[11:20:37] <skunkworks> commutator http://electronicsam.com/images/Mazak/comu.JPG
[11:21:02] <archivist> may need cleaning :)
[11:22:23] <skunkworks> you see on the left side - they came delaminated..
[11:22:29] <skunkworks> *right
[11:23:11] <archivist> yes can see, time for a new armature/ complete motor
[11:23:30] <archivist> or loads of money on a rewind
[11:28:00] <pcw_home> Wow that looks nasty
[11:28:39] <pcw_home> coolant contamination?
[11:30:58] <skunkworks> or just replace it with a similar sized one... :) -
[11:31:42] <pcw_home> yeah I would say that's fully depreciated
[11:42:23] <kwallace2> On the other hand, anything that can be made can be repaired, given enough time and money. These guys might know how to fix it: http://www.go-ev.com/Albums/WarP_Motor_Album_files/Components/index4.html
[11:45:43] <pcw_home> Sure but much cheaper to just replaced
[11:45:44] <pcw_home> (My father worked at a motor rewinding company what I was a kid, they could pretty much start with a frame and rebuild everything)
[11:45:55] <pcw_home> when I was
[11:48:47] <skunkworks> yah - servos are cheap.
[11:52:54] <kwallace2> Well don't throw the old one away.
[11:53:34] <pcw_home> Last thing they would do on a rewind was drill holes for a " Rewound by California Electric" name plate
[11:53:35] <pcw_home> and some joker would say: Hey, is that copper coming out of that hole?
[12:15:39] <kwallace2> I need to rewind this generator rotor, but copper magnet wire is too expensive: http://www.wallacecompany.com/machine_shop/Onan_5CCK/dcp_6664-1a.jpg . I have no idea how manufactures can sell a cheap generator for about the same price as the copper for a rewind.
[12:28:04] <Tom_itx> maybe they get better bulk prices
[12:28:25] <archivist> like in china
[12:28:52] <CaptHindsight> https://www.apm.com/products/data-center/x-gene-family/x-c1-development-kits/x-c1-development-kit-basic/ first ARM64 dev board $896
[12:28:53] <Tom_itx> that may not be real copper
[12:31:04] <CaptHindsight> I've been given mystery metals in China and India that were supposedly copper or aluminim
[12:31:13] <CaptHindsight> the aluminum would not anodize
[12:31:34] <CaptHindsight> and the copper was a bit less conductive than expected
[12:32:04] <CaptHindsight> so yeah, they sell melted scrap that hasn't been refined
[12:35:28] <Tom_itx> i even question products coming from there with the ISO9xxx approval on them
[12:43:51] <pcw_home> First result we saw of assembly contractors changing to IS0900x was instant drop in quality
[12:45:31] <archivist> I have just seen people attempt to get ISO9000 and be fleeced by the consultants
[13:00:53] <Tom_itx> it's just a paper trail anyway
[13:01:13] <Tom_itx> blaming that poor sob on the assembly line
[13:30:03] <skunkworks> https://github.com/machinekit/machinekit/issues/396
[13:33:34] <archivist> he is forgetting those multi jointed arms that can get to one place with the joints in different positions probably
[13:37:41] <skunkworks> a bit above my head..
[13:52:22] <skunkworks> http://www.machsupport.com/forum/index.php/topic,28439.msg199855.html#msg199855
[13:52:46] <skunkworks> 'Mach4, in it's current state, is much harder to setup than Mach3, and customization is far more complex. The support requests are going to go through the roof.
[13:52:47] <skunkworks> On the plus side, I might be able to make a considerable amount of money if there's a way to make it easier for people to use Mach4. But again, support might be a serious issue here.'
[14:18:32] <Tom_itx> wouldn't it just be easier to sway them toward linuxcnc? :)
[14:19:20] <skunkworks> A few post up he compared it to linuxcnc.. (can't do anyting without programming...) whatever.
[14:19:31] <Tom_itx> haha
[14:19:50] <Tom_itx> he probably want's someone to write his gcode for him too
[14:20:32] <Tom_itx> maybe he should go buy a haas and a programmer to go with it
[14:20:32] <skunkworks> 'You are NOW speaking EMCism, If you want it you have to learn to program it or do without.'
[14:21:51] <Tom_itx> i'd have said Mori Seki but those are probably too good for him

[18:11:19] <Tom_itx> pcw_home, do you know how i go about uploading those pages to the wiki?
[18:11:52] <Tom_itx> and how to add to the table of contents..
[18:11:54] <pcw_home> no i dont
[18:12:12] <Tom_itx> me either but i think i've got them formatted ok for it now
[18:12:51] <Tom_itx> i don't wanna stick em in the wrong place..
[18:14:07] <atom1> well there is a 'basic steps' page for adding to the wiki...
[19:12:57] <Tom_itx> i should wait for advice i think
[19:26:09] <Tom_itx> pcw_home what would be a good menu title for those pages?
[19:26:32] <Tom_itx> apparently you can't edit that once created
[19:32:24] <kwallace2> It's pretty easy, or rather limited in what can be done. There is a sandbox that you can play in, which is a fake page that you can't hurt. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SandBox
[19:32:44] <Tom_itx> i have .jpgs i want to include
[19:32:47] <Tom_itx> how do you do that?
[19:33:04] <Tom_itx> does everything you upload go to the same folder?
[19:33:23] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php
[19:33:27] <Tom_itx> i want to move that to the wiki
[19:33:59] <Tom_itx> and add it to the table of contents
[19:34:54] <kwallace2> As far as I know, you can add text and pictures but not the same text format and colors and such.
[19:35:16] <Tom_itx> that was generated with asciidoc
[19:35:28] <Tom_itx> same as the regular docs i think
[19:36:49] <Tom_itx> if i create a menu item on the table of contents will it create a blank page for it?
[19:37:07] <Tom_itx> then i can upload the text to that
[19:37:20] <kwallace2> There are header formats so you can make some text bold or larger but that's about it. A header might go like -> == My Header ==
[19:37:51] <atom1> similar to asciidoc
[19:38:02] <atom1> <-tomitx
[19:38:46] <kwallace2> If you create a link on an existing page, it will create the empty page for you and you can start editing it.
[19:39:27] <kwallace2> Sorry, I gotta go to dinner.
[19:39:32] <atom1> i added an external link for now on the links page
[19:46:07] <Tom_itx> pcw_home, under tutorials: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tutorials
[19:46:21] <Tom_itx> just links
[19:46:32] <Tom_itx> i'll try to add a page later
[20:25:50] <pcw_home> Thats great!
[20:29:11] <Tom_itx> been looking over some of the format.. i may try it
[20:29:25] <Tom_itx> pcw_home, where should i add it on the table of contents?
[20:31:13] <pcw_home> You mean the link to the tutorials links?
[20:31:27] <atom1> the main wiki table of contents
[20:31:46] <atom1> http://wiki.linuxcnc.org/cgi-bin/wiki.pl
[20:32:03] <atom1> i'm gonna try to upload the page
[20:33:39] <atom1> there's 'configuring linuxcnc -> advanced configuration
[20:33:42] <atom1> maybe?
[20:36:13] <atom1> i'm not moving the link i just made... was gonna add the page as part of the wiki
[20:38:17] <pcw_home> hmm big improvement in hm2_eth latency by setting Ethernet IRQ priority higher than any other IRQ
[20:38:18] <pcw_home> Not surprising I guess but maybe masked on CPUs that have too small a cache
[20:43:09] <kwallace1> pcw_home, do you know offhand how fast a 5i25 encoder counter is? I have a 10k spindle that I'd like to mount an encoder disk on to and I'm trying to decide the ppr of the disk. Although, I should be able to throw out the high end if I only need rigid tapping.
[20:43:24] <atom1> i think i'll make a bullet 'MESA Bitfile Configuration' if that's ok with you?
[20:43:58] <atom1> and insert pages under that
[20:45:43] <pcw_home> non muxed encoders on a 5i25 can count up to about 16 MHz
[20:46:18] <pcw_home> (filter off)
[20:46:19] <pcw_home> about 3 MHz filter on
[20:47:01] <kwallace1> Even with the filter on I could do 100 ppr at 10k RPM, no problem.
[20:47:53] <pcw_home> Yeah usually for high res encoders the encoder itself is the limitation
[20:48:23] <pcw_home> (many have a a 300 KHz or so max output frequency)
[20:51:05] <kwallace1> I was planning on using Allegro tooth sensors. AT667 (?) I'll have to look up the datasheet.
[20:52:42] <kwallace1> Hmm, 20kHz
[20:53:22] <kwallace1> Oops, wrong number.
[21:46:41] <atom1> pcw_home, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Editing_MESA_Bitfiles
[21:50:49] <atom1> from the table of contents-> Advanced Configuration -> MESA Bitfile Configuration
[21:51:33] <atom1> working on the older spartan2 ver
[22:34:48] <KimK> pcw_home: Hi Peter, is there more info available on "...The sserial_port_0=0XXX configuration string..." mentioned here: http://www.linuxcnc.org/docs/html/drivers/hostmot2.html#_sserial_configuration I've checked the 5i22, 7i44, and 7i69 manuals, and if it's there, I'm not seeing it. There's only a brief mention near the end of the 7i69 manual, on p.44.
[22:37:20] <pcw_home> Its in the hostmot2 manual
[22:37:59] <KimK> Ah, OK, I'll look there, thanks.
[22:43:17] <atom1> pcw_home, they're both on the wiki page now
[22:44:49] <Tom_itx> pcw_home, if you notice any errors lemme know.
[22:48:05] <pcw_home> OK I'll take a look
