[00:49:45] <emperordane> anyone toyed with scarakins recently?
[01:01:12] <MattyMatt2> jts .glade is common to all glade files for all gtk progs, so I'm guessing .ui is just a way of signifying it's a vcp file
[01:01:34] <emperordane> eh?
[01:03:20] <psha> MattyMatt2: he's disconnected :(
[01:03:31] <MattyMatt2> oh yeah
[01:03:50] <psha> regarding glade/ui - they are used to distinguish libglade and gtkbuilder formats
[01:03:57] <psha> but really it may be even .docx
[01:04:08] <psha> format is important, extension - not
[01:05:06] <MattyMatt2> ah OK
[01:06:52] <MattyMatt2> I'm here to ask if there's any concern that G4 P- is in seconds in emc2 but in milliseconds in RS-274D, is there any desire to change that?
[01:07:56] <MattyMatt2> it's a moot question, as any CAM prog I use will need to have the option to select anyway
[01:09:52] <psha> i guess it will break every program already using this parameter
[01:10:29] <psha> so only way to do is via config file variable that controls second/ms mode

[02:07:43] <memleak> Hi. I messed up my google code page by mistake for the ArchLinux EMC page. The wiki now links to a dead link but is read-only.
[02:08:09] <memleak> I erased every wiki I had and they are now unrecoverable. i hate google code now...
[02:12:34] <memleak> I just wanted to let you know so somebody can clean up the EMC wiki and remove the dead link. I apologize for this mess..
[02:33:48] <raynerd> anyone on here use v-carve?
[02:34:51] <raynerd> stupid one as usual from me...but... I`ve made the drawing in vcarve, calculated and previewed the cutting pattern and can`t see how to actually take the g-code and import to emc2
[02:53:08] <cncbasher> MattyMatt2: as i understand G4 dwell can be either milliseconds or seconds
[02:59:00] <cncbasher> raynerd: once all the paths are completed for milling , you select the layer to produce the gcode
[03:00:04] <cncbasher> until the steps are completed , it will not allow gcode to be outputted
[03:01:16] <cncbasher> i'l just start mine up 1 min
[03:04:16] <cncbasher> go to save toolpath , and you should then be able to select the post processor
[03:04:51] <cncbasher> tick the box for the gcode path you wish
[03:05:00] <cncbasher> in the toolpath list
[03:06:10] <cncbasher> then at the bottom click the save toolpaths(s) button
[03:06:21] <cncbasher> and you should then have your gcode
[03:15:50] <mazafaka> going to buy some 14-megapixels camera...
[03:27:52] <Valen> 's a lot of mpix
[03:28:00] <Valen> got the glass for it?
[04:01:34] <MattyMatt2> there's a phone coming out with 41Mpix
[04:02:20] <MattyMatt2> fixed Zeiss lens and extreme software zooming
[04:04:31] <MattyMatt2> http://news.bbc.co.uk/1/hi/programmes/click_online/9701829.stm 3:39
[04:07:39] <archivist> not real 41mpx
[04:13:13] <MattyMatt2> a cmos sensor used to be a dram chip with a glass window, so afaics they should match current dram sizes
[04:14:11] <MattyMatt2> I ground the top off a dram chip once to try and make one :) I overdid it right at the end and chipped the chip
[04:14:43] <MattyMatt2> 64k x 1
[04:16:37] <MattyMatt2> I could try that again now I have a cnc dremel pusher
[04:17:01] <MattyMatt2> and a bunch of dip rams
[05:07:40] <mazafaka> Valen: Samsung WB700 + 16 GB flash disk
[05:52:59] <Mjolinor> got my PCB mill running smoothly adn can go from schematic through PCB to gcode all easily
[05:53:55] <Mjolinor> I was thinking about things like name plaques or other items that dont need a lot of Z axis and could do with some imput on which way to do it, there are lots of offerings like freecad andqcad etcetc but which is easiest to learn and has hte funcitonality to do 3d
[05:55:10] <Mjolinor> freecad seems to be a dog but I htink it ismainly because you can't get started to learn it, the tutorial doesn't do what it say sit will when you try to follow it and wihtout at least abasic get you started tutorial you can't learn cad programmes as they are not intuitive they jsut have arbitary ways fo doing things that you ahve to be told
[05:55:43] <Thetawaves> you are right
[05:56:07] <Thetawaves> people here have told me that freecad can be usable once you learn
[05:56:16] <Mjolinor> it seems so
[05:56:32] <Mjolinor> I tried the irc freecad room but got nothign sensible and hte turorial jsut sucks
[05:56:53] <Thetawaves> i was told to watch the freecad videos on youtube
[05:57:17] <Mjolinor> hmm, good idea, I tend not to use you tube because I dont have any speakers :)
[05:57:30] <Mjolinor> ill stick soem on and go lookin gon there
[05:58:03] <Thetawaves> you will need speakers for youtube
[05:58:49] <Mjolinor> its hard to believe that so much effort has gone into freecad and so liittle into the most basic tutorial
[05:58:55] <Mjolinor> http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Basic_modeling_tutorial
[05:59:11] <Mjolinor> I tried following that but instead of getting a solid extrusion I get a thin shell extrusion
[05:59:45] <Mjolinor> no reasons why, no idea how to sotp it , tried removing it and all its configs and reinstalling and I am still stuck with a can rather than a solid when I extrude a circle
[06:00:11] <Mjolinor> so obviously soem defaults soemwhere are wrong but no explanation anywhere as to what
[06:01:03] <Mjolinor> on the right, a "None" button. Click it, and on the left will appear right after "active command": Select Plane Offset, then a text field and a series of buttons.
[06:01:31] <Mjolinor> it tells me to do that but I do not have "active command" writeen anywehre on the screen and so cant select plane offset
[06:01:49] <Mjolinor> its a really simple one page tutorial to get you started adn it jsut fails in so many places
[06:01:53] <Mjolinor> pity really
[06:03:22] <Thetawaves> how old is it?
[06:03:30] <Mjolinor> what?
[06:03:33] <Mjolinor> my version?
[06:03:43] <Mjolinor> its off the current ubuntu feeds, 0.10 I think
[06:03:55] <Thetawaves> no the tutorial
[06:04:22] <Mjolinor> no idea
[06:05:29] <Thetawaves> PathGenerators/PushCutter.py:130 needs to be changed to distance = pnorm(psub(p2, p1))
[06:06:10] <Thetawaves> also need to import the PointUtils module functions
[06:10:01] <Thetawaves> oops
[06:10:04] <Thetawaves> wrong damn channel
[06:10:16] <Mjolinor> I was only slightly confused
[08:29:41] <anonimas1> anyone knows fanuc 10t?
[08:33:54] <Tom_itx> anonimas1, what did you need to know?
[08:34:24] <anonimas1> everything
[08:34:27] <pfred1> Tom_itx everything! So begin at the beginning.
[08:34:38] <pfred1> see?
[08:34:41] <anonimas1> I am trynig to run my lathe i've loaded a program into it
[08:34:54] <Tom_itx> i just have a pocket reference i kept from one of the okumas
[08:35:10] <anonimas1> however it stops on every line liting the single block button
[08:35:15] <Tom_itx> i was thinking they were fanuc
[08:35:28] <anonimas1> requiring me to press reset and the start button again to get it to the next line
[08:36:02] <Tom_itx> unfortunately it's gonna be a while before i can locate that book. i'm moving my office today
[08:36:43] <pfred1> I hate moving I might as well just invest in some gasoline and a match
[08:36:52] <Tom_itx> it was a pocket reference for an okuma lathe which like i said i think is fanuc
[08:36:55] <anonimas1> is it supposed to do it like that?
[08:36:58] <pfred1> end result is the same
[08:37:12] <anonimas1> (it seems strange) maybe i have some setting error somewhere
[08:37:13] <Tom_itx> anonimas1, not really
[08:38:24] <anonimas1> my gf is rushing to make more parts on the mill(she is making them not me) :) got to run.
[08:38:40] <anonimas1> think about if you can remember something about it i'll be on and off
[08:39:42] <Tom_itx> anonimas1, ok. gimme some time to dig and find the book
[08:40:03] <pfred1> Tom_itx why are you moving your office?
[08:43:37] <Tom_itx> from one room to the other
[08:43:41] <Tom_itx> in the house
[08:44:01] <pfred1> any particular reason?
[08:44:21] <Tom_itx> more room?
[08:44:29] <pfred1> that'd be a reason
[08:44:44] <pfred1> you're expanding
[09:04:16] <mazafaka> http://www.youtube.com/watch?v=FyL0wufU_2w&context=C3307ee4ADOEgsToPDskLXh8zWbknMxpyOxUlAaKM5
[09:05:00] <pfred1> where are the pedals?
[09:07:36] <mazafaka> they're in the stock
[09:40:37] <mazafaka> jthornton:
http://www.flickr.com/photos/ilyagalkin/6806116324/in/photostream
[09:42:42] <pfred1> is that plastic sheeting behind the wood stove?
[09:42:51] <mazafaka> Well, decided to leave the wood stove as is. It heats up the garage very, very quickly.
[09:43:36] <pfred1> looks to be polyethylene sheet to me
[09:43:46] <mazafaka> no, it's aluminum and it's cold and does not heat up the cellophane garment
[09:43:59] <pfred1> which is basically gasoline rolled out
[09:44:25] <mazafaka> yes, there's snow on the doors while it's +20 celsius in the garage (and -10 down to -40 celsius at the street)
[09:45:00] <mazafaka> pfred1: garage has gasoline and distillers, and a ballon of oxigen
[09:45:25] <mazafaka> all withing 3.6x5.6.2 = X square meters
[09:45:39] <mazafaka> not square meters
[09:48:10] <pfred1> mazafaka
http://i.imgur.com/ee0zi.jpg
[09:50:14] <mazafaka> "This here" is a plastic which borders hot inner space from cold doors
[09:50:30] <pfred1> I wish I had batteries for my camera I keep on forgetting to pick new ones up
[09:50:45] <pfred1> yeah i thought that was plastic
[09:50:45] <mazafaka> pfred1: Whole garage is this-tiny:
http://www.flickr.com/photos/ilyagalkin/6952243523/sizes/l/in/photostream/
[09:51:27] <pfred1> nice shelves
[09:51:47] <pfred1> whats with all the orange crates?
[09:52:09] <mazafaka> orange crates? What do you mean?
[09:52:22] <pfred1> those wood slat boxes aren't orange crates?
[09:53:01] <mazafaka> spannes and files, and a box of scrap metal used for welding
[09:53:13] <mazafaka> *spanners
[09:53:36] <pfred1> looks like one under your back bench has seen better days
[09:54:43] <pfred1> mazafaka I like woodworking so I make my own wooden boxes
http://i.imgur.com/VannV.jpg
[09:55:38] <pfred1> I just got done making a retaining flange for a circular saw I picked up at a flea market last week
[09:55:56] <pfred1> when i bought it I didn't realize it was missing
[09:56:08] <pfred1> the sly dog sold it to me without a blade mounted
[09:56:29] <mazafaka> pfred1: What do you mean. This bike with fenders (at right at
http://www.flickr.com/photos/ilyagalkin/6952243523/sizes/l/in/photostream/) is modified, it's more powerful than the one at left. It waits for motocross suspension to be installed
[09:56:36] <pfred1> I'd have still bought it even if I knew htough
[09:56:56] <pfred1> mazafaka no your wooden boxes
[09:57:26] <pfred1> about all I know about motorcycles is they're 3 wheels shy of me wanting to operate one
[09:57:57] <mazafaka> pfred1: I created a table for PC on which I was capable to draw on A1 paper format when I was young. I once used drill and grind wheel for angle grinder to cut 20 mm -thick plywood
[09:59:07] <pfred1> I ripped this on my old outfeed setup
http://img195.imageshack.us/img195/2033/shelfy.jpg
[09:59:17] <mazafaka> pfred1: Suitable rooms in Russia are garages, or whatever built on a private territory, so many people simply lack the space for their art
[09:59:21] <pfred1> that's a big box huh?
[09:59:54] <pfred1> I made 2
http://img9.imageshack.us/img9/508/shelves.jpg
[10:00:21] <pfred1> mazafaka Russa is such a big country too what do you people do with most of it?
[10:01:24] <mazafaka> well, Soviet Union has given us tiny garages. Soviet worker ought to dinner at the dinner room of the plant and buy a tiny garage for his car
[10:01:49] <pfred1> I park my cars out in the yard
[10:02:11] <pfred1> I need a new outbuilding
[10:02:22] <mazafaka> I live in a block of flats, habing a barn and a garage at different places in the town.
[10:03:01] <pfred1> now I work in an attached garage but I'm not too keen on open flames in it being as it is attached to where I live
[10:03:29] <pfred1> if i had a detached outbuilding I'd be more into doing like forging and that sort of work in it
[10:03:53] <pfred1> I do weld a little in my garage though
[10:05:40] <mazafaka> well, I'm lacking money a little for this all. Otherwise, I would repair this all and also buy a cottage (About 15k USD) in the same town in addition to my apartment
[10:06:41] <mazafaka> All must be safe enough, be it welding or wood-working.
[10:06:46] <pfred1> a little bit of it is money mostly it is pretty convenient to work attached to the housel ike if i want to go in and grab a bite to eat or something
[10:07:04] <pfred1> but I am out of room at this point
[10:07:28] <pfred1> I passed up on a couple of upright bandsaws because i don't know where I'd put them
[10:07:53] <mazafaka> But I cycled to the garage at winter (about 10 minutes):
http://www.flickr.com/photos/ilyagalkin/6877880229/in/photostream
[10:07:59] <pfred1> I really could use one of those too
[10:08:17] <pfred1> mazafaka now that is dedication!
[10:08:41] <mazafaka> When your shop is far you can not use your time efficiently. E.g. I would like to wash clothes and cook while I think of something related to my work
[10:08:42] <pfred1> it has been so mild this winter we barely got a dusting of snow this year
[10:09:06] <mazafaka> we also
[10:09:17] <mazafaka> it's super warm in this winter.
[10:09:23] <pfred1> mazafaka this was 2 years ago
http://img514.imageshack.us/img514/3994/shoveled.jpg
[10:09:27] <mazafaka> it's already a spring here
[10:09:32] <pfred1> I shoveled all of that by hand
[10:10:00] <pfred1> that isn't even all of my driveway
[10:10:08] <pfred1> there is more to the left out of frame
[10:10:18] <mazafaka> our cottages use to have 20x30 meters gardens.
[10:10:27] <pfred1> I have a garden
[10:10:52] <pfred1> http://i.imgur.com/HzYVU.jpg
[10:10:54] <mazafaka> i wouldn't build something casting shadows
[10:11:36] <pfred1> I put this into my garden last year
http://i.imgur.com/MdPJ9.jpg
[10:12:39] <pfred1> http://i.imgur.com/lt6hi.jpg
[10:12:50] <mazafaka> Nice, but try to keep it virgin, just take away some tall and nasty grass
[10:13:28] <pfred1> someday I want to set it up to have an endless waterfall stream or something
[10:13:59] <pfred1> but this is just my first year out with the pond i figure it'll grow over time
[10:14:18] <mazafaka> When I will have bought a car I think I will consider buying a cottage. it's just some building on a territory of 20 by 30 meters, or more
[10:15:00] <pfred1> this is my house
http://i.imgur.com/leC6i.jpg
[10:15:06] <pfred1> with my garage
[10:15:19] <mazafaka> pretty big garage...
[10:15:29] <pfred1> it is 20x20 feet
[10:15:31] <mazafaka> Do you work in the garage?
[10:15:36] <pfred1> not sure what that is in metric
[10:15:39] <pfred1> yes
[10:16:22] <mazafaka> My garage's door are very low. I will have to disassemble the soft top of my SUV to park it in the garage.
[10:16:36] <mazafaka> one foot = 0.3 meter
[10:16:37] <pfred1> this is sort of old but what my garage used to look like
http://www.instructables.com/id/My-Mixed-Media-Garage/
[10:17:02] <pfred1> parts of it look the same i guess but I'm always upgrading
[10:17:20] <mazafaka> What if you regroup the tools used?
[10:17:35] <pfred1> they're pretty rationaly laid out now
[10:17:59] <pfred1> like I have my welding corner next to my metal working area then the other side is for woodworking
[10:18:32] <pfred1> oh and i have a corner for doing electronics too
http://www.instructables.com/id/Pauls-Electronics-Pit/
[10:18:56] <mazafaka> But I plan to have a motorcycle, motorcycle with sidecar, and 3.8x1.9 meters SUV - all on the territory of 3.6x5.6 meters.
[10:19:03] <pfred1> but i had to cut back on that I'm using half of that desk for my CNC machine now
[10:20:50] <mazafaka> cottages offer a lot to its owners... I would keep all the vehicles utside but protect them from rain and snow.
[10:21:34] <pfred1> yeah i leave my cars and trucks outside
[10:21:58] <jdhnc> my wife parks in the garage. Huge waste of space having to leave room for a car.
[10:21:59] <mazafaka> But we only can think of buying a car this year, and some repairs in our apartment... Then we can take a loan...
[10:22:08] <pfred1> man i need batteries for my camera
[10:22:35] <pfred1> I don't have any pictures of my new saw
[10:22:52] <pfred1> I got it with a case and everything
[10:23:04] <mazafaka> tell her she's 'obolete' or something. Imagine a 'Texas husband' out of yourself, jthornton, drink some alcohol before it to be brave enough!
[10:23:05] <mazafaka> :)
[10:23:13] <mazafaka> *obsolete
[10:24:17] <pfred1> ah booze being liquid courage reminds me of the movie I watched last night barfly
[10:24:52] <pfred1> jdhnc cari n garage is great excuse to build a dedicated outbuilding
[10:25:31] <pfred1> when I do I'm going at least 20x60
[10:25:42] <pfred1> skip this running out of room noise
[10:25:52] <mazafaka> Wouldn't dedicated outbuilding be too pricey?
[10:26:15] <mazafaka> pfred1: but good for keeping the noise inside
[10:26:21] <pfred1> maybe concrete is awfull expensive anymore
[10:26:44] <pfred1> but my property is all sand so I'm wondering if i coudn't just make my own
[10:27:08] <pfred1> I could dig a big pit in the back where i never og anyways
[10:27:09] <mazafaka> In summer, all the noise and dust from paint is still in my garage. Then it's mixed with dirt and some wood chips and gets utilised
[10:27:37] <pfred1> mazafaka this is part of my back yard
http://img717.imageshack.us/img717/8292/p2200017.jpg
[10:29:20] <pfred1> mazafaka my garage I'm in now has a high ceiling and I've noticed with a high ceiling dust doesn't travel as far
[10:29:30] <pfred1> its strange
[10:29:47] <pfred1> it goes up then pretty much comes right back down
[10:30:17] <pfred1> my old garage had a much lower ceiling and the dust did go everywhere in it
[10:30:32] <deuplonicus> Hi guys! I'm a new LinuxCNC user!
[10:30:44] <pfred1> deuplonicus good stuff huh?
[10:30:55] <archivist> make stuph then
[10:31:12] <deuplonicus> I think so, so far I've only set the basics, I am finishing wiring the Joes hybrid R&P we made today
[10:31:22] <pfred1> archivist I can't go out and get materials until I unload my van
[10:31:42] <deuplonicus> I need to "Break it in" though, any ideas on how to make the machine go back and forth on all axes all day?
[10:32:32] <pfred1> couldn't you code a G Code loop?
[10:32:34] <vin321> are thease any good 3179 - Standalone / Computer Controlled Unipolar Stepper Motor Driver ?
[10:33:05] <pfred1> vin321 Unipolar stepper motors are usually less powerful than bipolar ones
[10:33:19] <mazafaka> pfred1:
http://img717.imageshack.us/img717/8292/p2200017.jpg is a virging groung. make it wet with the hose regularly during summer and it will be perfect.
[10:33:33] <pfred1> theoretically being unipolar the drivers are easier to make
[10:34:04] <pfred1> mazafaka yeah in the summer i have it all cleaned up just a field of grass then
[10:34:23] <pfred1> I even chopped out that whole center mess
[10:34:24] <deuplonicus> pfred1, I suppose I could, the problems lies within me, I've never done gcode before
[10:34:30] <archivist> vin321, bipolar drive is far better
[10:34:45] <mazafaka> pfred1: I would use relatively small workshop, but rearranging the stuff thoroughly. Some tools... they are of not use...
[10:34:49] <pfred1> archivist can be usually is doesn't HAVE to be though
[10:35:08] <vin321> kk ty
[10:35:21] <pfred1> vin321 the real question is what do you plan to do with it
[10:35:44] <archivist> he has the right motors for bipolar iirc
[10:35:47] <vin321> so whats the best driver i can get for under £ 30 in you opinion ?
[10:35:50] <mazafaka> pfred1: Also, good trees and soil full of roots protect from wind and water and soil erosion
[10:35:51] <pfred1> I mean if all you're doing is making mirror stages for a laser
[10:36:21] <vin321> its a router with a gantry
[10:36:23] <deuplonicus> Can anyone suggest the best way for me to learn gcode and loops?
[10:36:29] <pfred1> vin321 what do you want to do with it?
[10:36:49] <archivist> deuplonicus, by doing and looking at some of the samples
[10:36:52] <vin321> wood ally i guess
[10:37:03] <pfred1> vin321 so you want to build a wood router?
[10:37:16] <deuplonicus> are the samples on linuxcnc.org?
[10:37:31] <vin321> i kind have but i smoked my tb bord
[10:37:40] <pfred1> deuplonicus linuxcnc comes with sample files
[10:37:44] <vin321> need to replace it for someing that dont pop
[10:38:00] <pfred1> vin321 what input voltage?
[10:38:33] <vin321> http://www.ebay.co.uk/itm/3-Stepper-Motor-4Nm-Nema23-566oz-1yr-Warranty-cnc-parts-/110824545855?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item19cda85e3f
[10:38:35] <pfred1> the 32 VDC they say those htings will operate at is a bit optimistic
[10:38:39] <vin321> im driving them
[10:39:15] <pfred1> vin321 I did this with a TB6560AHQ driver
http://www.youtube.com/watch?v=fHPKaHLzXes
[10:39:16] <vin321> well the higher the better id have thort
[10:40:40] <pfred1> I made it all the way to 1.7 IPS when I changed to eighth micro-stepping too
[10:40:54] <pfred1> which is 102 IPM
[10:41:27] <pfred1> but i run at only 24VDC
[10:41:52] <vin321> i got the TB6560AHQ bord runing pritty well b4 poping it
[10:42:19] <pfred1> so what caused the failure? can it be avoided?
[10:42:27] <pfred1> the TB6560 ICs are cheap to replace
[10:42:50] <pfred1> cheaper then buying new drivers
[10:42:51] <vin321> i have 5 spear about here somne where
[10:43:21] <vin321> but allkindsa stuff smoked
[10:43:31] <vin321> smelt like some caps went
[10:43:38] <pfred1> oh so more than the driver ICs burnt up on you?
[10:43:52] <pfred1> what are you using as a power supply?
[10:43:54] <vin321> some of the other is'd smonked to
[10:44:32] <deuplonicus> pfred1 thanks I wasnt aware there were samples on linuxcnc
[10:44:43] <vin321> i was useing a pc psu +12 to -12
[10:44:45] <pfred1> deuplonicus there are samples in linuxCNC
[10:44:53] <pfred1> deuplonicus like they just come with it
[10:44:58] <vin321> that woukded ok for a while them died
[10:45:05] <deuplonicus> sweet, glad to know
[10:45:20] <pfred1> like go file open in axis and navigate to the samples directory
[10:45:22] <deuplonicus> I don't have my machine in front of me, but I will be on it later today
[10:45:46] <deuplonicus> thanks! I didn't know until just a bit ago this chat existed, tons of help already!
[10:45:50] <pfred1> also in the scripts there are g code generators too
[10:46:06] <deuplonicus> nice!
[10:46:11] <pfred1> that can make you g code if you feed it text or an image
[10:46:12] <vin321> so i got my e bike battrys out & charger 48 v & taped off 36 v from the batttrys
[10:46:35] <pfred1> yes 36 and 48V are too high for a TB6550 to handle
[10:46:43] <vin321> it worked but sonded crap so i changed it back to 24 & it poped
[10:46:58] <vin321> well it was 36
[10:47:13] <pfred1> I think you're gong to have to address your power supply before yo ucan expect to make real progress
[10:47:18] <vin321> the 48 was throw 4 battrys i used 3
[10:47:28] <vin321> ra
[10:47:30] <vin321> ya
[10:47:46] <pfred1> tb6560s can't evne handle the 32V that is claimed due to back emp issues
[10:47:54] <pfred1> emf even
[10:47:56] <pfred1> not emp
[10:48:09] <pfred1> emp is after they blow :)
[10:48:22] <deuplonicus> haha
[10:48:34] <pfred1> they go up like little nukes
[10:48:46] <pfred1> but if you feed them right they work OK
[10:49:27] <pfred1> vin321 I made my own drivers
http://www.instructables.com/id/TB6560-Microstepping-Bipolar-Chopper-Stepper-Motor/
[10:49:35] <pfred1> but I don't reccommend anyone else to do it
[10:50:27] <deuplonicus> haha, why not?
[10:50:38] <pfred1> without a good power supply any stepper driver isn't going to work like it should
[10:50:50] <pfred1> because it is a lot of work and you can buy them for so cheap
[10:51:13] <deuplonicus> true, I only make PCBs when it is absolutely necessary
[10:51:21] <pfred1> your power supply is your foundation your whole system runs off but it is one of the most overlooked components
[10:51:38] <mazafaka> jthornton: speaking of trikes and sidecars, would you buy e.g. Zero S aor Brammo's electric motorcycles?
[10:51:54] <pfred1> this is the power supply I built
http://www.instructables.com/id/300-Watt-Linear-Power-Supply/
[10:52:06] <pfred1> more than is needed but doesn't hurt to have
[10:53:17] <pfred1> some of them surplus switching power supplies you don't know what kind of power they're really putting out
[10:53:53] <pfred1> in CNC what you don't know will hurt you eventually
[10:54:02] <archivist> Coutant Lambda switchers are ok
[10:54:14] <deuplonicus> haha, nice instructables collections
[10:54:28] <deuplonicus> will read more
[10:54:40] <pfred1> deuplonicus well for full disclosure this is another of my articles
http://www.instructables.com/id/Parallel-Port-Break-Out-Board-BOB/
[10:55:04] <pfred1> though that circuit appears to have some kind of a bug in it
[10:55:26] <pfred1> because when i don't have it energized but plugged into a port one of the power LEDs glows dimly
[10:55:49] <pfred1> I mean it doens't seem ot hurt anything but the fact that it does it still bugs me
[10:56:07] <pfred1> not enough to have fixed it yet though :)
[10:57:02] <deuplonicus> lol, I know the feeling, magic circuit problems that don't cause problems
[10:57:26] <pfred1> yeah well i haven't used the inputs yet on it so it might in fact have real problems i need to address
[10:57:38] <pfred1> works for running stepper drivers though
[10:57:57] <deuplonicus> hah
[10:58:36] <pfred1> yeah I never did fiddle with the inputs and i know one of them is total horse picky too I didn't feel like throwing another opto on it and had some free gates on the board
[10:59:20] <vin321> i bypassed the opto on my tb b4 i killed it
[10:59:30] <pfred1> so the no follow through speech is applicible with that project as it stands
[10:59:42] <deuplonicus> eh, it happens
[11:00:01] <pfred1> I found if i didn't use optos wiht my motor drivers on the step and direction lines they'd interfre with each other
[11:00:18] <pfred1> I learned that lesson the hard way
[11:00:31] <deuplonicus> ooo
[11:00:52] <archivist> bypassing optos is a good way to kill stuff
[11:00:55] <pfred1> well I was tearing my hair out trying to debug motor drivers when I hooked 2 up
[11:01:26] <vin321> you think good chance my mother bord will need replacesing ?
[11:01:30] <pfred1> archivist it didn't "hurt" anything but just the noise that'd propigate on the lines nothing worked either
[11:01:49] <pfred1> the drives would run really sickly
[11:02:01] <archivist> noise spikes can be very large
[11:02:10] <pfred1> yeah it was out of control
[11:02:18] <pfred1> like junk the lot of it kind of a thing
[11:02:25] <vin321> i only bypaeed the opto on the strp
[11:02:29] <vin321> step*
[11:02:50] <pfred1> one thing i noticed on TB6550s is they need pretty wide step pulse widths
[11:02:51] <vin321> that redused the noise a lot allso
[11:02:54] <pfred1> 5000ns
[11:02:59] <archivist> bypassing any means you connected gnd together
[11:04:04] <pfred1> even though I hate opto delay with a step width like that the opto delay hardly matters anymore
[11:05:00] <archivist> there is little/no delay cause by the opto, more likely your opto driving conditions are wrong
[11:05:19] <pfred1> funny that isn't what I've read everywhere else
[11:06:00] <pfred1> or seen on my oscilloscope for that matter
[11:06:11] <archivist> some dont understand the current needed to fully drive the led in the opto
[11:06:22] <pfred1> don't count me in that group
[11:06:27] <vin321> i couldant say all i know is it nealy fixed the sound & it stoped missing steps or missed so few that i couldant tell
[11:06:31] * pfred1 used 11 ma
[11:07:03] <pfred1> more didn't make it appreciably faster
[11:07:21] <pfred1> I was saturated at that point
[11:07:46] <pfred1> optos are an order of magnitude slower than TTL logic
[11:07:53] <pfred1> just how it is
[11:08:13] <mazafaka> need to reboot to linux
[11:08:50] <pfred1> you're going to take a 10X speed penalty hit going through an opto compared to a TTL gate
[11:09:55] <archivist> rather sweeping statement
[11:10:31] <pfred1> well unless you get some esoteric optos they're out there
[11:10:46] <pfred1> but you ain't buying them for no quarter a package
[11:12:21] <pfred1> I used 2 optos in my circuits some really slow ones then some mid speed onses after I became aware of the issue
[11:13:19] <pfred1> some optos are measures in milliseconds
[11:17:14] <pfred1> in any event the circuit I designed for my optical isolation has worked out here well enough for me
[11:21:51] <pcw_home> there are fast optos (al though the new transformer/capacitive isolators are better/cheaper now days)
[11:22:30] <pfred1> pcw_home the second optos i bought would be considered fast compared to the first one I got involved with
[11:23:14] <pfred1> but in the world of high speed electronics you could still string together a few and make a nice delay line out of them
[11:23:46] <pcw_home> What I like about the new isolators is that they dont have drive related assymetry in on/off times
[11:24:25] <pfred1> yeah I had to clean up my optputs using schmidtt triggers
[11:24:53] <pfred1> the signals coming out of optos aren't exactly square up and down
[11:25:08] <pfred1> more like bumps and humps
[11:25:53] <pcw_home> The new isolators are perfect in that respect, the disadvantage of the new isolators is tha they require power on both sides
[11:26:00] <pfred1> I used 7414s worksed liek a charm
[11:26:29] <pfred1> well my opto circuits needed power on both sides you have an LED and a photo transistor nothing passive there
[11:28:09] <pcw_home> But optos still suffer from the driver related assymetry (drive them harder and the turn on time gets faster but the turn off gets longer)
[11:28:11] <pcw_home> so if you want the to not cause a lot of distortion you have to tweak the drive (and they are wildly different from opto to topto)
[11:29:22] <pcw_home> So we only use optos where speed is not an issue or whwre there no power available on tje LED side
[11:29:51] <pcw_home> man my ytping is disinegrating
[11:29:58] <pfred1> you mean where there is no more power than what it takes to light the LED?
[11:30:13] <pfred1> because that is some power
[11:30:44] <pfred1> one of my optos i think had 20 ma max for the LED
[11:30:52] <pfred1> something crazy
[11:31:23] <pfred1> but like you said go to the top of that and you're getting distortion
[11:32:04] <pcw_home> The newer isolator require a 3.3 or 5V PS on both sides (in addition to the signal)
[11:32:06] <pcw_home> they are more like gates/buffers
[11:33:23] <pcw_home> but they go to 100 Mbit/s and run on 3.3v (most faster logic OPTOs need 5V)
[11:33:28] <pfred1> hey if it is a drop it in and go solution I think it is worth it
[11:34:55] <pfred1> what i ended up doing was using the opto then feeding its output into a buffer gate just to clean it up
[11:35:23] <pfred1> so these new isolators sound easier to use to me
[11:36:58] <pfred1> why i had to use the optos was because of inductive noise made by my stepper motors in the drives
[11:37:28] <pfred1> I guess the drives themselves being PWM aggrivated it I don't know
[11:38:02] <pfred1> all I know is when I tried to run 2 drives they'd interfere with each other so badly neither would run right
[11:38:18] <pfred1> optos on the step and direction lines cleaned it right up though
[11:39:21] <pcw_home> Yes its easy to get high frequency current causing ground bumping
[11:40:10] <pfred1> two drivers at once was a big hurdle for me
[11:40:24] <pcw_home> every wire is rubber band at MOSFET switching edge rates
[11:40:42] <pfred1> yeah it was a lot like rubber bands twanging away
[11:41:14] <pfred1> it was sheer chaos
[11:41:44] <pfred1> optos are like putting the crazies into their own separate rubber rooms though
[11:43:29] <pcw_home> Yep. You have VBUS square waves driving into the step motor coils --> frame capacitance
[11:43:31] <pcw_home> so you have essentiallyl unlimited current bumpimg your step driver boards ground around
[11:43:59] <pfred1> yeah as I designed drivers I kept on thinking about ways of soaking noise up
[11:44:21] <pfred1> strategically locating capacitors on the boards
[11:44:39] <pfred1> but I can only manage to sponge so much of it up
[11:44:54] <pcw_home> A common mode choke on each step motor pair will help some
[11:45:04] <pfred1> PWM stepper morot driver circuits are basically noise makers
[11:45:17] <pcw_home> (and also help reduce radiation)
[11:45:27] <fragalot> pfred1: depends on the pwm fequency
[11:45:46] <pfred1> fragalot only in so far as where the noise shows up
[11:45:53] <pcw_home> its not the frequency so much as the edge rates
[11:45:54] <fragalot> good point.
[11:45:58] <pfred1> what harmonics it manifests itself as
[11:46:14] <pfred1> you're gonna get noise
[11:46:52] <pfred1> weren't the original radios basically coils with spark gaps?
[11:48:39] <pcw_home> yes spark gaps and coherers
[11:48:41] <pcw_home> When a MOSFET turns on into the step motor winding capacitance there is nothing to limit the current except the wiring inductance
[11:48:43] <pcw_home> (which is why the common mode choke help so much)
[11:48:55] <pfred1> much as I'm into electronics my interest never went towards radio much
[11:49:47] <pfred1> it is a bit fascinating I suppose just never fascinated me much except on the most technical level nothing practical though
[11:50:15] <pfred1> I went to a QC fest here once but man the goofs i met there no thanks!
[11:50:46] <pfred1> none of them built their own rigs
[12:08:09] <pcw_home> Yeah with no code requirement its sort of like CB
[12:39:04] <IchGuckLive> hi all around the globe
[12:39:21] <IchGuckLive> hope all USA folks did servive this storm days
[12:40:55] <pcw_home> Makes me glad to live in earthquake (and not tornado) country, at least until the next big one...
[12:41:28] <IchGuckLive> pcw_home: this is mesa proving shake
[12:41:42] <IchGuckLive> like nasa test pattern
[12:41:59] <IchGuckLive> B) O.o
[12:42:40] <pcw_home> :-)
[12:42:57] <IchGuckLive> CA LA or SF
[12:45:53] <pcw_home> SF bay area (right on top of the Haward fault which is overdue for a 7 or 8 magnitude shaker)
[12:46:32] <IchGuckLive> is there a law to get 2day servivel kits in the hose ready
[12:47:11] <pcw_home> no law but good common sense
[12:48:19] <IchGuckLive> i have been 10days in torrance last month for haas expo to a new mashine style
[12:48:36] <IchGuckLive> http://maps.google.com/maps?q=580%20Madrid%20Avenue+Torrance,%20CA+90501
[12:51:20] <pcw_home> Only been to LA once (but in LAX many times)
[12:51:42] <IchGuckLive> B)
[12:54:44] <anonimas1> grr. stupid fanuc.
[12:56:14] <anonimas1> why the hell dosent it understand full auto.
[13:04:31] <pcw_home> You're not speaking to it nicely?
[13:06:38] <archivist> not flicked the step/run switch (if it has one)
[13:09:11] <anonimas1> it flicks itself on after every line.
[13:22:05] <anonimas1> :/
[13:56:44] <raynerd> Hi, I have a 2mm lead screw on both my x and y axis, yet my movement on the y axis is being elongated...
[13:56:51] <raynerd> any thoughts on why this is happening
[13:56:59] <raynerd> it looks to be about double.
[13:57:08] <fragalot> raynerd: half-stepping on the x and full step on the y ?
[13:57:56] <raynerd> I`m using TB6560 and they aren`t currently next to me, but almost certain I have them all set to half stepping.
[13:58:06] <raynerd> infact, I`ll go check
[13:58:40] <archivist> irc from the machine!
[13:58:52] <fragalot> I'm assuing the x & y motors are the same type, so don't think that'l be the cause .. and i'm also assuming that you've verified that the settings are the same in emc too
[13:59:10] <raynerd> lol, archivist, I think you may remember our discussion about my network adaptor not working with linux
[13:59:20] <raynerd> hence No IRC from the machine!!!!!!
[13:59:21] <archivist> wire!
[13:59:31] <raynerd> you have one?
[13:59:37] <fragalot> in which case, if it's not the controller's stepping config, i'm out of ideas. :P
[14:00:04] <archivist> one can make a mistake in stepconf too
[14:00:28] <raynerd> fraglot, emc settings are identical as I have flipped between the two pages and checked
[14:00:33] <raynerd> motors are the same
[14:05:14] <JT-Shop> raynerd: if you can figure out why your not getting the expected distance then change the scale to match
[14:05:36] * fragalot assumes JT-Shop meant "can't" :/
[14:05:50] <JT-Shop> a good assumption
[14:05:51] <fragalot> also you're * ... one of my pet peeves :P
[14:05:58] <JT-Shop> :/
[14:06:01] <fragalot> sorry
[14:06:29] <fragalot> but your & you're are 2 completely different beats and it kills a kitten everytime someone gets it wrong :P
[14:06:37] <fragalot> beasts*
[14:07:15] <JT-Shop> yea, if it don't sound correct when you say you are then don't use you're
[14:07:46] <fragalot> yep
[14:07:48] <raynerd> Well thanks for all you`re help, I`m really please your trying for me.
[14:07:51] <JT-Shop> and it seems the race is off...
[14:08:08] <fragalot> raynerd: I see what you did their.
[14:08:22] <archivist> wrong there!
[14:08:28] <fragalot> xD
[14:08:34] * archivist giggles
[14:08:41] <raynerd> :P
[14:09:39] <raynerd> Eats shoots and leaves - take it you have read it?
[14:10:15] <archivist> anyway a dti and use it to measure each axis to see which one is set incorrectly
[14:10:59] <JT-Shop> or give it 400 steps and see if the stepper turns one time
[14:15:16] <raynerd> ok, I`m at my machine now
[14:15:56] <raynerd> just while I`m booting up. Random question - should you oil slides with bushes?
[14:16:44] <archivist> probably yes
[14:21:03] <fragalot> i'd probably use graphite in an attempt to keep it from clogging up like it would with grease
[14:21:19] <fragalot> (used grease on my mill and... oh god the mess)
[14:21:51] <archivist> if covered properly no mess :)
[14:22:57] <raynerd> OK
[14:23:03] <raynerd> it seemed to be the current settings?
[14:23:14] <raynerd> one axis was set with 25% and the other 50%
[14:24:22] <archivist> "<raynerd> it seemed to be the current settings? " you gave us no numbers so we cannot tell
[14:24:53] <raynerd> what numbers do you want to see?
[14:24:57] <raynerd> I`m not clear.
[14:26:05] <archivist> what setting you have for micro steps on the two axes and what the scale factor you have in your config
[14:28:36] <raynerd> I have the microstepping to half step as you discussed with me and recommended about a week ago
[14:28:54] <raynerd> and scale factor? I have 2 for microstepping in emc setup config
[14:28:55] <archivist> for x AND y?
[14:29:10] <raynerd> they are now all set the same, x y z, 1/2 step
[14:33:23] <archivist> how many steps per rev have you set, how many revs per in have you set the leadscrew
[14:34:50] <raynerd> 200
[14:35:04] <raynerd> and 2mm pitch on the leadscrew
[14:36:45] <archivist> is the oval exactly 2 to 1
[14:37:07] <raynerd> archivist - it is now sorted :D
[14:37:15] <raynerd> it was the current settings
[14:45:29] <pcw_home> maybe your "current settings" are really step settings
[15:11:18] <raynerd> humm, I can`t see it as the dip switches for step settings are next to it, however it is now cured
[15:11:51] <archivist> you didnt say what you changed to fix it
[15:12:31] <raynerd> current settings...a few lines up...
[15:12:49] <raynerd> I wrote,... OK,, it seemed to be the current settings...one axis was set to...
[15:12:51] <Dave911> Peter... is the Mesa_7i65 component part of the LinuxCNC source code distribution? I did a git clone last night of 2.5_branch and the Mesa_7i65 component in not in the source code and is thus not compiled.. so my machine config does not run..
[15:13:10] <raynerd> with both the current settings set the same, it seems OK
[15:13:21] <Dave911> I thought it was there before..
[15:13:45] <raynerd> But I have a new issue...seemingly randomly, I`m getting my images plotted on the wrong place
[15:13:54] <raynerd> as though it is missing steps perhaps?
[15:15:00] <raynerd> so like if I have two circles one bigger than the other and concentric, it`ll end up plotting the second with them crossing.
[15:15:07] <raynerd> but then sometimes not!
[15:15:52] <raynerd> maybe it is this 12v power supply issue...as we determined yesterday, it really isn`t high enough I guess
[15:15:54] <archivist> you should be able to hear steps being missed
[15:16:16] <raynerd> hear them?
[15:17:46] <raynerd> like a cranking noise?
[15:19:31] <raynerd> archivist...what do you mean?
[15:24:44] <Dave911> pcw_home .. are you there?
[15:26:03] <pcw_home> Yes I dont see it either, maybe it was never commited
[15:26:37] <raynerd> :-(
[15:30:00] <raynerd> maybe my velocity is set too high :S
[15:33:04] <Dave911> OK.. I'm going to copy the source from a slightly earlier version and see if I can compile it.. I didn't think I had to copy it in before. Thanks..
[15:33:10] <pcw_home> EMC:03andypugh07master * r98b0db19446a10/src/hal/drivers/mesa_7i65.comp More fixes to the true != 1 oversight.
[15:33:11] <pcw_home> it was in master at one point (that commmit was on 11/12/11
[15:33:55] <fragalot> raynerd: either your velocity, or the ramp-up speed (nfc what it's called in emc)
[15:34:06] <Dave911> OK... good so I am not losing my mind. :-)
[15:34:18] <fragalot> raynerd: if your voltage is too low, you'll have less torque and won't be able to speed up as quickly as you would with a higher voltage psu
[15:34:43] <fragalot> I used to run 2V steppers on 24V on my first diy :P
[15:35:32] <Dave911> The EMC/EMC2 name change to LinuxCNC is a PITA... it broke a few things in my configuration.
[15:35:58] <raynerd> just going to test with a slower speeds
[15:36:18] <raynerd> I will get a bigger psu, just need to decide which and find one at a reasonable price.
[15:36:47] <raynerd> I`m aactually sat here waiting for it all to cool down. It was running on the last test for about 15 mins and the motor is really hot
[15:36:49] <raynerd> especially the z
[15:37:18] <gene77> Hi guys - I need a QD formula I can put in an ngc file to caculate a 2 degree taper on a .001" per full circle g2 cut resolution. Any math wizards here?
[15:38:04] <gene77> Using g2, from y0.0 variable x & I is the target
[15:39:21] <gene77> IOW I need to cut a cone with a 2 degree exandibg with depth taper
[15:39:37] <Dave911> JT-Shop ... I made a couple of Wiki changes so the directions are correct on compiling LinuxCNC from Git (otherwise the directions were wrong - things don't work ) .... There are a few other EMC/EMC2 mentions.. Do you want us to change the titles also.. I don't know what the name change plan is and didn't want to overstep.
[15:39:39] <Dave911> Some things seem to be changed and others not so far...

[16:19:27] <educa> Is there anyone online who would be willing to help me a little with some info about using mesa card for hardware step generation? I currently have a 3 stepper + 1 pwm + some in and outputs working on parallel port, but I'd like to be able to get better/faster steprates. Only problem is I don't understand a thing about these mesa cards. I have discovered that I probably need a 7i43
[16:20:55] <pjm> i have a 7i43 card
[16:21:17] <pjm> sounds like u have a machine pretty similar in terms of IO to my machine
[16:21:35] <pjm> i went from parport to mesa for better step gen + a lot faster encoder inputs
[16:21:44] <pjm> for spindle speed etc
[16:26:37] <pcw_home> do you have a breakout card on your parallel port currently?
[16:30:19] <pcw_home> If you do, a 5I25 might be a better choice as it would allow you to keep using your Breakout card
[16:39:06] <educa> I currently have nothing
[16:39:30] <educa> I need to achieve at maximum 50kHz steprates
[16:45:19] <Jymmm> LOL
http://i39.tinypic.com/2vbao78.jpg
[16:48:57] <pcw_home> 5I25 is good for ~8.3 MHz step rates
[16:49:33] <pjm> whats the 7.43 max rate again, i know the encoder sample rate is way high
[16:49:38] <pjm> 7i43 i mean
[16:50:25] <pcw_home> 7I43 is 12.5 MHz max (its ClockLow/4) 7I43 ClockLow is 50 MHz, 5I25 Clocklow is 33 Mhz
[16:51:42] <pcw_home> not that that makes any practical difference, even with 256 uStepping a few hunderd KHz is enough
[16:53:17] <pcw_home> even a step/dir driven servo with a 8000 line = 32000 count encoder is only 1.6 MHz at 3000 RPM
[16:57:07] <Thetawaves> you are talking serious issues electrically when you get to those speeds
[16:57:49] <pjm> yeah my spindle encoder is i think 360ppr i/q and the 7i43 doesnt even blink at 6K rpm spindle speed
[17:01:13] <pcw_home> Most encoders only get to a few hundred KHz
[17:01:45] <Thetawaves> your cables can only be a few feet with signals that fast
[17:04:15] <pcw_home> Differential signals can deal with MHs rates But I think its hard to make the encoder optical detectisr fast enough
[17:05:38] <Jymmm> Uh, um,

[17:06:05] <Jymmm> Indian Laborers
[17:06:26] <djdelorie> what about magnetic isolators instead of optical ones?
[17:09:23] <pcw_home> This is on the quadrature encoders, they rarely get above a few hundred KHz (that is when you go to higer resolutions they drop the max RPM)
[17:09:25] <pcw_home> and I _think_ its due to the photodiode frequency response
[17:10:15] <Dave911> pcw_home I copied the mesa_7i65.comp file from the software - master as of December and put it in the current software - and it doesn't compile. It complains of having "no function" and stops the compiler. On the December version the compiler complains only with a warning of an unused variable.
[17:10:17] <Dave911> Someone must have pulled the module out of the source. I'll try and fix it. I'll stick in a dummy function if I need to just to make the compiler happy.
[17:11:36] <pcw_home> and Andy is sailing round-the-world...
[17:11:57] <Dave911> What an excuse ... I'd send Andy an email... but I doubt he has internet.. ;-)
[17:13:27] <Dave911> Apparently he *really* needed some time off!
[17:15:31] <pcw_home> I suspect lack of internet may be deliberate
[17:18:01] <pcw_home> there must be a commit in the logs for the removal, wonder if is was just a mistake of some kind?

[17:38:36] <Jymmm> well, cause and effect. What caused it, I don't know, that's just the effect
[17:38:45] <archivist> no, all gone to the pub
[17:38:57] <endercnc> mmm beer....
[17:39:05] <Dave911> Mistake .. could be. Or perhaps they found the component not compiling properly and yanked it out with the intention of having the component fixed..
[17:39:26] <Jymmm> gene77: There are some more intense photos if you're interested.
[17:39:35] <endercnc> what do you guys use to compile gcode?
[17:40:04] <archivist> one does not compile gcode
[17:40:26] <endercnc> generate*
[17:40:48] <archivist> serious difference, some use cam some write by hand
[17:40:58] <endercnc> and wouldn't simulating the toolpath based on the gcode be compiling it?
[17:41:09] <archivist> no

[17:41:53] <deuplonicus> hey guys, I'm setting up my machine on linuxcnc, I have a motor that I need to slave to the other for the gantry. wouldn't that be an XYZA setup? My question is why is A-axis set up in degrees? can I change it?
[17:42:23] <djdelorie> isn't A a lathe-like rotational axis?
[17:42:38] <archivist> a is a rotational axis
[17:42:49] <deuplonicus> well on my machine I have X, Y, Y2, and Z, a CNC router table
[17:42:59] <deuplonicus> do I use the XYZ setup instead?
[17:43:14] <archivist> you can look at the wiki there is/are examples
[17:43:14] <endercnc> are your y motors spliced together?
[17:43:43] <archivist> there is something called gantrykins too
[17:43:51] <deuplonicus> no, using the HobbyCNC board, there is X, Y Z and A (Y2) on the board, each motor has it's own SLA7078 IC
[17:44:44] <archivist> you are still slaving it to the other y look at the wiki examples
[17:44:52] <pcw_home> Jymmm: nice picture you would think that three different peoples with basically the same Abrahamic religion could get along, but No...
[17:46:07] <Jymmm> pcw_home: That one was the most dramatic. There are others (across decades) that are just as intense if you're so inclined

[17:47:47] <endercnc> deuplonicus: it looks to me that you would just wire them both to your y port one in a cw configuration and the other in ccw
[17:48:21] <endercnc> but im not super well versed in these things so dont trust me blindly ^_^
[17:48:31] <gene77> I just checked the docs for parameters, and it could be obtuse
[17:48:44] <archivist> homing is special with a gantry
[17:48:57] <deuplonicus> no endercnc, the driver board I have is designed to have four motors seperately connected
[17:49:20] <Jymmm> gene77: Did you see this one? Indian Laborers...

[17:50:06] <endercnc> hmm idk then ^_^
[17:50:42] <deuplonicus> I need to slave A axis to Y axis, is there a way to do that?
[17:50:58] <archivist> deuplonicus, see gantrykins

[17:52:12] <Jymmm> Here is a Georgia State Trooper in riot gear at a KKK protest in a north Georgia city back in the 80s. The Trooper is black. Standing in front of him and touching his shield is a curious little boy dressed in a Klan hood and robe. I have stared at this picture and wondered what must have been going through that Trooper’s mind. Before the Trooper is an innocent child who is being taught to hate him because of the color of his skin. The chi
[17:52:13] <Jymmm> ld doesn’t understand what he is being taught, and at this point he doesn’t seem to care. Like any other child his curiosity takes hold and he wants to explore this new thing that this man is holding probably because he can see his reflection in it and that’s a neat thing and he wants to check it out. In this picture I see innocence mixed with hate, the irony of a black man protecting the right of white people to assemble in protest a
[17:52:13] <Jymmm> gainst him, temperance in the face of ignorance, and hope that racism can be broken because this young boy may remember that a black man smiled at him once and he didn’t seem so bad after all.

[17:53:44] <endercnc> amazing picture O_O
[17:54:02] <deuplonicus> what is gantrykins? a kernel?
[17:54:05] <Jymmm> Yes, it is.
[17:54:21] <endercnc> gantrykins − A kinematics module that maps one axis to multiple joints
[17:54:40] <deuplonicus> how do I access it?

[17:58:32] <djdelorie> I once took a close up of a 1-year-old covered in birthday cake. Next day, had to send the camera in for repairs to get the frosting out of the lens mechanism.
[17:58:45] <djdelorie> she was faster than I was...
[17:58:47] <Jymmm> hahahaha
[17:59:08] <Jymmm> http://i54.tinypic.com/14cco4k.jpg
[17:59:11] <endercnc> deuplonicus it might just be me but it sounds alot like making a y harness and squaring up the steppers before hand is a much simpler method lol
[18:00:05] <endercnc> atleast that way you never run the risk of sending one stepper off without the other and bending stuff
[18:00:27] <deuplonicus> thanks endercnc
[18:01:00] <Jymmm> gene77:
http://i42.tinypic.com/t5r9ro.jpg
[18:01:22] <deuplonicus> what do you mean a y harness endercnc?
[18:02:13] <endercnc> what do you have electronics wise?
[18:03:31] <deuplonicus> a 4 axis stepper motor controller
[18:03:48] <deuplonicus> each axis can only handle the current of one motor
[18:04:14] <endercnc> its the hobbycnc 4 axis pro?
[18:04:20] <deuplonicus> yes
[18:04:34] <endercnc> allright give me a second to look it over
[18:04:57] <deuplonicus> word
[18:06:33] <deuplonicus> there is a hobbycnc selection in the stepconfg wizard
[18:06:49] <endercnc> lol that might make it easier
[18:07:00] <deuplonicus> i'm already using it
[18:07:23] <endercnc> did it work or are you still playing with it?
[18:07:35] <deuplonicus> but that selection isn't part of the "Axis configuration"
[18:08:02] <djdelorie> wire the two inputs to the Y and Y2 drivers in parallel, tell the software you only have one...
[18:08:07] <endercnc> ah i think i know what you can do
[18:08:30] <endercnc> do you have your machine all built?
[18:08:47] <deuplonicus> yes!
[18:09:08] <deuplonicus> hm... evidently I just froze linux
[18:09:09] <Jymmm> gene77:
http://i40.tinypic.com/262r01y.jpg
[18:09:12] <endercnc> any way you could remove one of the y steppers while we test this?
[18:09:46] <deuplonicus> yes, only one is connected, and I have the gear rack disconnected anyhow
[18:10:00] <endercnc> oh good okay heres what i would do
[18:10:02] <deuplonicus> rebooting machine....
[18:10:09] <endercnc> in the stepper config gui
[18:10:30] <endercnc> when you get to the page for setting up the pinouts for the parrallel port
[18:10:39] <deuplonicus> uh huh
[18:11:03] <endercnc> make pins 4 and 8 y step and make pins 5 and 9 y dir
[18:11:18] <endercnc> then click the "invert" check box next to pins 5 and 9
[18:11:42] <endercnc> hmm just the invert next to 8 sorry
[18:12:10] <Jymmm> gene77: Korean War Kitten
http://i43.tinypic.com/w7yl3p.jpg
[18:12:25] <deuplonicus> haha, ok, I'll test tht later without them connected to the rack, testing....
[18:13:03] <endercnc> then set up everything else as if you only had 1 y stepper it should send drivers y and A the same data with the direction of A being opposite of Y
[18:13:30] <deuplonicus> hmmm it doesn't move
[18:13:35] <deuplonicus> lemme check some pin assignments
[18:13:41] <endercnc> neither move?
[18:13:59] <deuplonicus> right
[18:14:01] <endercnc> if neither are moving then it might be another problem
[18:14:47] <endercnc> that setup shouldn't mess with the Y1 stepper working
[18:15:35] <deuplonicus> well it works without these mods
[18:16:03] <deuplonicus> hmmmm hold on let me finish something, I didn't finish wiring the other motors in
[18:16:46] <endercnc> that shouldn't effect the Y steppers working
[18:19:30] <deuplonicus> I only had one Y connected
[18:19:46] <endercnc> ah lol that might be why the other didnt work ^_^
[18:21:44] <deuplonicus> well, there's that, and a discrepency in the wiring diagram for the HCNC board, on one picture it shows com, a, A connected to Blue, Black, red. In another spot it says com, a, A connected to Orange, Red, Black
[18:22:03] <deuplonicus> but the other three colors maintain between the two
[18:22:08] <deuplonicus> so I'm like "...."
[18:22:25] <endercnc> lol cant help you there
[18:22:42] <endercnc> would need to see it in person to try and sort out a mess like that hehe
[18:23:28] <endercnc> from the pictures it looks like all the drivers are the same so if you wire the motors to them in the same fashion it should work
[18:23:52] <deuplonicus> oh ok, cool, yea they are all the same
[18:24:15] <endercnc> of course then if you wired them all up wrong they all wont work hehe
[18:27:26] <deuplonicus> well, I had that one working by testing the A axis
[18:27:34] <deuplonicus> the problem was it was all in degree/s
[18:28:37] <endercnc> hmm
[18:28:57] <endercnc> i'v never used a 4th axis with emc2
[18:29:18] <endercnc> so ive never played with degrees lol
[18:30:06] <deuplonicus> well, I was under the impression my second motor on my gantry was in theory a 4th axis, I didn't know I actually had to slave it
[18:31:34] <endercnc> idk im simple with my words lol
[18:32:14] <endercnc> you have 4 motors and 3 axis imo but i could be wrong because people name things oddly some times lol
[18:38:57] <deuplonicus> alright
[18:39:00] <deuplonicus> finished all my wiring
[18:39:08] <deuplonicus> if nothing is wrong, I shouldn't be doing that again anytime soon
[18:41:42] <endercnc> keep me informed ^_^ i just got my second cnc running today its such a wonderful experiance lol
[18:43:11] <deuplonicus> alrighty!
[18:43:40] <deuplonicus> got the Z moving, one Y (the non slaved one), and for some reason my X isn't working, nor the slaved Y with those changes to the pin configuration
[18:44:19] <endercnc> hmm
[18:44:50] <endercnc> goto the page with the z axis settings, are they the same as the x and y?
[18:48:28] <deuplonicus> well no, the limits and pitch are completely different as they should be
[18:48:32] <deuplonicus> but otherwise yes
[18:49:09] <endercnc> hmm
[18:49:40] <endercnc> the x and y2 dont move at all?
[18:49:45] <deuplonicus> nope
[18:49:55] <endercnc> do they power up? can you turn them by hand when they are on?
[18:50:01] <deuplonicus> hm....
[18:51:13] <deuplonicus> The X-axis spins extremely easy, but the Y2 is not moving, like it is connected
[18:51:37] <endercnc> the x axis wiring might be bad then
[18:51:55] <endercnc> the y2 hmm
[18:51:56] <deuplonicus> I seeee.... gayyyy
[18:52:28] <deuplonicus> yes the Y2 pin settings could be the culprit, I will double check the logic on the board tomorrow, it's getting cold in my garage at this hour
[18:53:00] <endercnc> lol
[18:53:05] <deuplonicus> and we've been hooking this up all day trying to finish (and hopefully celebrate) but, alas not entirely working tonight
[18:53:18] <endercnc> sorry to hear that
[18:53:27] <endercnc> dont lose hop
[18:53:31] <deuplonicus> hey thanks for the help!you and others here have been invaluable to my saying NO to Mach 3
[18:53:35] <deuplonicus> don
[18:53:47] <deuplonicus> don't worry, we've got tons of hope (we didn't vote obama)
[18:53:51] <endercnc> e i was up till 5 am last night and just got mine working 2 hours ago lol
[18:53:59] <endercnc> LOL
[18:54:01] <deuplonicus> oh lol
[18:54:18] <deuplonicus> alright man, take it easy. signing out
[18:54:18] <endercnc> and it was my second cnc hehe
[18:54:23] <endercnc> see ya

[19:27:17] <hatch789> or use it?
[19:27:37] <djdelorie> http://pastebin.com/
[19:28:40] <hatch789> http://pastebin.com/XtA0PtbC
[19:28:45] <hatch789> see if that works. Sorry about that
[19:29:11] <hatch789> I think all of the HOME_ stuff at the bottom is trying to move me right now
[19:29:20] <hatch789> rather than taking HOME as being right where I am at this moment
[19:32:02] <emperordane> anyone home?
[19:32:26] <emperordane> more specifically, anyone that could lend a hand with stepgen on a scara?
[19:33:25] <hatch789> I'm here but have troubles of my own with homing :) LOL
[19:34:40] <emperordane> haha
[19:34:42] <emperordane> nice
[19:35:28] <emperordane> because the scara layout is rare-er its been slow finding other projects to learn from
[19:39:50] <pcw_home> hatch789: integrators manual page 22 section 4.32
[19:43:10] <pcw_home> (in the 2.4 manual)
[19:44:42] <emperordane> <reading>
[19:45:08] <djdelorie> the hazards of writing your own servo control firmware... that all-too-familiar burning smell...
[19:46:30] <pcw_home> Run the drive at really Low VMotor?
[19:46:54] <djdelorie> run the drive into the end of the screw rod, then try REALLY HARD to keep up the rpm...
[19:47:28] <pcw_home> well thats what ferror (or current sensing) is for
[19:48:00] <djdelorie> that's the part I'm writing ;-)
[19:48:21] <djdelorie> I'm driving the motors with an FNB41560 and this is the second time I've let some of the magic smoke out, and THEY STILL WORK
[19:48:29] <djdelorie> tough chips.
[19:49:40] <pcw_home> We managed not to destroy our original IGBT module with our development (but we were running the 360V VBUS at 24V or so when testing)
[19:50:27] <djdelorie> in one of the app notes for it, they talk about liquid cooling them... they can take 450 Vmotor at 15 amps, I'm only giving them 60V at the moment, <1 amp, with a plain heatsink
[19:51:01] * djdelorie adds a TOO_HOT check in the main loop...
[19:51:57] <pcw_home> IGBT modules need a fair amount of cooling as they have high on voltage ~2v
[19:51:59] <pcw_home> so they are reall intended for 240/480 off line operation
[19:53:16] <djdelorie> yeah, the motors I'm using are for 160v (rectified 120 VAC). I've yet to warm *those* up.
[19:53:34] <emperordane> 160v? yowza what are you working on?
[19:53:38] <pcw_home> we finally killed our proto by forgetting to unplug the (120V) desklamp that was our brake-on indicator
[19:53:40] <pcw_home> when we cranked it up to 400V
[19:54:11] <djdelorie> http://www.delorie.com/photos/cnc/ but the motors were surplus so we're building around them
[19:54:51] <djdelorie> these are the BDLC driver boards I'm working on at the moment:
http://www.delorie.com/electronics/bldc/
[19:56:21] <pcw_home> Looks nice. We plan on using some of those modules on our next (smaller) drive
[19:56:42] <emperordane> is that an IXYS AWESOME BLOCK OF FETS i see?
[19:57:11] <djdelorie> ?
[19:57:16] <pcw_home> I wish Fairchild would make a 30A module like that with the built in thermistor
[19:57:38] <pcw_home> (other than their old old 5 KHz module)
[19:58:04] <emperordane> my bad, i thought the FNB41560 was something else
[19:58:09] <pcw_home> These are FSC
[19:58:13] <emperordane> IXYS makes something in a similar footprint
[19:58:25] <emperordane> 3phase mosfet hbridge shmorgatzborg
[19:58:54] <pcw_home> FNB41560 is fairly new (and IGBT not MOSFET)
[19:59:30] <pcw_home> IXYS make some nice larger modules
[20:03:33] <pcw_home> We had some interesting issues making the current loop not overshoot
[20:03:35] <pcw_home> ideally you would measure the motor inductance(and VBUS) to set the PI loop gain
[20:03:37] <pcw_home> but unfortunately motor inductance varies widely with rotor position on PMSMs
[20:23:39] <emperordane> @PCW_home, could you just rely on a large moving software average for the current loop
[20:36:30] <tom3p> #join #/r/bicycling
[20:36:39] <tom3p> gack!
[20:38:59] <pcw_home> I was thinking of autotune at startup but you cannot rely on the measure inductance
[20:43:54] <djdelorie> even so, if you're cutting through variable-density material, doesn't the PI math change depending on load?
[20:45:09] <pcw_home> not the current loop PI
[20:45:27] <djdelorie> oh, right, I'm thinking of the position PI
[20:47:17] <pcw_home> for the velocity or position PID loop you can do some tricks with differen tuning based on velocity (and robots often need to change PID VS position)
[20:47:19] <pcw_home> or use more sophisticated control algorithms
[20:54:57] <pcw_home> http://www.convolve.com/player.php?id=No+Sway+Crane+Technology is neat
[20:54:59] <pcw_home> (not control so much as input trajectory however)
[21:02:19] <hatch789> I have looked in the manual and there is some stuff on arcs but what is a good simple g-code for a circle? Can anyone direct me to a link for it? I have also checked our forum but I'm coming up empty
[21:02:50] <hatch789> I pulled this off of a forum but it doesn't work either: G02 I0. J-1. Fn.n
[21:26:39] <tom3p> try G91 I0J-1F10.0 in a virtual machine or be damn careful. ( will make a circle from where you are now, and pretty slowly )
[21:27:47] <tom3p> haha G91G02I0J-1F10.
[21:56:10] <Dave911> Convolve ... crane stuff .. very cool. That could be extremely useful for large overhead cranes moving expensive loads - like Aerospace
[22:02:47] <Connor> anyone here us the KL-5056's or KL-6852's ? Trying to get a sense of what the MAJOR difference is, and which one is better choice, if their is one.
[22:05:03] <jdhnc> that crane stuff is pretty cool
[22:06:39] <hatch789> tom3p, thank you that worked like a charm!
[22:07:51] <tom3p> do you understand it? the need for F value, and that G91 makes the XY values irrelevant?
[22:08:23] <jdhnc> I don't :)
[22:09:21] <jdhnc> wonder if the convolve no-sway would work with a long object being carried instead of just the crane block
[22:09:28] <tom3p> 1) it wont execute without a feedrate becasue its an interpolated motion, ok?
[22:10:16] <tom3p> 2) the G91 sex the begin point is X<here> and Y<here> ( oh yeah i ASSumed G17)
[22:10:22] <tom3p> sez
[22:11:29] <hatch789> it was awesome
[22:11:41] <hatch789> I changed j to + and it went up from the starting point
[22:11:52] <hatch789> I changed the F for faster feed and I changed the J size.
[22:12:00] <hatch789> so I can now make my circles any way I like pretty much
[22:13:05] <hatch789> I'm just starting to learn all of this stuff and it's amazing
[22:13:08] <jdhnc> I have done circles, but never used G91
[22:13:31] <hatch789> how do I use mdi to say from where I am move x +1 inch right?
[22:13:40] <hatch789> I keep getting movements of something stupid like .400
[22:13:51] <tom3p> where's JT's circle wizard?
[22:14:17] <tom3p> hatch789, G91 is the 'from where i am" magic word
[22:14:47] <hatch789> g1 x1 and g1 x0
[22:14:50] <hatch789> hmm
[22:15:05] <tom3p> G90 is the "from where i said to measure from" magic word
[22:15:33] <hatch789> I guess I need to say how do I go to a specific point from home
[22:15:46] <hatch789> like x2.0 and y2.0 from home
[22:17:57] <tom3p> http://linuxcnc.org/docs/html/gcode_main.html#sub:G2,-G3:-Arc
[22:18:13] <jdhnc> connor: max voltage is higher on one. I assume it would allow it to move faster if nothing else.
[22:18:54] <tom3p> 'home' may not be a good word here, call it your 'reference' ( where you measure from ) that position IS 0,0
[22:20:29] <tom3p> so to move to X2Y2 say "G0X2Y2" ( happens at rapid rate)
[22:20:40] <tom3p> or "G1X2Y2F10" happens at 10unitsper minute along a straight line, with both X&Y ending at same time
[22:21:13] <tom3p> again: read
http://linuxcnc.org/docs/html/gcode_main.html
[22:21:16] <hatch789> then how do I re-reference or something to show 0.0 again
[22:21:25] <hatch789> instead of some odd number that I'm on because I jogged here
[22:22:07] <tom3p> to go back? g0x0y0 (or G1X0Y0F10)
[22:23:29] <hatch789> that's doing nothing
[22:24:47] <hatch789> ok I am going to read much more on this. I just started tonight so I have a TON to learn
[22:24:52] <hatch789> but thank you for the help !
[22:24:54] <tom3p> to SET the position... lotsa ways, but G92X0Y0 makes HERE where 0,0 is
[22:25:49] <hatch789> ahhh that worked
[22:25:55] <tom3p> chg to G90 if nothing happens ( say 'move according to where i set 0', when, you want to measure from the ref, say G91 to msr from 'here'
[22:26:07] <hatch789> ok
[22:26:12] <hatch789> yeah I have a lot to learn
[22:26:26] <hatch789> but I need to cut some circles tomorrow before I do anything else
[22:26:37] <hatch789> I need to make a new heater. My shop is freezing
[22:26:44] <hatch789> and my mill was out of commission
[22:27:14] <hatch789> now it's all working again with LinuxCNC :)) which is amazing BTW
[22:28:09] <tom3p> aha it was called 'Arc Buddy' (JT's thingy)
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_EMC_G-Code_Generators#Arc_Buddy
[22:28:16] <tom3p> play there ^^^^
