[00:15:00] <R2E4_> evening....
[00:25:40] <KimK> jesseg: An arc as you might draw it or as you might program it in gcode?
[02:19:23] <Deejay> moin
[08:12:43] <JT-Shop> morning
[08:20:11] <skunkworks__> good morning - TGIF
[08:20:26] <skunkworks__> happy valentines day!
[09:03:06] <PetefromTn> Morning Folks.
[09:19:43] <JT-Shop> oh crap, it's valentines day
[09:19:52] * JT-Shop looks for a Thompson
[09:23:17] <PetefromTn> Yeah I thought yesterday was Valentine's day and ran out last night for Flowers and Candy and a gift LOL...
[09:23:50] <pcw_home> better early than late...
[09:25:53] <PetefromTn> yeppers. Especially for that don't want to be in Dog house hehe
[09:42:55] <MattyMatt> to hell with valentine's when's pancake day?
[09:44:31] <MattyMatt> ah not for weeks, late easter this year
[09:45:26] <archivist> bah humbug, never had pancakes on pancake day last year
[09:46:03] <Valen> wifey is giving me valentines presents this year
[09:46:06] <Valen> I win!
[09:46:13] <Valen> pizza + beer + desert
[09:47:29] <PetefromTn> We do have a GREAT pancake place here in east Tennessee. It is called the Pancake Pantry in Gatlinburgh Tn. Awesome atmosphere and food.
[09:47:29] <MattyMatt> I can have that every night. winner is me
[09:59:36] <jdh> Pete: on the corner, halfway up the hill?
[10:03:22] <PetefromTn> The Pancake Pantry is right in the middle of the strip just down from the Ripleys aquarium and mexican restaurant , Maybe a couple hundred yards from the Hard Rock cafe on the other side of the street.
[10:04:02] <PetefromTn> Hard to miss it really...
http://www.pancakepantry.com/
[10:04:41] <PetefromTn> I love that place and they make taffee next door with old school taffy pullers you can watch during the nice weather.
[10:06:01] <PetefromTn> Before I sold my last Fiero we had a run up there into the mountains down thru the Great Smoky Mountains National park and stopped and ate there for breakfast. Then Had lunch in Townsend.
[10:12:24] <jdh> the one I was thinking of was up the strip, then that road that road that turns left
[10:16:06] <CaptHindsight> is there a repo of ini files somewhere?
[10:16:56] <PetefromTn> The Pancake Pantry is THE pancake restaurant in Gatlinburgh and as you can see from that website is the grand daddy of them all been there forever. You should see the inside of that place it is a woodworkers dream. I try to take my wife up there once in awhile to enjoy it and they make some great food.
[10:17:21] <jdh> pancakes == flat round death.
[10:21:12] <CaptHindsight> O
[10:21:23] <PetefromTn> really? I love pancakes, They also make of course Waffles, and about any sort of Breakfast item you can think of including some great crepes...
[10:21:53] <jdh> 1 pancake + butter & syrup is like 350 calories
[10:22:09] <jdh> and eating just one would be kind of silly after going out
[10:23:59] <archivist> 1 strange person....6 more like :)
[10:29:13] <CaptHindsight> new Mesa store?!
http://store.mesanet.com/index.php?route=product/product&product_id=58
[10:29:24] <CaptHindsight> or have I just been out of the loop?
[10:30:21] <CaptHindsight> I love the new site
[10:30:48] <archivist> yyou have been asleep
[10:31:27] <CaptHindsight> it's the first time it came up in a search
[10:32:47] <CaptHindsight> if you could search by bus/interface type or also by what connects to each other it would be even better!
[10:35:17] <CaptHindsight> but the links to the manuals and software/firmware aren't with the products
[10:37:32] <pcw_home> They should be. let me see about adding them
[10:38:25] <CaptHindsight> it's so much easier to navigate
[10:39:48] <pcw_home> I hadn't even looked, Lily and Oleg deal with the store, not me
[10:40:23] <PetefromTn> Looks the same to me....is it changed somehow?
[10:40:43] <PetefromTn> jdh: Yeah it is caloric intake at its finest LOL...
[10:40:51] <CaptHindsight> the light blue text on the grey background is a hard to see, but I'm in a really high res mode
[10:41:37] <CaptHindsight> PetefromTn:
http://mesanet.com/newparallelcardinfo.html vs new
http://store.mesanet.com/index.php?route=product/category&path=68_61
[10:42:02] <PetefromTn> Huh nice..
[10:43:50] <pcw_home> We are going to change the light blue also
[10:44:08] <CaptHindsight> looks like a wip
[10:46:57] <PetefromTn> Honeslty I really like websites with grey or dark grey backgrounds they are easier on the eyes and most stuff stands out better. I have my Quassel IRC client setup that way and it is nice.
[10:47:06] <PetefromTn> Kinda like this one...
http://yorik.uncreated.net/guestblog.php?2014=19
[10:47:43] <CaptHindsight> like it's 1999 :)
[10:48:15] <skunkworks__> I like black on black
[10:48:29] <CaptHindsight> a good graphic designer makes whatever scheme work
[10:48:54] <PetefromTn> Looks pretty modern to me man..
[10:48:54] <CaptHindsight> unfortunately some web devs have never taken a color theory class
[10:49:32] <CaptHindsight> http://www.additive3d.com/home.htm this one looks 10+ years old
[10:49:41] <PetefromTn> Reminds me of Blender which is also nice and pleasing to look at.
[10:49:57] <PetefromTn> Yeah that looks old..
[10:50:17] <CaptHindsight> yes, like Blender, it was what I first thought of
[10:53:20] <tehcereal> I've seen that people mill aluminium with the shapeoko that is using nema17 motors i think
[10:53:48] <tehcereal> is it posible to mill aluminium with that steppers?
[10:53:48] <eric_unterhausen> that could get tiresome really quickly
[10:54:04] <tehcereal> they had the problem with backlash
[10:54:27] <eric_unterhausen> not really backlash, drive compliance
[10:54:51] <CaptHindsight> backlash would be in the mechanics, they probably had issues with missed steps due to not enough torque
[10:55:43] <tehcereal> what would be good enough torque for aluminium milling :D
[10:55:52] <tehcereal> i dont need super speed
[10:56:38] <tehcereal> this semester we build a small cnc plotter
[10:56:49] <tehcereal> that got me interested in cnc stuff
[10:57:31] <tehcereal> so im looking to build a maschine capable of milling aluminium
[10:57:32] <tehcereal> :D
[10:58:58] <tehcereal> some nema23 motors maybe?
[11:00:59] <archivist> with the right gearing you could use almost any size, not enough information
[11:02:40] <tehcereal> what do people usually use for homemade aluminium mills?
[11:02:51] <CaptHindsight> nema23
[11:03:10] <CaptHindsight> unless they are really big mills then the next size up
[11:03:15] <tehcereal> :D
[11:03:36] <CaptHindsight> but shaponko's are small
[11:03:47] <CaptHindsight> http://www.shapeoko.com/
[11:03:47] <tehcereal> they use nema17 i thinnk
[11:04:11] <tehcereal> i was considerin to build first 3 axis cnc then upgrade it to 4 axis
[11:04:52] <archivist> when you get to 4 you really miss the 5th :)
[11:05:07] <zeeshan> lol
[11:05:21] <zeeshan> why is it that when i google for linuxcnc questions
[11:05:31] <zeeshan> andy pugh's posts pop up always
[11:05:38] <eric_unterhausen> he's the only helpful person
[11:05:54] <zeeshan> hes famous!
[11:05:54] <zeeshan> :P
[11:05:57] <eric_unterhausen> the rest of us are Mach employees trying to sow confusion
[11:06:07] <CaptHindsight> they have a nema23 z-axis kit
[11:06:26] <eric_unterhausen> I think it will take nema 23 on all axes
[11:06:36] <tehcereal> http://hackaday.com/2014/02/12/4-axis-delta-router-says-hello-world/
[11:06:37] <eric_unterhausen> originally, it wouldn't take 23 on the z
[11:06:53] <CaptHindsight> the rest of us mostly just answer questions here, so there's no google search results
[11:06:57] <CaptHindsight> just NSA
[11:07:03] <archivist> ouch that shapeoko looks a flimsy machine
[11:07:17] <tehcereal> this is what get me thinking to build a cnc myself
[11:07:24] <CaptHindsight> yeah, it's a toy to play with
[11:07:25] <eric_unterhausen> ya, NSA guys are going, "that Capt hindsight really nkows his stuff"
[11:07:30] <zeeshan> archivist: most diy machines are flimsy ;D
[11:07:52] <tehcereal> but i will build a "classic" frame not delta
[11:07:54] <eric_unterhausen> not really, go look at cnczone for many counter-examples
[11:08:00] <archivist> mine has some solid meaty bits
[11:08:17] <zeeshan> archivist: how much does it weigh
[11:08:19] <eric_unterhausen> my diy machine weighs 5500 lbs
[11:08:26] <CaptHindsight> eric_u_cnc: or "Detain at next Immagration crossing"
[11:08:37] <zeeshan> eric_unterhausen: you built even the metal bits?
[11:08:51] <eric_unterhausen> from the Indian grad students I know, that's the same thing as saying they know what they are doing
[11:08:53] <zeeshan> most diy machines don't weigh more than 200lb
[11:08:56] <archivist> zeeshan, never weighed it but has to be taken to bits to move
[11:09:21] <eric_unterhausen> zeeshan, no, that's my mill
[11:09:40] <zeeshan> i'm not talking about retrofits ;D
[11:09:45] <CaptHindsight> http://docs.shapeoko.com/
[11:09:51] <zeeshan> im talking about from the scratch buidls
[11:10:10] <zeeshan> where people make their own routers or 'bots' from scratch
[11:10:16] <archivist> mine is from scrap not scratch
[11:10:28] <eric_unterhausen> a bridgeport series 1 is barely rigid enough to mill steel at productive rates of speed
[11:10:46] <zeeshan> eric_unterhausen: most hobbiest don't need to be running at production speed rates
[11:11:05] <eric_unterhausen> most of us run at the max speed we can get away with
[11:11:38] <zeeshan> the people that need production speed rates
[11:11:50] <zeeshan> go buy a new machine from matsuura, mazak
[11:11:51] <zeeshan> ;p
[11:11:58] <eric_unterhausen> of course, most of my machining is at work when I should be doing something else
[11:12:18] <eric_unterhausen> but the backlog at the machinist is too much, so to get something done I need to do it myself.
[11:13:56] <zeeshan> have any of you guys messed around with accelerometers
[11:14:41] <zeeshan> or a load cell
[11:17:29] <CaptHindsight> that shaponko mill is mostly makerslide and light aluminum plate
[11:18:58] <CaptHindsight> anything beyond light gauge materials and it's not going to do well
[11:19:35] <CaptHindsight> there are vinyl cutters with stronger frames
[11:19:49] <tehcereal> yep
[11:20:30] <CaptHindsight> I just built some small lead screw positioners from scratch
[11:21:43] <CaptHindsight> 1/4" 6061 plate, 1/4-20 lead, 8mm rails, anything heavy (few kilos) and it flexes all over the place
[11:22:40] <zeeshan> ;]
[11:22:50] <PetefromTn> LOL yeah that is gonna be pretty damn light duty..
[11:22:57] <zeeshan> plasma cut with it!
[11:22:58] <zeeshan> ;p
[11:23:10] <CaptHindsight> it's for non-contact printing
[11:23:12] <PetefromTn> The torch may be too heavy heheh
[11:23:23] <CaptHindsight> few oz load
[11:25:14] <CaptHindsight> only 8" travel and it's pushing it for flex
[11:25:27] <zeeshan> time to work on the cnc controller
[11:26:05] <CaptHindsight> all that makerslide and 1" t-slot is pretty flimsy
[11:26:36] <CaptHindsight> even 8020 lists it under decorative applications vs anything mechanical
[11:31:08] <Connor> pcw_home: what's the 5i70, 5i71, and 6i71 for ?
[11:45:31] <CaptHindsight> 5i70 is a bridge from PCI to PCIe cable
[11:47:34] <CaptHindsight> 6i71 is a PCIe extender
[11:48:14] <Connor> I read that.. just wasn't sure what application that would be needed..
[11:48:26] <CaptHindsight> Connor: so you can extend the PCI/PCIe bus seberal feet
[11:48:29] <CaptHindsight> several
[11:48:45] <CaptHindsight> so PC in one room and PCI card in another
[11:49:21] <CaptHindsight> or at opposite ends of a large machine, <7m
[11:49:58] <CaptHindsight> some laptops even have PCIe ports
[12:07:39] <IchGuckLive> hi all B)
[12:07:59] <jdh> sup d00d
[12:09:53] <PetefromTn> Hey Ich..
[12:10:15] <IchGuckLive> ;-)
[12:25:17] <zeeshan> IchGuckLive: you guys are kicking canadian ass
[12:25:30] <IchGuckLive> ;-)
[12:25:40] <zeeshan> dont worry
[12:25:44] <zeeshan> it will turn soon ;D
[12:25:49] <IchGuckLive> our next gold medal man got a car accident today
[12:25:59] <zeeshan> doh
[12:32:33] <CaptHindsight> I'm trying to follow this guide for Ubuntu with EMC
https://sites.google.com/site/andrewscnc/home/mesa5i25
[12:34:20] <CaptHindsight> cmorely has updated his pncconf that allows selection of the 5i25 and 7i76
[12:34:28] <IchGuckLive> CaptHindsight: i got now 10 5i25 in use
[12:34:47] <IchGuckLive> with 7i76 !
[12:35:43] <CaptHindsight> looks like the installer doesn't create /lib/firmware/5i25
[12:35:44] <IchGuckLive> CaptHindsight: did you do the update zip file
[12:36:08] <IchGuckLive> you need to restart the pncconf
[12:36:09] <PetefromTn> There is a 5i25 firmware update on the forum you can download
[12:36:17] <CaptHindsight> yeah saw that
[12:36:49] <IchGuckLive> in 2.5.2 i got encoder error even with encoder=0
[12:36:52] <CaptHindsight> have to check my versions
[12:36:58] <IchGuckLive> in 2.5.3 never got this
[12:38:07] <CaptHindsight> pncconf lets me choose the 5125 but I get a HAL error when I launch
[12:38:14] <CaptHindsight> the setup
[12:38:51] <IchGuckLive> lanch of pncconf is ok
[12:39:06] <IchGuckLive> and you got both 7i76x1 7i76x2
[12:39:17] <IchGuckLive> unklick the 7i33
[12:39:26] <IchGuckLive> and accept is needet
[12:39:29] <CaptHindsight> hm2_5i25.0.stepgen.00.dirstep not found
[12:39:48] <IchGuckLive> is the 5i25 on power
[12:39:59] <CaptHindsight> yes
[12:40:02] <IchGuckLive> and the 7i76 also 12V+ 24V better
[12:40:17] <IchGuckLive> you got all 2 led lit on the 7i76
[12:40:43] <CaptHindsight> no just the yellow
[12:41:00] <IchGuckLive> then the 5i25 jumper is wriongf
[12:41:04] <IchGuckLive> wrong
[12:41:46] <CaptHindsight> but why the HAL error?
[12:41:57] <pcw_home> hm2_5i25.0.stepgen.00.dirstep is not a valid pin or parameter name
[12:42:05] <IchGuckLive> cause no power on the port
[12:42:09] <CaptHindsight> and /lib/firmware/5i25 is not there
[12:42:37] <CaptHindsight> oh so it's hardware vs missing driver issue
[12:42:48] <IchGuckLive> i suggest you did not the 5i25 update zip witch puts all the files
[12:42:58] <CaptHindsight> ?
[12:43:05] <pcw_home> probably a pncconf issue or missing xml file
[12:43:37] <CaptHindsight> I was trying to follow that howto but I'm not sure what it skips
[12:43:50] <CaptHindsight> have to rewrite it
[12:44:23] <CaptHindsight> the latest version of the .zip has a shell script but I have to check and see what it does and does not do
[12:44:49] <pcw_home> if you dont have /lib/firmware/5i25/some_xml_files, pncconf is not going to work right
[12:45:50] <CaptHindsight> cmorely said it does it all automagically now but maybe he just meant part of it
[12:46:14] <CaptHindsight> what I thought
[12:46:32] <CaptHindsight> 35 forum pages over 3 years on this
[12:47:31] <CaptHindsight> i thought maybe there was a change in file/directory structure
[12:47:56] <IchGuckLive> cap
[12:47:59] <IchGuckLive> http://linuxcnc.org/index.php/english/forum/39-pncconf/21670-5i25-firmware-xml-files-for-pncconf
[12:48:07] <IchGuckLive> here is the update file
[12:48:21] <pcw_home> I dont think so. I think pncconf always looks for its xml files on /lib/firmware/hm2/cardname/
[12:48:40] <IchGuckLive> i installd them from desktop and set W2 UP and there you go all is working
[12:48:42] <pcw_home> s/on/in/
[12:49:30] <IchGuckLive> CaptHindsight: the last one from cmorley i use
[12:50:22] <CaptHindsight> IchGuckLive: yeah, I think I grabbed that one as well
[12:50:57] <IchGuckLive> cp -r "$DIR/hostmot2-firmware-5i25" /usr/share/doc
[12:51:03] <IchGuckLive> cp -r "$DIR/5i25" /lib/firmware/hm2
[12:51:09] <IchGuckLive> so pcw is wright
[12:51:24] <CaptHindsight> yeah, so his installer skips that
[12:51:35] <IchGuckLive> it ends up on /lib/firmware/hm2/5i25
[12:52:40] <IchGuckLive> look if it is there band put W2 up
[12:52:48] <IchGuckLive> on the 5i25
[12:56:13] <CaptHindsight> IchGuckLive: jumper are all correct it's just a poorly written howto
[12:56:42] <CaptHindsight> and the installer only does some magic and not all
[12:58:42] <CaptHindsight> that crash borks the system, you can't shutdown properly
[12:58:57] <IchGuckLive> are the files there in terminal ls /lib/firmware/hm2
[13:07:28] <CaptHindsight> those are there
[13:07:54] <IchGuckLive> 5i25 and inside the xml files 7i76x2
[13:08:12] <CaptHindsight> yeah
[13:08:41] <IchGuckLive> then if the 7i76 dont see 2 led its the jumper andOr the power
[13:11:50] <CaptHindsight> 7i76 power?
[13:14:54] <IchGuckLive> yes but you said you added already 12V or more to the 7i76
[13:15:36] <CaptHindsight> started over
[13:15:45] <pcw_home> The 7I76 needs 2 power sources, on for the STEP/DIR and interface logic
[13:15:46] <pcw_home> (This normally comes from the FPGA card)
[13:15:48] <pcw_home> and the field I/O power (this a 8--32V power source on TB1
[13:15:56] <CaptHindsight> w1 and w2 are both in the LEFT position with no external power
[13:16:36] <CaptHindsight> first time using the 7i76
[13:16:40] <pcw_home> 5I25/6I25 needs W3 "UP" if you have cable power
[13:16:43] <IchGuckLive> is the 5i25 W2 up
[13:17:39] <pcw_home> Right its W2 not W3 on the 5I25
[13:17:41] <CaptHindsight> all up except w7
[13:18:02] <IchGuckLive> on 7i76 TB1 pin1 needs 12V or more TB1 pin 8 ground
[13:18:15] <CaptHindsight> so missing field power for IO needs to be connected or you get the HAL error?
[13:18:23] <IchGuckLive> yes
[13:18:32] <IchGuckLive> no field power will be a error
[13:18:37] <CaptHindsight> short answer
[13:19:00] <IchGuckLive> and the fieldpower needs to be there when the INI SETUP is loaded
[13:19:34] <IchGuckLive> Mashine on Linuxcnc on is the case as mesa
[13:21:20] <pcw_home> To be more specific, field power needs to be there if any 7i76 field I/O pins are accessed in the HAL file
[13:22:00] <CaptHindsight> ah ok
[13:22:10] <pcw_home> (pncconf must have some there)
[13:27:28] <CaptHindsight> light are all on now but same HAL error
[13:33:28] <pcw_home> what is the error again?
[13:35:40] <CaptHindsight> PCW: 5i25.0.stepgen.00.dirstep not found
[13:36:45] <CaptHindsight> checking his shell script, the firmware file is not there
[13:37:24] <CaptHindsight> we are just to check the whole thing over, he has 100 lines in the script that are not needed anyway
[13:37:40] <pcw_home> well again hm2_5i25.0.stepgen.00.dirstep is a bogus pin name
[13:38:32] <pcw_home> so either a pncconf bug or something missing so pncconf trips over it shoelaces
[13:38:42] <IchGuckLive> CaptHindsight: i can give you a ready made config for testing
[13:39:01] <IchGuckLive> CaptHindsight: hit mi Nick and give me a private mail
[13:41:30] <IchGuckLive> PCW i think he tapped int the trap with TB2 and Tb3
[13:41:49] <IchGuckLive> cable is TB3
[13:42:04] <IchGuckLive> on the 5i25

[13:44:47] <CaptHindsight> flood
[13:45:11] <CaptHindsight> yeah, were' going to start this install over
[13:45:14] <IchGuckLive> woudent you try from a ready made config
[13:45:37] <IchGuckLive> i can upload it also
[13:46:15] <CaptHindsight> pastebin but it looks like the config files were not all copied over by his script
[13:46:38] <IchGuckLive> the config is not pastebi nits a zip
[13:46:48] <IchGuckLive> including all files
[13:48:35] <IchGuckLive> CaptHindsight: foengarage.de/plasma5i257i76.zip
[13:49:32] <IchGuckLive> put the hole folder to cour config and start the ini not the gant!!
[13:49:37] <IchGuckLive> BY im off
[13:49:42] <CaptHindsight> hasta
[14:19:53] <CaptHindsight> hmm all the IO's come up as not found
[14:28:41] <pcw_home> all I/Os or all field I/Os? (field I/Os will have 7i76 in their name)
[14:34:20] <CaptHindsight> I thought this system had a complete Linuxcnc install, it's not all there yet
[14:39:16] <pcw_home> Oh
[14:52:32] <zeeshan> son of a
[14:52:42] <zeeshan> bought 6-32x3/4 bolts instead of 1"
[14:52:42] <zeeshan> ;[
[15:05:35] <CaptHindsight> where should .bit, .pin and .xml files be in /lib/firmware v2.5.3? hostmot2 or hm2?
[15:09:55] <Tom_itx> hm2 iirc
[15:10:54] <CaptHindsight> ok, we put them in both just to be safe
[15:13:40] <Tom_itx> quite sure it's hm2
[15:14:07] <Tom_itx> my tutorial would tell that i think
[15:15:26] <Tom_itx> /lib/firmware/hm2/7i43-4/
[15:15:27] <Tom_itx> yup
[15:18:44] <CaptHindsight> Tom_itx: tutorial?
[15:18:54] <PetefromTn> It's always something... I got the boss I need to machined designed and ready to go with the G-code file and went out to the shop to install my 3 jaw chuck on the mill table so I can hold the round part vertically without too much fuss and I found out that I am missing several of my damn T-slot nuts from my kit.
[15:19:33] <Tom_itx> CaptHindsight, yes for making bit files
[15:19:44] <CaptHindsight> have a link?
[15:19:45] <PetefromTn> Don't want to machine new ones but I guess I am gonna have to now if I want to get this done.
[15:20:01] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx14_install_index.php
[15:20:17] <CaptHindsight> oh yeah, I saw that before
[15:20:20] <CaptHindsight> nice
[15:20:38] <Tom_itx> there's another one for the older boards using xilinx 9.xx
[15:21:44] <PetefromTn> Swapped out the thick gooey nasty cutting oil that was in my bandsaw when I bought it and found that there is lots of nice nasty gooey metal scraps in the bottom of the trough. So I cleaned it all up and filled it with the new Coolant I am using on the mill. Works MUCH better now so I am cutting some steel bar to fab up a bunch of Tee slot nuts I guess now...
[16:09:52] <CaptHindsight> have it working now, firmware was in wrong location
[16:10:44] <CaptHindsight> so I guess when you get all those HAL errors for missing signals it's most likely check firmware first then debug power connections
[16:12:22] <PCW> actually the firmware is not used, only the xml files
[16:27:14] <Deejay> gn8
[17:32:22] <PetefromTn> Well made a couple Nice tee slot nuts from some scrap steel...back on track now. LOL
[18:01:24] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/BDC67763-DFF4-4C0F-9669-004892F50073_zpscplfvyxc.jpg
[18:01:26] <zeeshan> its all mounted :D
[18:01:37] <zeeshan> now the ugly part.. wiring. :{
[18:05:26] <Stratrascal> I need some help setting a VFD
[18:05:34] <Stratrascal> The menu is confusing me
[18:05:39] <jdh> one of those looks pretty crooked
[18:05:54] <zeeshan> jdh prolly shadow
[18:05:56] <zeeshan> of light hitting
[18:06:06] <jdh> good answer!
[18:06:22] <zeeshan> holes were preciselyh drilled! ;p
[18:06:36] <Stratrascal> THe manual for my VFD is here
http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/05/VFD03.pdf
[18:06:48] <jdh> stratrascal: I'd suggest asking the question
[18:06:51] <Stratrascal> I am trying to find out how to reverst
[18:06:58] <Stratrascal> reverse
[18:07:01] <jdh> oh, you did. nevermind:
[18:07:06] <Stratrascal> :)
[18:08:02] <jdh> always run in reverse? reverse on digital input? reverse on modbus command?
[18:08:07] <Stratrascal> What I dont understand is that if I set say, f1.2 I select it and press set and It tells me that parameters for that setting
[18:08:23] <Stratrascal> reverse from the panel
[18:08:46] <Stratrascal> I know I can change the order of the wires but I need to understand how to do it
[18:09:20] <Stratrascal> but some of the settingse are like f1.9 and there are several different thigs there
[18:09:31] <Stratrascal> Are you following?
[18:10:14] <Stratrascal> if someone would look at page 26 you will see what I am talking about
[18:12:05] <jdh> can you set it to reverse by itself, or just configure pins for forward/reverse?
[18:12:51] <Stratrascal> I should be able to change a setting to reverse it right? I am operating from the panel for now
[18:13:16] <Stratrascal> I have to figure out the menu before I try to use Mach3 to controll it
[18:13:32] <jdh> have you tried the mach3 channel?
[18:13:56] <Stratrascal> Ok, here we go, Please explain channel to me,
[18:14:08] <Stratrascal> :) I know i sound dense
[18:14:21] <jdh> sorry, that was a joke.
[18:14:37] <jdh> this is the LinuxCNC channel.
[18:14:42] <zeeshan> jdh i have a joke for you
[18:14:44] <jdh> hence the humor in my statement.
[18:14:46] <Stratrascal> Oh Duh,,,,,,,
[18:15:03] <Stratrascal> That just shows you how little I know about VFDs
[18:15:14] <PetefromTn> Mach3 is da debil...
[18:15:14] <zeeshan> what did the fast tomato say to the slow tomato??
[18:15:23] <zeeshan> Hey ketchup!
[18:15:25] <Stratrascal> You could have had me going for hours
[18:15:35] <Stratrascal> Pulp Ficton
[18:16:05] <zeeshan> jdh recommend me something
[18:16:20] <Stratrascal> I am getting ready to just revese 2 of the wires
[18:16:23] <zeeshan> the drivers put out 7A at 72Vdc
[18:16:28] <zeeshan> 18 gauge wire good enough? ;p
[18:16:36] <Stratrascal> but I have another probem with it too
[18:16:54] <jdh> anyway. in the time honored IRC tradition, I will not tell you the answer (because I have no idea) but will suggest setting up forward/reverse 2-wire mode as described and just jumper it for reverse if needed.
[18:17:19] <jdh> zeeshan: generally, drivers consume power.
[18:17:29] <Stratrascal> The RPM is showing 1/2 of the actual speed. It says 12000 but it is actually turning 24000
[18:17:59] <zeeshan> so fix the scaling factor
[18:18:02] <zeeshan> for your rpm display on the vfd
[18:18:22] <Stratrascal> Ok, I did not see that in the manual
[18:18:54] <jdh> I didn't see it either
[18:18:54] <Stratrascal> I think part of my problem is that I dont know what the teminology is
[18:19:11] <Stratrascal> Friggin Chinese manuals suck
[18:19:15] <jdh> but, that manual is written in some other language
[18:19:34] <Stratrascal> The one I linked?
[18:19:38] <jdh> yes
[18:20:16] <Stratrascal> You mean originally right? because the one I see is english
[18:20:24] <jdh> the words are english
[18:21:07] <zeeshan> page 21 shows you the reverse/fwd wiring
[18:21:12] <zeeshan> default two-line mode 1 ..
[18:21:21] <zeeshan> short fwd + com to get forward
[18:21:32] <jdh> looks like f3.7 might set the scaling if you were displaying linear speed.
[18:21:38] <zeeshan> and if you want reverse, unshort fwd+com, and short X?+com
[18:21:42] <jdh> to get forward? or to avoid reverse?
[18:22:07] <Stratrascal> I know I can change the dir with the wiring, but what If I need to change the dir after that?
[18:22:26] <jdh> it's just a jumper wire.
[18:22:50] <jdh> does your non-LinuxCNC control software have a modbus interface?
[18:22:56] <Stratrascal> Yeah, but eventually I want to control it with mach3
[18:23:15] <Stratrascal> You mean my breakout board?
[18:23:38] <zeeshan> oh
[18:23:39] <jdh> no, via rs485
[18:23:44] <zeeshan> thats easy?
[18:23:52] <zeeshan> you use a vfd control board like c41 or c6
[18:24:03] <jdh> sell him your c6
[18:24:11] <zeeshan> yes its for sale
[18:24:23] <Stratrascal> Oh yeah. Whacha want for it?
[18:24:37] <jdh> if you use one of those boards, it will handle the forward/reverse anyway
[18:25:01] <Stratrascal> Ok that is actually where I want to go
[18:25:27] <Stratrascal> I was just taking it one step at a time. Like learning how to use the panel on the VFD to control it.
[18:26:00] <jdh> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus
[18:26:14] <PetefromTn> I ran modbus on my 3hp VFD on my RF45 with Mach3 on my old machine.
[18:28:41] <zeeshan> hey
[18:28:43] <zeeshan> they have my drive on there
[18:28:44] <zeeshan> lol
[18:29:09] <zeeshan> so youre telling me
[18:29:14] <zeeshan> i dont even need a goddamn silly ass c6 board?
[18:29:16] <zeeshan> with modbus?
[18:29:34] <zeeshan> i just need a rs232-rs485 adapter?
[18:29:52] <Stratrascal> you talking to me?
[18:29:56] <zeeshan> no jdh
[18:30:05] <Stratrascal> oh ok :)
[18:30:29] <Stratrascal> I am learning a lot here, Thats what it's for right?
[18:30:41] <zeeshan> yea according othat linux cnc site
[18:30:46] <zeeshan> you don't need no immediate board in between
[18:30:50] <zeeshan> fak jdh, why didnt you tell me before
[18:30:51] <zeeshan> ;[
[18:33:48] <zeeshan> okay im chucking the c6 card
[18:33:54] <zeeshan> this modbus method looks way better.
[18:36:27] <Stratrascal> So If I have this right, My panel actually detaches and there is a Modbus connection that is actually how the panel connects. I can use the modbus interface instead of the panel? does that sound right?
[18:36:35] <zeeshan> yea
[18:37:16] <Stratrascal> I thought I was going to have to wire all the different parameters to my breakout board.
[18:37:30] <zeeshan> no modbus avoids that
[18:37:40] <zeeshan> you literally need a rj45/rj11 cable coming out of your vfd
[18:37:43] <zeeshan> and going into the serial port
[18:37:47] <zeeshan> but you need to be running linux cnc
[18:37:53] <Stratrascal> Great, I can handle that.
[18:38:05] <zeeshan> i dont think mach can handle it.
[18:38:14] <zeeshan> with mach you'll need a c6/c41 card
[18:38:51] <PetefromTn> Yeah if you can program it Modbus is the way to go.
[18:39:04] <zeeshan> dude
[18:39:06] <zeeshan> i wish i knew about this..
[18:39:09] <Stratrascal> Im watching a video on it now
[18:39:10] <PetefromTn> Works with Mach3 as well as LinuxCNC which is WAY better...
[18:39:10] <zeeshan> its wayyyy simpler to wire it in
[18:39:32] <zeeshan> my vfd has a rj11 connector on it
[18:39:56] <PetefromTn> I may still have the file a friend made for me to run Modbus on the mach3 machine I used to have before I sold it and stepped UP to LinuxCNC>>.
[18:40:21] <zeeshan> with modbus
[18:40:27] <zeeshan> i can program the drive right from the computert
[18:40:29] <zeeshan> this is sick
[18:40:32] <Stratrascal> That is how my panel is connected. if I remove the panel it exposes the rj45
[18:40:35] <zeeshan> change the motor rated current on the fly!
[18:40:35] <zeeshan> ;p
[18:40:59] <PetefromTn> Yeah and if you are clever with it you can do a lot more than that like read load etc..
[18:41:16] <zeeshan> Stratrascal: buy my c6 card
[18:41:17] <zeeshan> ;D
[18:41:33] <Stratrascal> :)
[18:41:40] <PetefromTn> Slap it on Ebay and the CNCzone someone will buy it.
[18:42:21] <Stratrascal> Oh you can control the cooling pump. Kewl
[18:42:54] <zeeshan> i wasted so much time figuring out the c6 wiring
[18:42:55] <zeeshan> =/
[18:43:03] <PetefromTn> Man I machined that steel earlier with a new carbide rougher in the VMC to make those Tee slot nuts... Cut like butter. Amazing how powerful and rigid this machine is compared to my RF45...
[18:43:03] <zeeshan> jdh: thank you so much for mentioning modbus.
[18:43:16] <zeeshan> i've heard people talk about it, but never knew how it was implemented
[18:43:31] <zeeshan> PetefromTn: your machine also weighs lik what
[18:43:32] <zeeshan> 12000lb
[18:43:36] <zeeshan> ofcourse its more rigid :P
[18:43:41] <PetefromTn> Nope 7k...
[18:43:50] <zeeshan> still about 7x more weight
[18:44:04] <PetefromTn> Yeah but you gotta see it to really appreciate it. yup..
[18:44:06] <zeeshan> needs lots of cast iron to dampen the vibrations
[18:44:19] <PetefromTn> What vibrations LOL..
[18:44:24] <zeeshan> oh trust me
[18:44:25] <zeeshan> they are there
[18:44:29] <zeeshan> but they're being damped
[18:44:56] <PetefromTn> Funny thing is I probably had more money in my RF45 retrofit than I do in this whole machine.
[18:45:23] <zeeshan> i might sell my manual mill
[18:45:25] <zeeshan> and grab a vmc
[18:45:30] <zeeshan> if i can find one for 3k locally
[18:45:46] <zeeshan> whats the footprint of your vmc?
[18:45:47] <PetefromTn> Wondering about hooking my VMC's VFD up via modbus. Might make things better and possibly fix my slight noise issue with the 7i77 card.
[18:46:07] <zeeshan> hey is rj12 cable shielded?
[18:46:25] <PetefromTn> Honestly it is not much larger than the enlcosure I had on my RF45.. It is about a nine foot square footprint.
[18:46:55] <zeeshan> thats huge
[18:47:06] <PetefromTn> I am probably going to sell my manual Lathe once I get this thing finished.
[18:47:12] <PetefromTn> No actually it is not really.
[18:47:25] <zeeshan> the rf45 is tiny.
[18:47:25] <Stratrascal> Does the breaking resistor just allow you to slow the spindle down fast?
[18:47:30] <PetefromTn> basically take two sheets of plywood and pop them on the floor.
[18:47:35] <zeeshan> Stratrascal: yea its not needed in most applications
[18:47:38] <PetefromTn> Stratrascal: yeah..
[18:47:38] <zeeshan> unless you want instant stop.
[18:47:56] <PetefromTn> It is a damn good idea to have one tho... even if you don't really need it.
[18:48:19] <Stratrascal> Ok Ill get one.
[18:48:21] <PetefromTn> Makes spool up and down times much faster..
[18:48:33] <Stratrascal> I wonder why they just dont implement it internally
[18:48:42] <PetefromTn> They usually do..
[18:48:46] <Stratrascal> I mean it is just a resistor
[18:48:47] <PetefromTn> but maybe not too large.
[18:48:53] <zeeshan> ok back to wiring
[18:48:53] <zeeshan> brb
[18:49:24] <PetefromTn> Anyone here running a VFD on Modbus with LinuxCNC? how do you like it and how difficult was it to program?
[18:51:26] <zeeshan> PetefromTn:
[18:51:29] <zeeshan> if you look at that page
[18:51:37] <zeeshan> it shows a bunch of vfds with the code already there for em
[18:51:43] <zeeshan> luckily mine is on there which is a mvx9000 by eaton
[18:51:54] <zeeshan> i have like 6 of those drives that my boss gave me
[18:52:01] <PetefromTn> what page?
[18:52:01] <zeeshan> cause they were being obseleted
[18:52:10] <zeeshan> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus
[18:52:24] <zeeshan> the second link for each vfd is the code
[18:52:27] <Stratrascal> Oh, I get it now. the dir is not controlled from the software, it is on the terminal block. Duh... I was looking in the wrong place all along. I feel stupid, but I feel better now
[18:52:50] <zeeshan> jdh wake up
[18:52:50] <PetefromTn> OOh they don't have my Hitachi WJ200 but they have the SJ200 in there wonder if it is similar enough to use it.
[18:52:51] <zeeshan> ;D
[18:53:26] <zeeshan> okay back to wiring
[18:53:29] <zeeshan> minus the stupid c6 card.
[18:53:41] <zeeshan> i want to slap myself cause jdh was right
[18:53:46] <Stratrascal> Have you guys heard of a Quietdrill 1010?
[18:53:52] <zeeshan> he told me i shouldnt worry about the c6 cause i'll be chucking it out
[18:53:52] <zeeshan> LOL
[19:19:34] <Connor_iPad> Yo
[19:22:52] <Connor_iPad> PetefromTn: Ping.
[19:22:55] <PetefromTn> yoyo..
[19:23:07] <PetefromTn> PM
[20:07:10] <Connor_iPad> Anyone using modbus for VFD ?
[20:08:41] <zeeshan> question for you guys
[20:09:06] <zeeshan> i have my 12v and 5v +/- wires running next to the 110V hot,neutral,gnd lines
[20:09:13] <zeeshan> should i shield the 12v and 5v power lines?
[20:10:14] <Tom_itx> shouldn't need to
[20:10:30] <zeeshan> phew
[20:10:47] <zeeshan> something seems wrong here
[20:10:57] <zeeshan> the 72V + and - going to my stepper drivers
[20:10:59] <zeeshan> is only 18 gauge?
[20:11:11] <zeeshan> the stepper drivers draw 7A max
[20:11:13] <Tom_itx> i used 18 iirc
[20:11:21] <zeeshan> what size motors?
[20:11:28] <Tom_itx> nema23
[20:11:34] <zeeshan> these are nema 34 1200z
[20:11:36] <zeeshan> oz
[20:11:36] <Tom_itx> but i'm not drawing 7A either
[20:11:40] <zeeshan> fak
[20:11:48] <zeeshan> i think to be safe, i should run 14 gauge
[20:12:07] <Tom_itx> i'm not exactly sure but 18 may be pushing it
[20:12:09] <zeeshan> im running 12 gauge on the input side of the power supplies
[20:12:16] <Connor_iPad> Depends on length.
[20:12:25] <zeeshan> theyre like 1 foot lengths
[20:12:39] <Connor_iPad> For the 18 gauge ?
[20:12:57] <zeeshan> yes
[20:13:08] <zeeshan> just to clarify
[20:13:39] <zeeshan> from the output side of the 72V dc supply, im running 18 gauge wire to the gnd and positive terminals on the stepper drivers
[20:14:00] <PetefromTn> Has anyone ever done a modbus VFD control via linuxCNC here that works well? I am curious as to how it works and also if things like load meters could be added to LinuxCNC via modbus.
[20:14:30] <Connor_iPad> At 1 foot length. 18 gauge probably fine.
[20:14:35] <Connor_iPad> Stranded or solid?
[20:14:45] <zeeshan> stranded
[20:15:11] <Connor_iPad> They're online calculators you can find for calculating gauge needed they key is amps and length.
[20:15:39] <zeeshan> could you link me one?
[20:15:42] <zeeshan> i've always gone by charts
[20:16:04] <Tom_itx> 16 would be better
[20:16:20] <Connor_iPad> I Run 18 gauge alarm wire for my steppers. 48v @ 5amps. 10 to 15 feet.
[20:16:29] <Tom_itx> so do i
[20:16:39] <zeeshan> yea but these suckers draw 7amps at 72V
[20:16:57] <Tom_itx> if anything there will be loss
[20:17:14] <Tom_itx> and on the other end it will get hot
[20:17:32] <Connor_iPad> Are you asking for the wire going from the stepper driver to the motor? What's that distance?
[20:17:57] <Connor_iPad> Or supply wires to the driver from PSU ?
[20:21:36] <zeeshan> supply wires to driver from PSU
[20:21:57] <zeeshan> the stepper driver to motor wires i haven't done yet
[20:21:59] <zeeshan> that'll be very last
[20:23:19] <Connor_iPad> 16 gauge would be fine. But 18 would work for that short of a run.
[20:24:40] <zeeshan> one more question
[20:24:49] <zeeshan> the signal wires coming from my bob to the stepper drivers
[20:24:51] <Connor_iPad> How Many oz/in torque on motors?
[20:24:57] <zeeshan> its a set of shielded wires..
[20:25:12] <zeeshan> where do i ground the ground of the shielding
[20:25:20] <zeeshan> and from what i've read, i only do it on one side?
[20:25:26] <zeeshan> the motors are 1200oz-in
[20:25:30] <Tom_itx> only gnd one side yes
[20:25:35] <Connor_iPad> Bob side
[20:25:41] <Tom_itx> gnd in a STAR configuration on the controller side
[20:25:42] <zeeshan> so i just ground it where? on the chassis?
[20:26:33] <Tom_itx> that would probably work fine
[20:26:39] <zeeshan> see i always get confused on this
[20:26:43] <zeeshan> theres ground on the actual breakout board
[20:27:06] <zeeshan> do i ground there or the chassis
[20:27:10] <Connor_iPad> What sort of machine these steppers for?
[20:27:13] <zeeshan> cause right now, my chassis has all my grounds for my hot wires
[20:27:17] <zeeshan> lathe
[20:28:45] <Connor_iPad> What size?
[20:28:49] <zeeshan> 12x36
[20:29:17] <Connor_iPad> That's a nice size. Though those sound a bit over powered.
[20:29:21] <Tom_itx> don't use the frame to route a power return path (if i read that right)
[20:29:23] <zeeshan> better to overpower
[20:29:25] <zeeshan> then underpower
[20:29:37] <zeeshan> Tom_itx: no the neutral wires don't connect to the chassis
[20:29:43] <zeeshan> you know the green wires coming from the power outlet?
[20:29:45] <zeeshan> aka bare ground
[20:29:49] <zeeshan> they're grounded on my chassis right now
[20:29:54] <Tom_itx> earth gnd
[20:29:57] <zeeshan> yes
[20:30:04] <zeeshan> earth gnd from each power supply goes to the chassis
[20:30:11] <Connor_iPad> Depends. Larger ones don't have higher rpm as lower torque.
[20:30:13] <zeeshan> and the wire coming from the breaker box is grounded too
[20:30:25] <zeeshan> Connor: i wanted low end torque
[20:30:32] <zeeshan> to ensure i can do heavy threading ;p
[20:31:34] <zeeshan> okay one last time
[20:31:45] <zeeshan> the shielding ground wire goes on the chassis
[20:31:50] <zeeshan> and not the ground terminal on the BOB
[20:31:52] <zeeshan> right?! :D
[20:43:48] <PetefromTn> How can I make the G-edit file I am using to edit my tool table stay on the desktop?
[20:51:46] <Stratrascal> Hey Thanks zeehan and PetefromTN!
[20:53:24] <PetefromTn> Stratrascal: Thanks to you for giving me an idea man. Good luck with your setup.
[20:54:39] <Stratrascal> Hey would you guys help me figure out a speed and feed?
[20:55:32] <Stratrascal> here is the bit and I am milling aluminum
http://www.ebay.com/itm/380784225041?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[20:56:33] <Tom_itx> http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[20:56:57] <Stratrascal> thanks
[20:57:12] <Tom_itx> use a good chip load on aluminum
[20:57:20] <Tom_itx> unless your machine won't take it
[20:57:30] <PetefromTn> Yup that is what I am using for F and S..
[20:57:31] <Tom_itx> but remember it's a small bit
[20:57:32] <Stratrascal> by good you mean a lot
[20:58:13] <Stratrascal> ?
[20:58:18] <PetefromTn> Maybe .00015 chipload?
[20:58:36] <Tom_itx> depends on the machine
[20:58:43] <Tom_itx> it should do .001 i'd hope
[20:59:14] <Stratrascal> well I have a 3hp 24000 2.2K spindle.
[20:59:21] <PetefromTn> Oops too many zeros...
[20:59:33] <Stratrascal> Should that do?
[20:59:40] <Tom_itx> generally between .002 - .004 chip load
[20:59:46] <Tom_itx> for aluminum
[21:00:01] <Tom_itx> depending on the tool diameter, depth of cut etc etc
[21:00:23] <Stratrascal> I want a nice cut the speed doesnt matter that much
[21:01:11] <Stratrascal> what is "OAL"?
[21:01:20] <PetefromTn> 1/8 inch endmill is pretty small so go to the low side. Tool manuf should be able to give you proper F and S..
[21:01:22] <Tom_itx> overall length probably
[21:01:42] <PetefromTn> OAL is the amount the tool sticks from the collet as I read it.
[21:03:53] <Stratrascal> The only info I can see on the tool is Dia .1250 size 1/8 2 flutes length of cut .500 OAL 1.5 center-cut
[21:04:36] <Tom_itx> that's a rather long cut for an 1/8
[21:04:38] <Tom_itx> " em
[21:05:05] <Tom_itx> may chatter more than one with .25" LOC
[21:05:12] <jdh> I got some 1" cut 1/8ths
[21:05:45] <Tom_itx> i didn't say they didn't make em but i wouldn't use it for hogging out something
[21:06:00] <Stratrascal> Well, I'm not going to put it all the way in, (anyway thats what I told her) :)
[21:06:15] <Tom_itx> tease
[21:06:28] <jdh> I used them for cutting 1" acrylic
[21:06:36] <Stratrascal> .25 is the depth of cut?
[21:06:39] <Tom_itx> then you had a need for it
[21:06:46] <Tom_itx> flute length
[21:07:09] <Stratrascal> this tool you sent me to is asking more than I know
[21:07:20] <Tom_itx> generally use the shortest flute length required for the job
[21:07:32] <Tom_itx> google it then
[21:07:40] <Tom_itx> you need to learn all about it
[21:08:54] <Stratrascal> I have been trying. but I don't trust myself. I have to get some confidence because I have busted up about 150 dollards worth of bits because I was too cheap to buy a good spindle, Now I have a decent one.
[21:09:42] <Stratrascal> and from my little manual test It was worth it in noise saving alone.
[21:10:05] <Tom_itx> on those small bits i think i'd shoot for a .001" chip load
[21:10:22] <Tom_itx> you can go from there if it works good
[21:10:33] <Stratrascal> Ok,
[21:10:35] <Tom_itx> maybe bump it up or down to get a good result
[21:10:48] <jdh> and then I'd install LinuxCNC and get rid of that silly mach stuff.
[21:11:24] <Tom_itx> then you can put it in all the way
[21:11:34] * jdh nods
[21:12:29] <Stratrascal> Well, I will definatley check it out. I started in this adventure and I don't know anyone to help me out
[21:12:46] <Stratrascal> Do they have a demo?
[21:12:48] <Tom_itx> now you do
[21:12:53] <jdh> demo?
[21:13:11] <Stratrascal> Well one I don't have to pay for this min
[21:13:18] <jdh> you never have to pay for it
[21:13:28] <jdh> all free, source code included.
[21:13:43] <Stratrascal> Really?, I wish I had come here a lot sooner. I would have saved thousands
[21:13:59] <zeeshan> i did the calcualtions
[21:13:59] <Tom_itx> yup
[21:14:06] <zeeshan> 18 gauge wire is good enough for 1 foot run
[21:14:14] <Stratrascal> I assumed that LinuxCNC was meant to be run on a Linux box
[21:14:16] <zeeshan> its only first of all .1% voltage drop
[21:14:26] <zeeshan> and 80C wire melts at 15A
[21:14:27] <jdh> it is, hence the Linux
[21:14:33] <zeeshan> derate it, and its good to 8a
[21:14:40] <Stratrascal> I have never used Linux
[21:14:41] <zeeshan> i dunno how that stupid chart says 2.3A
[21:15:51] <jdh> you have 1 PS per drive?
[21:16:45] <zeeshan> yes
[21:16:52] <zeeshan> cause they're switched
[21:16:57] <zeeshan> and rated to 8.8A
[21:16:59] <zeeshan> or something like that
[21:17:20] <jdh> have you measured actual current?
[21:17:27] <zeeshan> no
[21:17:30] <zeeshan> im going by data sheets
[21:17:41] <zeeshan> the stepper driver at maximum can draw 7amps
[21:17:46] <zeeshan> its the kl-8070d
[21:18:04] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/7B7B29EA-E371-4BBF-A98D-E53B9F52D6AB_zpszhwclimz.jpg
[21:18:09] <zeeshan> this is what the box looks like right now
[21:19:19] <Tom_itx> Stratrascal, for reference i'm using .0008 chip load on my lightweight sherline
[21:19:34] <Tom_itx> you should easily be able to cut .001
[21:20:13] <Tom_itx> and probably more
[21:21:50] <jdh> with little or no information,I bet you never use more than 4amps
[21:22:35] <Stratrascal> What is length of cut?
[21:22:48] <Tom_itx> how deep are you cutting?
[21:23:02] <Stratrascal> Me?
[21:23:07] <Tom_itx> flute length is how long the cutter part of the tool is
[21:23:10] <Tom_itx> you
[21:23:26] <Tom_itx> LOC is length of cut... how deep are you cutting
[21:23:51] <Tom_itx> or DOC depth of cut
[21:24:09] <Tom_itx> WOC width of cut... how much of the cutter are you using
[21:26:36] <Stratrascal> Sorry, I am cutting 7mm aluminum
[21:27:08] <Stratrascal> 6061 aluminum
[21:34:21] <Stratrascal> So does 1016mm/m at 20k sound right?
[21:38:22] <PetefromTn> Running parts!!
[21:39:09] <jdh> you have a 20krpm spindle?
[21:40:04] <Stratrascal> 24k
[21:41:04] <Stratrascal> I also have a 80,000 K but the collet is messed up right now
[21:41:19] <jdh> nifty. what kind of machine?
[21:41:36] <Stratrascal> A cheap chinese desktop
[21:42:26] <Stratrascal> kind of like this one
[21:42:27] <Stratrascal> http://www.ebay.com/itm/PROFESSIONAL-3-AXISES-6040-CNC-ROUTER-ENGRAVER-DRILLING-MILLING-MACHINE-p9-/170795467640?pt=LH_DefaultDomain_0&hash=item27c4340378
[21:42:54] <jdh> I've been thinking of getting one of those also
[21:43:12] <jdh> http://www.carving-cnc.com/accessories/6040mainbody.html
[21:43:28] <jdh> that and a G540 or something
[21:44:25] <Stratrascal> The biggest problem I had was that the Z axis spindle holder was just like the one shown in the one you linked to
[21:44:46] <Stratrascal> it was for a 50mm spindle and I wanted an 80
[21:45:09] <jdh> did you make a new one?
[21:45:21] <jdh> this one has a 65mm
[21:45:22] <Stratrascal> I could not find one to buy so I designed one and printed it out at work.
[21:46:10] <Stratrascal> There are no good options for a 50mm spindle, 65 you have a lot more options
[21:46:38] <jdh> have you cut 6061 with it?
[21:46:51] <Stratrascal> Just a little test.
[21:47:01] <Stratrascal> That is what I am trying to figure out right now.
[21:47:33] <Stratrascal> I have broken so many tools I want to get it right now.
[21:47:50] <Stratrascal> Should you have to run a spray to cut aluminum?
[21:48:01] <jdh> I have a smallish mill. I would like a larger router than my current one for mostly plastic/acrylic
[21:48:25] <jdh> I use a squirt bottle of liquid wd40 for big cuts on my mill.
[21:48:49] <Stratrascal> I have a little sprayer
[21:49:12] <jdh> wouldn't hurt. getting the chips out helps also
[21:49:16] <Stratrascal> it was cheap, 70 dollars i think
[21:49:32] <Stratrascal> I was going to just run some air.
[21:49:54] <jdh> their complete 6040 says 'new version S80'. I wonder if it has an 80mm spindle mount
[21:50:53] <Stratrascal> Actually that one you showed Is identical to mine, but mine came with really crappy electronics.
[21:51:07] <jdh> that's why I wanted the one with no electronics
[21:51:18] <Stratrascal> Good Idea
[21:51:50] <Stratrascal> I got some 540 in/lb steppers
[21:52:11] <Stratrascal> My Tim Allen gene is expressing itself. :)
[21:52:24] <jdh> I have 540's on my little mill
[21:52:35] <Stratrascal> Hold on I'll take a pic
[21:56:22] <jdh> there are 80mm (and 65mm) spindle mounts on ebay.

[21:57:16] <jdh> it's marked private
[21:57:29] <Stratrascal> Ok hold on
[21:59:30] <Stratrascal> What do you use to share photos on?

[22:00:16] <jdh> imagebin
[22:00:43] <Stratrascal> http://imgur.com/tuU3ul0
[22:01:05] <jdh> that's a lot of stepper
[22:01:12] <jdh> speedy?
[22:01:14] <Stratrascal> BuYaaa
[22:01:27] <Stratrascal> Lot of spindle too
[22:02:09] <jdh> http://www.ebay.com/itm/171202207408
[22:02:32] <Stratrascal> I have done a lot of failing but not for the lack of trying. Now I think I can cut some aluminum
[22:03:36] <RyanS> speaking of coolant, I don't see the point of fogbusters. do they even clear the chips?
[22:03:39] <jdh> you really have to do something about taht mach thing
[22:07:13] <Stratrascal> Well, I have never used Linux. I used to be a Master of DOS, Is it similar to dos?
[22:07:28] <jdh> you can type things.
[22:07:43] <Stratrascal> Yep
[22:08:05] <Stratrascal> I actually like it better than Windows. You feel more in control.
[22:08:15] <jdh> download the livecd, boot it. You can test most things from the CD
[22:08:30] <Stratrascal> send me a link.
[22:08:40] <jdh> google.com
[22:08:46] <Stratrascal> hehe
[22:09:16] <Stratrascal> what do you mean by boot it. is that like mounting a drive or do I have to restart and boot into it
[22:09:21] <RyanS> don't have to have www
[22:09:55] <jdh> you'll figure it out.
[22:10:23] <Stratrascal> the machine I am running my router on is an old pice of crap. Will it run the linux ok?
[22:10:45] <jdh> yep. Linux runs on about anything. Linuxcnc does not like laptops though
[22:11:07] <Stratrascal> It's an old Dell Desktop
[22:11:41] <Stratrascal> Ok, I have a lot of stuff on the table right now. But I will definately check it out.
[22:12:04] <jdh> what drivers are you using with the 540s?
[22:12:07] <Stratrascal> So, what is better about LinuxCNC?
[22:12:43] <Stratrascal> I have not used anything but Mach3 so I dont have anything to compare it to.
[22:12:43] <jdh> the smug sense of superiority over windows users
[22:12:56] <Stratrascal> Ok, I can live with that.
[22:13:05] <RyanS> Exactly so no reason at all :)
[22:13:16] <PetefromTn> In short....It works...all the time.
[22:13:50] <RyanS> Because Mach3 is sooooo expensive :P
[22:14:03] <jdh> there are many reasons. some of which are of no consequence for some uses.
[22:14:12] <PetefromTn> I got a Mach3 license here...Ya want it LOL..
[22:14:27] <Stratrascal> Here is one of my other toys
[22:14:30] <Stratrascal> http://imgur.com/oAueG6O
[22:15:10] <jdh> yeah, glue gun printers and mach... I don't think I'd mention those much here :)
[22:15:30] <RyanS> ummm because people like debugging an esoteric operating system rather than actually cut metal ?
[22:15:54] <Stratrascal> Here is the one I am building
[22:15:58] <jdh> I'd hardly call it esoteric. And I haven't debugged any OS stuff in 15 years
[22:16:23] <pcw_home> I didn't think Windows XP was esoteric
[22:16:42] <jdh> heh
[22:16:47] <Stratrascal> http://imgur.com/q19nibL
[22:16:56] <RyanS> I was talking about linux...
[22:17:11] <Stratrascal> And after I get all this stuff working I am building a Laser Cutter
[22:17:30] <RyanS> Really, I'm just here because I find CNC machines interesting
[22:17:42] <RyanS> I don't think I'd attempt to convert one myself
[22:17:50] <Stratrascal> Anything that moves by computer controll is kewl
[22:21:45] <RyanS> Makerbot .. hmmm would I get laughed at here if I said I was considering a Tormach 770?
[22:22:38] <jdh> I'd take one
[22:22:40] <PetefromTn> Man I am really starting to love this machine. Another perfect part finished. This time I did not have to change any settings in the G-code. NICE>>>
[22:23:44] <Stratrascal> Who cares if anyone laughs It's like fat girls and mopeds.
[22:23:55] <RyanS> I just want to make stuff, it seems like you have to really be enthusiastic about converting to be any point to it
[22:24:07] <jdh> fat girls are grateful. MOpeds just mean you got a dui
[22:24:26] <jdh> I only converted mine because I couldn't affort a pre-made one.
[22:24:32] <RyanS> fat girls & mopeds?
[22:24:34] <Stratrascal> they are fun to ride but you don't want anyone to see you on one
[22:25:57] <RyanS> But by the time you've bought components, realise your spindle doesn't have the rpm, purchasing more components. Do you really save much
[22:26:06] <Stratrascal> I know I am asking a lot of questions but what is "Lead Angle"?
[22:26:38] <PetefromTn> http://imagebin.org/293463
[22:26:51] <zeeshan> PetefromTn: looking nice mate
[22:26:51] <zeeshan> ;D
[22:26:56] <RyanS> Something to do the cutting tool geometry?
[22:27:18] <Stratrascal> PetefromTn -> Shweeeeet!!!!
[22:27:24] <PetefromTn> Yeah finish is much better this time I changed the code somewhat.
[22:27:40] <Stratrascal> What is it?
[22:27:43] <PetefromTn> Stratrascal: Thanks man. Been a long haul getting here but it is worth the trip!!
[22:28:13] <PetefromTn> I gotta make like then of these things...
[22:29:10] <RyanS> I made an appointment with a guy to look at tormach 1100 and the fucknuckle wasn't even home
[22:30:06] <Stratrascal> Someday, I will be able to make something like that. I must be getting old. Used to be all I wanted was to Play guitar, snort and get laid, Now I just want to cut up aluminum.
[22:31:39] <RyanS> PetefromTn what sort of machine was that made with mill, lathe?
[22:33:28] <PetefromTn> RyanS: It was machined on a 1997 Cincinatti Arrow 500 Vertical Machining center retrofitted with LinuxCNC and a LOT of help from the folks here LOL...
[22:33:45] <RyanS> cool
[22:34:22] <RyanS> Was any postprocessing done to the part like polishing?
[22:34:37] <PetefromTn> Really starting to get the hang of using this machine finally.
[22:34:48] <Stratrascal> What CAD do you use?
[22:34:51] <PetefromTn> No actually I just now pulled it off the machine just a second ago LOL.
[22:35:14] <PetefromTn> This was drawn in Freecad and Machined with CamBam....
[22:35:55] <Stratrascal> I have been using Bobcad. It was not very intuitive at first but I am getting the hang of it.
[22:36:26] <PetefromTn> Nothing wrong with Bobcad except the salesholes... I got a good friend who runs a machine shop near me and that is all he uses.
[22:37:24] <Stratrascal> That is funny what you said about the salesholes. Because I was just thinking about that. I told them I did not want support but they billed me for it anyway.
[22:37:47] <Stratrascal> I ripped them a new one in email.
[22:38:35] <Stratrascal> Hey Yall, I have got to get something to eat. But Thanks for all the help. I'll be around for sure.
[22:38:38] <RyanS> So the sides of it. The cylindrical part was that side milled and a long endmill? seems like you don't even need a lathe
[22:39:43] <PetefromTn> http://imagebin.org/293464 My setup...
[22:40:01] <PetefromTn> Yeah the whole part was machined in the VMC..
[22:41:01] <jdh> how do you center on the chuck/part?
[22:41:40] <RyanS> PetefromTn , so it was a used machine with a dead controller (presumably affordable) with a retrofitted controller?
[22:42:48] <PetefromTn> Well I took a two sided broken 5/8 endmill and put it in an ER32 Cat40 Collet Chuck and then took it down to the lathe chuck and clamped the lathe chuck jaws around the toolbit and then tightened down the clamps holding it to the mill table. Then I set my G56 offset X and Y to that point.
[22:42:56] <PetefromTn> BRB....
[22:43:22] <jdh> heh, much easier than finding the clamped down center
[22:44:20] <RyanS> I wouldn't like to see the results of crashing that machine :P
[22:53:09] <jdh> http://i142.photobucket.com/albums/r98/isiahstites/Machining/101_4318.jpg
[22:53:19] <jdh> I'd take one of those... and I don't even have a need for one.
[22:53:48] <jdh> I do have that same cheapass HF bandsaw in the corner.
[22:54:39] <PetefromTn> RyanS: Sorry man had to go take care of something. Yeah I bought the machine used from a fellow nearby who upgraded to larger newer machines. This one had a Bad Z axis drive among other things. Originally I tried to run it with the original control and spent a bunch of money getting the drive and other things fixed but wound up gutting the entire thing and starting over.
[22:54:53] <Stratrascal> What happens when your RPM is too fast? Gets hot?
[22:58:09] <RyanS> PetefromTn cool, sounds like a lot of work
[22:58:57] <PetefromTn> RyanS: Honestly this machine was less work than my RF45 where I had to build everything and machine ballscrews, mounts, etc. etc.
[22:59:32] <RyanS> jdh obviously he had a spare $70k
[22:59:57] <PetefromTn> All I had to do with this machine was sell off the old parts which sold for a good price and buy the correct sized new parts and design the same sort of system only more powerful that I used before with Commercial style drives.
[23:00:17] <PetefromTn> RyanS: $70k?
[23:01:07] <RyanS> nah the haas mini mill jdh linked
[23:05:35] <PetefromTn> I am thinking hard about switching my spindle control over to Serial Modbus.
[23:06:25] <PetefromTn> My HItachi WJ200 Drive has the capability and I just need to get an RS232-RS485 adapter and a shielded cable and I can hook it up.
[23:07:41] <PetefromTn> I was looking at that LinuxCNC Modbus link posted earlier and there is already some support information for the HItachi SJ200 drive so I am wondering how similar or different my WJ200 drive would be. Sure would be nice If I could just use the information for my drive.
[23:11:51] <PetefromTn> I thought the Haas Mini Mills were cheaper than that... You can probably buy a stipped down VF2 for $70k... or so..
[23:12:23] <RyanS> I was just thinking additional costs for tooling
[23:12:34] <RyanS> I think they are about 50k
[23:12:49] <PetefromTn> Besides if I was gonna get one of those I would just get a nice Drill and Tap center from Brother that would kick its ass...
[23:13:25] <PetefromTn> I almost bought an older brother machine to retrofit before I got this VMC. They are sweet machines and FAST as hell.
[23:13:45] <PetefromTn> Tooling is certainly expensive but it is nowhere near $20k..
[23:14:39] <PetefromTn> http://www.youtube.com/watch?v=-WvXc9gKkCM
[23:14:47] <PetefromTn> This is the kind of machine I almost bought.
[23:16:31] <PetefromTn> Not half bad for a 30 taper..
[23:18:44] <PetefromTn> http://www.youtube.com/watch?v=wfy3kdm0h9c
[23:19:13] <PetefromTn> THese are relatively small footprint machines too. Quite a bit smaller than even my Arrow 500. This one in the video is retrofit.
[23:21:00] <RyanS> heaven forbid the cost if they need some major parts for it
[23:22:36] <PetefromTn> Well if you retrofit like I did and remove almost the entire electronics package it is not too bad really. Besides you only need this machine if you want to make money with it so hopefully you get some work to pay for any repairs and make a nice profit.
[23:24:10] <PetefromTn> They have a very simple and robust toolchanger mechanism.
[23:27:59] <RyanS> What sort of parts, customers are you thinking of with your machine?
[23:31:35] <PetefromTn> LOL whatever I can find. Just got it running recently. I do make a lot of custom parts for Precision airgun guys.
[23:33:16] <RyanS> ok
[23:33:36] <PetefromTn> I have a customers part coming in probably tuesday that he wants me to machine a bunch of. Hopefully it will turn into a regular thing.
