[03:16:32] <Deejay> moin
[03:56:27] <Loetmichel> mornin'
[05:34:53] <Swapper_> cmorley: if i go ahead and run 2.5 branch (stable) from http://buildbot.linuxcnc.org/ will that include the patched version och pncconf
[05:35:13] <Swapper_> of pncconf ?
[05:48:37] <jthornton> patched for?
[07:58:50] <Swapper_> fixing a bug with mesa 5i25 + 7i77 and pncconf
[08:37:51] <JT-Shop> my guess is not
[11:18:05] <JT-Shop> crap, my plasma torch is not firing...
[11:56:33] <Swapper_> cmorley: it works with latest from build bot (regarding the pncconf bug)
[12:39:50] <sabotender> can i use a parallel to usb adapter with a cnc router or must there be a parallel port on my computer?
[12:40:25] <archivist> usb parallel port aint gonna work
[12:40:50] <sabotender> i didn't think so
[12:41:53] <archivist> usb allows dead phases for connection detection
[12:42:12] <archivist> device discovery etc
[12:42:57] <sabotender> ah i see. well, PCI parallel port cards are cheap
[12:44:16] <sabotender> because none of my computers have parallel ports :-P
[12:45:40] <CaptHindsight> sabotender: most of the PCI/e to LPT cards work if you connect them directly to stepper drivers
[12:46:48] <CaptHindsight> some have flaky hardware and won't work well connected to a FPGA
[12:47:12] <sabotender> I wonder if express card parallel port would work too :-P
[12:47:27] <sabotender> then I could use my notebook instead
[12:48:13] <Jymmm> laptops have power management which time splice/pause real time operations
[12:48:17] <CaptHindsight> if your notebook has low enough latency, run the test and see
[12:48:28] <sabotender> http://www.amazon.com/StarTech-Parallel-Port-PCMCIA-Card/dp/B000SR2H4W/ref=pd_sim_e_1?ie=UTF8&refRID=1RP04EGNHW4SS1NRFEC0
[12:48:47] <CaptHindsight> so far only a few have been discovered to work fast enough
[12:48:55] <jdh> run the latency test first. doubtful it will work
[12:50:15] <CaptHindsight> it's highly doubtful on that old of a laptop
[12:50:25] <sabotender> wait so I buy the card and then run the latency test?
[12:51:12] <CaptHindsight> run the test before buying anything
[12:51:43] <CaptHindsight> pop in the Livecd and run the latency test
[12:51:57] <sabotender> right, but how do I run the test? what is it called so I can find it on google
[12:52:18] <CaptHindsight> it's in the menu on the Livecd
[12:52:41] <CaptHindsight> LATENCY TEST
[12:53:01] <sabotender> what live cd? a random linux live cd?
[12:54:01] <CaptHindsight> Linuxcnc http://www.linuxcnc.org/index.php/english/download
[12:54:31] <sabotender> oh sweet :-D
[12:55:10] <CaptHindsight> http://linuxcnc.org/docs/html/install/Latency_Test.html
[12:57:30] <sabotender> you will have to forgive me, as I am new-ish to the CNC world. I am getting my first router after careful research
[12:58:17] <sabotender> I am getting the 6040 cnc router
[13:03:26] <archivist> what are you intending to machine on it
[13:05:57] <jdh> heh... 'careful research' and 'getting a 6040'
[13:12:32] <CaptHindsight> sabotender: those are ok for cutting thin or softer materials
[13:12:58] <CaptHindsight> quality is hit or miss
[13:14:13] <CaptHindsight> the only part anodized is sometimes the t-slot so they look pretty rough out of the box
[13:15:40] <CaptHindsight> they mount the motors with a bolt as a spacer, not sure what that is about
[13:16:33] <CaptHindsight> so there is a gap the thickness of the bolts between the face of the motors and the mount
[13:17:13] <CaptHindsight> maybe it's because they don't bother to machine the mount to match the face of the motor
[13:20:19] <IchGuckLive> hi all B)
[13:25:58] <sabotender> CaptHindsight: I doubt I would be cutting anything harder than aluminium
[13:26:26] <IchGuckLive> alu is a tricky thing
[13:26:29] <archivist> aluminium is hard for some machines
[13:26:33] <sabotender> most of my chasis will be plastic, but some of my plans definitely call for metal parts and aluminium will suit just fine
[13:27:00] <IchGuckLive> some hard alu will be more cutable then the cheep chees alu
[13:27:01] <CaptHindsight> anything more than aluminum sheet and you will be disappointed
[13:27:12] <sabotender> archivist: I have seen youtube videos of the 6040 and they cut aluminium just fine
[13:27:44] <CaptHindsight> some of us work with very high precision machines
[13:27:44] <archivist> depends on the ally
[13:28:06] <CaptHindsight> there's cutting and cutting with precision
[13:28:35] <CaptHindsight> some people just expect miracles from budget machines
[13:28:41] <sabotender> http://www.youtube.com/watch?v=K7xkqel2Dq8
[13:28:44] <CaptHindsight> we just want you to be realistic
[13:29:31] <sabotender> that appears to be doing a fantastic job
[13:29:35] <humble_sea_bass> sabo has been here since 10pm last night talking in circles about he is just going to build a machine for next to nothing
[13:29:58] <sabotender> I said I *could* and it was an *option*
[13:30:17] <humble_sea_bass> git 'er done
[13:30:32] <sabotender> you keep saying that like its some clever quip
[13:30:39] <IchGuckLive> so sabotender what is your buged
[13:30:49] <CaptHindsight> budget
[13:31:54] <sabotender> which it isn't. I am doing research and just because you spent thousands on a router doesn't mean I have to. my intentions are realistic and simple. And I shouldn't have to defend my decision. Not all of the inexpensive routers are crap, and I am sorry that your experience has led you to believe it is
[13:31:56] <CaptHindsight> that knob took only 11 hrs on that machine :)
[13:32:19] <IchGuckLive> sabotender: are yoiu in the UK
[13:32:43] <archivist> as a cheap person, I built my own machine
[13:32:51] <sabotender> IchGuckLive: no, I am in the US. my budget is maybe 1.5 - 2k
[13:32:57] <IchGuckLive> archivist as we all do
[13:33:28] <IchGuckLive> sabotender: thats very high
[13:33:32] <sabotender> I don't know why some people in here beilieve that i have to spend 6k just to get a quality machine.
[13:33:39] <IchGuckLive> sabotender: do you got any masies to make parts
[13:33:46] <archivist> sabotender, you dont
[13:34:09] <archivist> I used scrap parts from other machines
[13:34:24] <humble_sea_bass> I think we showed you the fireball v90 and you shat on it because the 600 dollar price tag doesnt includ 120 bux worth of motors
[13:34:25] <sabotender> CaptHindsight and humble_sea_bass seem to believe so, and they get pissy when I show them the possibilities of the cheaper machines.
[13:34:37] <sabotender> humble_sea_bass: and I told you that the v90 is too small
[13:34:45] <sabotender> the 6040 is the size I need
[13:35:05] <CaptHindsight> yikes, is that what you got out of my comments?
[13:35:11] <IchGuckLive> thats a good size
[13:35:21] <IchGuckLive> sabotender: what state are you
[13:36:00] <sabotender> CaptHindsight: yes, I did. because you were saying that those machines absolutely could *not* cut aluminum, and when I show you that your assumptions are false, you have another negative quip to throw in
[13:36:25] <humble_sea_bass> hah
[13:36:28] <sabotender> its just exhausting filtering though the bs, when I am trying to have a civilised conversation is all
[13:36:47] <humble_sea_bass> you can cut aluminum by pissing on it, you're just gonna have to let it rip for a while
[13:37:10] <IchGuckLive> did you lok for a toolshop next to your location that buidas this mashines
[13:37:17] <CaptHindsight> sabotender: I said those things?
[13:37:41] <CaptHindsight> sabotender: are you a native English speaker?
[13:38:07] <IchGuckLive> 6040 is made all over the USA
[13:38:23] <sabotender> IchGuckLive: yeah I noticed
[13:38:36] <IchGuckLive> by the way im in Germany
[13:39:15] <IchGuckLive> so lets get mire detailed you need at least a 8025 frame set
[13:39:45] <IchGuckLive> you need to cut good parts a ballscrewLeadscrew dor all 3 axis
[13:40:47] <IchGuckLive> and a 3Nm 450Oz steppers
[13:40:50] <sabotender> http://www.youtube.com/watch?v=Ng9LCBZK89g there is another pretty cool vid of the 6040
[13:41:19] <IchGuckLive> i asume to go for leadshine M880A and 80V
[13:41:33] <sabotender> IchGuckLive: wait, what are you talking about again?
[13:41:41] <IchGuckLive> this gives you a very good performence
[13:41:57] <jdh> I have also researched 6040's and will be getting one anyway.
[13:42:12] <IchGuckLive> a timingbelt gearsystem at 20/25
[13:42:33] <CaptHindsight> lol
[13:42:53] <IchGuckLive> sabotender: http://foengarage.de/gears2.html
[13:43:40] <IchGuckLive> this is why you need the gear to get the 400steps of your stepper into a good performence
[13:44:12] <sabotender> oh nice :-D
[13:44:13] <IchGuckLive> in metric you are at the best milling performence on this setup
[13:44:57] <IchGuckLive> and for milling you only need parport so electronics charge is 50USD
[13:45:17] <jdh> sabotender: you shoulc get teh carving-cnc 6040 mainbody, a G540 + 48v PSU + spindle/vfd from ebay
[13:45:26] <IchGuckLive> with your high budget you can go mesa 5i25/7i76 and have best ever choce
[13:45:30] <jdh> then let me know how it works before I buy the same.
[13:46:05] <jdh> Ich: you think mesa really adds anything if you are not at p-port speed limits?
[13:46:59] <IchGuckLive> this is how capt kthk will buy you the mashine
[13:47:01] <IchGuckLive> http://s.taobao.com/search?q=carving-cnc+6040&app=detail
[13:47:16] <IchGuckLive> 700USD complede
[13:50:46] <CaptHindsight> humble_sea_bass: http://abclocal.go.com/wabc/story?section=news/local/new_york&id=9462035
[13:51:00] <IchGuckLive> sabotender: its the JapanChina amazon
[13:51:16] <sabotender> give me a moment, I am trying to make bkfst. I am not ignoring you lot
[13:52:09] <JT-Shop> anyone fix my plasma while I was gone?
[13:52:25] <IchGuckLive> im the plasma fixer ;-)
[13:52:42] <IchGuckLive> as now maybe 15 plasma owner call here to fix
[13:52:43] <CaptHindsight> did you tun it of and on again?
[13:53:19] <IchGuckLive> look an the Gnd Chain if it still grounded
[13:53:20] <JT-Shop> yes
[13:53:28] <humble_sea_bass> cap i saw that
[13:53:37] <humble_sea_bass> very exciting@
[13:54:01] <humble_sea_bass> the anti-vaxx crowd is a treat
[13:55:04] <IchGuckLive> CaptHindsight: do you got access via your company towards tabao
[13:55:18] <CaptHindsight> IchGuckLive: same as you
[13:55:52] <CaptHindsight> IchGuckLive: what helps is having locals deal with better pricing or problems
[13:55:56] <IchGuckLive> i only go a person in HK that tryes to get the best shiment
[13:57:44] <CaptHindsight> I've stood there for an hour watching them haggle over <$1 for one part
[13:57:59] <IchGuckLive> agree on that
[13:58:20] <IchGuckLive> L297 driver boards for 1USD
[13:58:23] <humble_sea_bass> I've never used taobao
[13:59:25] <CaptHindsight> Chinese Amazon but more difficult with returns
[13:59:26] <IchGuckLive> best ship i reatched order 9am Friday Berlin time Delivery from HK via airmail on thusday 10am
[13:59:33] <humble_sea_bass> how is it compared to aliexpress
[13:59:54] <CaptHindsight> taobao is what the locals use
[14:00:03] <CaptHindsight> aliexpress is for exports
[14:00:04] <humble_sea_bass> the shippers from aliexpress use the slow boat so it is like two weeks to nyc at least
[14:00:46] <IchGuckLive> 2weeks is ok for our parts almost
[14:01:14] <humble_sea_bass> but i need those DIN connectors NOW
[14:01:22] <CaptHindsight> EMS from China is under a week
[14:01:25] <IchGuckLive> but as capt said it may be some fake parts
[14:01:33] <humble_sea_bass> (by need I mean want)
[14:02:02] <IchGuckLive> i got a M880a delivery that dident make the timing
[14:02:04] <CaptHindsight> Fedex and DHL from China is ~2 days
[14:02:29] <humble_sea_bass> Fedex costs a fortune usually on ali
[14:02:38] <IchGuckLive> agree on that on 40USD charge
[14:02:53] <CaptHindsight> Fedex and DHL to China is 3-5 days, it's always faster out of China than into China
[14:04:17] <sabotender> alright! I have returned, with food :-D
[14:04:22] <sabotender> let me scroll up
[14:04:36] <IchGuckLive> sabotender: no need internal discussion
[14:05:08] <sabotender> jdh: I wanted to go that route, but I don't know how to differentiate a good stepper and spindle from a poor one.
[14:05:20] <IchGuckLive> sabotender: what state are you
[14:05:46] <IchGuckLive> lets find one in your driving range
[14:06:13] <sabotender> IchGuckLive: I prefer to order my loot online
[14:06:28] <sabotender> I don't mind the shipping times
[14:06:32] <IchGuckLive> ok up to you
[14:06:34] <humble_sea_bass> "loot"
[14:07:39] <sabotender> humble_sea_bass doesn't seem to like that word. Fine. Stuff. Merchandise. Things. Equipment. Parts. Components. Items.
[14:08:00] <humble_sea_bass> I was playing Zork
[14:08:13] <humble_sea_bass> i have no idea what you're talking about
[14:08:25] <IchGuckLive> what experiency in electronic mantainance do you got sabotender
[14:08:50] <sabotender> IchGuckLive: great. I have an ee degree. Recent graduate.
[14:09:10] <IchGuckLive> ok so 500USD for the main 6040 frame
[14:09:24] <IchGuckLive> and build your Alu mill on your own
[14:09:50] <IchGuckLive> going the way i anounced earlyer
[14:10:17] <CaptHindsight> 50F going to the beach!
[14:10:46] <IchGuckLive> CaptHindsight: surfe boards are outside torrance ca
[14:10:49] <sabotender> right, and buy the other parts separately.
[14:11:07] <sabotender> that is what jdh was saying
[14:11:29] <CaptHindsight> humble_sea_bass: any developments on the reader?
[14:11:47] <IchGuckLive> 80V leadshine M880 and a 2005 ballscrew setup
[14:12:11] <IchGuckLive> sabotender: at 450+ Oz steppers
[14:13:22] <humble_sea_bass> http://www.youtube.com/watch?v=i9GBZ2qNvDs
[14:13:46] <humble_sea_bass> i got over the flu so as of this evening I'll get to work
[14:21:51] <IchGuckLive> im off BYE have a nice milling suturday its rainy here so i will run all 3 mills tomorrow cutting wood boards
[14:21:54] <CaptHindsight> humble_sea_bass: I'm building some paste extruders now
[14:22:39] <CaptHindsight> humble_sea_bass: they can print the polymers
[14:24:43] <humble_sea_bass> I'd really like to get more involved with that sort of equipment
[14:25:30] <humble_sea_bass> is that what the new leadshine driver is for?
[14:25:51] <jdh> good stepper is easy to find.
[14:26:43] <CaptHindsight> humble_sea_bass: sort of, I just wanted to try it for some low end stepper driven printers
[14:27:09] <CaptHindsight> i just don't want any warranty or support issues for 2+ years
[14:30:31] <sabotender> i think he means 'a' 450+ oz stepper, not 'at'
[14:31:02] <jdh> get them from keling
[14:31:13] <jdh> and get a g540 for simplicity
[14:32:35] <humble_sea_bass> [M f6the g540 + kellings make the most annoying noise on idle
[14:33:11] <CaptHindsight> the keilings are all leadshines
[14:34:43] <humble_sea_bass> yeah. that was a revelation
[14:35:04] <jdh> all cheap drives look like leadshines. or are they clones
[14:35:36] <CaptHindsight> humble_sea_bass: I have to find a balance between driving voltage and deflection
[14:36:34] <CaptHindsight> 2-4KV drive is going to make layout more difficult, <1KV with 0.5mm deflection is the goal
[14:37:21] <sabotender> is it my imagination or are those 450 Oz steppers 300 USD a pop?
[14:38:50] <sabotender> I don't know. maybe that is a size specification
[14:39:48] <humble_sea_bass> you think you'd get any arcing between hi and lo pins
[14:40:37] <CaptHindsight> it's very low current, and it's insulated by the same or similar material
[14:41:28] <sabotender> jdh: can you give me more information about this '450 oz' whatever?
[14:41:34] <sabotender> I can't find much about them on google
[14:41:40] <CaptHindsight> that's the down side of many of the polymers, the voltage required
[14:42:35] <CaptHindsight> living muscle is low voltage
[14:44:07] <CaptHindsight> http://www.automationdirect.com/adc/Shopping/Catalog/Motion_Control/Stepper_Systems/Stepper_Motors_-z-_Cables/STP-MTR-34066
[14:44:27] <CaptHindsight> 434 oz-in $111.00
[14:45:11] <CaptHindsight> 861 oz-in $140.00 http://www.automationdirect.com/adc/Shopping/Catalog/Motion_Control/Stepper_Systems/Stepper_Motors_-z-_Cables/STP-MTRH-34097
[14:48:38] <humble_sea_bass> tragic magic
[14:51:58] <sabotender> i'll have to choose a different stepper because i cant find any info on the ones there were suggested to me
[14:52:28] <humble_sea_bass> what was suggested to you
[14:52:47] <humble_sea_bass> Leadshines?
[14:52:49] <sabotender> a 450 oz, whatever that is
[14:53:14] <humble_sea_bass> yeah get the whatever that ises, those are teh best
[14:53:39] <sabotender> O_o
[14:54:54] <sabotender> I'll ask someone else
[14:57:15] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/nema-34/nema-34-high-torque-stepper-motor-single-shaft NEMA34 465 oz-in
[14:58:29] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/nema-34/nema34-1805ozin-8-8a-cncstepper-motor NEMA34 1805oz/in
[14:58:30] <sabotender> OH the WEIGHT
[14:59:01] <sabotender> he was referring to the weight
[14:59:46] <CaptHindsight> http://www.aqua-calc.com/what-is/linear-density/ounce-per-inch
[14:59:51] <archivist> oz in is the torque
[15:00:04] <sabotender> ah! even better!
[15:00:39] <sabotender> I did not know this since ive never actually played with a stepper motor before
[15:00:51] <CaptHindsight> http://www.physics.uoguelph.ca/tutorials/torque/Q.torque.intro.html
[15:01:04] <sabotender> I know what torque is
[15:02:22] <CaptHindsight> https://www.grc.nasa.gov/www/k-12/airplane/torque.html I wish we had this when i was a kid
[15:03:09] <Loetmichel> you americans and your strange units ;-)
[15:03:17] <CaptHindsight> referring to the website, we had torque :)
[15:03:24] <sabotender> archivist: thank you very much for clarifying things
[15:03:56] <sabotender> so any stepper motor that provides at LEAST that much torque would be suitable
[15:05:57] <archivist> you need enough torque to avoid lost steps but over specifying gives a slower maximum rpm for the stepper
[15:06:16] <archivist> so....depends
[15:06:35] <sabotender> ah, gotta find that sweet spot
[15:06:49] <humble_sea_bass> like the 10 crack commandments
[15:06:59] <Loetmichel> archivist: that can be cured with more voltage ;-)
[15:07:09] <sabotender> so I can expect to spend ~210 on a trio of good steppers
[15:07:35] <archivist> not cured but improved
[15:07:52] <humble_sea_bass> yes sabo, 3*70 dictates that to be the case
[15:07:52] <sabotender> and that g540 is 300 usd
[15:08:31] <archivist> I use the leadshine drives
[15:09:51] <CaptHindsight> sabotender: please post pics or vids when you're done
[15:10:09] <CaptHindsight> it's always interesting to see the final results
[15:10:52] <sabotender> CaptHindsight: I will definitely, but I want to make sure I have a complete parts list before I start buying stuff
[15:11:05] <humble_sea_bass> http://image.thefabricator.com/a/safety-in-jet-cutting-jet-cutting-hazard-sign.jpg
[15:12:01] <sabotender> the frame itself is 838 usd, and i have to stay within budget for the rest of the stuff
[15:12:10] <CaptHindsight> for even fingers place hand into the jet
[15:12:20] <CaptHindsight> what i got out of it anyway
[15:13:11] <humble_sea_bass> finger hemming
[15:14:04] <sabotender> wait, what?
[15:17:55] <sabotender> archivist: what does 'phase' refer to?
[15:18:09] <sabotender> a complete revolution?
[15:18:24] <humble_sea_bass> you know when kids become teenagers
[15:18:30] <archivist> relation between two signals
[15:18:33] <humble_sea_bass> and they all of a sudden hate their parents
[15:19:03] <humble_sea_bass> of when they start wearing all black
[15:20:04] <archivist> often stepper coils are referred to in that way as they are wound at a magnetic angle to each other
[15:20:19] <sabotender> archivist: ah i see. so would it make any difference if I got a 2 or 3 phase stepper drive?
[15:20:58] <archivist> it matters, get matching drivers
[15:21:27] <sabotender> right, they would all be the same model
[15:21:44] <sabotender> oh the driver
[15:21:45] <archivist> most stuff is bipolar 2 phase
[15:22:10] <sabotender> so I should focus on the 2 phase steppers
[15:24:23] <PCW_> 2 phase is by far the most common (though for example Tormach has changed to 3 phase step motors on their latest)
[15:27:24] <sabotender> i see. is there a good resource that has some kind of checklist of the items i need to complete the mainbody?
[15:27:53] <archivist> the important thing is match the driver to the steppers you want, or the other way round
[15:29:55] <sabotender> that makes sense, but im talking about like the bolts and nuts to secure the steppers, wires and connectors, etc etc
[15:30:29] <CaptHindsight> http://www.omega.com/prodinfo/stepper_motors.html
[15:30:29] <humble_sea_bass> pffft
[15:31:15] <Jymmm> sabotender: Whatever you plan or budget for, triple it for actual expenses.
[15:31:35] <sabotender> Jymmm: salami.
[15:31:46] <archivist> CaptHindsight, that is a broken web page
[15:32:05] <CaptHindsight> http://www.engineersgarage.com/articles/stepper-motors
[15:32:22] <archivist> sent my browser silly
[15:32:44] <CaptHindsight> maybe some fun with JS or cookies
[15:33:21] <sabotender> very informative.
[15:33:38] <archivist> I think so I heard the disk drive get busy and the display was odd, I killed it quick
[15:34:16] <CaptHindsight> archivist: omega.com link?
[15:34:34] <archivist> yes
[15:35:33] <CaptHindsight> only 3 trackers
[15:36:07] <CaptHindsight> not my site but I just tried it with firefox and chrome without issues
[15:36:24] <archivist> yes but how busy and how much memory is that page using, there are some bad js web2 things about
[15:37:42] <CaptHindsight> http://homepage.cs.uiowa.edu/~jones/step/
[15:38:04] <sabotender> archivist: do you have any resources where I could get this information?
[15:38:48] <archivist> someone is feeding you resources at the moment :)
[15:39:06] <sabotender> wait, what?
[15:39:20] <sabotender> it mustve gone right over my head. let me check
[15:40:53] <archivist> and my fav http://www.micromo.com/microstepping-myths-and-realities.aspx
[15:42:41] <sabotender> oh but thats not what i am looking for
[15:43:14] <humble_sea_bass> we require more resources
[15:43:24] <sabotender> I am an electrical engineer, not a mechanical, so many of mechanical concepts baffle me.
[15:43:46] <sabotender> I meant making sure I have all the parts to construct a complete router
[15:43:50] <humble_sea_bass> it is all tubes man
[15:44:30] <sabotender> since it was suggested that I just buy the mainbody and get the other parts separate. I am trying to find info about what other 'parts' i need
[15:44:49] <humble_sea_bass> you focus on a subsystem, strt gettin' 'er done till you can't get 'er done no more because something is missing
[15:44:57] <sabotender> I know that I need a stepper driver, 3 stepper motors, and a spindle. I need the software too, but I know I am missing stuff
[15:45:23] <sabotender> like...bushings and washers and bolts and nuts and other stuff that makes me dizzy thinking about
[15:46:21] <sabotender> humble_sea_bass: that's a craptastic way to go about something. I hate starting a project just to discover that something is missing
[15:46:25] <sabotender> I like to be prepared
[15:47:45] <CaptHindsight> whoever suggested that probably didn't realize how uncomfortable you are with it
[15:48:12] <sabotender> especially when I am going to be spending as much money as I am going to
[15:48:50] <archivist> I have made kits and stuff from scratch, not sure either is "best"
[15:50:35] <humble_sea_bass> i actually keep stock of useful things so I just go to my tool box drawers and I continue to get 'er done
[15:51:42] <archivist> I do feel for the run out of x sized screw error
[15:52:20] <humble_sea_bass> whatever you budget, tripple it
[15:52:50] <sabotender> sausage.
[15:52:54] <humble_sea_bass> the incidental costs are 3x whatever number you come up with
[15:53:21] <CaptHindsight> no more feeding racehorses
[15:53:30] <sabotender> thats why it might be best for me to get a complete set
[15:54:40] <archivist> do you have any manual lathe and drill etc
[15:55:00] <sabotender> no lathe but i have a drill
[15:55:23] <humble_sea_bass> get a rep rap, I hear those are real sweet machines and come with everything you ever needed in a box with ikea like illustrations
[15:55:48] <archivist> reasonable motor mounts need a lathe or mill so get ready made
[15:56:07] <sabotender> ikea instructions are not very good
[15:56:22] <humble_sea_bass> bite your tongue
[15:56:51] <sabotender> and their stuff is too expensive for the quality offered
[15:57:06] <humble_sea_bass> http://global3.memecdn.com/Ikea-instructions-to-babby_o_68360.webp
[16:07:13] <Swapper_> anyone know how to get what encoder is on what block in the 7i77 ?
[16:07:44] <Swapper_> it says Muxed encoder 0 in pncconf but i dont get what pins ?
[16:09:05] <sabotender> archivist: so you dont think this set is satisfactory: http://www.ebay.com/itm/PROFESSIONAL-3-AXISES-6040-CNC-ROUTER-ENGRAVER-DRILLING-MILLING-MACHINE-p9-/170795467640?pt=LH_DefaultDomain_0&hash=item27c4340378
[16:11:56] <archivist> sabotender, depends what one is intending to make
[16:13:52] <archivist> but I do wonder why at that price they cant be bothered to get the text etc right
[16:14:24] <sabotender> archivist: what? just simple stuff! chassis for my electrical projects, maybe etch PCBs, some sheet aluminium milling
[16:14:33] <sabotender> yeah i was looking at that
[16:16:07] <archivist> and there are reports of having to align the things when they arrive
[16:16:20] <sabotender> the chassis are important
[16:16:47] <sabotender> whats wrong with aligning? hardware aligning or software?
[16:17:22] <archivist> the chassis alignment I am talking about, out of square
[16:17:41] <sabotender> you mean..its warped?
[16:17:45] <sabotender> lop-sided?
[16:18:03] <archivist> that picture does not show the rail mounting method either
[16:19:22] <sabotender> heh. long life circle
[16:21:00] <humble_sea_bass> what engineering school did you go to
[16:21:07] <sabotender> im not sure what that means, but it sounds important (rail-mounting method)
[16:21:24] <archivist> that and an arrow to the gantry and calling it an engraver
[16:21:33] <sabotender> hehe
[16:22:40] <archivist> the round bar types are either end mounted (liable to chatter/vibrate) or full length supported (ok)
[16:25:02] <sabotender> ah i see
[16:25:47] <sabotender> soo...that's a bad set :-(
[16:55:22] <PCW_> Swapper_ 7I77 manual page 4 shows the encoder numbers
[16:56:24] <PCW_> (and pages 7-8)
[17:14:42] <Deejay> gn8
[18:20:08] <andypugh> So, what machining sequence for these? I really can't decide. http://imagebin.org/299390
[18:20:18] <andypugh> (note that the edges are not parallel)
[18:26:05] <andypugh> I think the best plan might be to part-cut the profile with the flat side up, do the convex radii, then finish the cutting-put, them put them in a fixture logated by the big oval hole.
[18:27:16] <andypugh> (slightly awkwardly they are mirror-images in their taper)
[18:29:39] <toastyde1th> i'd cut all the features on the non-sunk side first
[18:29:49] <toastyde1th> cut the taper next
[18:29:53] <toastyde1th> then lay it flat and do everything else
[18:30:25] <andypugh> How to hold it down for the internal profiling?
[18:30:31] <toastyde1th> in a vise?
[18:30:37] <andypugh> They taper
[18:30:39] <Loetmichel> glue ;-)
[18:30:48] <toastyde1th> cylinder
[18:31:10] <andypugh> Glue might be the way.
[18:31:25] <toastyde1th> i'd either cut soft jaws or use a pin
[18:31:36] <andypugh> I used to use sticky wax all the time when making TEM samples.
[18:32:12] <andypugh> I need to make one pair. I might make 6 pairs, in case any other owners of 1921 Ner-A-Cars want some...
[18:32:29] <toastyde1th> instead of a pin you can also use a chunk of wood and just file a radius into it
[18:32:31] <andypugh> So soft-jaws might be a bit much.
[18:32:35] <Loetmichel> andypugh: https://www.youtube.com/watch?v=o53RsosYwGg
[18:32:36] <toastyde1th> pretty standard technique to hold tapered parts
[18:33:25] <Loetmichel> CA is a wonderful thing
[18:33:29] <andypugh> Loetmichel: I see that your CAM puts in loads of annoying Z-moves too :-)
[18:33:46] <JT-Shop> yea, the log splitter works!
[18:34:00] <Loetmichel> after milling: give it a tap with a lead mallet-> done ;-)
[18:34:03] <andypugh> Just in time for summer!
[18:34:07] <Loetmichel> andypugh: cam?
[18:34:11] <Loetmichel> thats BoCNC
[18:34:32] <Loetmichel> a little freeware that can convert 2d plots and dxf to gcode
[18:34:46] <Loetmichel> depth by pen number
[18:34:46] <andypugh> OK, so why all the Z-action?
[18:35:15] <Loetmichel> bedause it does slices if tolt that it can mill only so deep in one turn
[18:35:17] <toastyde1th> Also, another useful thing to have is a machine jaw with a spherical back to it that sits in a spherical pocket, so it can hold all sorts of irregular parts
[18:35:33] <Loetmichel> why it pulls out between two turns: no idea, ask the programmer ;_9
[18:36:03] <JT-Shop> well spring is a good time to harvest dead standing trees and split them
[18:36:14] <JT-Shop> gotta beat the ticks and chiggers
[18:36:31] <andypugh> This stuff is probably useful, use heat to fix and heat to release: http://www.lakeside-products.com/html/cement.html
[18:37:43] <andypugh> Though I ended up using http://www.universalphotonics.com/Portals/0/TechDatas%5CwaxquartzstickyTD.pdf which has the nice feature of coming off cleanly with turpentine (I couldn't afford to het my samples by the time they were 100um thick)
[18:44:18] <JT-Shop> what do you use them for?
[18:44:57] <andypugh> http://link.springer.com/article/10.1007/BF00275452
[18:45:33] <andypugh> By lucky coincidence, the very first paper of 1993
[18:46:37] <andypugh> So, setting 100um dia fibres in epoxy then mechanically polishing to 10um. Then ion-beam milling to 0.5um.
[18:49:49] <andypugh> But.. The waxes are generally aimed at mounting geological specimens etc.
[18:56:57] <andypugh> Methinks this chap needs to get the hang of tool geometry so that he isn't filing after machining every time: http://www.homemodelenginemachinist.com/f25/all-about-wax-chucks-15752/
[19:14:44] <cmorley> Swapper_: Yaay! Thanks for the report on pncconf.
[19:45:21] <Tom_itx> andypugh, another way to hold them which may not be best would be to profile some softjaws to hold them
[19:45:41] <andypugh> I don't have anything to take soft jaws
[19:46:04] <andypugh> (other than the 10" Kurt that I ought to get rid of as it is bigger than the table)
[19:46:10] <Tom_itx> then you should be able to finish the bottom complete without moving fixture bolts
[19:46:36] <Tom_itx> we used soft jaws alot for odd parts
[19:46:44] <Tom_itx> profile it right in the jaws
[19:47:26] <Tom_itx> another way would be to use some of those offcenter roller clamps on a flat piece of aluminum
[19:47:44] <Tom_itx> or some others that actually push down as they clamp
[19:47:48] <Tom_itx> i forget what they're called
[19:47:55] <humble_sea_bass> 1screwless?
[19:48:24] <Tom_itx> there's all sorts of odd clamps available like that
[19:48:49] <Tom_itx> probably not something you want to stop to find for this
[19:49:17] <andypugh> I am looking at these: http://www.ebay.co.uk/itm/MILLING-CLAMPS-/191095326221?pt=LH_DefaultDomain_3&hash=item2c7e2b460d
[19:49:46] <andypugh> But no hint what the T-slot size is.
[19:49:57] <Tom_itx> yeah
[19:50:17] <andypugh> Or these: http://www.ebay.co.uk/itm/New-Vertex-T-slot-set-4pc-clamps-milling-drilling-direct-from-Myford-ltd-/191091068226?pt=LH_DefaultDomain_3&hash=item2c7dea4d42
[19:50:25] <Tom_itx> my bud started using special fixture mounts on an aluminum plate to eliminate all those frustrations
[19:50:36] <Tom_itx> able to hold all sorts of fixture clamps etc
[19:50:48] <Tom_itx> that does look like what i was suggesting though
[19:50:56] <andypugh> If I planned on making a bazillion it would be different.
[19:50:57] <Tom_itx> or similar at least
[19:52:55] <Tom_itx> if you held it in visejaws, you'd wanna wait on the exterior radius
[19:53:03] <Tom_itx> which would add an op
[19:53:36] <Tom_itx> otherwise you'd be pinching the part you are milling away
[19:54:07] <Tom_itx> it might still work depending how deep the softjaws are cut
[19:54:21] <andypugh> I still need to work out how to beat the CAM into submission.
[19:55:04] <Tom_itx> if you get stuck i could give it a whirl
[19:55:34] <Tom_itx> it's been a while but i try to keep in shape with my cad cam
[19:56:24] <Tom_itx> looks like you need a ballnose for sure on part of it
[19:56:43] <Tom_itx> some could be done with a bull depending on what you have available
[19:56:47] <andypugh> Well, the thing is that I don't really want to just do a depth raster. I want to pocket out the inner, then draw in the radii with a ball-nose. But the paths are not closed, because it tapers to nothing.
[19:59:10] <Tom_itx> were you gonna ballnose the 2 edges that taper?
[19:59:32] <andypugh> I hadn't decided. I am not too proud to use a file :-)
[19:59:37] <Tom_itx> for production purposes it would be quicker that way but one or two off you may wanna do something different
[20:00:55] <Tom_itx> what's it for?
[20:01:00] <Tom_itx> if you said... i came in late
[20:02:15] <Tom_itx> i assumet the bottom is flat too
[20:02:40] <Tom_itx> something i learned not to do in aircraft parts
[20:02:57] <andypugh> Parts 103 and 104 here: http://www.geutskens.eu/neracar/frame_assy.htm
[20:03:56] <andypugh> The bottom is flat. It isn't flat in the original. but I plan on bending it to siut the frame.
[20:06:40] <Tom_itx> another restoration project?
[20:09:30] <andypugh> Maybe the same one?
[20:10:54] <andypugh> I currently have the Rivett lathe and the Ner-a-Car. So only two projects.
[20:11:29] <Tom_itx> would you do the pockets undersize the radius distance then let the ballnose finish it out?
[20:11:45] <andypugh> That was my plan, yes
[20:11:56] <Tom_itx> probably 6mm cutter?
[20:12:01] <Tom_itx> hard to judge size there
[20:12:24] <andypugh> Yes. The radius seems to be 3/32"
[20:13:16] <Tom_itx> or are you using inch cutter sizes?
[20:14:00] <andypugh> I am using what I have. The parts are imperial / Whitworth / BA but my tooling is largely metric.
[20:19:44] <Connor_iPad> What's up?
[20:20:15] <andypugh> It's been a long day, was up at 0530, day trip to germany, and back home. It's 0100 now and I think I am going to climb the wooden hills.
[20:20:25] <Tom_itx> heh
[20:20:30] <andypugh> Night all.
[20:20:34] <Tom_itx> night andy
[20:20:46] <Connor_iPad> Gnight Andy
[20:31:48] <MrHindsight> http://www.youtube.com/watch?v=odJxJRAxdFU Three-Dimensional Mid-Air Acoustic Manipulation
[21:10:55] <humble_sea_bass> that's pretty
[22:43:20] <sabotender> moo
[22:43:22] <sabotender> hello all
[22:43:52] <sabotender> awwe, Connor_iPad is gone :-(
[22:43:57] <sabotender> I was going to ask him questions!
[22:48:38] <zeeshan> http://vietnam.craigslist.org/for/4372477162.html
[22:48:39] <zeeshan> LOL
[22:48:51] <zeeshan> who the hell sells an airplane on kijiji
[22:49:00] <zeeshan> on top of that its the missing airplane ;p
[22:49:34] <sabotender> lol (this includes all the snacks on the plane)
[22:50:01] <sabotender> like that is a real important buyer's point of interest
[22:52:10] <sabotender> oh lord, it's the missing aeroplane?
[22:52:23] <Connor> huh ?
[22:52:25] <sabotender> zeeshan: what sort of mill/router do you have over there?
[22:52:35] <sabotender> oooo Connor!
[22:52:49] <sabotender> I tried to highlight your ipad nick and noticed it wasn't there
[22:53:00] <sabotender> I didn't bother to check your main :-P
[22:53:06] <Connor> Yea.. having issues with freenode tonight
[22:53:26] <sabotender> ah I see. well mind if I ask you a few questions?
[22:53:32] <Connor> What's up?
[22:53:40] <zeeshan> connor is famous
[22:53:40] <zeeshan> :D
[22:53:48] <PetefromTn_Andro> Still have not received my damn bearing...
[22:53:54] <zeeshan> guess what i got today?!?!
[22:53:57] <zeeshan> my kennedy tool boxes
[22:54:04] <Connor> zeeshan: Cool
[22:54:05] <zeeshan> so i looked up the prices for each one on enco
[22:54:08] <zeeshan> total $2322
[22:54:09] <Connor> PetefromTn_Andro: Damn dude.. that sucks.
[22:54:15] <sabotender> Connor is more knowledgeable than I when it comes to CNC mills/and routers
[22:54:16] <zeeshan> i got em for 1200
[22:54:21] <zeeshan> and got a shit load of machinist tools
[22:54:24] <zeeshan> some of which i dont even know how to use
[22:54:29] <zeeshan> like the bore gauge
[22:54:30] <zeeshan> lol
[22:54:40] <zeeshan> need to find a youtube video =/
[22:54:53] <Connor> PetefromTn_Andro: Remember, wife kicking me out of the house tomorrow. :)
[22:54:57] <sabotender> remember when it was suggested that I get the 6040 mainbody and get the spindle + stepper motor + driver separately?
[22:55:07] <Connor> yea
[22:55:28] <sabotender> well, what other stuff would I need to get to assemble the complete router?
[22:55:36] <PetefromTn_Andro> Oh yeah you coming over again?
[22:55:49] <Connor> PetefromTn_Andro: Either that, or I roam the streets.. :)
[22:56:17] <PetefromTn_Andro> You don't strike me as the street roamin' sort...
[22:56:18] <Connor> sabotender: You'll want some 18 gauge 4 conductor wire (stranded, not solid) Alarm wire works good.
[22:56:46] <Connor> You'll want a PC with Para port and a Breakout board.. or a Mesa Card..
[22:56:48] <sabotender> I can assemble stuff without a problem if I have the instructions for it, but I am not mechanically inclined otherwise. I am an electrical engineer. I don't know much about cogs and sprokets and washers and stuff
[22:57:15] <Connor> Depending on what you end up getting, you might need couplers..
[22:57:52] <Connor> You can use the super cheap aluminum ones that look like they've been spiral cut.. but, they can break due to stress fractures..
[22:58:03] <sabotender> http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html <-- that was suggested
[22:58:07] <Connor> I'm on my second set on my DIY jobber
[22:58:17] <Connor> Yea..
[22:58:21] <Connor> I would look at this one.
[22:58:30] <sabotender> and some leadshines, but I can't find the prices for the leadshine stepper motors
[22:58:39] <Connor> http://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver/3-axis-dsp-based-digital-stepper-drive-max-60-vdc-6-0a
[22:58:39] <humble_sea_bass> infinite loop
[22:58:58] <humble_sea_bass> every 10 hrs, same old same old
[22:59:00] <Connor> With that, you don't need a Break Out board.
[22:59:06] <sabotender> I think they said motor mounts, but the mounts need spacers and nuts and bolts to hold it together right?
[22:59:08] <Connor> humble_sea_bass: What?
[22:59:19] <sabotender> ignore him, he has been trolling me all day
[22:59:36] <PetefromTn_Andro> LMAO...
[22:59:48] <Connor> Not sure.. again, depends on what the frame only comes with.
[23:00:02] <Connor> You in the US?
[23:00:09] <sabotender> yeah I am
[23:00:33] <Connor> okay. The steppers that automationtech sells are nice too..
[23:00:42] <Connor> no complaints and they are what they say they are.
[23:00:55] <Connor> Were you getting the 6040 base from ?
[23:01:04] <sabotender> um...let's see
[23:01:24] <sabotender> http://www.carving-cnc.com/accessories/cnc-router-mainbody/6040mainbody.html
[23:01:58] <sabotender> I'm getting the 838 USD option as those steppers appear suspect
[23:02:52] <sabotender> now, I am assuming that is a good price for the base
[23:02:55] <Connor> spend the extra 61 and get the steppers they have.. because it'll come with the motor mounts too
[23:03:13] <sabotender> really? are you sure it would be okay?
[23:03:30] <Connor> That, or try to make your own..
[23:03:53] <sabotender> well I suppose I could get those and if they aren't up to snuff I can buy different ones later
[23:04:00] <Connor> and if you don't have a lathe, or a mill, it might be hard.. only other way would to be used pipe.. and use really long bolts.. and that's not as good.
[23:04:13] <sabotender> (and make the mounts with the assembled router)
[23:04:32] <Connor> Well.. I'm saing, spend the extra $61.00 and get the 2nd option WITH the steppers, ditch the steppers, keep the mounts, and use a different set of steppers..
[23:04:48] <sabotender> oh dah, you are right
[23:04:57] <Connor> those are standard nema 23 mounts.
[23:05:26] <sabotender> so that means all I would need is the driver and the spindle, right?
[23:05:28] <Connor> NO info at all on what steppers those are..
[23:05:42] <Connor> yea.. Again, http://www.automationtechnologiesinc.com/
[23:05:46] <sabotender> that's why I used the word suspect
[23:05:50] <Connor> they have the MX3660 and spindles..
[23:06:44] <zeeshan> hey connor
[23:06:49] <Connor> yea
[23:06:53] <zeeshan> you've looked into digital probes before right?
[23:07:00] <Connor> Yes.
[23:07:05] <zeeshan> dude for my mill
[23:07:11] <zeeshan> i'm thinking i kind of want to do inspection on it too.
[23:07:14] <sabotender> oooh I want that milling spindle
[23:07:20] <zeeshan> ie mount an engine block
[23:07:20] <Connor> http://www.automationtechnologiesinc.com/products-page/cnc-spindle
[23:07:30] <zeeshan> and do multiple measurements on the bore to get a bore profile
[23:07:34] <zeeshan> (egg shape, taper bore etc)
[23:07:57] <zeeshan> is the digital probe accurate enough?
[23:08:10] <zeeshan> i've read somewhere its accurate to 0.0005"
[23:08:13] <Connor> zeeshan: That's a loaded question.
[23:08:27] <Connor> That depends on the machines accuracy as well as the probes.
[23:08:41] <zeeshan> assume the machine accuracy is like 0.0001"
[23:08:41] <zeeshan> :P
[23:09:02] <Connor> yea.. Most hobby machines are going to be doing good to get 0.0005"
[23:09:10] <sabotender> Connor: which spindle do you recommend that I get? or what should I look out for?
[23:09:17] <zeeshan> 0.0005" is pretty decent
[23:09:28] <zeeshan> i'm just wondering if the probes add major error
[23:09:30] <Connor> sabotender: First, make sure it fist the motor mount. :)
[23:09:36] <zeeshan> or are within the same error as the machine error
[23:09:38] <Connor> zeeshan: Shouldn't add much..
[23:09:50] <zeeshan> writing a cmm based program wouldnt be too hard
[23:09:51] <sabotender> Connor: I should't make them fight each other :-P
[23:09:52] <zeeshan> i'd think
[23:10:01] <Connor> depends on how well you calibrate it..
[23:10:07] <CaptHindsight> on a router with 0.004" accuracy
[23:10:14] <Connor> fits no fist
[23:11:17] <Connor> sabotender: Collet size, water cooled, VFD..
[23:11:32] <PetefromTn_Andro> Its like fantsyland in here tonight hehehe
[23:11:34] <Connor> or, you can go cheaper, and use a Bosh colt with a superpid...
[23:11:35] <sabotender> okay water cooled means i will need to get a pump as well
[23:11:45] <Connor> yea.
[23:12:04] <sabotender> I would like to stay around 1.5k if I can help it. but 2k is my absolute roof
[23:12:12] <CaptHindsight> if you ask the same questions to enough people you'll eventually get the answers you want to hear
[23:12:13] <Connor> Probably a 1HP for that machine would be good.. I would think anything bigger would be over kill
[23:12:39] <sabotender> even for aluminium alloy?
[23:12:46] <Connor> Okay, I must have been on a dead server or something.. WTF did I miss ?
[23:13:00] <Connor> sabotender: The G0704 came with a so called 1HP motor..
[23:13:00] <humble_sea_bass> Connor
[23:13:18] <humble_sea_bass> Sabo is trying to recreate the movie groundhog day
[23:13:28] <Connor> was a 650w motor.. did fine.. a little slow for alumn, but, from what you've said.. doing thin sheet, you should be fine.
[23:13:36] <humble_sea_bass> except the day restarts every ten hours
[23:13:49] <Connor> Oh. I wasn't here for the first go around.
[23:14:05] <humble_sea_bass> this is the 3rd round
[23:14:15] <Connor> I can understand... it's kinda scary spending that much $$$$ on something..
[23:14:35] <sabotender> you are a damn liar humble_sea_bass. I am asking questions so I can make a complete informed purchase
[23:14:40] <humble_sea_bass> and some ppl prefer their cucumbers pickled
[23:15:26] <CaptHindsight> it might be more of a 50 First Dates kind of thing
[23:15:31] <sabotender> go troll someone else. the only one who was spouting nonsense answers to my questions was you.
[23:15:36] <Connor> I put him on a 6040 last night because it's more sturdy than the v90.. it'll do plastic, wood, and some light metal work..
[23:15:42] <Connor> errr. aluminum
[23:16:51] <PetefromTn_Andro> Jeez it's like a sauna up in here ...
[23:17:14] <sabotender> and as I have mentioned before I know nothing about spindles and steppers and the like. So the best thing to do is ask an experienced person questions. If I am bothering you so much, why do you even respond. The smart thing to do would be silent. But instead you decide to troll me 'every 10 hours'
[23:17:18] <sabotender> anyway
[23:17:34] <sabotender> it looks like the spindle fixture is 65mm
[23:18:00] <PetefromTn_Andro> Connor did you get your three jaw bolted up yet man?
[23:18:25] <Connor> PetefromTn_Andro: I've not been out to the shop since last weekend.. Just to damn tiered after working.
[23:18:36] <Connor> I need to modify those bolts first..
[23:18:42] <Connor> and I can't even get to my drill press yet.
[23:18:58] <Connor> http://www.automationtechnologiesinc.com/products-page/cnc-spindle/800-milling-spindle
[23:19:00] <Connor> 65mm OD
[23:19:07] <PetefromTn_Andro> Jeez we're off to a bad start here man.
[23:19:23] <humble_sea_bass> speaking of VFDs I saw the most wonderful hack job at this hole in the wall dumpling restaurant in chinatown
[23:19:48] <CaptHindsight> what was it running?
[23:19:57] <Connor> sabotender: That's the proper size for the 6040
[23:20:11] <humble_sea_bass> the kitchen exaust fan for the restaurant
[23:20:20] <Connor> You'll need a VFD for it too.
[23:20:34] <humble_sea_bass> and they hooked up the VFD over one of the dining tables
[23:20:44] <sabotender> blimey, that thing weighs 8 lbs?
[23:20:49] <PetefromTn_Andro> Connor I was vibering with that fellow in NZ all afternoon he has his Cincinnati Arrow 500 at his house and he is guttering that bitch LOL.
[23:21:03] <sabotender> Connor: cool, then I will get that one
[23:21:15] <Connor> PetefromTn_Andro: Cool.
[23:21:48] <PetefromTn_Andro> Gutting damn autocomplete.
[23:21:54] <Connor> http://www.automationtechnologiesinc.com/products-page/cnc-spindle/led-display
[23:21:59] <Connor> the VFD to go with it.
[23:22:09] <Connor> Looks like they're out of stock..
[23:22:37] <humble_sea_bass> that is the chinese one that pops on ebay all the time though connor aint it
[23:22:46] <Connor> I think so.
[23:22:48] <CaptHindsight> call them to be sure, i was there last week and found boxes of things that were listed as out of stock
[23:24:13] <sabotender> tsk
[23:24:17] <Connor> sabotender: After you get the base unit in.. we can size the new steppers to it.. no sure if you'll need 1/4 or 3/8" shaft.
[23:25:07] <Connor> I would do 380-495oz in range.
[23:25:16] <Connor> no need for dual shaft.
[23:26:24] <sabotender> im not sure what dual shaft means
[23:26:34] <Connor> Shaft on both sides of motor..
[23:27:16] <Connor> Don't need it. Not using a encoder.. no point, not adding nobs or handwells, again, no point. only driving one shaft per axis.
[23:27:20] <Connor> handwheels
[23:27:46] <sabotender> would more shafts provide more stability?
[23:27:56] <Connor> huh?
[23:27:58] <Connor> No.
[23:27:58] <humble_sea_bass> no
[23:28:10] <humble_sea_bass> it just lets you manually spin it
[23:28:19] <humble_sea_bass> which you don't need to do
[23:28:26] <PetefromTn_Andro> Cya tomorrow Connor night everyone I'm falling asleep here.
[23:28:37] <Connor> PetefromTn_Andro: Okay..I'll buzz you..
[23:28:41] <Connor> no IDEA what time though.
[23:28:53] <PetefromTn_Andro> Of course not LOL.
[23:29:04] <Connor> I'll bring the shaft and bearings. :)
[23:29:26] <PetefromTn_Andro> Ooh goodie goodie hehe
[23:29:45] <PetefromTn_Andro> Cya
[23:30:06] <Connor> sabotender: You might look for a Spindle that has a ER-16 collet vs those ER11's
[23:30:13] <Connor> ER-16 is a bit more common I think..
[23:30:22] <Connor> Others can chime in on that comment.
[23:30:37] <sabotender> what is the difference?
[23:30:48] <Connor> The size of end mill they will take.
[23:31:24] <sabotender> the, um..bit?
[23:31:31] <Connor> No, End Mill
[23:31:47] <Connor> :)
[23:31:55] <sabotender> lol fine fine
[23:33:08] <Connor> er11 only good for up to 1/4"
[23:34:58] <sabotender> so i should get that digital stepper driver too eh
[23:35:10] <Connor> Which one? the MX3660 ?
[23:35:18] <sabotender> yeah
[23:35:51] <Connor> that's the one I would get.. you could use it on a different machine.. say a G0704 if you wanted to upgrade..
[23:36:01] <Connor> the g540 is a bit under rated..
[23:36:06] <Connor> and they're very close on price.
[23:36:27] <Connor> I'm not impressed with those spindles only having ER-11 collects..
[23:36:37] <Connor> might look on ebay for different sized....
[23:36:37] <sabotender> hmm not bad. 1593.79
[23:37:07] <Connor> ER11 collet -- ( for tool size 1/32", 1/16", 3/32", 1/8", 3/16",7/32", 1/4")
[23:37:08] <sabotender> i need to add in the shipping which would probably be around 150-200 for the lot
[23:37:46] <sabotender> so that spindle is no good then. hang on
[23:38:43] <Connor> Looks like that's all they're going to do.. doesn't step up to er16's till you get to larger units.
[23:39:08] <sabotender> i am afraid to get spindles from ebay
[23:39:25] <sabotender> I imagine there are endless supplies of craptastic hardware
[23:39:50] <sabotender> though, many of those spindles come with the speed controller
[23:39:56] <Connor> http://www.ebay.com/itm/NEW-800W-CNC-Router-Water-Cooled-Cooling-Spindle-Motor-1-5KW-Inverter-Drive-/121121501567?pt=LH_DefaultDomain_0&hash=item1c3367717f
[23:44:06] <sabotender> i like it
[23:44:24] <Connor> check the size..
[23:44:28] <Connor> i forgot
[23:44:49] <Connor> okay yea 65mm
[23:44:52] <sabotender> 65
[23:45:40] <sabotender> hrm. shipping is not listed; i wonder
[23:52:09] <sabotender> Connor: I was hoping to use my notebook to control this thing...for greater mobility. I want to set this up in my detached garage
[23:52:30] <Connor_iPad> Notebooks and CNC don't play.
[23:52:32] <sabotender> I am not sure how much noise this thing would make so it would be better to not have it in my flat
[23:53:41] <Connor_iPad> Need dedicated machine. A atom based computer with Hardware parallel port.
[23:53:55] <Connor_iPad> No USB to parallel. Won't work.
[23:55:19] <sabotender> huh? no this has a dual core pentium inside. what about the card slot to parallel?
[23:55:56] <Connor_iPad> Not sure. Big issue with laptops is all the power management crap.
[23:56:47] <sabotender> well. I have the latency test to run anyway. I am burning the linuxcnc disc now
[23:57:34] <Connor_iPad> Check with others in here. But everyone will say not a good idea or won't work.
[23:58:08] <sabotender> heh, if I have to, I will pull out my old PII motherboard with its AGP video card and wire that up
[23:58:44] <Connor_iPad> That might work. Probably better than laptop.
