[01:13:39] <eric_unterhausen> well, my amd e350 has a really horrible way of handling booting from a usb disk, so that's a downside
[01:14:35] <eric_unterhausen> basically making me guess how to get it to boot from usb
[01:15:17] <eric_unterhausen> apparently common with gigabyte motherboards
[01:17:32] <uw> good old gigabyte
[01:19:39] <eric_unterhausen> too bad nobody mentioned this in the reveiws
[01:19:52] <eric_unterhausen> I think there may have even been a linuxcnc review on newegg
[01:20:24] <eric_unterhausen> have definitely seen it mentioned on there
[01:27:52] <CaptHindsight> eric_unterhausen: which BIOS and which MB is that?
[01:31:43] <CaptHindsight> http://www.youtube.com/watch?v=IntsDeX_s1M ASRock E350M1/USB3 has coreboot support
[01:31:44] <Tecan> (IntsDeX_s1M) "Coreboot - 9.6sec from poweron to XBMC" by "mjbuschman" is "People" - Length: 0:00:15
[01:33:51] <CaptHindsight> we are working with the A series APU's now, once we get xenomai, RT=PREEMPT and or RTAI working well with 3.8 kernels we'll go back and iron out any issues with the E series
[01:35:41] <CaptHindsight> the asrock board is getting old and will be difficult to get, so we'll probably get coreboot on some newer E series APU MB that is readily available
[01:38:59] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157228 still at newegg for $95
[01:44:19] <CaptHindsight> eric_unterhausen: ^^ coreboot http://www.asrock.com/mb/overview.asp?Model=E350M1 http://www.coreboot.org/ASRock_E350M1
[01:46:38] <DJ9DJ> moin
[01:49:07] <CaptHindsight> accelerated graphics drivers for the E or A series APU's are only in the 3.x kernels
[07:10:41] <R2E4> can anyone point me in the right direction for finding xml config file for pnconf for 5i25 and 7i77?
[07:11:04] <jthornton> the forum
[07:18:30] <Tom_itx> is that all those files are used for?
[07:19:42] <jthornton> yea pncconf uses them to know what pins are there
[07:20:18] <R2E4> Is there a section in the forums for files or just search the messages?
[07:20:20] <Tom_itx> i guess when you make a custom pin file you don't get one
[07:20:39] <Tom_itx> just man up and wing it without one
[07:21:24] <jthornton> there is a script in the pncconf section that downloads and installs the 5i25 xml files
[07:21:56] <jthornton> it's a sticky so it is at the top of the section
[07:22:16] <R2E4> yeah, I found it
[07:22:31] <R2E4> I have alot of manning up to do on this project.
[07:23:35] <Tom_itx> jthornton you know anybody refurbishing a series ii bridgeport i ran across some material on it while looking for something else last night
[07:23:49] <Tom_itx> schematics etc
[07:24:20] <R2E4> What drives are in the bridgeport?
[07:24:31] <jthornton> don't know of any
[07:24:47] <Tom_itx> i kinda hate to just pitch em
[07:25:10] <R2E4> I was going to retrofit mine but got all the original stuff working so I didnt have to.
[07:25:47] <R2E4> Series 1 R2E4 boss 9
[07:26:19] <Tom_itx> iirc this is series ii boss 5
[07:29:50] <R2E4> I am going to document step by step word by word and write a book. Coverting a Hitachi Seiki VM40 to LinuxCNC, and sell a million copies then i can retire.
[07:29:54] <R2E4> Thats the plan.
[07:40:30] <jdh> how much floor space does a vm40 take?
[07:41:31] <Tom_itx> it'll be in the book
[07:55:41] <R2E4> 6'X8'
[07:58:14] <jthornton> no doors on it?
[08:00:48] <jthornton> my 308 is about that big plus 2' on each side for doors and humans
[08:06:36] <jdh> my 308 has a 26" barrel
[08:12:36] <R2E4> There is the control which sticks out about 3foot on a swival arm
[08:12:50] <R2E4> The doors are sliding
[08:18:32] <R2E4> http://irmtl.com/vm40/schematics1.pdf
[08:19:09] <R2E4> Lots of other lines coming into the seico control I am replacing.Do I just not connect them to anything?
[08:19:49] <R2E4> The VCMDX/ECX, That I would presume is the 0-10v analog signal from the 7i77 to Servo amp. Thoughts?
[08:28:08] <DJ9DJ> re
[08:33:31] <Nick001> <Tom_itx>I'd be interested in those for my Boss 5 machine. Did you post them anywhere?
[08:48:01] <JT-Shop> R2E4: I don't recall off hand but that doesn't sound right...l the pin outs for each connector are in the 7i77 manual
[09:04:28] <R2E4> IT depends on which amps, i am pretty sure they are not the same as mine in the R2E4 boss9.
[09:05:07] <R2E4> Did you see igor's site with BP manuals?
[09:10:13] <JT-Shop> oh you mean on the servo amps...
[09:11:44] <R2E4> I think he was talking about the boss5 servo amps BP drawings
[09:12:53] <R2E4> The mesa boards and linuxCNC doesn't need the tachs?
[09:15:25] <JT-Shop> the tachs usually go to the drive and the encoder to the 7i77
[09:16:54] <R2E4> http://irmtl.com/vm40/schematics1A.pdf
[09:17:10] <R2E4> http://irmtl.com/vm40/schematics1.pdf
[09:17:27] <R2E4> THis shows the tach going to the seicos control
[09:18:58] <R2E4> AH, the tach looks like it is going to the drive. THen there is OP1 coder, no idea what that is.
[09:19:07] <JT-Shop> that's the encoder not the tacho
[09:19:43] <JT-Shop> Z is index and A and B are the quad
[09:20:08] <JT-Shop> G1 and GX1 should be 5v
[09:20:31] <JT-Shop> you might need to look at the encoder sticker to verify
[09:21:05] * JT-Shop goes to town for a couple screws :(
[09:21:26] <R2E4> 10.00 gas for 3.00 worth of screws?
[09:22:07] <R2E4> Would I need to find out what the servo alarm signal is if it can be connected to the mesa boards?
[09:25:06] <JT-Shop> $3 for gas $10 for screws LOL
[09:25:29] <R2E4> oh, so you can walk and save 3.00....lol
[09:29:57] <archivist> but then that delays the income on the objects the screws are for
[09:31:21] <R2E4> I'm beting there is more tolerance for the time than budget.
[09:31:27] <R2E4> betting
[09:31:57] <Tom_itx> Nick001, no i just have a folder here i ran across
[09:45:11] <Valen> sometimes its good just to leave the house
[10:05:37] <Tom_itx> Nick001, these are dated 1979-1980 and have tech bulletins for DNC, data communication, M-154 Maintenance Manual for the Series I CNC Boss 4, 4.1 & 5 controls with schematics, the Mdsf-139 Programming Manual for the Series II with Boss 6 software
[10:05:45] <Tom_itx> 2 binders
[10:07:19] <Tom_itx> i was planning to take them to the meet tomorrow to see if anyone wanted them
[10:08:06] <Tom_itx> s/Mdsf-139/M-139
[10:08:32] * archivist collects any manuals :)
[10:08:56] <Tom_itx> ^^ must have more space than me
[10:09:19] <archivist> send back in andypughs luggage if he does not mind :)
[10:09:35] <archivist> I do have a space problem
[10:09:35] <Tom_itx> i don't mind if he doesn't
[10:10:13] <archivist> I scan when I get requests http://www.collection.archivist.info/
[10:10:30] <Tom_itx> they might not be so useful if you're doing a conversion
[10:10:41] <Tom_itx> maybe nick will request you scan them :)
[10:11:19] <Tom_itx> the schematics are D size foldouts
[10:12:00] <archivist> one day I want to get a large format scanner, currently it is a stitching job
[10:12:04] <Tom_itx> also has photos with troubleshooting tips
[10:12:38] <Tom_itx> these were fitted with tape readers originally
[10:14:13] <archivist> I have thought of using linuxcnc as a microfiche scanner perhaps I should use it for large format too
[10:15:02] <Tom_itx> he might want to ditch the binders and just pack the paper material
[10:15:11] <Tom_itx> i'll take some envelopes along in case
[10:15:18] <archivist> thanks
[10:15:37] <Tom_itx> forewarn him if you see him
[10:16:19] <archivist> will do
[10:19:42] <archivist> if somebody states side needs them when you get there dont worry about me
[10:20:07] <Tom_itx> i just hated to throw them out
[10:20:16] <Tom_itx> but don't need em now
[10:20:31] <archivist> I hate throwing information too hence the collection :)
[10:21:46] <Tom_itx> as i recall you had to program 4 quadrant arcs on that control
[10:21:57] <archivist> I stated cataloguing for my own findind aid, put it on the web for me...users found it and odd things from the 50s through to the 80s get requested
[10:22:07] <archivist> started
[10:24:12] <Tom_L> here's one for JT-Shop http://www.electronicproducts.com/Sensors_and_Transducers/Sensors/Motorcycle_helmet_projects_GPS_directions_on_to_biker_s_vision_guard.aspx
[10:25:28] <cpresser> will there be an 'official' linuxcnc-fest in the forseeable future?
[10:25:43] <archivist> it is NOW
[10:26:05] * cpresser did read the forum, but it says its more developer centered!?
[10:26:06] <archivist> goto mpm today till weekend
[10:27:07] <Tom_itx> 2100 S West, hometown usa
[10:27:39] <cpresser> unfortunately i would neet to book a flight asap, which is way to expensive
[10:28:07] <cpresser> thats why i was asking for another meeting in the 'forseeable future' :)
[10:28:26] <Tom_itx> i used to ride side saddle with a ups flight mechanic from time to time
[10:28:47] <Tom_itx> just for a joy ride
[10:29:35] <cpresser> sounds fun. but also like a lot of trouble with us immigrations department :D
[10:33:35] <jdh> see whats' in PORN.zip first
[10:33:43] <jdh> <urk>
[10:35:16] <cpresser> the NSA knows about that file anyway^^
[10:42:32] <Tom_itx> this was waaay before 911
[10:52:12] <JT-Shop> http://imagebin.org/261992
[10:52:59] <PetefromTn> JT-Shop: Looks sweet man.
[10:53:06] <JT-Shop> thanks
[10:53:25] <JT-Shop> now for the other end of the encoder
[10:53:42] <PetefromTn> Ya gonna fab up a nice protective cover for it now?
[10:53:51] <JT-Shop> later
[10:54:07] <JT-Shop> got parts to make lol
[10:54:15] <PetefromTn> Nice...
[10:56:45] <micges> archivist: hi
[10:57:26] <micges> archivist: can you point me to some good used co2 lasers source in UK?
[11:14:15] <JT-Shop> if CW rotation on the spindle gives me -vel and -count just swap the A and B at the 7i77?
[11:14:35] <pcw_home> yes
[11:15:56] <JT-Shop> thanks
[11:17:36] <JT-Shop> index tested and works
[11:19:41] <R2E4> http://irmtl.com/vm40/schematics1.pdf
[11:20:24] <R2E4> the servo out and overheat out, is that usually voltage re: 5v or 0 on reset?
[11:21:41] <R2E4> pcw_home: do the encoders look like they should work?
[11:37:19] <pcw_home> encoder looks like a standard differential type so should be fine
[11:37:21] <pcw_home> No idea what the output signals are (unless you have a manual)
[11:37:22] <pcw_home> looks like theres an enable in
[11:37:44] <pcw_home> also no idea what enable in signal is required
[11:39:13] <JT-Shop> yuck there is no spindle rpm display in touchy that I can find
[11:51:07] * JT-Shop wonders if he can make some kind of pyvcp readout for actual rpm while touchy is running?
[11:52:09] <cradek> oh you don't mean command (I was sure it was there)
[11:52:41] <JT-Shop> yea commanded is there, but I need to adjust my vari speed to get what I want
[11:53:17] <JT-Shop> I've not converted to a timing belt drive yet
[11:54:11] <JT-Shop> so if I set the vari speed to 600 and command 900 I should get 300 rpm but I need to know what it is for the tappnig head
[11:54:48] <JT-Shop> kinda messed up way to run it I know, but it is what I have
[11:55:16] <cradek> just set it way too fast and start tapping - slow it down until it doesn't click so much
[11:56:55] <JT-Shop> hmm maybe halcmd halmeter -s pin motion.spindle-speed-in
[11:57:16] <cradek> halcmd loadusr
[11:57:25] <cradek> but yeah you could even put that in touchy.hal
[11:57:38] <cradek> I think you can add a panel ... somehow
[11:57:43] <cradek> it shows up on a new tab
[11:57:48] <JT-Shop> thanks
[11:58:10] <JT-Shop> I'll explore that a bit
[11:58:54] <cradek> should be in the docs somewhere :-)
[11:59:03] <JT-Shop> looking
[12:04:11] <IchGuckLive> hi all B)
[12:15:11] <IchGuckLive> Loetmichel: thunder today ?
[12:19:56] <jthornton> ah I found it mentioned in the GladeVCP manual
[12:20:41] <IchGuckLive> finding something is always a pleasure
[12:22:49] <Loetmichel> IchGuckLive: no thunder, but violent winds and some rain
[12:23:12] <Loetmichel> and cooler now, only 27,3°c outside at the moment ;-)
[12:23:37] <IchGuckLive> its supper hot here 15min of rain ans storm also we expect the next frontsystem at 21:00
[12:23:55] <IchGuckLive> http://www.wetter.com/wetter_aktuell/niederschlagsradar/deutschland/
[12:52:04] <archivist> micges, never bought or looked at lasers
[12:52:27] <Jymmm> me neither.
[12:52:31] <micges> I understand, thanks
[12:53:02] <Tecan> why does it have to be in uk
[12:53:10] <archivist> micges, you want cncbasher he does have some lasers
[12:53:32] <Tecan> ebay you can get power supply and tube 40 watt for 6-700 bux
[12:53:46] <Tecan> actually for 60 watt its 800
[12:53:56] <Tecan> that can do metal
[12:54:11] <Jymmm> Tecan: O_o
[12:54:18] <Tecan> just engraving
[12:54:25] <Jymmm> Nuh uh
[12:55:09] <micges> my customer bought used laser with broken control from UK
[12:55:17] <Jymmm> For a laser to mark/cut metal you would need in the neighborhood of a 2000W CO2 or a 50W YaG laser
[12:55:20] <micges> just searching starting point
[12:55:57] <micges> I need to cut plywood <8 mm
[12:56:10] <micges> so I think up to 120W
[12:56:23] <micges> archivist: I will ask
[12:56:32] <IchGuckLive> 60W is the money breaker
[12:56:39] <Jymmm> 50W YaG laser engraving titanium... http://i51.tinypic.com/2zfsqzd.jpg
[12:56:43] <IchGuckLive> above it will kill your pocket
[12:58:26] <archivist> micges, past his time on now
[12:58:35] <archivist> !seen cncbasher
[12:58:36] <the_wench> last seen in #linuxcnc 2013-06-20 17:29:37GMT 01:14:51 ago, saying joined chan
[12:58:47] <Jymmm> micges: to cut 8mm plywood you would prefer a 250W CO2, but could get away with a 140W
[12:59:03] <Jymmm> micges: happily that is.
[12:59:08] <micges> I know
[12:59:52] <Tecan> 8 mm plywood can be done on 40 watt easily
[12:59:57] <micges> amount of cutting material is quite low per day so it can be cut 2x slower
[13:00:29] <cpresser> you can cut 10mm plywood on a 80W laser@60% power with about 4mm/sec feed
[13:00:41] <cpresser> at least my machine works around those numbers
[13:01:01] <Jymmm> I said "happily".
[13:01:13] <Tecan> my focal point is about inch and a quarter away from peice
[13:01:27] <Tecan> cant remember what lense i bought
[13:01:30] <micges> cpresser: quite fast
[13:01:42] <micges> cpresser: pulse mode?
[13:02:05] <cpresser> micges: cant tell. its a el-cheapo chinese control. those menues dont have a translation
[13:02:21] <micges> ok
[13:02:24] * cpresser will do a linuxcnc-conversion as soon as i understand how to do rastering with hal-streamer :)
[13:03:34] <Jymmm> cpresser: Hmmmm, I never thought of that. lcnc can't do rastering, you sure?
[13:04:03] <cpresser> Jymmm: there is a hack for rastering available, let me google it...
[13:04:20] <Jymmm> cpresser: It's ok, no need. But I mean natively
[13:04:47] <cpresser> Jymmm: how would you do the CAM for that?
[13:05:08] <Jymmm> cpresser: bypass it and go straight for the paraport aspects ???
[13:05:18] <Jymmm> (printer)
[13:05:19] <cpresser> rastering means feeding a greyscale-image for intensity
[13:05:37] <Jymmm> cpresser: cradek has a iamge to gcode thing
[13:06:16] <Jymmm> http://timeguy.com/cradek/image-to-gcode
[13:06:37] <cpresser> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Rastering_With_A_Laser
[13:06:41] <pcw_home> wonder how many of those CO2 lasers get broken in shipping
[13:06:54] <Jymmm> pcw_home: the tubes? LOTS =)
[13:07:29] <Jymmm> cpresser: http://timeguy.com/cradek/image-to-gcode
[13:07:41] <cpresser> Jymmm: yep, i am taking a look at it right now
[13:07:47] <Jymmm> cpresser: k
[13:08:02] <micges> you could use image to gcode for rastering, just use Z as laser power
[13:08:24] <Jymmm> cpresser: (I know what you are saying, just never thought about it in LCNC =)
[13:08:28] <micges> and some ini setting combination to achieve quite constan velocity
[13:08:37] <cpresser> actually i like the hacklab-toronto approach more. because it has constant speed
[13:08:52] <cpresser> they use 'overscan' for accelleration of the axis
[13:09:55] <cpresser> but i am unsure how i can incorporate that into my cam. i want to have the image and the vectors in the same cam-window to align them
[13:10:01] <cpresser> i need to work out a process for that
[13:10:25] <Jymmm> cpresser: registration marks.
[13:10:56] <Jymmm> (in essense)
[13:11:13] <cpresser> good idea, i could use the different color-channels of a png for that
[13:11:25] <cpresser> eg. have red for the image, and green for the marks
[13:11:59] <Jymmm> cpresser: Kinda how I do stuff like this... http://i51.tinypic.com/2jttp2.jpg
[13:12:30] <Jymmm> cpresser: raster for the engaving, vector for the cutting.
[13:12:38] <cpresser> Jymmm: did you use image2gcode to raster this one?
[13:12:46] <Jymmm> cpresser: Heh, no.
[13:13:42] <cpresser> this was done with the chinese software: http://imagebin.org/262000
[13:14:10] <cpresser> (i failed to clean this one^^)
[13:14:11] <Jymmm> cpresser: I have a ULS M-300, it acts like a printer. Most everything I do is in CorelDraw, then "print" to the lasser.
[13:14:25] <Jymmm> cpresser: Where did you find the led base?
[13:14:32] <cpresser> yep, same here. i also use CorelDraw
[13:14:50] <cpresser> The base is a extrusion profile from the 'ITEM' company
[13:15:00] <Jymmm> cpresser: link?
[13:15:18] <cpresser> searching...
[13:15:42] <cpresser> http://www.item24.de/produkte/produktkatalog/produktdetails/products/flache-querschnitte-8/profil-8-40x16-e-natur-7000001.html
[13:16:00] <Jymmm> cpresser: shower handle?
[13:16:15] <cpresser> extrusion profile
[13:16:27] <cpresser> these are used for construction of machines
[13:16:35] <Jymmm> cpresser: Yeah, but meant for shower handle?
[13:16:54] <cpresser> i dont think so :)
[13:16:59] <Jymmm> cpresser: and the black gasket?
[13:17:37] <cpresser> also from that company.. let me get a number for that...
[13:17:42] <Jymmm> k
[13:17:59] <Jymmm> ~~~ LED Base
[13:18:55] <Jymmm> cpresser: How well does it stay in the base?
[13:19:26] <cpresser> its hard to remove it once its in
[13:19:32] * cpresser uses a press to mount it :)
[13:19:45] <cpresser> http://catalog.item24us.com/en/product_info.php?info=p43685_Lip-Seal-8-2-4mm--black.html&cat=1001012486
[13:20:17] <cpresser> http://catalog.item24us.com/en/product_info.php?info=p2679_Cap-8-40x16--black.html&cat=1001046502
[13:20:44] <cpresser> http://catalog.item24us.com/en/product_info.php?info=p7000001_Profile-8-40x16-E--natural.html
[13:20:51] <cpresser> those 3 parts make the base
[13:21:36] <cpresser> the acrylic is 6mm. if you use 5mm, its easier to mount and to remove, but for 6mm the fit is really tight :)
[13:22:23] <cpresser> it took me ages to find a system as a base that is this easy and cheap. building bases by yourself sucks compared to this
[13:24:38] <Jymmm> cpresser: Yeah, tell me about it. ESPECIALLY the end-caps. Why do you think I asked in the first place =)
[13:25:25] <Jymmm> cpresser: Yeah, fuck the sign... what is the base????" lol
[13:25:35] <archivist> he told you
[13:25:47] <Jymmm> archivist: It's a joke!, Note the quotations
[13:25:48] <archivist> gave all the parts
[13:26:19] <archivist> no quotes visible
[13:26:23] <Jymmm> archivist: and the LOL
[13:26:45] <Jymmm> archivist: Pull the stick out of your butt already
[13:29:51] <Jymmm> cpresser: Thanks, I'll have to see if I can fid the equiv here. I tried last year but they have 5000 extrusion prfiles but stopped providing the outlines in their catalogs 5 years ago.
[13:30:13] <cpresser> Jymmm: cou can get CAD on their webpage
[13:30:31] * cpresser uses those extrusion parts a lot for all different tasks
[13:31:08] <Jymmm> cpresser: what is their primary market?
[13:31:58] <cpresser> industrial
[13:32:11] <cpresser> those profiles are used to quick build machines
[13:32:12] <Jymmm> cpresser: A little more specific?
[13:32:36] <cpresser> Jymmm: sorry, thats where i need to look up words; english is not my native tongue :)
[13:32:45] <Jymmm> cpresser: Hmmmm, the closest I can think of here in the US is 80/20
[13:33:25] <cpresser> Jymmm: yes, that seems to be basically the same market
[13:33:53] <Jymmm> cpresser: I've been looking at shower/commercial railing supplier here. They have like over 2M products/parts
[13:35:00] <cpresser> Jymmm: i am quite sure 'item' also sells on the US market. but most likely you will get similar stuff from 80/20
[13:36:06] <cpresser> Jymmm: http://www.item24us.com/distributors in germany the ship their stuff; even the long 6m extrusions
[13:37:58] <Jymmm> cpresser: Oh, nice!!!! TYVM
[13:40:48] <Jymmm> cpresser: I had thought they were EU only
[13:41:28] <cpresser> Jymmm: nope, they are way to big for that :)
[13:43:55] <jdh> we have been getting bosch extrusion instead of 8020 lately
[13:45:40] <Jymmm> jdh: bosch being the same as 80/20 ?
[13:46:18] <jdh> same general idea, different product/company
[13:46:39] <Jymmm> gotcha
[13:48:23] <cpresser> funny. bosch is one of the largest german companys. i even worked there for about a year. but i didnt know they sell extrusions :)
[13:49:05] <archivist> looks like they bought rexroth
[13:49:31] <Loetmichel> cpresser: bosch is a bit like siemens
[13:49:55] <Loetmichel> a bank with attached electronics/mechanics trade ;-)
[13:50:05] <Jymmm> GAWD I LOVE IT.... I can now burn an iso directly! NAS --> LAN --> IMac --> USB_DVDR_DRIVE =)
[13:50:13] <archivist> GEC used to like that too
[13:50:37] <archivist> some banker screwed it up though
[14:02:41] <willburrrr2003> sorry, network crashed
[14:03:04] <willburrrr2003> missed any responses to my questions on pwmgen
[14:04:47] <willburrrr2003> The questions were 1) If my max spindle speed is 1250RPM , do I set pwmgen.0.scale 1250 ? 2) what determins pwmgen.0.pwm-freq value?
[14:07:41] <jdh> scale can be anything, mine is set to my max spindle speed. Freq depends on what you are driving with it
[14:08:47] <willburrrr2003> If i am understanding the example, I will be driving it with base thread?
[14:09:45] <jdh> if you are using p-port, it makes the pulses in the base-thread
[14:11:14] <willburrrr2003> jdh> yes I am using parallel port, and tying pwmgen.0.make-pulses to base-thread , so does that mean that my pwmgen.0.pwm-freq would be half of the value of the base thread frequency?
[14:12:03] <jdh> no, the freq is set to whatever the device you are drivign with it needs
[14:13:30] <jdh> actually. I don't know if that is true for p-port. I have only done it with a mesa
[14:14:48] <jdh> http://www.linuxcnc.org/docs/html/examples/spindle.html#_pwm_spindle_speed
[14:14:51] <jdh> there is no freq in the example that I see.
[14:15:49] <willburrrr2003> the example i am lookng at on the wiki is http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Closed_Loop_Spindle_Speed_Control
[14:18:59] <jdh> I set my freq. to match what my cnc4pc pwm->analog board wanted.
[14:21:40] <willburrrr2003> ahh, are you using the c6 board also?
[14:23:23] <jdh> C41 I think
[14:24:09] <jdh> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=303
[14:25:22] <willburrrr2003> I used the c6 board, and have been driving it with stepgen in an openloop config, and had stepgen freq set at 25khz to get the full speed output voltage of my c6 (4.6vdc per my speed controller on my lathe) which is at 1250 RPM
[14:26:12] <willburrrr2003> Now I am adding closed loop speed control with PID control as well, so changing from stepgen controlling the spindle to using pwmgen
[14:26:31] <willburrrr2003> finding out there is a lot to wrap my brain around lol
[14:26:39] <jdh> I think, but do not know, that you will have problems doing that with the C6.
[14:28:55] <willburrrr2003> what makes you think that? It is made to accept a PWM signal to drive it , and outputs a 0-10v (scaled down for my lathe to 0-4.6vdc) signal that my lathe speed controller runs on...and drives it nicely so far, but I do not have feedback yet(reason for upgrade) to see if I am running at commanded speed as well as threading and css, etc
[14:29:53] <jdh> easy enough to check. Set it up as open loop pwmgen and see if it works
[14:30:23] <jdh> does the c6 do freq, or pwm input?
[14:30:31] <willburrrr2003> PWM input
[14:31:05] <jdh> are you sure? I woudl think that if you ran it via a stepgen, it woudl only be seeing frequency?
[14:32:06] <jdh> nputs a frequency (step) and
[14:32:06] <jdh> outputs an analog 0-10VDC
[14:32:26] * JT-Shop is fixing to test if G95 works with the drill cycle
[14:32:48] <willburrrr2003> ahhhhh, just re-read it....you are correct it accepts a freq input...which explains why a year ago I set it up being driven with thepgen... so that means to keep using the board, I need to keep stepgen instead of using pwmgen....
[14:33:06] <uw> wilburrrrr
[14:33:16] <jdh> can you make it a closed-loop stepgen?
[14:34:43] <willburrrr2003> yes I can do that, using the encoder module, and a PID module... I think it will still work fine in that config. encoder give RPM, rpm signal drives the PID Loop, and corrects the stepgen freq to adjust speed to commanded value
[14:37:00] <JT-Shop> oh, I think I better use G85 for the tapping head
[14:38:37] <willburrrr2003> jdh> I think I have come out of this discussion with a better understanding of what I need to do, and also why I did what I did to drive my c6 speed control board when I set it up a year ago lol
[14:39:06] <willburrrr2003> Thanks, I appreciate bouncing thoughts off your brain, and the helpful feedback/input
[15:00:29] <willburrrr2003> well all, back to work... I will let you know how the mods go
[15:16:09] <JT-Shop> Cool, tapping with the tapping head is easier than I thought with encoder feedback and G95
[15:18:43] <Jymmm> JT-Shop: tap size?
[15:18:56] <JT-Shop> M5 x 0.8
[15:19:03] <Jymmm> nice
[15:20:15] <JT-Shop> I was lucky to put enought R in the boring cycle to retract the tap out before it moves to the next hole! The spring loaded mechanics take quite a bit of movement to reverse...
[15:20:32] <JT-Shop> I had forgotton about that
[15:21:12] <jdh> with a tapping head?
[15:21:30] <jdh> oh, that's what you said... I thought I saw rigid somewhere
[15:21:31] <JT-Shop> aye a Tapmatic
[15:22:24] <JT-Shop> no, not till I replace the vari-speed drive with a fixed drive will I try rigid tapping
[15:23:16] <JT-Shop> I'm just so happy to get the encoder mounted on the spindle!
[15:30:29] <Tom_itx> yay
[15:31:49] <syyl> tapping under machine power is one of the nicer things :D
[15:31:58] <syyl> no more crapy handtapping
[16:11:59] <DJ9DJ> gn8
[16:22:11] <JT-Shop> and the threads are straight too
[16:49:35] <Jymmm> JT-Shop: see what you can do when you're not sniffing the tractor fumes
[17:29:35] <Tom_itx> is the 7i68 a smaller version of the 7i84 without the field power option?
[17:30:48] <Tom_itx> mmm i thought i had an idea and looking further i see it's been done already... a sserial driven pendant card with the 7i73

[17:38:44] <PCW> 7I69 is a TTL level input/output sserial card
[17:39:37] <Tom_itx> is the pendant card fairly new?
[17:39:41] <PCW> I think the 7I69 has MPG inputs but the 7I73 is more designed for that (pendant) task
[17:39:59] <PCW> no its pretty old
[17:41:55] <Tom_itx> what's it's onboard regulator for?
[17:42:13] <Tom_itx> if io is powered via the sserial in
[17:47:56] <PCW> it gets its power from the serial cable 5V (but card power is 3.3V)
[18:24:39] <Tom_itx> it's tempting to have you bring one of those along
[18:24:54] <JT-Shop> yea, a fabricating job
[18:24:57] <Tom_itx> probably a little late in the game for that now though
[18:27:49] <PCW> well since I will get their late tomorrow its probaby too late
[18:28:27] <Tom_itx> are they meeting sunday as well?
[18:28:53] <Tom_itx> the note said the 17th - 23rd
[18:31:09] <Tom_itx> if i get back from KC in time i could swing by then for a bit possibly
[18:34:42] <Tom_itx> i shouldn't count on that since i'm not sure i'll be back
[18:54:13] <Jymmm> Hmmmm, kinda interesting as an 80/20 alternative http://www.youtube.com/watch?v=wHB9kg6CVpI&feature=player_embedded

[20:52:39] <Connor> just got back in town from a biz trip from Nashville
[20:54:05] <PetefromTn_> Cool.
[20:55:00] <PetefromTn_> Just got back from eating some messican food with the family. Picked up a new wireless keyboard and mouse for the desktop I setup to do cad cam works stuff
[20:55:45] <Connor> Cool. it running any better>
[20:55:46] <Connor> ?
[20:55:56] <PetefromTn_> yup TONS...
[20:56:15] <PetefromTn_> Had to clear everything with reg cleaners and spybot everything dammit
[20:56:59] <PetefromTn_> Right now I am drawing a cool aux spindle mount for my Porter cable router so I can do some high speed engraving without taxing the mills spindle too much.
[20:59:19] <Connor> Cool. I think I'm going to go get something to drink and eat some dinner.. been a LONG day.
[20:59:26] <PetefromTn_> http://snag.gy/qKD2S.jpg
[20:59:43] <Connor> Cool
[20:59:44] <PetefromTn_> Cool man...I got this big hunka 1" aluminum for the project
[20:59:59] <Connor> nice.
[21:00:01] <PetefromTn_> enjoy dinner
[22:57:31] <Aero-Tec> dead here
[22:57:41] <Aero-Tec> where is every one?
[22:58:45] <Tom_itx> at the pub after the fest today
[23:02:12] <toastyde1th> ha
[23:42:46] <RyanS> What is designed to inject oil into these tiny nozzles? http://www.lathespares.co.uk/index.php?main_page=popup_image_additional&pID=626&pic=0&products_image_large_additional=images/large/2012_09060036_01_LRG.jpg the only thing I can think of is a hypodermic needle
[23:48:42] <Valen> RyanS: standard oil can
[23:53:18] <RyanS> hmm, these nozzles are simply a tube with a small ball bearing to keep dirt out? Not like those drip oilers which store a certain volume of oil
[23:59:01] <toastyde1th> a lot of small lathes don't have much of an oil resivoir
[23:59:42] <toastyde1th> they don't really need a big thing of waylube, it's really viscous and doesn't drain quickly
