23:46:44] <Aero-Tec> I had one of them at one time
[23:46:58] <Aero-Tec> man was it nice
[23:48:18] <Aero-Tec> it took awhile to warm up to spec, but nice display and nice delayed, it just worked very well
[23:48:45] <Aero-Tec> but you had to make sure the tubes were were good
[23:49:34] <Aero-Tec> got a old time philips one now, it was nice in its day, great for TV repair, that was what I used it for
[23:49:45] <MDesade> i STILL use a tek 2465BDV and i love the scope, tube or no tube
[23:50:21] <Valen> i have a 700mhz tek now
[23:50:27] <Valen> no storage though
[23:50:39] <Valen> that would make life too easy lol
[23:51:25] <MDesade> yeah, i could use some storage myself
[23:51:32] <Aero-Tec> but its controls and contacts are dirty or worn out, I have dumped a whack of contact cleaner into the controls and switches
[23:51:39] <MDesade> it does EVERYTHING else i need, but that
[23:52:26] <archivist> I got lucky on ebay and got a logic analyser frame that has scope cards in it, 8 chans
[23:52:41] <Aero-Tec> so voltage readings are not reliable, thus the getting laze reading it by counting the div of deflection
[23:53:11] <Aero-Tec> you read it and not sure if it is telling the truth or not
[23:53:20] <Aero-Tec> time for a new one for sure
[23:53:30] <archivist> use dvm to calibrate from a 5v supply
[23:53:49] <archivist> then you are sure
[23:54:21] <Aero-Tec> I wish
[23:54:54] <Aero-Tec> the contacts are wore out, they make and break
[23:55:14] <Aero-Tec> one sec it can be good but the next, not so much
[23:55:30] <archivist> clean, rotate back/forward till cleaned
[23:55:31] <alex4nder> yoh
[23:55:49] <Aero-Tec> I have tried
[23:56:05] <Aero-Tec> several times
[23:56:24] <Aero-Tec> poured the contact cleaner into it
[23:56:41] <Aero-Tec> worked it hard and still not so good
[23:57:16] <Aero-Tec> it did get better then what it was, but still not good
[23:58:02] <Aero-Tec> time got a good storage high speed one
[23:58:30] <Aero-Tec> my scope could be just to slow to see what up
[23:58:57] <Aero-Tec> 20 mhz for digital is to slow
[23:59:06] <archivist> 20 meg is fast enough
[23:59:21] <Aero-Tec> it is better then nothing
[23:59:29] <Aero-Tec> but you can miss things
[23:59:52] <Aero-Tec> transient spikes
