[00:11:14] <MacGalempsy> I think it is just about there. as of now, it will only go forward. and the ENA0- still shows +5V, which needs to change to ground.
[01:30:27] <smart210> hello
[02:39:41] <Loetmichel> Mornin'
[03:03:32] <MacGalempsy> morning Loetmichel
[03:07:08] <_DJ_> moin
[03:34:55] <RyanS> TECO
[04:30:16] <MacGalempsy> morning DJ - como ca va?
[06:04:29] <hiroshima5> hi, i've get four baldor motors with microflex e100 drives what have canbus and ethernet powerlinks i/o.
[06:04:43] <hiroshima5> is there any chance to use them with emc2????
[06:05:27] <MacGalempsy> probably. it is very flexible
[06:06:16] <MacGalempsy> the best thing to do is start reading!
[06:06:56] <hiroshima5> i've been reading a lot about this
[06:07:08] <MacGalempsy> me too and I still dont get it
[06:07:21] <hiroshima5> there is one thesis project
[06:07:59] <hiroshima5> a polish university that tell they have done it
[06:08:18] <hiroshima5> http://repozytorium.umk.pl/bitstream/handle/item/426/Powerlink_CNC_2012.06.19%20-%20IEEE%20Transactions%20on%20Industrial%20Informatics%20-%20FINAL.pdf
[06:13:12] <jthornton> MacGalempsy, did you read Peter's reply to you yesterday?
[06:13:26] <MacGalempsy> yep. got the drive to move. but it will only go forward
[06:13:37] <MacGalempsy> and the EN0- still shows 5v
[06:14:04] <MacGalempsy> need to do one more report. brb
[06:14:09] <jthornton> ok
[06:17:07] <hiroshima5> MacGalempsy are you using a fpga?
[06:17:28] <MacGalempsy> mesa 5i25/7i77
[06:19:47] <hiroshima5> and do you use a powerlink connection to the drives????
[06:20:32] <MacGalempsy> nope. I got old analog equipment, except the digital spindle drive,
[06:21:17] <hiroshima5> ahh ok ok
[06:25:12] <MacGalempsy> nothing better for consulting than drilling in underbalanced scenarios, they have to drill sooooo slow
[06:25:15] <MacGalempsy> ok done
[06:28:06] <MacGalempsy> so jthornton - I was able to move the drive forward. there is a /POSenable and a /NEGenable on the card, and grounding one, or the other is supposed to feed power in that direction. what i was experiementing with is ground one, then try to move, then ground the other and try to move.
[06:29:42] <jthornton> so your drive does not use +-10v to control velocity and direction?
[06:31:02] <MacGalempsy> it should but when I try to run -power it wont go backwards
[06:32:09] <MacGalempsy> this is the amp datasheet. page 4 has a description of the /POSenable and /net enablehttp://www.copleycontrols.com/motion/pdf/4122.pdf
[06:32:19] <MacGalempsy> this is the amp datasheet. page 4 has a description of the /POSenable and /net enable http://www.copleycontrols.com/motion/pdf/4122.pdf
[06:33:50] <MacGalempsy> it says pos and neg enable inputs remain ground active for failsafe operation, but when I got to ground /pos it faults the amp
[06:34:41] <jthornton> you have a tach on the motor hooked to the drive?
[06:34:44] <Tom_itx> have you been testing just one axis?
[06:35:04] <jthornton> looking at typical connections the figure on the right is velocity
[06:35:13] <jthornton> is that how yours is conneced up?
[06:38:16] <jthornton> the pos and neg enable are used with limit switches
[06:39:14] <MacGarage> so when I jog+ it will move forward
[06:41:34] <jthornton> if pos/enable is open then it will not allow you to move in the + direction ie. if your sitting on the positive limit switch
[06:42:59] <MacGarage> actually, when I try to jog negative, it still shows positive
[06:43:08] <MacGarage> but the axis doesnt move
[06:43:23] <Tom_itx> have you tested this on more than one axis?
[06:43:24] <MacGarage> it meaning the HALMETER
[06:43:58] <jthornton> are all the enables grounded?
[06:44:25] <MacGarage> in order to power up the drive, the /posenable cannot be grounded
[06:46:15] <jthornton> that doesn't sound right
[06:46:32] <jthornton> I can see the enable needed to be open but not the limits
[06:46:41] <Tom_itx> it was why i was asking if you have tested on more than one axis
[06:47:13] <MacGarage> like just change the servo amp to another one/
[06:49:07] <jthornton> JP1 is on pins 2-3?
[06:49:21] <MacGarage> yes
[06:50:27] <jthornton> the drive should not complain if terminals 12 and 13 are grounded
[06:50:40] <Tom_itx> agreed
[06:50:46] <Tom_itx> what's the state of 14?
[06:50:52] <Tom_itx> +5 indicates fault
[06:50:55] <Tom_itx> GND is good
[06:51:03] <MacGarage> 12 requires power. if I try to ground it the drive faults
[06:51:07] <jthornton> in fact you could hard wire them grounded and use LinuxCNC to disable the drive
[06:51:39] <Tom_itx> maybe not a bad idea until you get it going at least
[06:51:43] <MacGarage> 14 reads false
[06:51:47] <jthornton> both 12 and 13 say Gnd to enable output current in
[06:51:48] <jthornton> one polarity, open or +5V to inhibit
[06:51:48] <jthornton> Typically used with grounded, nor
[06:51:48] <jthornton> mally closed limit switches.
[06:52:15] <MacGarage> false and the green light shows the drive is enabled
[06:52:55] <MacGarage> the model of control is a 800-469 and the only one that looked the same is that one I linked to
[06:53:15] <MacGarage> I think it was a custom job because 4 are on a single plate
[06:54:03] <jthornton> ok have you tried to call copley and get a manual for your drives?
[06:54:28] <MacGarage> actually now that I look closer jp is in 1-2
[06:54:41] <jthornton> hmmm
[06:54:51] <MacGarage> the board is one way and the sticker is the opposite
[06:55:43] <MacGarage> regardless, why would it go forward and not backward?
[06:55:43] <jthornton> so JP1 on pins 1-2 mean to not ground 12 and 13
[06:56:16] <jthornton> if you ground 12 or 13 it will not allow the drive to go that direction with JP1 on 1-2
[06:56:24] <MacGarage> 11 & 13 are grounded
[06:56:30] <MacGarage> 12 requires power
[06:57:24] <jthornton> by grounding 13 you are telling the drive to not move in the - direction
[06:58:20] <jthornton> 12 and 13 should have 5v to enable with JP1 on 1-2
[07:00:01] <Tom_itx> Default function with JP-1 on pins 2-3. For +5V enable and GND inhibit, move JP1 to pins 1-2
[07:00:09] <Tom_itx> seems that is backwards
[07:00:12] <Tom_itx> from what you want
[07:00:51] <jthornton> it can work either way, you just have to pick one that suits your situation
[07:00:58] <Tom_itx> agreed
[07:01:18] <Tom_itx> we typically use GND limits though
[07:01:51] <MacGarage> that is just the way it came setup
[07:02:34] <MacGarage> but, now that 12 & 13 have power the drive doesnt move
[07:03:27] <Tom_itx> sounds about right
[07:03:33] <Tom_itx> they are / active
[07:03:34] <jthornton> and 11 has 5v?
[07:04:26] <Tom_itx> also / active
[07:04:35] <jthornton> For /Inhibit function at J2-11 ( +5V enables ), move JP1 to pins 1-2
[07:04:55] <MacGarage> 11 is grounded
[07:05:14] <jthornton> that will stop the drive
[07:06:12] <MacGarage> but it still goes forward
[07:06:20] <Tom_itx> 5v on 11 will inhibit the drive according to the Connectors and PInouts chart
[07:06:48] <jthornton> if JP1 is on 2-3
[07:07:11] <MacGarage> pulling one out so i can see the jumper numbers'
[07:07:17] <Tom_itx> has he tried moving them to 2-3?
[07:08:10] <Tom_itx> that would also allow for the GND limits
[07:09:13] <MacGarage> looking at j1, the "J1" reads as a header to the pins, and they are set to the left 1-2
[07:09:34] <MacGarage> maybe I should switch this one around and see what kind of results we get
[07:09:43] <jthornton> in that position you need 5v to enable
[07:10:01] <jthornton> on 2-3 you ground to enable
[07:10:46] <Tom_itx> do those inputs require pullups in that state so no false input is read?
[07:11:53] <MacGarage> powering enable faults the drive, and it cannot be reset
[07:18:12] <MacGarage> is it possible reverse is burned up on the motor?
[07:18:47] <Tom_itx> you would have likely seen or smelled something
[07:18:51] <Tom_itx> i rather doubt it
[07:20:18] <MacGarage> halmeter axis.o.course-pos-cmd is really small
[07:21:41] <jthornton> what position is JP1 in now?
[08:59:39] * Loetmichel is milling the first few boards for the audio amp: http://www.cyrom.org/palbum/main.php?g2_itemId=14498 ... engraving bit could be sharper, but it works (selfmade out of old broken TC mill bit)
[09:09:55] <MacGalempsy> well, I had to take a break. that is driving me nuts
[09:10:25] <MacGalempsy> before the motor would move smoothly. now it moves a little and the amp faults out
[09:11:25] <MacGalempsy> if I turn down the pid number in callibration mode it wont move, if I run it up to 100 the drive will move, but then eventually fault the amp
[09:11:49] <archivist> drive not seeing feedback?
[09:12:18] <MacGalempsy> would that have to do with the tach lines?
[09:13:01] <MacGalempsy> the tach lines are plugged into the the motor leads
[09:14:52] <MacGalempsy> anyways, I called the company copely controls to ask about the proper data sheet, but had to leave a message. Hopefully the guy will call back later.
[09:17:52] <MacGalempsy> im going to bed. thanks again everyone. thinking about starting to try the same thing on the y axis and see if something else happens. ciao
[09:18:37] <archivist> the tach lines plugged into motor leads sound very wrong
[09:19:19] <archivist> or are you stating it incorrectly
[09:19:43] <MacGalempsy> the manual said to connect the leads to the positive and negative terminals
[09:19:48] <MacGalempsy> of the motor
[09:20:06] <archivist> the tach lines come from the motor and go to the amp as far as I know
[09:20:08] <jdh> that woudl be interesting
[09:20:20] <MacGalempsy> so I connected them to the power to motor lines
[09:20:31] <jdh> the tach lines come from the tach, which might be attached to the motor
[09:20:33] <archivist> the amp out drives the motor NOT the tach
[09:21:16] <ju-emb> magic smoke is still inside the tach?
[09:21:18] <archivist> fat wires power, thin wires tach
[09:22:11] <MacGalempsy> there is no tach leads coming from the motor
[09:22:37] <archivist> motor... how many wires
[09:22:45] <MacGalempsy> they were connected to the old mainboard
[09:24:36] <archivist> tach is an input on the amp,
[09:26:26] <MacGarage> ok i disconnected that and it moves smoothly in the pos dir onlyh
[09:28:36] <MacGarage> how do I tell if linux cnc is sending it negative voltage?
[09:28:48] <archivist> meter/scope
[09:29:01] <MacGarage> I have the meter out but not sure of the exact pin
[09:29:13] <archivist> and is negative even possible
[09:29:33] <MacGarage> some how the polarity has to switch to reverse the motor, no?
[09:30:06] <archivist> depends where the zero point is,
[09:30:49] <MacGarage> zero point?
[09:31:07] <archivist> what voltage means stationary
[09:32:18] <pcw_home> You will need the tach wired to the drive for any reasonable behaviour
[09:33:13] <archivist> does he have a tach
[09:33:16] <MacGarage> the tach are leads coming from the drive that were wired to the old controller board
[09:33:38] <pcw_home> Do the motors have Tachometers?
[09:34:05] <MacGarage> only 2 wires coming from the motors
[09:34:45] <pcw_home> only encoders on the back of motors?
[09:34:46] <MacGarage> the datasheet said to connect the tach lines to the positive and negative terminals of the motors
[09:35:10] <MacGarage> encoders are attached to the pulleys
[09:36:08] <MacGarage> perhaps I need to tune the PID first?
[09:36:10] <pcw_home> tach input to motor leads sounds wrong
[09:36:31] <MacGarage> i disconnected the tach to motor leads and the faulting stopped
[09:37:01] <MacGarage> when I first thought about the tach, I thought it was just for output
[09:37:39] <pcw_home> no point in messing with linuxcnc unless you can drive the motors back and forth with a small voltage (say 1.5V battery)
[09:40:57] <pcw_home> Without tachometer feedback you are either going to have to run the motor in torque mode
[09:40:59] <pcw_home> (which will involve changing the settings on the drive) or use spare 7I77 analog outputs to
[09:41:00] <pcw_home> simulate the tachometer (assuming +-10V is enough voltage for the tach input)
[09:41:08] <MacGalempsy> is there a way to send the appropriate signal to the tachs with linuxcnc?
[09:41:27] <MacGalempsy> ok
[09:42:03] <MacGalempsy> will start reading up how to do that
[09:42:28] <pcw_home> Do you have a drive manual?
[09:42:50] <MacGalempsy> the closest one I can find is http://www.copleycontrols.com/motion/pdf/4122.pdf
[09:43:39] <MacGalempsy> physically the drives are the same, but on this one, /POSenable will fault the drive if it is grounded
[09:44:05] <MacGalempsy> so if I leave it open or powered then the drive enables
[09:46:52] <MacGalempsy> if I was running in torque mode, would anything need to change?
[09:47:58] <MacGalempsy> the digital drive has a toggle to torque mode, i noticed that in the the settings
[09:48:27] <pcw_home> Depending on how its done, you would have to change jumpers or components
[09:49:04] <MacGalempsy> i am wondering if the machine is supposed to be run in torque mode. how would I tell?
[09:49:36] <MacGalempsy> the manual shows the way it is wired here in torque mode because there is no tach
[09:50:05] <pcw_home> If it had anything connectd to the Tach input, its probably in velocity mode
[09:50:13] <pcw_home> connected
[09:50:46] <MacGalempsy> would there be any benifit to going to torque mode?
[09:52:49] <pcw_home> torque mode: harder to tune, needs higher servo thread rate, but allows torque monitoring/limiting
[09:53:49] <pcw_home> velocity mode: easier to tune, low thread rate (with tach, high thread rate still needed with simulated tach)
[09:54:57] <pcw_home> torque mode will likel require you to change at least one component on the drive (if it like the drive in manual you linked to)
[09:55:03] <pcw_home> likely
[09:56:13] <MacGalempsy> ok. so simulating the tach signal will be the best because it requires just programming
[09:58:28] <MacGalempsy> i see a thread here
[09:59:40] <hiroshima5> has anybody used drivers with powerlink connection?
[10:02:40] <archivist> hmm claims to be open... but is it ? http://www.estun.com/en/product/ac-servo-system-motion-control-system/digital-field-bus/powerlink.html
[10:08:30] <hiroshima5> yes
[10:08:58] <hiroshima5> i've only discovered this project
[10:08:59] <hiroshima5> http://repozytorium.umk.pl/bitstream/handle/item/426/Powerlink_CNC_2012.06.19%20-%20IEEE%20Transactions%20on%20Industrial%20Informatics%20-%20FINAL.pdf
[10:09:16] <hiroshima5> but nothing easy to install
[10:09:37] <hiroshima5> i have 4 baldor microflex e100
[10:09:49] <hiroshima5> and i don't know how use them with emc2
[10:10:08] <archivist> the source appears to be bsd http://sourceforge.net/projects/openpowerlink/
[10:13:45] <hiroshima5> i'm so confused with it
[10:14:01] <hiroshima5> i've no idea how i can get it working...
[10:15:26] <hiroshima5> http://www.baldormotion.com/products/servodrives/microflex_e100.asp
[11:13:19] <ju-emb> hiroshima5: reading the manual of your baldor microflex tells me, that, for complex and flexible movements, you need an additional motioncontroller. In fact that's an additional hardware.
[11:14:27] <archivist> but linuxcnc is a motion controller
[11:15:27] <ju-emb> I havn't read the CAN part right now, but what I know about CAN enabled servo drives, there is a possibility to let them move with linuxcnc, whenever a aditional (maybe homemade) software is necessary.
[11:16:24] <ju-emb> archivist: sure it is, but baldor talks about baldor motion-controller not opensource motion controller
[11:16:33] <archivist> he is looking at ethernet not can bus
[11:17:11] <archivist> I have not read any of the baldor docs
[11:17:47] <ju-emb> baldor doesn't tell anything about how you control the drive over ethernet, that's all in their software
[11:19:29] <ju-emb> CAN on some Servo drives i know, has PDO's that can be used to make the drive behave like a Step Dir controller
[11:20:17] <ju-emb> I need to have a look at the software to tell what's possible with that drives
[11:24:13] <hiroshima5> not problem for me if i can use the can port
[11:25:27] <hiroshima5> i only want to get them moving
[11:41:10] <jdh> we have some parker powerlink drives
[11:42:21] <ju-emb> that's a joke, the Baldor manual describes the entire Object Hierarchy, but not to what drive functions the objects are mapped
[11:43:05] <ju-emb> so the CAN on that drive is pretty much the same mystery like the Ethernet
[11:43:55] <jdh> isn't that true of most CAN devices?
[11:44:08] <jdh> CAN is 'open', but the implementation is not.
[11:48:28] <archivist> open one up and read the roms :)
[11:51:02] <ju-emb> archivist: and feed that reading into your crystal sphere ;-o
[11:51:32] <archivist> reverse engineering to interoperate is legal in some countries
[11:52:16] <archivist> can be hard work
[11:53:26] <ju-emb> but works out only in countries with cheap labour
[11:53:58] <archivist> I used to get payed to do it :)
[11:54:27] <ju-emb> today it's cheaper developing your own servodrive
[11:59:19] <IchGuckLive> hi all B)
[11:59:37] <PetefromTn> Hey Ich.....Damn I burnt my Grilled ham and cheese sammich.
[12:00:12] <IchGuckLive> as black as it is it may taste good
[12:00:29] <PetefromTn> meh.....not terrible.
[12:00:34] <ju-emb> PetefromTn: next time use classicladder to control it
[12:01:06] <PetefromTn> ju-emb: Damn good idea man...I just need to figure out how to build a classic Ladder because I need it on my VMC's toolchanger LOL
[12:01:07] <IchGuckLive> new nick ju-emb welcome
[12:01:08] <CaptHindsight> PetefromTn: are you going to eat that sammich in your frunchroom?
[12:01:24] <PetefromTn> whazza Frunchroom?
[12:01:40] <IchGuckLive> french
[12:01:46] <CaptHindsight> front room
[12:02:10] <ju-emb> IchGuckLive: thanks
[12:02:27] <IchGuckLive> where are you from in the world
[12:02:54] <PetefromTn> Yeah how did you know? I just came in from the woodshop and made lunch. Got almost all the furniture grade plywood cut up into parts now I gotta drill all the damn shelf pin holes etc..
[12:03:01] <ju-emb> native germany, but living and working in Peru at current
[12:03:16] <CaptHindsight> Chikago english also includes sammich for sandwich and funchroom for front/living room
[12:03:19] <IchGuckLive> ich sitz in Kaiserslautern
[12:03:35] <PetefromTn> Never ceases to amaze me the wide array of people we have here from all around the world.
[12:03:46] <PetefromTn> CaptHindsight: Oh really did not know that thanks...
[12:03:53] <hiroshima5> so i understand that it's near impossible or at least so much difficult to use those baldor drives with something different than nextmotion e100 and baldor software?
[12:03:56] <IchGuckLive> PetefromTn: did you get some cabinet images online yesterday
[12:03:59] <PetefromTn> I just always called a sandwich a Sammich to be funny.
[12:04:04] <ju-emb> Du bist ziehmlich aktiv hier
[12:04:35] <PetefromTn> IchGuckLive: LOL I was working on it for ya but then you had to logoff
[12:04:35] <IchGuckLive> ju-emb: ich hab auch 150maschinen im einsatz
[12:04:48] <IchGuckLive> PetefromTn: as always
[12:05:34] <IchGuckLive> ju-emb: what cnc work is done in peru
[12:06:06] <ju-emb> CNC is a really amazing field here
[12:06:17] <ju-emb> retrofit mostly
[12:06:45] <IchGuckLive> hiroshima5: is it a M nN or D drive
[12:06:59] <ju-emb> old machines are imported here from all over the world, but mainly with none working electronics
[12:07:34] <IchGuckLive> ju-emb: then you are right here look into mesa stuff and your mashine will run
[12:08:02] <ju-emb> I have alrady machines running with mesa stuff
[12:08:11] <IchGuckLive> SMILES
[12:08:38] <hiroshima5> the motors are bsm63n-175af
[12:08:53] <IchGuckLive> and the drives Flex ?
[12:09:20] <hiroshima5> and the drive is microflex e100
[12:10:48] <IchGuckLive> hiroshima5: this is 4000 RPM stuff quit hevy and unusiual
[12:11:17] <hiroshima5> i'm building a plasma cutter table for my final master project
[12:11:35] <IchGuckLive> with SERVOS
[12:11:37] <hiroshima5> and the proffesor gave me those motors due to he has them unused
[12:11:52] <IchGuckLive> i got 5 plasmas running on ordanary Steppers at 0,1mm
[12:12:07] <IchGuckLive> at max 5m/min cutt rate to a 4mm plate
[12:12:12] <ju-emb> the prof knows why he gave it to you ;-)
[12:12:29] <IchGuckLive> ju-emb: i agree
[12:12:45] <hiroshima5> i'm not pretty sure he knows it
[12:12:46] <hiroshima5> hehehehe
[12:13:09] <IchGuckLive> hiroshima5: you can get it all for less then one drive cost
[12:13:09] <hiroshima5> he want to spend the minimum money at possible
[12:13:38] <hiroshima5> i would say him than we have to use different motors
[12:13:55] <hiroshima5> but at least i would want to know if we could use them
[12:14:07] <PetefromTn> http://imagebin.org/277026
[12:14:13] <PetefromTn> http://imagebin.org/index.php?mode=image&id=277027
[12:14:59] <PetefromTn> This is the last built in I finished. Nothing fancy but it did have an 11' long solid oak butcherblock countertop. There is Audio visual stuff in the lower cabinets.
[12:15:27] <PetefromTn> If you right click on them and hit view image you get the better picture at least on my screen LOL.
[12:15:29] <ju-emb> PetefromTn: congrats, looks really pretty
[12:15:31] <jdh> Pete: all by hand, or big cnc router?
[12:15:32] <hiroshima5> the fact is those motors were in boxes on shelfs. Totally unused
[12:15:41] <IchGuckLive> hiroshima5: http://s.taobao.com/search?initiative_id=staobaoz_20131115&jc=1&q=M880a&stats_click=search_radio_all%3A1
[12:16:02] <PetefromTn> jdh: No cnc here man I wish, I only have one CNC and that is the CIncinatti Arrow 500 VMC
[12:16:16] <IchGuckLive> this will sent you to the hevens universe CNC door
[12:16:18] <PetefromTn> ju-emb: Thanks man..
[12:16:42] <jdh> Pete: seems like a 4x8' router would do wonders for you.
[12:16:49] <ju-emb> hiroshima5: you can use that motors and drives to make your parking lot boom open and close
[12:17:00] <IchGuckLive> hir the M880a is 580Yen
[12:18:03] <PetefromTn> jdh Yeah I agree, I actually considered selling the VMC to get a nice CNC flatbed router with vacuum table but now I am actually getting some interest in CNC machine work too so I am doing the woodworking in the shop the old fashioned way on the tablesaw and shaper etc and then do the metalworking in the evening
[12:18:14] <IchGuckLive> and a sandard BOB with a Atom D525 http://s.taobao.com/search?initiative_id=staobaoz_20131115&jc=1&q=MW525&stats_click=search_radio_all%3A1 at 420 Yen
[12:18:45] <PetefromTn> I need to find the high end kitchen pictures I did you guys would love them I think... This was a simple built in with inset doors.
[12:18:50] <jdh> Pete: surely you could just make an extrusion based router table fairly cheap (few thousand $$)
[12:19:38] <PetefromTn> Oh yeah I could but I also have a room issue. With the VMC in there and the rest of my equipment It would be difficult to work if there was also a flatbed router large enough to process sheet goods.
[12:19:42] <CaptHindsight> http://www.kickstarter.com/projects/1638882643/diwire-the-first-desktop-wire-bender I didn't realize that a $3K cnc wire bender would be so popular
[12:19:52] <hiroshima5> thank you ichgucklive jdh ju-emb...
[12:20:07] <IchGuckLive> hiroshima5: Thats why we are here
[12:20:22] <hiroshima5> i will tell him that we cannot use those motors!!
[12:22:39] <ju-emb> sure they have some use, but not for the plasma cutter ;-)
[12:23:25] <IchGuckLive> hiroshima5: http://item.taobao.com/item.htm?spm=a230r.1.14.27.mgLSJY&id=14601070022
[12:23:39] <IchGuckLive> all in one for 1250Yen
[12:24:02] <ju-emb> IchGuckLive: do you have some of that 7i43 in use?
[12:24:02] <IchGuckLive> But its the lower end of the game
[12:24:13] <IchGuckLive> i use 7176
[12:25:15] <hiroshima5> i've not told you that the table is 2,4x1,2m
[12:25:21] <hiroshima5> steel made
[12:25:37] <IchGuckLive> myne is 2,8 on 1,8m
[12:26:14] <IchGuckLive> http://www.youtube.com/watch?v=V6kllGspehQ Thats my channel
[12:26:21] <IchGuckLive> see the cad
[12:27:14] <IchGuckLive> hiroshima5: tiing belt i guess
[12:27:22] <IchGuckLive> timing Belt
[12:28:51] <hiroshima5> rack
[12:29:00] <IchGuckLive> thats the best
[12:29:34] <IchGuckLive> i use it 2 with a 30:1 gear for wood 0,01
[12:29:55] <IchGuckLive> and 3:1 for plasma
[12:30:47] <ju-emb> IchGuckLive: what cutting speed do you get on that cutter with the step motors?
[12:31:08] <ju-emb> thin sheet cutting
[12:31:17] <IchGuckLive> with 0,2mm per step 15m/min
[12:31:35] <IchGuckLive> the plasma only makes 5500mm/min max
[12:32:06] <IchGuckLive> at 8Nm steppers on the gear rack and pinion system
[12:37:31] <ju-emb> that's the PCB drill I made for our in house use
[12:37:33] <ju-emb> http://www.youtube.com/watch?v=qRk6YatSRHQ
[12:40:26] <IchGuckLive> quite professionell
[12:41:29] <ju-emb> and the video it's true speed, not faked
[12:42:06] <ju-emb> 4mm pitch on X Y 2mm on Z
[12:42:38] <IchGuckLive> with steppers ? it goes smooth
[12:43:47] <ju-emb> yes, all steppers, works on a 5i23 home made Stepper driver
[13:12:36] <IchGuckLive> FOR all in Europ there is a Homemade CNC 3D printing Studie today on ASTRA sat Dish STATION 3Sat 20:15 MEZ
[13:13:38] <IchGuckLive> How 3D prionting and homemade Routes may change the World of design
[13:17:41] <IchGuckLive> ok im off bye !
[13:32:18] <gonzo_> had a discussion with the lads at work, as they were raving about how 3d printing was going to change the world.
[13:33:01] <gonzo_> I mentioned a better technique that was still very secret, where you take a block of plastic/metal etc and cut away the bits you don't want
[13:33:19] <gonzo_> they were impressed and went off to google it
[13:35:39] <skunkworks> http://www.youtube.com/watch?v=M7FIvfx5J10
[14:24:04] <PetefromTn> That hurt me just watching it LOL.
[14:29:31] <FinboySlick> They cheated a little... The truck splitting isn't the semi, the semi is going perfectly straight.
[14:30:18] <FinboySlick> From a related video, the original plan was to use two semi.
[16:25:22] <ctordtor> If I have a 3 axis milling machine, which direction should the table move when I press the left arrow key?
[16:29:59] <mrsun_> left? :P
[16:30:52] <ctordtor> ha, sorry if that's a weird question, I was experimenting and wanted to make sure it's going the correct way
[16:31:12] <mrsun_> well its the most logical
[16:31:33] <mrsun_> X- == left, X+ == right
[16:31:33] <mrsun_> imo
[16:32:32] <ctordtor> I think I confused myself by trying to think about the end mill looking down on the table
[16:33:15] <mrsun_> better to look how your cam software views the "table"
[16:33:38] <mrsun_> where X- is left, X+ is right, Y- is down (towards you) Y+ is up (away from you)
[16:34:54] <ctordtor> makes more sense
[17:06:10] <_DJ_> gn8
[17:18:32] <MacGalempsy> well just got off the phone with the guy at copely controls. they made a special order but he thingk the drive is messed up
[17:22:25] <Tom_itx> uh oh
[17:22:35] <Tom_itx> all of em?
[17:23:40] <MacGalempsy> that is what I was saying
[17:24:08] <MacGalempsy> but he couldnt see anything in the schematic that they did when sending the unit to the client
[17:24:10] <Tom_itx> was it used or new?
[17:24:46] <MacGalempsy> so I was thinking the missing velocity informaiton had something to do with it
[17:24:57] <MacGalempsy> machine retrofit, used
[17:27:48] <Tom_itx> make any offers to fix it?
[17:28:36] <MacGalempsy> he mentioned they dont work on those particular units anymore, but there is a replacement unit that will work
[17:33:43] <JT_Shop> I'd try all three before tossing in the towel
[17:36:14] <Tom_itx> yeah
[17:44:54] <JT_Shop> darn it got too dark to split wood
[17:45:46] <Jymmm> JT_Shop: http://www.amazon.com/dp/B004XN5MBW/ref=wl_it_dp_o_pd_S_ttl?_encoding=UTF8&colid=3QOFKF7BT7TE7&coliid=IT5TW9IQ6UKQ2
[17:46:27] <Jymmm> JT_Shop: It's the best overall headlamp I've found in three years of looking/tryning many different kinds.
[17:47:23] <Jymmm> JT_Shop: Take ONE AA (not 3 or 4 AAA's), IPX8 rated, Good beam/flood, long life per set of battery.
[17:48:06] <Jymmm> JT_Shop: Flip up the diffuser for bicycling, flip down for working under the hood, on the bbq, etc.
[17:48:53] <MacGalempsy> that is a pretty good beam coming off . how many watt is that led?
[17:49:04] <Jymmm> JT_Shop: I always thought headlamps were dorky, till I was on a ladder installing a gang box and needed three hands.
[17:49:20] <Jymmm> MacGalempsy: 90 Lumen
[17:49:34] <Jymmm> to 3 lumen
[17:49:51] <Jymmm> 50 hours at 3 lumen for one AA battery.
[17:51:11] <Jymmm> It's the ONLY ipx* rated headlamp I've seen that takes AA
[17:51:15] <Jymmm> ipx8
[17:51:22] <Tom_itx> jerks, $34.95 ... free shipping on orders over 35
[17:51:43] <MacGalempsy> lol. just order the battery that goes with it
[17:51:48] <Jymmm> Yeah, blame amazon for that crap.
[17:52:06] <Tom_itx> i bet that triggers no matter the cost of the item
[17:52:34] <MacGalempsy> well, it is on sale, so hopefully the shipping isnt more than the differnce you saved
[17:54:37] <JT_Shop> can you pivot the light up and down, that is somewhat important on a mountain bike
[17:54:52] <Tom_itx> JT_Shop did you finish your splitter?
[17:54:56] <Tom_itx> never did see the end product
[17:55:12] <JT_Shop> not yet, work has been slowing down that project
[17:55:22] <Tom_itx> that's a good thing
[17:58:09] <JT_Shop> I need to fab up the hyd tank and plumb the thing then spill some paint on it
[17:58:24] <Jymmm> Is there a paint/coating I can spray on SS,submerge in salt water and it will stay, but will come off with soap or some other simple method?
[17:59:21] <Jymmm> I want to try this http://www.instructables.com/id/Negative-Laser-Metal-Etching/
[17:59:22] <Tom_itx> wax
[17:59:24] <MacGalempsy> unfortunately, NaSO4 and NaCl in solution are very similar affinities
[17:59:48] <MacGalempsy> yes, wax is a good one
[17:59:54] <Jymmm> Tom_itx: Dont think I can laser wax easily
[18:00:10] <Tom_itx> now you're just adding more criteria to the equasion
[18:00:17] <Tom_itx> you asked for a coating
[18:00:37] * Jymmm hugs Tom_itx
[18:01:13] <Tom_itx> dykem comes off reasonably well
[18:01:20] <Jymmm> Actually, I never tried lasering wax... Maybe I can just vaporize it.
[18:01:53] <Tom_itx> may melt around the cut somewhat
[18:02:05] <Jymmm> Eh, I cna adjust for that.
[18:02:25] <Tom_itx> vaporize it or set your house on fire
[18:02:46] <Jymmm> Tom_itx: Heh, why do you think I have a nitrogen tank for =)
[18:04:11] <Jymmm> just flood the compartment... no more flames!
[18:04:50] <Jymmm> How about something that comes off with heat (other than wax)?
[18:05:16] <Tom_itx> not sure
[18:05:45] <Jymmm> does this stuff go on thin? http://www.grainger.com/product/DYKEM-Blue-Layout-Fluid-2C945
[18:05:55] <Tom_itx> the spray does
[18:05:59] <Tom_itx> didn't click
[18:06:12] <Jymmm> ah, ok
[18:06:19] <Jymmm> Ah, remover... http://www.grainger.com/product/SPRAYON-Layout-Fluid-Remover-1D271?opr=OAPD&pbi=2C945
[18:06:41] <Tom_itx> probably laquer or enamel thinner would do it
[18:07:04] <Tom_itx> maybe even iso
[18:07:06] <Tom_itx> i dunno
[18:07:06] <Jymmm> TOLUENE and ACETONE
[18:07:15] <Jymmm> just read the MSDS
[18:07:50] <Jymmm> Now just to find SS shim stock CHEAP
[18:09:45] <Tom_itx> what thickness?
[18:09:56] <Jymmm> 0.010"
[18:10:40] <Jymmm> 302/304 Full Hard
[18:10:56] <Tom_itx> more specs....
[18:10:58] <Jymmm> 4" wide would be ideal,
[18:10:58] <Tom_itx> i swear
[18:11:19] <Tom_itx> you could cut that with a paper shear maybe
[18:11:20] <Jymmm> You want the composition? lol
[18:11:52] <Jymmm> It's close

[18:16:29] <Tom_itx> dog tags?
[18:16:50] <Jymmm> you need some?
[18:16:53] <Tom_itx> no
[18:17:07] <Jymmm> Those I can get if you do
[18:17:09] <Tom_itx> also ask the dudes that make ss stencils for solder mask
[18:17:20] <Tom_itx> where they get theirs
[18:17:40] <Jymmm> They use MUCH thinner than 0.01
[18:17:52] <Tom_itx> same suppliers though
[18:18:04] <Tom_itx> probably .003 or so
[18:18:15] <Tom_itx> maybe a bit thicker
[18:18:45] <Jymmm> god idea
[18:18:55] <Jymmm> good*
[18:19:04] <Jymmm> bbiab
[18:54:19] <MacGalempsy> /away
[18:54:34] <MacGalempsy> \away
[18:54:38] <MacGalempsy> hah oops
[21:01:08] <eric_unterhausen> is there an XZC config in samples?. I guess I want a lathe config, but I have complete control over the C spindle and also have a spindle mounted on Z
[21:02:15] <eric_unterhausen> if I do G01 Xxx Cyy F10, does that mean that C rotates at 10 deg/min and X moves at 10mm/min?
[21:04:20] <skunkworks> If I understand it - x moves at 10ipm if it can - (if C can go fast enough to do it..) so they both end at the same time
[21:04:55] <skunkworks> if it was just C then it would be in deg/min
[21:04:59] <skunkworks> F
[23:22:06] <ju-emb> some advice how to run glade with hal components on a sim machine?
[23:23:41] <ju-emb> oops, wrong tab
